FCC Broadband Map

The FCC Broadband Map displays where Internet services are available across the United States, as reported by Internet Service Providers (ISPs) to the FCC. The map will be updated continuously to improve its accuracy through a combination of FCC verification efforts, new data from Internet providers, updates to the location data, and—importantly—information from the public.

CPUC Federal Funding Account Map

The CPUC Federal Funding Account Map allows you to view and explore locations in California that are unserved by broadband Internet service within the Census Blocks and are eligible for funding under the Federal Funding Account program. You can also provide feedback related to broadband availability in each Census Block or unserved location.  This map is available to the public.  The CPUC FFA Application Tool requires a license and credentials, and is part of the FFA grant application process.

California Interactive Broadband Map

The California Interactive Broadband Map shows eligibility by location for the California Advanced Services Fund (CASF) Infrastructure Account grant program.

Planned Middle-Mile Broadband Initiative Map

The CPUC Anchor Build Fiber Highways map depicts the statewide middle-mile network that was proposed to span the entire state. The initial map was presented at the May 20 Middle-Mile Advisory Committee meeting and delivered to Caltrans to conduct preconstruction work.  The current iteration of the planned 10,000-mile network is shown in the Middle-Mile Broadband Initiative Project Map that was updated on September 15, 2023.

You can enable different layers to show which parts of the project will be constructed, leased or purchased.  Details on the timelines for completion of specific sections are not yet specified.

NTIA Permitting and Environmental Information

The NTIA Permitting and Environmental Information Application (map) shows Federal and State land ownership, as well as Historic locations, Critical Habitat, and more.  This map tool is hosted by the National Broadband Availability Map GIS system.

FCC Research Maps

The FCC makes several different GIS research maps available to show a present visualizations of a variety of services.

Map of broadband-related assets in Mono and Inyo Counties

The interactive map below depicts broadband-related assets and locations in our region that may be of interest to providers for broadband deployment projects.  The layers used in the map below are publicly available in ArcGIS Online.  You can show or hide layers and layer information by clicking on the Layer icon in the black bar on the left side of the map (computer view) or the list icon on the right side of the map (mobile device view) and clicking on the eye icon.

The Eastern Sierra region enjoys an existing middle-mile network that runs generally along US-395 with a spur along US-6 from Bishop to Benton. The network was the result of the Digital 395 middle-mile broadband project funded by NTIA and the CPUC. The Digital 395 network is owned and managed by the California Broadband Cooperative. The network consists of 432 strands of fiber between Reno, Nevada and Barstow, California, with 11 signal regeneration nodes. Vaults providing access to the middle-mile fiber are located approximately every 4500 feet.

The Digital 395 middle-mile network connects more than 250 community anchor institutions, provides middle-mile services for Internet Service Providers and Cellular Service Providers, and provides both lit services and dark fiber options for a variety of customers in the region.

Other communications information:

  • Last-mile Internet Service Providers in our region include Frontier Communications, Optimum, Lone Pine Communications, Race Communications, Schat Communications, Fox Industries, Mono Broadband, and Hartstrom Wireless. Cellular service providers include AT&T, Verizon Wireless and T-Mobile.
  • Radio communications for a wide range of organizations are supported by mountain peak relay stations throughout the region.
  • Electrical power in the region is supplied by Souther California Edison and LADWP.

Some layers in the Layers list may appear grayed out.  Some of the layers are configured with Visibility ranges to make them visible only within a specified zoom range.  When a layer is out of range, its name appears in a lighter gray color in the contents and legend than the layers that are in range, and the layer will not display on the map.  When a layer is within the specified range, it will appear as normal text and the layer will display on the map.
