What is Push-to-Talk over Cellular (PoC)?

Push-to-talk technology has been around for decades, originally popularized by two-way radios used in military and public safety. PoC takes this concept further by utilizing cellular networks and the internet to enable instant voice communication over vast distances. This innovation eliminates the range limitations of traditional systems, making it possible for teams to communicate without geographic constraints.

Push-to-Talk over Cellular (PoC) is revolutionizing how we communicate by integrating traditional push-to-talk functionalities with modern cellular and internet technologies. This blend of old and new is vital for various sectors needing reliable and efficient communication solutions.

How Push-to-Talk over Cellular (PoC) Works

PoC operates by converting voice messages into data packets transmitted over cellular networks or Wi-Fi. Users press a button to send a voice message, which is then instantly delivered to other devices in the network. This system includes several components:

• PoC-enabled Devices: Smartphones or specialized radios.
• Cellular Network Infrastructure: Utilizes 4G/5G networks for wide coverage.
• Software Platforms: Manage communication channels and user permissions.

PoC radios can seamlessly integrate with 4G and 5G networks, offering high-speed data transmission and low latency for instant communication. Additionally, they can operate on UHF and VHF frequency bands, which are ideal for different communication requirements:

• UHF: Suitable for urban environments due to better penetration through buildings.
• VHF: Ideal for open areas with longer range but less penetration capability.
