System components


We offer multiple ODM and OEM handsets from entry-level to IP65 and Android models.

Base stations

Offerings consist of both multi-cell and single cell solutions for small, medium and large installations requiring wireless mobility.


In places where coverage extension only is required, the repeaters from RTX do the job for both single-cell and multi-cell deployments.


When people need to have their hands free for other stuff, the multi-cell headset is a perfect partner, as it allows easy access to calls while being able to use both hands.
