• National Public Radio filed an application with exhibits for experimental license to evaluate the feasibility of using a Cognitive Modulator. This is envisioned as an alternative to consumer FM modulators long used to allow audio from a personal electronic device to be played through a vehicle’s FM radio. These modulators have their drawbacks: they can cause interference to other FM listeners, FCC rules limit their power such that it can be difficult for them to overcome interference, and they may need to be retuned as the vehicle travels into range of new, interfering FM stations. Preliminary testing led by NPR suggests a Cognitive Modulator operating at 87.7 MHz may present a solution to the above service problems. Such a device would sense the amount of interference and noise (I+N) at or around 87.7 MHz and adjust its transmitter carrier power to provide a desired C/(I+N) in a vehicle’s FM radio. Experimental operation will be in New Haven, Connecticut on 87.7 MHz

• National Public Radio filed an application (with supporting exhibits) for an experimental license to operate on 87.7 MHz in Philadelphia and San Francisco to test a “cognitive modulator” that would operate below the current FM band as an alternative to current consumer FM modulators. These modulators plug into the earphone jack of an audio device and transmit the audio at low power to an FM radio, often in a car.

The performance of these devices is usually mediocre at best. The FCC limits them to very low power. They’re tuned initially to unused FM frequencies that become occupied as the car moves, causing interference. HD Radio, which overlays a digital signal on the analog channel, increases interference; furthermore, HD Radio interference has no audible content and, to the listener, appears to be an unused channel causing confusion when selecting a frequency for the modulator. The modulators can also cause interference to other FM listeners.

The cognitive modulator to be tested would operate on 87.7 MHz, just below the FM band. It would measure interference and noise and adjust its transmitter power to provide a desired signal quality in car’s FM radio. In addition to testing the effectiveness of the new modulator, any interference from the modulator to other services would be evaluated. Services that could be impacted (but probably won’t) include FM broadcast stations on 88.1 MHz and digital TV stations on Channel 6 (82-88 MHz). Presumably, successful test results would be used in support of a request to the FCC to allow the manufacture and sale of the devices.

It has a parabolic reflector 14.6 inches in diameter, and uses tracking mechanisms to keep it oriented toward the satellite. The market for this terminal includes small and medium-size vessels over 40-feet in length, including from the private, commercial, public safety, and defense sectors.

• Raysat Antenna Systems filed an application (with supporting exhibits) for special temporary authority to operate on 14.0-14.5 GHz in the continental United States. Technical details are not disclosed by the FCC due to a confidentiality request by Raysat. This is likely a test of a two-way mobile antenna for fixed satellite use.

• The University of Texas at Austin filed an application (with supporting exhibits) for experimental license to conduct tests of millimeter-wave propagation at 35-41 GHz and 57-63 GHz. The data collected are to be processed and integrated into published channel models to assist other researchers and designers.

• SET Corporation, a subsidiary of SAIC, filed an application (with supporting exhibits) for special temporary authority to operate on 93.5 GHz in and around Manassas, Virginia. This is to support manufacture of “multi-sensor products designed to counter the growing number of deadly security threats faced by homeland security and defense customers.” Further specifics are not disclosed by the FCC due to a confidentiality request by SET.

In Boston, Verizon charges about $2,200 per month for symmetrical 10 Mbps business service via fiber; netBlazr charges $189 per month for equivalent service using its hybrid fiber/wireless system. Less-expensive shared plans, including one that’s free, are available for businesses with lower-priority traffic.

The demand is, in part, from the smart grid community, who like it for linking to smart meters because of the band’s greater range and lower obstruction losses.  A problem, though, has been lack of interoperability. Each vendor has its own implementation, and smart grid customers don’t want to be tied to one vendor.

Today the IEEE Standards Association’s Standards Board approved a request by IEEE 802 Working Group 802.11 to start a project that will amend the 802.11 standard to include sub 1 GHz operation. This project, under new Task Group 802.11ah, does not include TV white space frequencies; that’s being handled under Task Group 802.11af.

The most important thing this amendment will do is establish standard RF channel widths and center frequencies. Because 802.11 is an international standard, non-US allocation schemes will be considered as well.

At least one FCC observer has noted an uncharacteristic level of hype in today’s announcements. The FCC calls it “super Wi-Fi,” and adds the “potential uses of this spectrum are limited only by the imagination.”

Over two years ago, Google called it “Wi-Fi on Steroids.” It was later picked up by the popular press. Not all agree; it’s “Wi-Fi on Crutches” according to one who dares to consider the realities of physics and economics.

I’ll call it “Wi-Fi on Caffeine,” at least with respect to better range and coverage — if not data rates — compared with current Wi-Fi equipment. This is partly due to operation in the UHF-TV band instead of the 2.4 GHz band. In major markets and their suburbs, there will be few or no channels available for white space use. In rural areas and other less dense areas, the technology will be a good fit with Wireless Internet Service Providers (WISPs) and other longer-distance applications.

Cellular operators would like some of the white space on a licensed basis for backhaul in rural areas. They didn’t get it today, but the FCC is actively considering it and we may hear more on that by the end of the year.  No way are all these vacant channels going to be occupied by internet services in the most rural areas, so the proposal of the operators makes sense.

In IEEE 802, Working Groups 802.22 and 802.11 are working on standards that can be used by equipment in these applications; 802.22 may be the one with longer range. Working Group 802.19 is trying to facilitate coexistence between the two. Now, there are asymetric interference effects, which is causing friction between the two groups beyond the normal competition. (802.22 takes the harder interference hit.)

There will be other standards and equipment as well. The white space concept is international, but unique to each area of the world.

Equipment is not easy; it’s challenging to develop sufficiently-broadband power amplifiers and antennas, and to meet the emission mask in a cost-effective manner.

Another challenge is developing a business plan when 120 MHz of TV spectrum could be taken away under the National Broadband Plan.

Paragraph 3 of today’s Memorandum briefly outlines what the Commission considers to be the main points of today’s action. I reproduce the text of that outline below. Please refer to the complete document for more information, and consult with a communications attorney before acting on any of this information.

By today’s decision, the FCC is taking the following actions:

“Protection Criteria for Incumbent Services

• Modifying the protection criteria for low power auxiliary stations such as wireless microphones to reduce the required separation between such devices and unlicensed personal/portable devices operating in Mode II.

• Modifying the definition of the receive sites entitled to protection outside of a television station’s service area to include all multi-channel video programming distributors as defined by our rules.

• Reserving two vacant UHF channels for wireless microphones and other low power auxiliary service devices in all areas of the country.

• Allowing operators of event and production/show venues that use large numbers of wireless microphones on an unlicensed basis that cannot be accommodated in the two reserved channels and any others available at that location to register the sites of those venues on TV bands databases to receive the same geographic spacing protections afforded licensed wireless microphones.

• Restricting fixed TV bands devices from operating on locations where the ground level is more than 76 meters above the average terrain level in the area.

TV Bands Devices

• Eliminating the requirement that TV bands devices that incorporate geo-location and database access must also listen (sense) to detect the signals of TV stations and low power auxiliary service stations (wireless microphones). As part of that change we are also revising and amending the rules in several aspects to reflect use of that method as the only means for determining channel availability. While we are eliminating the sensing requirement for TVBDs, we are encouraging continued development of this capability because we believe it holds promise to further improvements in spectrum efficiency in the TV spectrum in the future and will be a vital tool for providing opportunistic access to other spectrum bands.

• Adopting power spectral density limits for unlicensed TV bands devices.

• Modifying the rules governing measurement of adjacent channel emissions.

• Restricting fixed TV bands devices from operating at locations where the height above average terrain of the ground level is greater than 76 meters.

TV Bands Database

• Requiring that communications between TV bands devices and TV bands databases, and between multiple databases, are secure.

• Requiring that all information that is required by the Commission’s rules to be in the TV bands databases be publicly available.

Use of TV Channels

• Amending the rules to protect Canadian and Mexican stations in the border areas by including those stations in the TV bands database as protected services.

• Changing the protection zone for the radio astronomy facility near Socorro, New Mexico to a rectangular area.

• Declining to grant a request by FiberTower to set aside TV channels for fixed licensed backhaul use.”

• INOVA Geophysical Equipment Limited filed an application (with supporting exhibits) to test a proprietary mobile radio system in the 30-36 MHz and 150-174 MHz bands. The radio links would be used to control remote geophysical seismic recording equipment, which INOVA manufactures. At the end of testing, INOVA plans to put the radio equipment into production and lease it to customers.

• Fortress Technologies filed an application for experimental license to test several of its secure mesh-networking products developed for military applications. Several exhibits are included but they are not publicly available due to a confidentiality request. Operation is to be on 4.9425-4.9875 GHz.

• The Port Authority of New York and New Jersey filed an application for special temporary authority to operate on 5250-5500 MHz while testing to find the best location for an Elta 2127 ground surveillance and movement detection radar at JFK Airport. Three similar applications were filed for testing at La Guardia, Newark, and Teterboro Airports.

• General Dynamics Armament and Technical Products filed an application (with supporting exhibit) for special temporary authority to operate on 1760-1850 MHz and 2200-2300 MHz to conduct testing based on Department of Defense requirements for fully-digital data links for small unmanned aircraft systems to allow for higher concentrations of unmanned aerial vehicles (UAVs) operating in the same battle space. A new data link is to be tested. The new data link is compatible with ground based Remote Video Terminals (ROVERs) allowing for real-time reception of video imagery by ground troops.

• Fujitsu Ten Limited filed an application (with supporting exhibits) for experimental license to operate on 76-77 GHz. The exhibits are not available for viewing, presumably because of a confidentiality request. From other information, this appears to be a test of radar for safe-driving assistance systems. This application was granted on August 27.

• Sikorsky Aircraft filed an application (with supporting exhibits) for experimental license to operate on 30-400 MHz. This is to test Rockwell-Collins AN/ARC-210 radios on military helicopters being sold to the United Arab Emirates (UAE). According to the applicant, the “Rockwell-Collins AN/ARC-210 radios will have several unique frequency hopping waveforms which are proprietary to Rockwell-Collins. These waveforms are called TALON and Quicklook waveforms, respectively. The AN/ARC-210 TALON/Quicklook radios will be used aboard the [helicopters] to communicate with UAE ground forces. The Quicklook frequency hopping waveform is used in the 30-90 MHz band. The TALON frequency hopping waveform is used in the 90 to 400 MHz bands.”

• Abbott Diabetes Care filed two applications to test equipment at 433 MHz. The company has requested confidential processing of its application, and few other details are publicly available from the FCC. This may be related to Abbott’s wireless glucose monitoring products. The company announced in April 2010 that it had supply problems with a wireless product.

• WCA Holdings III, LLC filed an application (with associated exhibits) for special temporary authority to operate on 14.00-14.47 GHz for on-ground and flight testing of a single aircraft earth station antenna. This is to assist with Federal Aviation Administration Supplemental Type Certification testing, as well as further testing and demonstration of the functionality of the antenna with the eXConnect Ku-band Aeronautical Mobile-Satellite Service (AMSS) system. WCA has partnered with Panasonic Avionics Corporation, proponent of the eXConnect System.

The eXConnect System is Panasonic’s. It is designed for in-flight passenger internet access and other communication services. It can be looked at as a replacement for the now-defunct Boeing Connexion system. Lufthansa, for one, plans to use eXConnect on the majority of its 70 aircraft already fitted with Connexion hardware.

This application was received on August 6. On September 1, the application record was updated to note that WCA’s operating partner, Panasonic Avionics Corporation, is in the process of developing a detailed coordination agreement with NASA to protect existing and future Tracking and Data Relay Satellite System (TDRSS) operations from potential interference from Ku-band AES operations. The application was granted on September 7.

• Pro Xplor Services filed an application but few details are available due to a request for confidential processing, which FCC staff has asked the company to justify. It also requested a nationwide license, and FCC staff has suggested that a smaller operating area would suffice.

On July 7 of this year, the FCC denied the company’s request for waiver of the technical rules in Section 90.259 of the Commission’s Rules in order to permit certain proposed secondary telemetry operations.  At the time, it had sought authorization to operate in parts of Arkansas, Louisiana, and Texas on 217/219 MHz frequencies with up to fifteen watts output power on 600-kilohertz and 800-kilohertz channels.

• INSITU filed an application (with supporting exhibit) for special temporary authority to test the SeaLancet IP network radio in a flight test on 2367 MHz.

• Boeing filed an application (with supporting exhibits) for special temporary authority to test an Electronic Support Measures (ESM) system installed on a modified Boeing 767. Operation is to be on 800 MHz, 5.4 GHz, and 9.4 GHz. “The test involves personnel walking around the aircraft with a signal generator and horn antenna directed at the aircraft to stimulate ESM sensors mounted on the aircraft skin.” This application was granted on August 27.

• Sensus Spectrum filed an application (with supporting exhibits) for special temporary authority to test Smart Grid devices on 410-430 MHz. Sensus manufacturers similar products on 900 MHz for the US market. The requested frequencies are for testing of devices intended for Europe and the Middle East.

• Lockheed Martin filed an application (with supporting exhibits) for experimental license to operate on 9.595-9.750 GHz and 10.15-10.43 GHz to operate a ground station used to exchange data with an airborne system. The equipment is said to be an improved version of a system previously delivered to a customer under the US Government Foreign Military Sales for the Peace Krypton program. According to the Federation of American Scientists, the “mission of the Peace Krypton system program (known internally to Lockheed Martin Corporation as the Eagle program) is to collect reconnaissance imagery of selected areas during long range missions using an airborne Synthetic Aperture Radar (SAR) imagery intelligence collection system.”

• Bowling Green State University filed an application (with supporting exhibits) for experimental license to use a Furuno FR-1525Mk3 marine radar to track bird and bat activity in areas of existing and planned wind turbine development as well as comparative control sites. Operation will be on 9.3-9.5 GHz.

• SET Corporation, founded by former DARPA scientists and now a subsidiary of SAIC, filed an application (with supporting exhibits) for experimental license to operate in and around Denver, Colorado on 35.75 GHz. Details of the proposed test are confidential.

• Raytheon Missile Systems filed an application (with supporting exhibit) for experimental license to test advanced antennas operating in the 80-200 MHz range. The testing will be used to determine three-dimensional far-field radiation patterns of the antennas.

UWB, as authorized by the FCC, operates across 3.1 to 10.6 GHz, with very low power at any one frequency; its tendency to cause or receive interference is very low.

IEEE 802 attempted to create a UWB standard in IEEE 802.15.3a but did not, as neither of two competing proposals reached the necessary voting threshold for approval. One of the competing proposals, Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM), has since seen some consumer success in Wireless USB, which is based on a platform maintained by the WiMedia Alliance; data rates are up to 480 Mbps at a range of about 10 feet.

UWB was eventually standardized in IEEE 802.15.4a, where it exists as an alternative physical-layer to standard IEEE 802.15.4-2006, a standard for very low power, low data rate devices. (The IEEE 802.15.3 family is for higher data rates with higher power consumption.) It uses what was the other competing proposal in 802.15.3a, Direct Sequence UWB (DS-UWB). This standardized form of UWB has been commercialized for asset tracking and other location services, but not yet for consumer applications.

As Lazarus says, though UWB is successful in several applications outside the home, it has not made as much progress in the consumer market. A big reason for this is that UWB’s competitors were not so encumbered with regulatory and standardization delays.

• Standard IEEE 802.11n-2009 (high-throughput Wi-Fi) was approved a year ago with uncoded bit rates up to 600 Mbps in a 40 MHz bandwidth at 2.4 or 5 GHz.

• The Wireless Home Digital Interface (WHDI), which operates in 40 MHz of bandwidth in the 5 GHz unlicensed band, was standardized late last year by the WHDI Consortium. The targeted market is transmission of uncompressed (better-quality) HD video, with data rates up to 3 Gbps. IEEE 802 was not involved, though the technology is similar to 802.11n.

• There are two new millimeter-wave technologies that offer multi-gigabit data rates. These 60-GHz technologies are not direct competitors with UWB, but some overlap in applications could emerge. The data rates are much higher, but 60 GHz is blocked by most any obstruction, and power consumption is high making it unsuitable for mobile devices at this time. As with WHDI, the main market is the transmission of uncompressed HD video.

WirelessHD operates in the 57-64 GHz unlicensed band and is based on the IEEE 802.15.3c-2009 standard that was published about a year ago. The Wireless Gigabit Alliance is another 60 GHz proponent; its specification is to be based on the IEEE 802.11ad standard, which is under development and should be completed around the end of 2012.

If someone tried to standardize UWB in IEEE 802.15.3 today, they would have a better chance of success due to meeting process improvements. In making decisions in IEEE 802, it has traditionally been one-person, one-vote. That has sometimes motivated companies to send as many as possible to the standards meetings so they can earn voting rights and vote as a block, a practice frowned on by ANSI, IEEE 802’s accrediting body. Since the failure of the UWB standardization in 802.15.3, and because of evidence of block voting in other groups, IEEE 802 has modified its voting procedures to make block-voting harder. Everyone participating in the meetings now has to declare an “affiliation,” the definition of which is carefully worded to lead to the primary entity paying the participant. Consultants, for example, have to declare affiliation with their client, not their consulting firm; they often didn’t do this before. If roll-call votes show evidence of block voting, the group may be switched to entity voting (e.g., one company, one vote). That helps. IEEE 802.20 got bogged down, switched to entity voting, instantly made progress and completed its standard.

With these and further process improvements, IEEE 802 is a good home for these unlicensed standards. One advantage is that all IEEE 802 wireless projects are required to address coexistence with other IEEE 802 wireless standards. That’s hard, as many are using the same spectrum, but the affected groups sometimes can make accommodations with each other to reduce mutual interference. Also, many companies prefer the more-open process of an accredited standards development organization. The decision to go it alone or with a proprietary specification, however, is ultimately a business decision.

UWB remains unique in terms of its interference-resistant characteristics. As more RF devices enter the home, as they will with increased machine-to-machine communications, UWB could help as the more-popular relatively-narrowband devices increasingly interfere with each other. UWB may then become successful in the home out of necessity, if not as an option.

• AAI/Textron Systems Corporation filed an application (with supporting exhibits) for experimental license. The company wants to test its Shadow 200, Aerosonde, Orbiter and other unmanned aircraft systems. This is related to work for the United States Marine Corp. Operation is to be on 310-390 MHz, 902-928 MHz, 1090 MHz, 1350-1390 MHz, 1700-1859 MHz, and 4400-4999 MHz. Transmitting equipment is manufactured by Microhard Systems Corporation, Free Wave Technologies, Advanced Microwave Products, Global Microwave Systems, and Microair Avionics.

FCC staff has asked for several items of information before approving the application. The FAA operates in the frequency bands 328.6-335.4 MHz, 1090 MHz, and 1215-1390 MHz; FCC staff asks for coordination of these bands with the FAA Regional Office. In addition, the frequency bands 225-328.6 MHz and 335.4-399.9 MHz are used for military purposes, and the applicant was asked to coordinate with NTIA’s Interdepartment Radio Advisory Committee (IRAC).

• AAI/Textron Systems Corporation also filed an application (with supporting exhibits) for special temporary authority to operate on 420-450 MHz and 2000-2400 MHz for a government project apparently involving the Orbiter miniature unmanned aircraft system. There is not much information about the proposed operation, and FCC staff has asked for more details.

In correspondence to the applicant, FCC staff notes that the “Aerospace & Flight Test Radio Coordinating Council (AFTRCC) oversees the frequency bands; 1435-1525 MHz, 2310-2320 MHz, and 2345-2390 MHz. These frequency bands need to be removed or need to be prior coordinated.”

• Sportvision filed an application (with supporting exhibits) for special temporary authority for testing of an automobile race track wireless data system that is to provide data communications between vehicles in a race track and one or more fixed base stations installed along a track. Operation is to be on 2395-2400 MHz.

One application seen for this system is video image enhancement for television broadcasting of automobile racing events. The would allow television viewers to see, displayed on screen, the real-time location of cars during a racing event.

The vehicles would be equipped with GPS receivers and other sensors that generate a data packet every 200 milliseconds. The wireless system would collect those packets and deliver them to a control station in real time. “The radio itself is a direct sequence spread spectrum unit, using production radios for 2.4 GHz. The system may ultimately be deployed on an unlicensed basis in the 2.4 GHz band or elsewhere, but the high noise levels in that band in the test locations (commercial automobile race tracks) are unsuitable for development and testing of the product.”

“An Intersil baseband processor performs the Direct Sequence modulation and demodulation. It is part of a five-chipset developed for the 802.11b standard. It uses 1/4th of the standard 802.11 speed resulting in a narrow occupied RF bandwidth.”

The frequency band requested is allocated on a primary basis to the Amateur Radio Service, and coordination is to be performed with the ARRL. This application was granted on June 4.

• Motorola filed an application (with supporting exhibit (as amended)) for special temporary authority to “test, evaluate and demonstrate a prototype radio communications system designed to support the internal communications requirements, including public safety-related communications, of an electric power generation and transmission cooperative in the Commonwealth of Kentucky.”

According to Motorola, “[o]peration under this experimental STA will be conducted on a non-interference basis on a limited number of 12.5 kHz channel pairs in the 151.4725-154.5675 MHz band and the 157.1875-162.9625 MHz band.”

• Raytheon Network Centric Systems filed an application (with supporting exhibits) for experimental license. Raytheon says it is working to build a “NetWarrior Communications System” using GSM technology. The primary use for this experimental license would be to test and evaluate this system while in development and conduct demonstrations for military and government officials.

The system is called GSMnet and is described as a unique communication solution that provides the ability to create a self-contained, privately managed mobile network based on GSM cellular standards. The enabling technology of GSMnet is said to allow military personnel to manage mobile phone access on the GSMnet communications infrastructure, delivering seamless cellular communications coverage to deployed military personnel and critical incident responders in remote or hazardous environments or when conditions have rendered existing GSM cellular networks inaccessible.

Operation is to be on 1922.6, 1927.4, 2112.6, and 2117.4 MHz. This application was granted on June 15.

• Sierra Nevada Corporation filed an application for special temporary authority to conduct flight testing of X-NET Air WiMax transceiver radio devices. The flight tests will determine the range of the data communications that can be achieved and the data throughput that can be achieved at different ranges.

As background, the C4N (Command, Control, Computers, Communications, and Networks) Division of the Sierra Nevada Corporation has developed an air-ground data communications link under contract with the USAF Rivet Joint aircraft operations as a part of the Big Safari Program. The Sierra Nevada equipment is called the X-NET Air System. It is a dual channel FDD radio link. Operation is to be on 2675 and 2685 MHz. This application was granted on June 28.

• Raysat Antenna Systems filed an application (with supporting exhibits) for special temporary authority to operate up to five Land Mobile-Satellite Service (LMSS) earth stations with the AMC-5 and AMC-6 satellites at 79° W.L. and 72° W.L., respectively. The company seeks to test and demonstrate the new SR70 earth terminal, a single-panel, Ku-band array antenna in connection with Department of Defense/Logistics Innovation Agency (DOD/LIA). Operation is requested at 14.0-14.5 MHz.

“The SR-70 antenna technology builds upon RAS’s proven antenna technology for mobile applications. The major enhancement is in the antenna panel which is capable of simultaneous Ku-band transmission and reception within the 14.0-14.5 GHz and 11.7- 12.7 GHz bands, respectively. The antenna allows tracking in three axes, azimuth, elevation and polarization.”

“The antenna consists of a single 6 inch by 6 inch panel array which is mounted on a rotatable platform. The platform rotates in azimuth to orient the panel towards the satellite. The panel also tilts to set the elevation angle. Finally, the antenna has a polarization control mechanism which sets the correct polarization angle for both transmit and receive.”

“During operation, the antenna uses a built-in GPS receiver to determine its position on the earth. It then uses the geographical position and the longitudinal position of the satellite to determine the appropriate elevation angle. Once the elevation angle is set, the antenna rotates in azimuth. During the scanning process the antenna receives Eb/No information from the modem to verify that the target satellite has been acquired. Once the satellite is acquired, the antenna dithers in both azimuth and elevation by ±2.0° to maintain peaking on the satellite and the transmission is enabled. The antenna also has internal 3-axis gyroscopes and 2-axis inclinometers to help with the tracking while the antenna is in motion.”

This application was granted on June 16.

• Lockheed Martin filed an application (with supporting exhibits) to experiment with a swept-frequency radar system operating at various frequencies between 1.0 and 15.4 GHz. The radar transmit-and-receive system will be coherently frequency step-chirped from the start frequency to the final frequency, with a pulse width of 95 ns. Other details are said to be classified; Lockheed Martin has requested confidential treatment of this application, and FCC staff has responded to the company asking for justification.

• Aircell, a provider of Wi-Fi service aboard aircraft (under the GoGo brand) filed an application (with supporting exhibits) for experimental license to conduct FAA-required tests to determine the susceptibility of aircraft avionics to interference from radio frequency emissions from consumer devices operating in Wi-Fi bands. Aircell says it must demonstrate conformance to those standards to receive FAA Supplemental Type Certificates necessary for the deployment of its service aboard commercial airliners. Testing is to be on 2400.0-2483.5 MHz, 5250-5350 MHz, and 5725-5825 MHz.

Aircell says that “[p]ursuant to Documents DO-294B and DO-160 of the Radio Technical Commission for Aeronautics (RCTA), and the FAA, standards for testing the susceptibility of avionics to interference have been set. To comply with these standards, tests within an aircraft must radiate at the legal maximum power authorized for the radiating device, plus the link budget of the highest gain antenna permitted, times the number of simultaneous radiating devices. For the purpose of Aircell’s tests, the math computes a 1 watt signal into a 6 db gain antenna times three wireless access points (WAP). That comes to 30 dBm + 6 dB = 4 watts X 3 WAPs = 12 watts. Since the 12 watt signal exceeds the allowed limits for unlicensed devices, an Experimental License is required.”

• Clearwire Spectrum Holdings III filed an application (with supporting exhibits) for experimental license to test WiMAX IEEE 802.16m technology in the Phoenix, Arizona market. (The 802.16m standard is now being finalized in IEEE 802.) Clearwire says it is evaluating 802.16m and other 4G technologies “as a potential technology evolutionary strategy.” Clearwire is planning to test overlay 802.16e WiMAX using 10 MHz channels, Frequency Division Duplex (FDD) using 20 MHz channels, and Time Division Duplex (TDD) using 20 MHz channels. Operation is to be on 2496-2690 MHz.

Equipment from “many vendors” will be evaluated. Many tests are to be performed, including those for end-to-end system performance, mobility management, MIMO, scheduler and QoS, base-station RF characteristics, self-organizing networks, and VoIP. This application was granted on June 29.

• Flight Research, Inc. filed an application (with supporting exhibit) for experimental license to operate on 2.4 GHz to send NTSC video from a small aircraft to ground. A Strain Security transmitter is to be installed in a Cessna 150 aircraft operating as a surrogate UAV. (SUAV). The SUAV is to fly locally as an academic exercise for students in a UAV flight test short course that is part of the National Test Pilot School. Students will execute tests in remotely-piloted and command-directed modes from a ground control element, collecting data employing typical flight test techniques and evaluating the system. Part of that training involves sending video from the aircraft to the ground. (Much of this information was not in the original application but was supplied by e-mail to FCC staff later.)

• Global Technical Systems filed an application (with supporting exhibits) for special temporary authority to test an aircraft-mounted ground-penetrating radar. In the test, a metal target will be buried 6 feet underground and illuminated by the radar for 60 seconds on each pass of the aircraft, which will be flying at 10,000 feet above ground. Data will be collected for ground processing.

Correspondence between the applicant and FCC staff reveals some confusion as to the frequency of operation. It seems it will be in the 1250-1400 MHz range.

• InterDigital filed an application (with supporting exhibits) for experimental license to conduct research using vacant spectrum in the television broadcast bands (the “white spaces”) for indoor testing of fixed and portable white-space devices. InterDigital says its “goal is to develop technology and enable products for efficient use of bandwidth by combining the advantages of multiple radio access technologies and frequency bands.” “InterDigital plans to test technology that provides cost effective options for wireless distribution of various data types including, for example, broadband content (video) and machine-to-machine packets.” “Another goal of the experimentation is to develop and validate cognitive radio technology.”

In correspondence to the applicant, FCC staff asks for details on how InterDigital plans to prevent interference to TV licensees. The links above are for an application for operation in Melville, New York. An essentially-identical application was also filed for operation in King of Prussia, Pennsylvania.

• Panasonic Avionics Corporation filed an application (with supporting exhibit) for experimental license for ground and flight testing of up to twenty aircraft earth stations (AESs) of two AES types – ten MELCO reflector terminals and ten Aura LE terminals – to further test and demonstrate the functionality of its eXConnect Ku-band Aeronautical Mobile-Satellite Service (“AMSS”) system. The company says eXConnect is to provide broadband internet access, real-time video content, voice and other services aboard commercial aircraft.

The company does not envision formal launch of the eXConnect system onboard U.S. commercial airlines in the near term. It is, however, preparing an FCC blanket license application for authority to operate eXConnect AESs on a full commercial basis. In the meantime, the company wants to conduct limited market studies. Operation is to be on 14.000-14.470 GHz.

• Virginia Tech Mobile and Portable Radio Research Group (MPRG) filed an application (with supporting exhibits) for special temporary authority to perform experiments related to new TV band (white space) devices.

The Group intends to test prototype TV white space devices to determine how their operation will affect other co-channel and adjacent-channel users, such as wireless microphones and other professional audio equipment that is commonly operated in the television bands. Frequencies will be coordinated prior to operation by the local SBE frequency coordinator. Operation is to be on 512-608 MHz and 614-698 MHz.

• Lockheed Martin filed an application (with supporting exhibits) for special temporary authority to test a Harris model RF-7800S-TR radio as a potential weapon data link to provide in-flight moving target location updates to a weapon to facilitate engaging moving surface targets. The objective of the test is to evaluate the affects of message rate, latency and bit-error-rate on target engagement and determine a realistic target engagement envelope. A larger goal is to demonstrate this class of radio as a viable option to improving moving target strike effectiveness and support the development of low cost, low collateral damage weapons. Operation will be on 350-450 MHz.

• GlySens Incorporated filed an application (with supporting exhibits) for experimental license to test implantable electronic medical devices on 433.92 MHz. The company has requested confidential processing of its application, so few other details are publicly available from the FCC. This application was granted on June 28.

This is likely related to the company’s announced development of a long-term continuous glucose monitoring system that is designed to provide an unobtrusive means to continuously track glucose levels in people with diabetes. The system is has two parts: a long-lived fully-implanted sensor and an external monitor with a display. The sensor continuously monitors glucose levels in subcutaneous tissue, which are correlated to blood glucose levels. The sensor transmits the glucose measurements wirelessly to the  external display device. This device indicates the current blood glucose level, shows a historical chart of the previous blood glucose values, provides adjustable automatic warnings of high and low blood glucose readings, and stores information for analysis.

• Space Exploration Technologies Corp. (SpaceX) filed an application for special temporary authority to use telemetry, ranging, and video transmitters for the second launch campaign of the Falcon 9 launch vehicle. The vehicle will be launched for NASA from Complex 40 at Cape Canaveral Air Force Station, under launch authorities granted by the U.S. Air Force and Federal Aviation Administration. SpaceX is under an active STA for this, but due to delays the STA will expire before launch. This application is to continue that authority, as the FCC does not grant extensions for experimental STAs.

SpaceX will utilize a telemetry and video transmitter on both the first and second stages of the vehicle, plus a C-band ranging transmitter on the vehicles second stage. The first stage will begin transmitting 15 minutes prior to launch and remain active for 2.9 minutes after launch. The second stage will continue transmitting for up to 2 hours after launch. Operation will be on 2213.5, 2221.5, 2251.5, 2273.5, and 5765.0 MHz.

In correspondence to the applicant, FCC staff says that the applicant will have to obtain an orbital debris statement from Space Exploration Technologies, Inc., in accordance with 47 CFR, Part 5.63(e) which states, in part, that “Applicants for an experimental authorization involving a satellite system must submit a description of the design and operational strategies the satellite system will use to mitigate orbital debris.”)

• Professor David Miller from MIT filed an application (with supporting exhibits) for experimental license to transmit spacecraft telemetry on 2.4000-2.4836 GHz. This is in support of testing of the CASTOR (Cathode/Anode Satellite Thruster for Orbital Repositioning) satellite. Testing is to validate the performance and application of Diverging Cusped Field Thruster (DCFT) technology. This will be achieved by taking on-orbit state data to compare the degradation experienced by the DCFT to that of similar technologies such as Hall thrusters.

• RLM Communications filed an application (with supporting exhibits) for experimental license. Operation is to be on various broadcast bands from 540 kHz to 806 MHz. The company says it is “providing the United States Army Special Operations Command (USASOC) research and development support in the areas of Joint Integration and Compatibility Development System (JCIDS) and Special Operations Forces Integration Development System (SOFCIDS) requirements development, product evaluation and systems testing and training. RLM will be providing training documentation, technical writers, training specialists, electronic technicians and other media support professionals in the upcoming Design Testing (DT), Operational Testing (OT) and new equipment training (NET) for a family of electronic broadcast systems which encompass broadcast radio in AM, FM, SW and television in UHF and VHF analog television and digital television. The nature of the activity will include erecting the antenna system several times, startup up the transmitter and increasing ERP into a dummy load and into the radiating” antennas.
