This Recommendation investigates characteristics of wearable devices (WDs) and wearable devicerelated services (WDS), and provides specific requirements and capabilities of the Internet of things (IoT) in order to support them.

The common requirements of the IoT [ITU-T Y.4100] are high-level requirements applicable to WDs and WDS. This Recommendation builds on the common requirements of the IoT and provides specific requirements and capabilities for support of WDs and WDS. These specific capabilities complement the capabilities of the IoT described in [ITU-T Y.4401].

The scope of this Recommendation includes:

– description of characteristics of WDs and WDS;

– specific requirements of the IoT for support of WDs and WDS;

– specific capabilities of the IoT for support of WDs and WDS.

Information concerning use cases for WDs and WDS is provided in Appendix I.

This Recommendation does not address requirements and capabilities of wearable devices themselves.
