Hytera Push-to-Talk over Cellular

Push-to-Talk over Cellular (PoC) provides group communication services over 4G and Long Term Evolution (LTE) technology, creating a nationwide radio network that utilizes the cellular infrastructure of Mobile Network Operators. This enables radio networks with very wide coverage areas. Radio users are untethered by the range of repeaters and base stations used in traditional radio networks. The concept of Push-to-Talk over Cellular was introduced by Nextel in 1987 as an alternative to two-way radios. Nextel revolutionized business communication when it started to pass small voice packets across their iDEN network. Prior to PoC, business communication was dominated by two-way radios on peer-to-peer and local radio networks. Nextel was acquired by Sprint, and in 2013 Sprint decommissioned the Nextel iDEN network.

Today, PoC provides the best of both narrowband digital radios and broadband 4G/LTE networks. PoC radios support the advanced features of Digital Mobile Radios (DMR), including messaging, instant group calling, GPS location tracking, and emergency notifications. Combining this functionality with Wi-Fi and 4G/LTE cellular networks provides the the national coverage area and bandwidth required for modern data and video applications. Any business or organization that needs reliable and cost-effective group communications can deploy PoC radios quickly and easily without the infrastructure required for traditional radio systems.
