Misc System Information


In March 2019, Tait completed the digital upgrade of Transport for London's surface fleet, fitting London's red buses with digital radio communications.

The radio system provides robust and reliable voice and data connections between all buses and TfL's network of dispatch and control centers. Tait designed the new system to be both a resilient system for today's needs and as a digital platform for future applications.

The on-bus equipment is based on the Tait Unified Vehicle platform, which gives access to multiple bearers in addition to mobile radio, including cellular and WiFi, and the ability to run custom applications to improve operational efficiency and the service provided to travelers.

For a communications network of this size, proactive monitoring and management is essential. To ensure the network is running smoothly and its performance and TfL's compliance to KPIs could be measured, the network is managed and monitored by Tait EnableInsight software and Tait Managed Services around the clock.
