Recent federal government efforts to expand use of public Citizens Broadband Radio Service (CBRS) spectrum could be of significant help to municipalities and local communities looking to bridge the digital divide with the increasingly popular wireless technology.

CBRS spectrum refers to 150 MHz of spectrum in the 3.5 GHz band. In 2015, the FCC adopted rules for shared commercial use of the band, creating a three-tiered structure to avoid interference with military radar during collaborative use of the spectrum.

For municipalities, the spectrum has already proven to be a valuable way to deploy wireless access to the public. In Syracuse, New York, the city last fall launched a new public wireless network on the back of CRBS. In Longmont, Colorado, the St. Vrain Valley School District used CBRS to build a private LTE network connecting 4,000 students in partnership with NextLight, which operates Longmont's city-owned municipal fiber network.

Not all community deployments of CRBS have delivered satisfactory results for municipalities, however. The STEM Alliance in Westchester County, New York retired their efforts to deploy a CBRS network in Yonkers after they struggled with urban capacity constraints and low usage.

When a $25 million broadband funding award for the Colorado River Indian Tribe (CRIT) was announced in July 2023, CRIT Chairwoman Amelia Flores celebrated it as a “game changer.”

“Broadband access is essential,” Flores’s statement read, making “remote learning, telecommuting, conducting business, and simplifying staying connected” possible.

Coming amid a rolling series of announcements from the Tribal Broadband Connectivity Program – each lauding millions of dollars in broadband funding for Tribes – it would have been easy to file away CRIT’s award as another from that pathbreaking broadband funding program for Tribes.

But this was not the TBCP. Rather, CRIT was among a handful of Tribes that received substantial funding awards from another federal source that has recently stepped up their grantmaking to Tribes – the U.S. Department of Agriculture’s (USDA) ReConnect Grant Program, administered by the department’s Rural Utilities Service (RUS).

CRIT’s award is a helpful reminder that TBCP is not the be-all-end-all of funding for Tribal broadband. With an award cycle now open, ReConnect offers powerful tools and incentives –  including dedicated Tribal funding, 100 percent grants, and consent for any new infrastructure on sovereign lands – for Tribes looking to expand or launch broadband service.
