Rural Digital Opportunity Fund

RDOF Winning Bids

The Federal Communications Commission (FCC) established the Rural Digital Opportunity Fund (RDOF) to award up to $20.4 billion for support of broadband infrastructure deployment and network operations over a 10-year period. Funds are awarded for eligible areas around the country that lack broadband service of at least 25 Mbps down and 3 Mbps up (25/3). The FCC is using a reverse auction process for two phases of funding. Phase I (Auction 904) opened on 10/29/20 and closed on 11/25/20.

The California RDOF Map shows the winning bidders, with their areas, funding levels, and bandwidth tiers across the state.  Nationwide, while the FCC planned to issue $16 billion in this first Phase, in fact it announced auction results totaling $9.2 billion nationally on 12/07/20. In California, the state's assigned total reserve price was $2.049 billion for 370,986 locations and bidders won $695 million (34% of statewide reserve price) for 364,878 locations.  

RDOF Next Steps

The winning bids announced by FCC are results of Auction 904 and require further authorization before the disbursement of funds. The FCC requires winning bidders to meet all conditions and review criteria of the Long Form (Form 683) filing and certification process. Winning bidders are required to disclose detailed financial, operational, ownership, and technical information for review by FCC staff in the two-phase long-form cycle.

The balance of Phase I funds, together with the budgeted Phase II fund ($11.2 billion total) will be issued by RDOF Phase II.

CPUC and Comments to the FCC

Beginning in June of 2020, the California Public Utilities Commission (CPUC) worked to encourage all eligible carriers and providers to apply for RDOF funding to help close the digital divide in California. The Commission's comment and Ex Parte filings are filed in the FCC's RDOF docket.

CPUC: Recent Updates and Information

The CPUC's RDOF Kicker program provides financial incentive for RDOF bidders to bid on California areas in Phase I. The rules of the Commission's Kicker program are part of the CPUC's Rulemaking 20-08-021. Specific Kicker regulations are being finalized in a Proposed Decision entitled Establishing Process For The California Advanced Services Fund To Leverage The Federal Rural Digital Opportunity Fund.

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.
