LoRaWAN® standard expands to include Relay Specification

The LoRa Alliance® has expanded the LoRaWAN® standard with the support of a new feature called Relay.
The new relay feature is addressing the issue that, in some instances, it may be economically difficult or not be materially possible to deploy full-size gateways to extend LoRaWAN coverage to a small portion of end-devices. This is especially apparent in use cases with sparse deep indoor connectivity, or for underground smart metering, or with a cluster of sensors around a LoRa satellite module, for example.
In these cases, a low-cost and battery-capable Relay device is the ideal solution.
During this webinar, you will learn:
How a relay can improve LoRaWAN coverage
Technical characteristics and specification basics of the LoRaWAN Relay
How to add Relay to your end-device
The impact of adding this new feature into your end-device

Will there be Relays that also work plugged in? I assume the battery is optional.

We should use the relay as class A. So battery powered.
