CBRS Band Moves Another Step Closer to Launch

The FCC tentatively approved the first environmental sensing capability (ESC) operators for the 3.5 GHz citizens broadband radio service band, moving launch of the CBRS sharing band another step closer to reality. The ESC operators allow sharing in coastal areas, protecting Navy radars. The four are: CommScope, Federated Wireless, Google and Key Bridge Wireless. All must now submit their systems for testing before final certification, the FCC said. “The ESC operators will manage a sensor system designed to detect the presence of federal incumbent radar transmissions in the 3550-3650 MHz portion of the 3.5 GHz Band and communicate that information to one or more Spectrum Access Systems (SAS) in accordance with the Commission’s rules,” said the notice by the Office of Engineering and Technology and the Wireless Bureau. “The ESC will enable more dynamic sharing between federal and non-federal users in the band, particularly in coastal areas.” Commissioner Mike O’Rielly last week said approval of the operators was imminent (see 1802130041). “Today’s important step gets us closer to permitting 3.5 GHz use in coastal areas where a huge population of Americans live and attracting necessary investment for equipment manufacturing and network deployment," O’Rielly said Wednesday. Ruckus Networks Wednesday announced release of 3.5 GHz LTE access points and associated cloud-based subscription services. The 3.5 GHz market is likely to be huge, Ruckus said. “The Ruckus LTE portfolio enables enterprises to deploy private LTE networks to ensure high quality-of-service (QoS) for critical business applications,” said a news release.
