This document discusses LoRaWAN roaming, including: 1) Types of roaming like passive roaming and handover roaming. 2) Implementation steps like developing specifications, obtaining a network ID, and partnering with other networks. 3) The LoRa Alliance's activities to support roaming like developing backend interface specifications and running a roaming working group. 4) ThingPark's role in enabling roaming through its network management platform and developer tools.

Copyright ©Actility Passive vs Handover Roaming 13 Criteria Passive Roaming Handover Roaming Applicability All devices (transparent) LoRaWAN 1.1 devices Macrodiversity Yes No Channel plan overlap Minimum level of overlap needed Radio configuration exchange among networks Needed Not needed L2 control In home network (home may favor for better device management) In visited network (visited may favor for better radio network management)

Handover Roaming will come later (dependency on LoRaWAN 1.1 devices).
