Mobitex base stations
The basic functionality for a Mobitex network is provided by a number of radio base stations and one or more switches. Each base station, no larger than a briefcase, services a single radio cell, which typically has a diameter of 20 to 30 kilometers, depending on environment and other conditions. Together the base stations provide an area of coverage and determine the capacity of the network. Wireless devices communicate with the nearest base station but are also able to roam freely between radio cells and from one base station to another as the user's location changes. The system operates on the 400, 800 and 900 MHz frequency bands.

Mobitex switches
A Mobitex network normally contains several switches, which are connected by a backbone network. The switch routes traffic to and from the base stations and provides connections between wireless devices and fixed hosts. But it also provide important gateways to other networks. In the standard network configuration, there is an X.25 port implemented directly in the local switch, but several other gateway options, including IP connectivity, are available.

Network control center
The entire network is supervised and managed from the Mobitex Network Control Center (NCC). The NCC handles all operations and maintenance tasks, including network configuration, alarm handling, subscriber administration and billing information. Individual base stations and other network components can be reconfigured from the NCC, thus minimizing the need for costly and time-consuming site visits. Depending on the size of the network and the required level of functionality, the NCC can be hosted on one or more computers. The NCC or management system is normally located at the company 's operations or dispatch center.
