A system for exchanging information across networks that are incompatible and use different protocols.

Basically, a gateway is a combination of hardware and software that connects two different types of networks so that information can be exchanged. The hardware devices (called bridges) and the computer programs perform the necessary translations.

A "mobile gateway" on the other hand, is a ground-based link to a mobile satellite service network.
