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.

• Harris filed an application (with supporting exhibits) for experimental license to operate on various frequencies between 3 and 15 MHz to test an experimental high-frequency wideband waveform that is intended to operate at either 12 kHz bandwidth or 24 kHz bandwidth to allow faster data transfer via high-frequency communications.

• Harris also filed an application (with supporting exhibit) for experimental license to operate on 4.94-4.99 GHz in support of development of US Army’s Warfighter Information Network: Tactical (WIN-T) and Future Combat Systems (FCS) programs. Equipment is to consist of the HNRe2 Highband Network Radio, manufactured by Harris. Harris says the HNRe2 is comprised of four elements: 1) the Baseband Processing Unit, 2) the Highband RF Unit (HRFU), 3) an Inertial Navigation Unit (INU), and a GPS device. The HRFU further consists of an upconverter, a High-Powered Amplifier (HPA), a Switched Beam Antenna (SBA), a Low-Noise Amplifier (LNA), and a downconverter). The test network will consist of five fixed nodes and one mobile node. The FCC has asked Harris to justify extended testing in a band that is primarily allocated for non-government public safety use.

The video feed needs to be relayed to nearby receiving stations either on land or on vessels near the aircraft. The operation may require the aircraft to fly out over the Gulf to a maximum distance of 300 miles (483 km) from the New Orleans, LA area at altitudes up to 3,000 feet.” The application is inconsistent with regard to the specific frequencies requested. At one point it says three frequencies are being requested: 2,210, 2,220 and 2,230 MHz. At another point it says 2253.3 MHz. The application was granted on August 11.

• The Aerospace Corporation filed an application (with supporting exhibits) for experimental license to test synthetic aperture radar (SAR) on 92.05-99.95 GHz. As the applicant explains, in SAR radars, “the transmitter has a component of motion in a direction perpendicular to the beam, and the reflected signals are formed into an “image” of the scatterers when resolved into groups of scatterers in a two-dimensional map based on time-of-arrival (range coordinate) and Doppler frequency shift (azimuth coordinate).” The applicant notes that, in SAR, weather and vibration can mask man-made effects. Part of the research includes mitigating image degradation due to weather and vibration so man-made effects are more apparent. This application was approved on August 7.

• The Union Pacific Railroad Company filed an application (with supporting exhibits) for experimental license to conduct propagation testing on 220.725-220.750 MHz. The applicant explains that “the US rail industry is subject to a federal mandate to implement Positive Train Control (PTC) technology by the end of 2015. The industry is in the midst of a comprehensive development effort to realize this technology. A central component of PTC is wireless communications. The industry has identified 217-222 MHz as the band of operation for PTC, and some 220-222 spectrum licenses have already been acquired by an industry group. A concerted effort is underway to develop a radio specifically for this application, and we expect to have an authorized radio in early to mid 2011. However, as part of our deployment planning, we need to characterize the performance and propagation of modulated 220 MHz signals by doing field tests this year.”

Operation was to be on several frequencies between 24.615 and 26.475 MHz. The FCC rejected the application, saying that CODAR is currently being reviewed for its potential as a service requiring a frequency allocation. Until that determination is made, there will be no more experimental authorizations.

• Rockwell Collins filed an application (with supporting exhibits) for experimental license to conduct experiments to test waveforms for high speed data over high-frequencies. Testing is to include characterization of performance and actual wideband channel propagation characteristics. Rockwell Collins says it is a member of the Technical Advisory Committee for MIL-STD-188-110C and MIL-STD-188-141C standards revisions and new standard definitions, and the experimental authorization will enable verification of performance and inter-operability metrics in the standards. Operation is to be on many frequencies between 2.398 and 29.720 MHz.

• Rockwell Collins also filed an application (with supporting exhibits) for experimental license to test a prototype transmitter (as part of a transceiver) for the Automatic Dependent Surveillance-Broadcast (ADS-B) system, a surveillance technique for air traffic control and similar uses.

• 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.

• 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.

Antenna manufacturer dbSpectra files an application and supporting exhibit to conduct tests of passive intermodulation distortion (sometimes called the rusty-bolt effect). Through long-term testing of production antennas, the company hopes to reduce this source of interference in land-mobile radio systems. Testing will occur on various VHF and UHF frequencies at Lewisville, Texas.

Mokulele Research Corp. requests Special Temporary Authority to test broadband TCP/IP connections on millimeter-wave frequencies (46.75-46.95 GHz) between a ground station and aircraft. Testing is to take place in Haleiwa, Hawaii. This is a demonstration for NASA.

SouthConn Technologies requests Special Temporary Authority to demonstrate a remote control and monitoring system for street lighting. Operation is to be on 910.500-919.625 MHz at San Jose, California.

Sportvision applies to test an auto race track wireless data system to provide communications between vehicles and base stations. The system allows TV viewers to see the location of the cars in real time; the vehicles are equipped with GPS receivers and other sensors that generate a data packet every 200 milliseconds. Operation will be at 2395-2400 MHz. An accompanying exhibit states the technology is derived from IEEE 802.11b hardware.

SRC applies to test several SR Hawk surveillance radar systems on 16.21-16.50 GHz at Syracuse, New York.

Vista Research applies to test a radar-based surveillance system on 9.3-9.5 GHz at several sites in California. An accompanying exhibit says test project takes Furuno marine radars, modifies signal processing algorithms, and makes them part of a land-based sensor system. The system is to be deployed by the US Army and other government agencies for detection, tracking, and classification of people and vehicles. This is one of several instances in the last few months of marine radar being repurposed for non-marine applications in an experiment.

Walmart files an application to conduct RFID testing in Rogers, Arkansas on various frequencies between 800 and 956 MHz. A supporting exhibit says the current Bentonville, Arkansas lab works on North American RFID reader standards and frequencies. The Rogers lab will conduct RFID tests on frequencies and power levels allowed for RFID in Europe and the Asia-Pacific region. The goal of the research is to ensure that an RFID solution developed in the US can be deployed globally.

The biggest physical-layer change from today’s HRPD is that the reverse link is channelized in a new, narrowband manner. The typical 1.25 MHz spread-spectrum bandwidth is changed to 192 narrowband FDM channels, each channel 6.4 kHz wide. A terminal is assigned one or two of these channels. These channels are orthogonal, reducing intra-cell interference and improving the link-budget. Narrowband channels reduce search time and need less link-margin than wide-bandwidth channels. New coding and reduced overhead improves link efficiency for small packets. Changes to the MAC layer also help.

In HPRD, forward link transmission relies on a Channel Quality Indicator sent periodically by the terminal. xHRPD can send a constant CQI value for a longer period of time to allow coherent combining of long-delayed, weak CQI symbols at the access network. This means the data rate does not change as often on the forward link.

To accommodate long satellite path delays and large satellite cells, a new narrowband Access Channel uses the Slotted Aloha protocol. The modified reverse link power-control channel operates at 50 bps instead of the typical 150 bps. Hybrid ARQ is disabled in xHRPD protocol due to the long path delays.

This framework remains open in 3GPP2. Discussions are to continue at the next meeting in late January.
