The 3GPP may have finalized its NB-IoT specifications (see separate item), but one of the rival technologies in unlicensed spectrum, LoRa, is already pushing into networks with national, commercial coverage, and has attracted heavyweight support from Cisco. The fact that large cellular operators – in this case SK Telecom of Korea and KPN of The Netherlands – are deploying LoRa at scale, even with a 3GPP alternative on the horizon, suggests that the unlicensed spectrum LPWANs (low power wide area networks) will play a significant role in the future IoT – and not just for operators which lack access to licensed spectrum. For some services which do not require the security and guaranteed QoS of licensed bands, technologies like LoRa…
