Broadband Federal Funding

Rural Digital Opportunity Fund

The Federal Communications Commission (FCC) established the Rural Digital Opportunity Fund (RDOF) to award up to $20.4 billion to support broadband services for eligible areas across the nation. The FCC will award funding in two phases using a reverse auction process. Phase I is currently underway with a $16 billion budget, and the Phase I Auction 904 will begin on October 29, 2020. Additional information on Auction 904 is provided below. 

The CPUC encourages all eligible carriers to apply for federal funding to help close the digital divide in California. See the California RDOF Eligibility Map for eligible census blocks in California based on the FCC's June 25, 2020 updated eligible areas.

Anti-Collusion Requirements

The FCC prohibits certain communications by auction applicants: 

146. To help protect competition in the auction, the Commission’s rules prohibit an applicant from communicating certain auction-related information to another applicant from the auction short-form application filing deadline until the post-auction deadline for winning bidders to file long-form applications for support. More specifically, section 1.21002 of the Commission’s rules prohibits an applicant in Auction 904 from cooperating or collaborating with any other applicant with respect to its own, or one another’s, or any other competing applicant’s bids or bidding strategies, and from communicating with any other applicant in any manner the substance of its own, or one another’s, or any other competing applicant’s bids or bidding strategies during the prohibition period. The rule’s exception for communications between applicants that are members of a joint bidding arrangement shall not apply in Auction 904.

See Auction 904 Procedures and Requirements, Section G "Prohibited Communications and Compliance with Antitrust Laws" for all FCC rules.
