6 Considerations p. 44

A lot of the use cases in this document are based on existing systems (e.g. ZigBee® Specification [9], Z-Wave ® [10]]) that can be deployed today, in fact the overview identifies two main Personal IoT Networks, wearables and home automation. These existing Personal IoT Networks use a number of different technologies that provide a set of capabilities.

8 Conclusions and Recommendations p. 48

This document analyses a number of use cases related to Personal IoT Networks, the resulting potential requirements have been consolidated in clause 7. In addition, when the use cases where being written for this TR some overlap was seen with use cases TR 22.858.

It is recommended that the consolidated potential requirements identified in this TR and TR 22.858 are considered together as the basis of normative requirements.
