At the heart of the Defense Advanced Research Projects Agency's (DARPA) newest challenge is finding ways to optimize the use of wireless spectrum in ways not possible with today's approaches – and the challenge is now officially on.
As the FCC is poised to vote on Chairman Tom Wheeler's Spectrum Frontiers proposal on Thursday, CTIA blasted a number of claims coming from the satellite industry and reminded commissioners just how many times satellite companies have tried to launch operations in the past and epically failed.
CTIA is urging the FCC to get a move on when it comes to the high-band millimeter wave spectrum and not pay attention to arguments that Boeing and the Satellite Industry Association (SIA) have put forth regarding more time for establishing sharing parameters between satellite and terrestrial mobile operations.
CTIA said it wants to be a database administrator for the new Citizens Broadband Radio Service (CBRS) in the 3.5 GHz band, despite the association's concerns about how the FCC's new rules around the band might interfere with licensed operations in nearby bands.
While everyone pretty much agrees that releasing more spectrum is good, the experimental nature the FCC is taking with the 3.5 GHz band isn't making all wireless carriers jump with joy. In fact, CTIA says the FCC failed to put into place appropriate incentives and protections for licensed users and risks undermining the success of its spectrum sharing model.
The FCC today reaffirmed its decision to create the Citizens Broadband Radio Service (CBRS) in the 3.5 GHz band and took steps to finalize the rules for a new experimental sharing regime, making 150 MHz available for mobile broadband and other commercial uses.
While AT&T and EchoStar agreed to a potential sharing framework for the 28 GHz band, other stakeholders in the satellite industry and AT&T rival Verizon are still working on complicated technical details to make sharing possible.
Reacting to a proposal for sharing in the 28 GHz and 37/39 GHz bands as outlined by AT&T and EchoStar, Boeing says its proposal represents only a single viewpoint and should not be taken to represent a consensus within the satellite industry.
Ofcom published a new framework that it will apply to future decisions on spectrum sharing, and also said it is considering the 3.8-4.2 GHz band as the first opportunity under the structure for shared access.
AT&T and EchoStar executives presented their potential framework for sharing the 28 GHz band and the 37.0-40.0 band to the FCC, saying they believe it achieves three primary goals.
