10 END OF YEAR REPORT 2017 5.0 KEY TECHNOLOGY ENHANCEMENTS IN 2017 2017 was a very active year for enhancing and strengthening the LoRaWAN protocol, with the following upgrades announced: • New features in the latest specification releases include roaming and separation of back-end nodes, which will enable IoT devices to connect to and move between LPWANs around the world. This supports large-scale deployments and enables new global services such as cargo tracking. Such features are critical in the Alliance's mission to standardize LPWANs globally and drive widespread adoption of the LoRaWAN protocol as the de facto standard for IoT connectivity. - LoRaWAN 1.1 with support for handover roaming, and Class B and security enhancements - LoRaWAN Backend Interfaces 1.0 with support for decomposing the network into interoperable nodes, as required for inter-vendor roaming. The new back-end specification provides the protocols that interconnect servers with distinct roles––such as controlling the MAC layer, end-point authentication or applications––behind the scenes in the core network. Separating these servers allows an open choice of vendors for each element of the value chain, empowering the ecosystem. - LoRaWAN 1.1 Regional Parameters rev. A, which describes region-specific radio parameters for LoRaWAN 1.1 end-devices
