The modular architecture allows ANTRAX users to place SIM cards apart from GSM gateways and connect them via IP. This feature provides a huge advantage in terms of safety and removes limitations which could be applied to the topology of your GSM termination system.

It is important to mention that the module-based structure of our product is a part of anti-anti-fraud system, which allows you to reduce the load on every single base station, placing GSM gateways in different locations, without compromising the overall capacity of your GSM termination system.

Group association allows you to associate more than one SIM card to every individual GSM module in GSM modem. It increases the reliability of the system and ensures its smooth operation when one or more SIM cards fail for some reason. In case of fail, the system will automatically replace SIM cards from the SIM array, which was previously associated with this GSM module, saving system capacity that could be temporarily lost in different situation.
