Mobitex Technology - Technology - Features

Secure and instant communications at all times

Mobitex is the most reliable, secure and robust wireless packet data network on the market. Store-and-forward technology is used to guarantee delivery, which means that if a vehicle is temporarily out of coverage the transmitted data is stored in a mailbox and forwarded as soon as the vehicle is back in coverage. Intelligent design, sophisticated functionality and first-class equipment eliminate the need for redundant network elements. These features do not only give Mobitex high in-service performance figures, they also save money for the network operator or owner who can make maximum use of available resources in the entire network rather than spending money on reduntant hardware.

Guaranteed and instant network access
The Mobitex network is always available and instantly accessible; devices are always online and ready to receive data or send notifications. There are no time-consuming call set-up or data activation procedures - and there are no busy signals. Response times are short and access is instantaneous. Since packet switching does not require a dedicated connection, devices can remain online at all times, sending and receiving data as required by the application.

Unparallelled capacity
The Mobitex network is designed to handle large numbers of subscribers or devices, as well as large volumes of data traffic at a very low cost. Because of its excellent capacity and many features, new applications and solutions can usually be added to a Mobitex network without further investments.

Adaptable to all sizes
Because of its flexible and scalable nature Mobitex networks are deployed in very different configurations, from small private networks, owned by a single bus company and used for local or regional operations, to large public networks offering nationwide wireless data services for a wide range of applications for mobile professionals. Using Mobitex, expanding coverage as well as enhancing capacity in existing coverage areas with heavy traffic is done easily by simply adding more base stations.

True push functionality
Mobitex accommodates true push functionality. Without being requested, a host can initiate a transmission to a remote device, hence "pushing" the information forward. This functionality is particularly useful in command-and-control functions and for telemetry and other device-to-device applications. Mobitex also supports push functionality to pre-defined user groups (e.g. all buses, all trains, all signs or all ambulances).

Industry leading battery life
Even though users are always on-line, making frequent use of wireless data services throughout the day, power-saving features in the network ensure long battery life. The Mobitex radio protocol includes functions dramatically reducing the power consumption of portable and handheld devices. To further reduce power utilisation, the network features a deep sleep mode which increases battery life up to 16 times and enables these handheld devices to run up to three weeks on a standard AA battery.

Fast response times
Most wireless data applications do not require high speed connections. Broadband speed is basically only required for large file transfers and full multimedia. Messaging, email, telemetry and many enterprise applications, such as sales force automation, work perfectly at speeds below 10 Kbps. Mobitex provides a "fast enough" packet switched network for these purposes, whilst also providing high security, reliability and always-on services. Mobitex illustrates that speed is merely part of the equation. Mobitex is fast because it has low latency, meaning that the round-trip data time is short.

Security against intrusion
Mobitex has built-in redundancy in order to continue working in case part of the network is damaged. Sabotage of switches, base stations or transmission lines has no effect on communication. Data messages are very difficult to eavesdrop and lost terminals can easily be removed from the network. Applications with end-to-end encryption can be used for sensitive operations.

Proven success on a global scale
Mobitex can handle a wide range of data communication functions and is separated from general consumer traffic. Flexible and rapid deployment options and redundancy functions ensure a reliable and secure communications system.
