As reported in PC World, the FCC will soon move forward on a 2-year-old proposal to experiment with spectrum sharing. This is in response to skyrocketing demand for mobile data bandwidth and increasingly crowded mobile services. The remarks were made on Monday by FCC Chairman Tom Wheeler.
The FCC plans to implement spectrum-sharing recommendations made by the President’s Council of Advisors on Science and Technology (PCAST) Report that was issued in 2012.
The FCC Chairman was quoted as saying, "Spectrum-sharing technologies, along with an upcoming two-sided auction of spectrum now controlled by U.S. television stations, hold the promise to completely revolutionize the way we manage our airwaves.”
The PCAST report called on the U.S. government to share its spectrum in the 3.5GHz band now used by radar systems. Radar systems could share the spectrum with other wireless services using small cells, the report said.
xG Technology's xMax is a comprehensive fixed and mobile broadband solution that leverages software defined radio (SDR) and cognitive radio access network technology that enable efficient sharing of both licensed and unlicensed spectrum.
xMax is designed to ‘see through’ the spectrum clutter, mitigate interference encountered, and allow optimal spectrum use. xMax increases the efficiency of existing spectrum, allowing the delivery of new services, offload of existing voice or data traffic, improved QoS, and enhancement of network capacity for users in a wide array of customers.
In the upcoming FCC proposal, the 3.5MHz band would be designated an “innovation band,” as outlined in the PCAST report, Wheeler said. His proposal would allow for three tiers of priority access to the shared spectrum, with government agencies and licensed users getting the highest priority. But there would also be room for “general authorized use” of the shared spectrum, he said.
Demand for spectrum will only increase in the future. According to Cisco, global mobile data traffic will increase nearly 11-fold between 2013 and 2018, growing at a compound annual growth rate (CAGR) of 61 percent.
The FCC is expected to run out of 5MHz pieces of spectrum to carve out for specific uses, according to Preston Marshall, a wireless networking researcher at Google.
“How do we manage the sharing among uses?” said Marshall, who advised PCAST on the spectrum-sharing report. “We are running out of spectrum to give every different application its own. We have to make a transition to say, we allocate spectrum access, but we don’t allocate spectrum.”
