Broadband mapping in the United States are efforts to describe geographically how Internet access service from telephone and cable TV companies (commonly called "broadband") is available in terms of available speed and price. Mapping has been done on the national as well as the state level. The efforts are seen as preliminary steps towards broadband universal service.
Internet access and bit rates (often called "speeds") vary considerably across the US. Generally, rural Internet users have fewer options and slower service. American consumers often spend more money for slower service than in other countries.
Former Federal Communications Commission (FCC) and California Public Utilities Commission commissioner Rachelle Chong floated the idea of broadband mapping while working for the Governor Arnold Schwarzenegger Administration in California in 2006. The California Broadband Task Force had performed the first voluntary broadband mapping exercise in that state in 2006-2007, having learned about it when Commissioner Chong visited the ConnectKentucky broadband project in 2005. The broadband maps were then used by the CPUC to determine both "unserved areas" (defined as an area that is not served by any form of facilities-based broadband, or where Internet connectivity is available only through dial-up service or satellite) and "underserved" areas (defined as an area in which broadband is available but no facilities-based provider offers service at speeds of at least 3 megabytes per second (MB/s) download and 1 Mbit/s upload). A $100 million program called the California Advanced Services Fund (CASF) was established on December 20, 2007, under the leadership of Assigned Commissioner Chong at the CPUC to bring an "onramp to the Internet" to unserved areas and underserved areas of the state, with unserved areas having first priority using filing windows. In 2008, State Senator Alex Padilla (D-Pacoima)codified the CASF program with Senate Bill (SB) 1193, signed by Governor Schwarzenegger on September 29, 2008, to ensure it had the legislative authority it needed to operate. On September 25, 2010, Governor Schwarzenegger signed SB1040 which added CASF funds of $125 million, of which $100 million went to broadband infrastructure funding, and $25 million to broadband adoption programs.
