Background:

Background: 1. The Mississippi Wireless Communication Commission (WCC) is implementing a statewide survivable, reliable, interoperable wireless communication system known as the Mississippi Wireless Information Network (MSWIN). 2. The WCC adopted the P-25 Phase 2 TDMA narrow banding technology and will retro-fit existing equipment or install TDMA equipment upon availability, anticipated to be June 2012. 3. TDMA will increase the capacity for existing tower equipment two fold with minimal expense. 4. Multiple Vendors offer P-25 Phase 2 ready subscriber equipment as well as P-25 Phase 2 capable (up-gradable) subscriber units. Source: Mississippi Code Ann. 25-53-171(4) 5.3 Procedure: 1. New subscriber or other equipment purchased for operation on the MSWIN must be TDMA capable or equipped. 2. Users operating TDMA capable devices, on MSWIN, must upgrade the devices within 90 days of notification that MSWIN has initialized TDMA. 3. Users operating non-TDMA capable devices, on MSWIN, must contact the MSWIN Liaison and cooperate in the development of a migration or usage plan to minimize the capacity impact of the continued use of the non-TDMA devices on the MSWIN system. 4. Users operating non-TDMA capable devices, with MSWIN special event talk groups, for emergency or short term event interoperability, must contact the MSWIN Liaison and agree to specific use guidelines.
