SureWAN™ Aggregation Protocol
SureWAN™, Icomera’s proprietary core technology, empowers our onboard routers to intelligently connect to multiple cellular and other communications networks simultaneously, aggregating all available capacity to deliver the fastest, most reliable connection possible to a moving vehicle.
When the connection from a particular network is lost, SureWAN allows Icomera’s mobile connectivity and applications routers to retain all other available connections, improving the onboard connectivity’s reliability, even in regions with sparse network capacity. This seamless transition between different networks provides an always-online experience for passengers and onboard systems.
The SureWAN algorithm accomplishes maximum data capacity, coverage, availability and redundancy, and minimises data packet delay or loss. Since 4G, 5G, TraXside™ and even satellite networks can all be supported as part of a single solution, SureWAN delivers higher throughput than would otherwise be available from 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. By setting priorities on different networks, SureWAN can also prioritise data transfer over lower cost links (e.g., rail yard / bus depot Wi-Fi), when such links come into play.
SureWAN 4.0: A Fourth Generation of Innovation
The technology’s fourth major update, SureWAN 4.0 enables 5G speeds by further optimising how the algorithm aggregates multiple communications networks. SureWAN 4.0 delivers significantly improved system performance by increasing throughput, lowering latency and reducing data packet loss, making the algorithm more responsive and efficient than ever before. Increased 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 fewer data packets need to be re-sent.
These latest improvements to SureWAN mean that passengers utilising Icomera’s onboard Wi-Fi for services such as Internet browsing, VOIP and video conferencing calls can benefit from an even faster, “snappier” user experience, while the connectivity for Internet-enabled onboard systems is faster and more reliable than ever.
