Abstract: An IoT service of a provider network may be used to increase the edge device address space while complying with a radio communication protocol. This may allow a service provider to manage a much larger number of client devices that use a particular radio communication protocol that specifies a limited address space (e.g., LoRaWAN). When the IoT service receives a join request via a private gateway of the client network, the service determines, based on the private gateway ID, the client ID of the client that owns the private gateway/client network. The service may generate a unique internal ID for the edge device by combining the client ID with an assigned device ID. The internal ID identifies the edge device as an activated device of the edge network.

Abstract: An IoT service of a provider network may be used to optimize downlink scheduling for edge devices that use a radio communication protocol (e.g., LoRaWAN). A processing instance receives DL packets from a client application that are to be sent to an edge device. The processing instance adds metadata entries (device ID, message ID) to a metadata queue and stores the DL packets into a data store. A scheduling instance obtains a metadata entry and the associated DL packet, formats the DL packet based on edge device information, and publishes the packet to a gateway topic. A separate connection instance receives the formatted DL packet and sends it to a gateway of the client network.

Abstract: A multi-radio service of a provider network may be used to manage and route payloads for client edge devices that use multiple types of radios. The multi-radio service may associate different types of radio controllers with an edge device of a client, so that messages that are transmitted from different types of edge device radios can be handled by different radio controllers. A radio controller may receive a message and extract the payload from the message based on the data/data format specific to the radio protocol used to transmit the message. When a client-owned cloud application sends a payload to an edge device, the multi-radio service may select, based on criteria (e.g., fastest data transmission), the radio of the edge device from multiple available radios. The corresponding radio controller may then generate and send a message to the selected radio of the edge device (e.g., via a corresponding gateway).
