So, Personal Environment Service(PES) based on WPAN technology would be leading & killer application of Ubiquitous services in the future. We can figure out 5G mobile communication is only the connections of the PES spaces. ] Purpose: [Information for asking international cooperation] Notice: This document has been prepared to assist the IEEE P802.15.

Conclusions What is the PES ? Facilities surrounding users can be automatically configured to user preference. The user interface environment within user space follows when a person moves. It provides broadcast, multicast, communication & sensor convergence service. User terminal can select a service among services broadcast by providers. It could be leading & killer application of Ubiquitous services. What kind of WPAN solution is suitable for PES ? Dual support for both low power sensor and high speed multimedia. Container concept to reject mutual interference and converge various services. Abundant channel capacity based on avoidance of mutual interference. Hierarchical sync & frame structure for scalable & self organizing system. PES Protocol can be used for 5G mobile communication, too. PES personal space & mobile femto-cell have almost the same structure. In the future, the cell size of 5G will become femto-cell because of capacity. 5G network merely a connection of user oriented mobile spaces. White space devise requirements would be satisfied with PES protocol.
