Amitec's Mobile Communication Lab

A Comprehensive mobile communication solution designed using current state of the art technology and real time interface emulating practical and industrial scenario

Datasheet

Complete Lab Package

The Amitec MCL02 is intended for lab use and is ideal for colleges, universities, testing labs. It allows to replicate small 2.5G GSM (Voice + GPRS) cellular network and start making calls in less than an hour.
It allows you to connect a standard GSM mobile phone directly with VOIP networks as SIP endpoint to call PSTN landline or mobile phone on other networks in other locations using a software based GSM BTS .

The lab is complete with base transceiver station, multiband cellular phones, backhaul radio. Base station controller (BSC) functions and operations/maintenance (O&M) and network management system (NMS) functions for controlling the base stations with software provided for exceptional value and performance

 

 

Real-time Interface
