Push-to-Talk over Cellular (PoC)
Instant Communication with Nation-wide Coverage.
How Push-to-Talk over Cellular (PoC) Works?
PoC devices connect to the cellular infrastructure networks of Mobile Network Operators, using a SIM card identical to those installed in cell phones. PoC network services are hosted in the Cloud. The Cloud services are located on privately hosted servers owned and operated by the PoC platform. Gateway routers provide connectivity between the Mobile Network Operator networks and the PoC servers. The advantage is a highly reliable network that requires no network infrastructure investment and maintenance. An app on the radio (typically an Android operating system) provides simple and convenient access to PoC services.
PoC Radios also support WLAN connectivity. The WLAN capability enables calls inside buildings with WLAN network coverage that fill gaps where an LTE network has limited connectivity. PoC radios automatically and seamlessly switch to an LTE network when a caller moves outside WLAN network range.
Advantages Over Legacy PMR Technology
Issues with legacy PMR tech such as DMR, TETRA amd P25 inlcude the fact that they are lmited to voice service only and have poor data service capabilities. They also do NOT support video or have data applications. These mediums have high costs on wide coverage and require dedicated infrastructure.
Push-to-talk over Cellular gives you the nation wide coverage of public network operators. We provide specially designed handsets that give instant PTT communication and the same user experience as legacy PMR radios. Futhermore these handsets integrate video service and business applications on the same device all without the need of any network infrastructure.
PoC makes spectrum management for the Regulator very easy and more efficient while saving costs for the end user as they do not have to pay any Spectrum fees.
