Advocates of sharing in the citizens broadband radio service (CBRS) and 6 GHz bands remain concerned that parts of those bands could be reallocated for full-power licensed use, but decisions probably won’t be made for some time, Disruptive Analysis consultant Dean Bubley said Tuesday during a Broadband Breakfast webinar. Bubley and Dave Wright, policy director for Spectrum for the Future, said CBRS offers unique capabilities that many users want and that help the U.S. compete with China.
The FCC on Monday approved Nokia as a spectrum access system administrator in the citizens broadband radio service band for a five-year term. The order also approved Nokia to support spectrum manager leasing for priority access licenses.
WISPA filed a letter at the FCC on Monday asking the agency not to move the citizens broadband radio service (CBRS) operations to another band or otherwise make major changes to the rules (see 2512050029). In other comments posted Monday in docket 17-258, wireless ISPs said they may be forced to shut down if the rules are changed.
Wireless ISPs continue to urge the FCC not to relocate citizens broadband radio service operations from any portion of the 3.55-3.70 GHz band to another band. CBRS advocates have been pushing against any major change to the band. NCTA is encouraging service providers to file comments at the FCC opposing proposals to increase power levels (see 2511130037).
The FCC should retain its current citizens broadband radio service (CBRS) rules, said Cambium Networks in a letter posted in docket 17-258 Monday. “Increases to permitted power in some or all of the band would undermine deployments that are providing vital services to American communities.” Reallocating portions of the CBRS band or increasing the maximum power would require Cambium to replace its equipment “at significant operator and consumer expense,” the company said. “Further, permitting significantly higher power levels would lead to waste in [the] BEAD program, as existing CBRS equipment supporting fixed wireless BEAD deployments would need to be replaced and such costs have not been included in BEAD,” Cambium added. “It is inconsistent for the federal government to make billions of dollars available for broadband deployment and expect recipients to invest their own capital, at the same time that it calls into question the usefulness of the most relied-upon spectrum for broadband deployment.”
Wireless ISPs continued to weigh in at the FCC last week to oppose major changes to rules for the citizens broadband radio service band (see 2512010052). Questions remain about the future of the band, with some wireless carriers looking at the spectrum for full-powered licensed use, and others urging higher power levels for some operations (see 2511260031).
NCTA opposed a waiver request from Brownsville, Texas, asking to operate a city network that uses the citizens broadband radio service band at +60 dBm effective isotropic radiated power, which is higher than the +47 dBm allowed by FCC rules (see 2511250015). The group is concerned that approving the waiver “would increase the risk of interference with other CBRS operations, undermining the carefully calibrated framework that is vital to the band’s success,” said a filing posted Tuesday in docket 17-258.
New Era Broadband, a wireless ISP in Ohio, opposed any move to relocate the citizens broadband radio service band or raise power levels (see 2511260031). Moving the band would “basically put us out of business,” said a filing posted Monday in docket 17-258. “Drastically changing the CBRS rules could cost our business, which would directly impact 7 jobs, nearly 800 internet users, multiple first responders, firehouses, township operations.”
The outlook for the citizens broadband radio service band appears uncertain, with some wireless carriers looking at the spectrum for full-powered licensed use and CBRS advocates defending it as an important band for sharing and unlicensed use. FCC Chairman Brendan Carr has had little to say about CBRS since he took over the helm at the commission.
Brownsville, Texas, is seeking a waiver from the FCC to operate a city network that uses the citizens broadband radio service band at +60 dBm effective isotropic radiated power, which is higher than the +47 dBm allowed by agency rules. In a filing posted Monday, the city emphasized that it’s located on the Mexican border and uses the network for border security. The higher power levels would mean the city needs about a third as many nodes to operate the network, it said. “The City’s planned outdoor applications -- spanning public safety, border security, and critical infrastructure operations -- require broader signal reach and fewer network nodes than the existing limits allow.”
