PTT Radio Questions
How far can a cellular PTT radio reach?+
Anywhere with 4G, 5G or Wi-Fi coverage. Range is set by the mobile network, not by repeaters or terrain, so a team in Johannesburg can talk to a colleague in Cape Town.
What happens when there is no cellular signal?+
Cellular radios need a mobile or Wi-Fi connection. For sites without signal, we connect traditional radios through a radio bridge so both work together.
Can cellular radios talk to our existing radios?+
Yes. A radio bridge connects your current radio network, so traditional and cellular users talk on the same groups.
Can I rent radios instead of buying them?+
Yes. Radios come as a rental package from R185 ex VAT per device, per month, with the device, SIM and software included.
