Push to Talk – PTT GSM Radios
What is Push to Talk?
Push to Talk (PTT) is a means of achieving two way communications by utilizing a cellular device on existing GSM cellular network infrastructure. The service could therefore be offered where the GSM networks have coverage, which greatly reduces the limitations on geographical coverage offered by other two way communication systems. It is a technology ideally suited for organisations with the need to communicate cost-effectively with their personnel in the field or on the road.
