Link WAN provides network management, network sharing, and data egress features to help you build private Internet of Things (IoT) networks.
Network management
Link WAN provides network management services, such as gateway and relay management. You can add gateways to Link WAN to build a network and create self-managed wireless coverage areas for the IoT.
Network sharing
You can purchase your own gateways to build a network. Access to the network is granted through network credentials.
