IEEE 802 and 3GPP are working together more on coexistence of Licensed Authorized Access (LAA) and Wi-Fi. Since November, each group has made a presentation to the other. There’s been an exchange of liaison statements, the latest on March 18 when IEEE 802 sent 3GPP two statements containing several requests and recommendations.

IEEE 802 and 3GPP step up collaboration on LAA
Monday, March 23rd, 2015Experimental Radio Applications at the FCC
Sunday, November 6th, 2011This summarizes a selection from 173 applications for the Experimental Radio Service received by the FCC during August and September 2011. These are related to long-range low-frequency radar, amateur radio, shortwave data, wireless microphones, single-sideband, mine detection, millimeter-wave communications, signal intelligence, automotive radar, satellite feeder links, meteor-burst communications, aircraft telemetry, white space systems, border security radar, 3G and 4G applications, RFID, wind turbine testing, unmanned aerial vehicles, spacecraft telemetry and control, aircraft passenger broadband, and autonomous aircraft landing systems. The descriptions are sorted by the lowest frequency found in the application.
Experimental Radio Applications at the FCC
Monday, June 13th, 2011This summarizes a selection of applications for the Experimental Radio Service received by the FCC during April and May 2011. These are related to TV white space, electromagnetic compatibility testing, train control, point-to-multipoint communications, satellite communications, radar, unmanned aerial vehicles, GPS, ultra-wideband, mobile satellite service, UMTS, mobile broadband picocells, wireless backhaul, and IEEE 802.11p. The descriptions are sorted by frequency.
Stanford-developed Transceiver Operates Full Duplex on a Single Channel
Wednesday, March 2nd, 2011To 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.
ITU Gets “4G” Pushback from IEEE 802
Saturday, November 27th, 2010The IEEE 802 Executive Committee today approved correspondence asking ITU for clarification on its use of the term “4G” in an October 21 press release on IMT-Advanced. The main concern is ITU’s characterization of IMT-Advanced as “true 4G.” IEEE 802 observes that some in industry and government use 4G to mean mobile broadband technologies other than IMT-Advanced. Consequently, IEEE 802 says, ITU’s announcement has caused such users to be on the receiving end of “public response” (i.e., negative publicity), and could cause “significant disruption” to existing technical activities and documentation. It also observes that such use of 4G seems inconsistent with ITU-R Working Party 5D’s prior consideration of the term.
