The SAGEM Engineering mobile

2 and 2,5G capability

The SAGEM test tools are designed to fulfil the operators and integrators requirements and to provide the best solution to operate and maintain GSM and GPRS networks.

Real time network monitoring

SAGEM OT 200 range gives all trace information for investigation or quality monitoring. GSM/GPRS software provided with the mobile enables visualisation, recording and replay of all information.

Open interface for external trace processing and logging

The physical interface, based on standard serial interface, makes easier the use of the terminal in trace or transfer mode.

Trace storage

Capability to store in the mobile alone measuments made in real time. The datas are download in a computer using the data interface in trace mode.
