BEAM; amend definitions for "applicant" and "eligible project" and add "retail end user."

SB 2783 amends Mississippi's broadband grant program definitions to distinguish between projects serving retail end users (homes/businesses) and other projects. It redefines "applicant" to require retail-focused applicants to be qualified broadband providers with state authorization and proven resources, while other applicants only need standard grant eligibility. The bill also clarifies "eligible project" for retail projects as discrete initiatives in unserved areas, and updates "broadband service" to require minimum speeds (100 Mbps down/20 Mbps up). These changes directly affect entities applying for state broadband grants under the BEAM program, ensuring clearer eligibility criteria for funding.
