Experimental Radio Applications at the FCC

This summarizes a selection from 289 applications for the Experimental Radio Service received by the FCC during April, May, and June 2012. These are related to AM, high-frequency propagation, ultra-wideband, frequency-hopped VHF, managed access, small satellites, radar, MIMO, TV white space, low-power FM, stadium wireless service, GSM, and DTV. The descriptions are sorted by the lowest frequency found in the application.

Experimental Radio Applications at the FCC

This summarizes a selection from 215 applications for the Experimental Radio Service received by the FCC during October, November, and December 2011. These are related to AM broadcasting, FM broadcasting, spread spectrum on HF and VHF, unmanned aerial vehicle control, electronic warfare support, small satellites, white space technology, video production, managed access, TV interference, RFID, and radar.  The descriptions are listed in order of the lowest frequency found in the application.

Filling the Spectrum Pipeline

In my last post I looked at how the U.S. is behind some other countries in having new mobile broadband spectrum in the pipeline, according to a tally prepared by CTIA. What’s the status of candidate new bands?

Wired versus Wireless

The following is my response to a query on LTE versus wired, and the user experience. It capsulizes my current thinking, which evolves.

To your point, I don’t see LTE being competitive with wired in terms of speed or reliability today or in the future. You take the hit there for the convenience of mobile or portable operation. There’s a notion that if we just add enough base stations and repurpose enough spectrum to LTE, we can replicate the home wired experience in the mobile environment, but I don’t think that’s practical. The throughput from an LTE sector is divided among all users in the sector. If everyone wants to watch the Super Bowl at once on LTE, forget it (unless the LTE broadcasting standard is implemented, which let’s everyone watch the same channel like today’s TV (cough)). On FIOS or cable, the Super Bowl is no problem.

Spectrum, Data, Capacity, and PR

A couple of days ago the Mobile Future coalition posted a short video on YouTube advocating the allocation of more spectrum for mobile broadband.  As evidence of the need, it says that, compared to feature phones, smartphones use 24 times the spectrum and tablets 120 times the spectrum.

Reports from NAB and CTIA Address Efficient Use of Spectrum

Recent contributions to the mobile broadband spectrum debate are reports from NAB and CTIA. I envisioned a “dueling reports” piece, but they mostly complement each other. Below I walk through the main points, adding some of my own views.

Experimental Radio Applications at the FCC

This summarizes a selection of applications for the Experimental Radio Service received by the FCC during January 2011. These are related to land mobile radio, VHF propagation study, satellite communications, network-centric warfare, TV white space, software defined radio (SDR), military command and control, remotely piloted aircraft, LTE, radio direction finding, OpenBTS, Identification Friend or Foe (IFF), peer-to-peer communications, flight test telemetry, automotive telemetry, WiMAX, surveillance radar, vehicle radar systems, and millimeter-wave communications.

FCC Takes Further Steps toward Mobile Broadband in TV Spectrum

On November 30, the FCC adopted a Notice of Proposed Rulemaking (NPRM) as a preliminary step toward making the current TV broadcast spectrum available for use by fixed and mobile wireless broadband services. The proposed rules would do three things: 1) make fixed and mobile wireless services co-primary with broadcasting in the FCC’s Table of Frequency Allocations, 2) create a regulatory structure giving two or more TV stations the option to share one 6 MHz channel, and 3) improve VHF TV reception through power increases and adoption of receiver antenna standards. No service rules are being proposed; they’re to come later. Congress has yet to approve incentive auction authority.

The FCC’s Spectrum Deficit Estimate

The FCC’s National Broadband Plan (NBP) recommends that the Commission make available 500 MHz of new spectrum for wireless broadband, including 300 MHz for mobile use. In support of that recommendation, on October 21, the FCC released an FCC Omnibus Broadband Initiative technical paper: Mobile Broadband: The Benefits of Additional Spectrum. The paper concludes that mobile data demand is likely to exceed capacity in the near term and, in particular, that the spectrum deficit is likely to approach 300 MHz by 2014.
