GSM Gateways

Background

The uptake of cellular telephones has exceeded that of fixed line telephones worldwide. In most instances the charges for a call from a fixed telephone service to a cellular telephone service exceed the charges for a call from a cellular telephone service to a cellular telephone service (fixed-mobile calls are more expensive than mobile-mobile calls).

In the highly competitive cellular phone market the Mobile Network Operators (MNOs) have lowered rates to call from cellular telephones as an incentive to bring consumers to their networks. Some MNOs allow "free" or uncharged calls to others on the same network. It is also a common practice for the MNOs to offer "capped plans" enticing consumers to use mobile phones more and more.

Why does my company need a GSM Gateway?

A GSM gateway enables cheap mobile-mobile calls instead of expensive fixed-mobile calls. The gateway can e.g. be connected to a PBX system. So all calls into cellular networks will be routed via the gateway instead of via the PSTN (Public Switched Telephony Network). GSM gateways use integrated wireless modules (the same types of wireless modules are used in standard cellular phones) as well as integrated antennas.

The GSM gateway has been designed to route calls between a company’s telephone system and the mobile network directly --- by-passing their ISDN/PSTN fixed line services.

The GSM Gateway suits companies who experience high traffic call volumes to mobiles and who are on “Carrier” plans that suit. The gateway is scalable and provides powerful but easy to use software interface for operation.

E.g. a carrier may charge 20 cents for a fixed to mobile call. The same call charged at the mobile to mobile rate by the same carrier is 6 cents. The gateway builds the facility of accessing the carriers cheaper rates for mobile to mobile calls.
