Senate Bill 651 aims to enhance the security of critical telecommunications infrastructure in Wisconsin by prohibiting telecommunications providers from acquiring or maintaining equipment manufactured by foreign adversaries, as defined by the U.S. Department of Commerce. The bill mandates that providers remove any existing equipment that falls under this category and requires them to certify their compliance with these regulations annually to the Public Service Commission (PSC). Additionally, providers must report the geographic coordinates and service coverage areas of any prohibited equipment, along with a plan for its replacement.

The PSC is tasked with creating a public map that details the locations of the prohibited equipment and the corresponding telecommunications service coverage areas. This map will be included in an annual report submitted to key state officials and legislative committees. The bill defines "foreign adversary" and "foreign principal" to clarify which entities are affected, ensuring that the legislation targets specific countries and organizations deemed a threat to national security.
