Connect Illinois has a current, detailed map of broadband availability in the state.
Illinois Commerce Commission
Broadband availability, cost and speed data is critical for policymakers, investors and technologists in Illinois.
Click the images above to enlarge and download maps that include the latest broadband data collected by the Illinois Commerce Commission.
To produce these maps, providers reported availability of service by either zip code or exchange (their choice), so the maps do not reveal instances where part of a zip code or exchange is not served.
However, they do reflect areas with access only to satellite or non-traditional (e.g. wireless) Internet services.
