smart devices to cell towers. However, this system cannot meet the ever-increasing demand for data, since a single Mobile Network Operator (MNO) is often unable to offer sufficient coverage and capacity along the entirety of a vehicle’s route.

Invented in 1999 and improved upon ever since, SureWAN™ is Icomera’s proprietary core technology. Specifically designed for use on public transport, SureWAN empowers Icomera’s multi-modem mobile access routers to aggregate all available cellular capacity

Geographical patches of poor coverage and capacity mean that the Internet connection’s strength and stability vary, resulting in connectivity that is unpredictable and

aggregating all available spectrums to accomplish maximum data capacity, coverage, availability and redundancy, and to minimise data loss from handover. Since 4G, 5G, trackside and even satellite networks can all be supported as part of a single solution, SureWAN delivers higher throughput than would otherwise be available from just a single network. This enables passengers to enjoy more time online, and onboard systems to transmit data back to base in real-time, on demand. ●

Least-Cost Routing: By setting priorities on different networks, SureWAN can prioritise data transfer over lower cost links (e.g. rail yard / bus depot Wi-Fi) when such links come into play.

By working together in harmony, our hardware, software and technology combine to deliver cost efficiency, long-term reliability and provable results.

throughput means that more data can be transferred within a given amount of time, lower latency means that there is a reduction in the time it takes for a data transfer to complete, and reduced data packet loss means that
