Project 25 has a large established base of over 2800 systems on the air today offering Mission Critical PTT communications to Public Safety and government agencies nationwide. As the new First-Net Broadband data system rolls out; many radio users and technologists question what type of Mission Critical PTT interoperability and sharing will be available between the two systems. The TIA TR-8.8 subcommittee (responsible for development of P25 Standards for Broadband Data Systems) and The Alliance for Telecommunications Industry Solutions ATIS have an ongoing Working Group to develop guidelines for MCPTT inter-working between P25 and LTE systems. A study document is complete that contains scenarios and considerations for the use of a 3GPP Release 15 Interworking Function (IWF) to enable interoperability of common standard services between a 3GPP MC system (First Net)and a TIA-based LMR system (P25). Three distinct TIA-based LMR systems are examined: P25 trunking, P25 conventional, and TIA-603 analog conventional FM. Business Models of potential LMR/LTE Applications will be explored along with Public Safety User Expectations for PTT Operation and Interworking between the two services. An open Q&A period will be offered with the panel of experts.
