What is PoC (Push-to-Talk over Cellular)?
-
PoC enables instant, one-button group communication over existing cellular networks.
Push-to-Talk over Cellular (PoC) allows users to initiate real-time group calls and access command and dispatch services over 3G, 4G LTE, and WLAN networks.
By leveraging nationwide 3G and 4G infrastructure, PoC delivers wide-area coverage, seamless connectivity, and fast deployment—without the high cost of traditional radio systems. Its ease of use, scalability, and low startup investment have made PoC increasingly popular across a wide range of industries.
Why Choose PoC (Push-to-Talk over Cellular )?
-
· No Spectrum Licensing Required
PoC operates over existing cellular and WLAN networks, eliminating the need for dedicated radio spectrum investment.
