Belgian operator Proximus is working with local start-up Tessares on a trial of an LTE/DSL hybrid technology which could lower the cost of connecting the underserved user base by combining wireless and wireline resources. The trial uses Multipath TCP, an emerging IETF standard which enables TCP sessions to spread out across multiple paths for increased redundancy, and also to increase bit rate over networks where bandwidth is constrained, such as cellular. Despite not being finally ratified, it has been deployed, most famously by Apple for its Siri voice recognition app on iPhones and iPads, where it improves QoS by minimizing impact of intermittent throughput over individual paths. Proximus is testing it for a purpose which is increasingly popular among owners…
