What is Push to Talk over Cellular?

The concept of Push-to-Talk over Cellular (PoC) was introduced by Nextel in 1987 as an alternative to two-way radios. Push to talk over cellular; as the name suggests, is an emerging technology that combines the well-known “Push to talk” capability commonly used in two way radios with 4G cellular coverage. Due to utilising 4G the devices have very wide coverage being able to communicate with any device that has 4G coverage.

Today, Push-to-Talk over Cellular uses the modern LTE cellular infrastructure of Mobile Network Operators to provide nationwide coverage with unlimited voice and video call groups.

Expand your communication, create your own network

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 LTE cellular networks provides the bandwidth required for modern data, photo, and video applications, along with nationwide LTE coverage. Some other key advantages are listed below:

• No infrastructure costs – compared with traditional wide area systems which have very expensive set-up costs.

• Versatile Contracts – You can easily manage data, with no lengthy contracts to sign up to.

• Compatible with Multiple devices – SFL’s PTTOC platform works on a wide range of devices that we supply. It is also compatible with Android and ios devices and we can supply a licence only package if you would like to use your own device.

• Features – PTTOC devices have the ability to support a wide range of features including man down and lone worker.

• Flexible payments – The devices are available both for hire and purchase and packages can be tailored to meet your requirements.

Here are the connectors we are dealing with POC radios so far.
