Abstract

This presentation explores a low-cost method to bridge analog public safety Land mobile radio (LMR) systems into a standards based Long Term Evolution (LTE) Mission Critical Push to Talk (MCPTT) system. Design goals include robustness, cost, and the creation of a system that closely conforms to released and future standards. A proof of concept prototype that successfully bridges an analog LMR system with a standards-compliant LTE based MCPTT system was developed and tested. The results and design details are covered in this presentation.
