Adaptive data rates for push-to-talk transmissions

Abstract

Examples described herein provide adaptive data rates for push-to-talk transmissions. One example provides a fixed network device that communicates with push-to-talk portable electronic devices via a communication network. The fixed network device comprises an electronic processor configured to, for each push-to-talk transmission of the portable electronic devices, receive a push-to-talk transmission request from a first portable electronic device, determine a set of the portable electronic devices within a talkgroup participating in the requested push-to-talk transmission, determine, based on a characteristic of the talkgroup, a vocoder data rate and a forward error correction coding data rate for the requested push-to-talk transmission, and transmit the determined vocoder data rate and the determined forward error correction coding data rate to the set of portable electronic devices within the talkgroup.
