A Boston-based firm founded by a group of scientists is building a system that will help operators, government entities and others navigate the tricky world of spectrum sharing in the 3.5 GHz spectrum band, or Citizens Broadband Radio Service (CBRS). The FCC has said it intends to apply spectrum sharing to the 3550-3650 MHz spectrum band and is considering extending that service to the 3700 MHz, which would provide a total of 150 MHz of spectrum to CBRS.
Commenters applauded a federal government proposal to set up a public-private partnership that would create a model city for testing spectrum-sharing policies and technologies.The plan was floated in July by the FCC and the National Telecommunications and Information Administration (NTIA).
The FCC has a lot of work ahead if it hopes to create consensus around its plans for a Citizens Broadband Radio Service (CBRS) at 3.5 GHz, as specific parts of its proposed rulemaking have come under attack from multiple corners.
Verizon is joining chipmaker Qualcomm and infrastructure vendor Ericsson on field trials of spectrum-sharing technology in the 3550-3650 MHz band at multiple locations.
The FCC and the National Telecommunications and Information Administration (NTIA) are jointly soliciting comments regarding plans to set up a public-private partnership aimed at creating an urban test city where dynamic spectrum sharing could be demonstrated and evaluated.
One of the keys to enabling the FCC's plan for spectrum sharing in the new 3.5 GHz Citizens Broadband Radio Service (CBRS) is the spectrum database, which will dynamically manage spectrum allocations on the fly, based on preset policies and spectrum availability to protect against interference that might negatively impact incumbents and priority users.
Wireless industry players are finding a number of problems with the FCC's proposed plan to open up the 3.5 GHz band for a Citizens Broadband Radio Service (CBRS), which would enable spectrum sharing among federal and non-federal incumbents, holders of priority access licenses (PALs) and unlicensed general authorized access (GAA) users.
WASHINGTON—CTIA President Meredith Attwell Baker wants to create a spectrum "report card" that would assess how efficiently government agencies are using their spectrum. That's one piece of a broader agenda she has for getting more airwaves for mobile broadband use beyond this fall's coming auction of AWS-3 spectrum and next year's incentive auction of 600 MHz broadcast TV spectrum.
The National Telecommunications and Information Administration (NTIA) pledged in a blog post to continue engaging federal and industry stakeholders to ensure a smooth transition of the 1695-1710 MHz and 1755-1780 MHz AWS-3 bands. The agency also said it will also work with these stakeholders and the FCC to develop "sharing options to accommodate new and innovative broadband applications and devices in the 3.5 GHz and 5 GHz bands."
Mimosa Networks' petition asking the FCC to open the 10 GHz band for shared and lightly licensed use drew numerous negative comments from the amateur radio community, which along with federal and non-federal radiolocation services, constitute the band's current users. Brian Hinman, Mimosa's founder and CEO, acknowledged as much in a recent blog post.
