Overview of the Mobitex Network structure and function

For those who need instant wireless data communication throughout the day, the MDRS wireless data network is always on and instantly accessible. There are no time consuming call setup or data activation procedures, and never any busy signals. Response times are short and access is instantaneous. Because packet switching does not require a dedicated connection, users can remain online at all times, sending and receiving data as required by the application. Users can thus make maximum use of network resources.

Unlike circuit-switched networks that require dedicated connections, packet-data networks are connectionless. MDRS uses techniques to ensure that data packets are always delivered to the receiver, even if some part of the network is temporarily unavailable.

The MDRS also accommodates true push functionality. This means that a host application can initiate a transmission to a mobile device without a request from the device and that information can be pushed out to the device. This functionality is particularly useful in command-and-control functions and for telemetry and other device-to-device applications.

The MDRS network offers a reliable and cost-efficient alternative. There is no risk that other types of traffic, such as voice, may temporarily be given higher priority or block the network.
