The Federal Communications Commission (FCC) has released a study completed last month by its Office of Engineering and Technology. One of the ongoing goals of FCC policy has been to expand broadband access to more citizens—especially in impoverished or rural areas. Any auction of this particular band would be conducted with the proviso that the winning bidder would be obligated to provide such free wireless service. Wireless telecoms incumbent in adjacent bands, especially T-Mobile, have expressed concern that allowing the introduction of advanced wireless devices providing such broadband access would cause interference to their customers’ wireless devices. Nonetheless, the Public Notice and the Test Results and Analysis just released indicate that a deployment of Time Domain Duplexing technology operating in close proximity to a Frequency Divisioned network “does not necessarily result in interference.” Predictably, broadband advocates have welcomed this development while T-Mobile has accused testers of basing their conclusions on changed assumptions. Those who like to judge for themselves can view both the notice and the test results online.The proliferation of wireless devices always raises the specter of increased interference.
