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.

Stanford-developed Transceiver Operates Full Duplex on a Single Channel

To avoid interference, wireless transceivers can switch between transmit and receive on one frequency (Time Division Duplex (TDD)). Or, they can transmit and receive at the same time on different frequencies (Frequency Division Duplex (FDD)). There’s been a flurry of press reports about a new radio system, developed by Stanford researchers, that can operate full duplex on a single channel; that is, transmitting and receiving at the same time on the same frequency, something not done before.

FCC Seeks Input on Dynamic Spectrum Access

As a prelude to proposing rules, the FCC is seeking comment on many issues related to dynamic spectrum access technologies, including how they can increase spectrum capacity and what the Commission can do to promote their use.

“Trusted” Academia Favored over Industry in FCC’s Proposed Experimental Rules

With praise for academia, the FCC has adopted a Notice of Proposed Rulemaking (NPRM) that would make it easier for colleges, universities, and non-profit labs to conduct radio experiments. The proposed rules create a “program experimental radio license” that lets those institutions apply for broad, long-term, blanket licenses that reduce the need to go to the FCC for each and every experiment. Licensees would instead give seven days’ notice of new operations to the FCC and to the public via an FCC website. Potential interference victims could object before or after the experiment starts, but the burden of proof is on them. Licensees would agree to keep interfering signals on their property. Find something interesting during the experiment that makes you want to try a new frequency? Submit a new notice. It’s a streamlined process that will reduce licensing delays and speed up academic R&D. To get this efficiency, however, interference policing shifts from the FCC to potential interference victims; they’ll have to be on heightened alert.
