Which solution is suitable?] Date Submitted: [29 October 2009] Source: [S.M. Ryu, D.Y.Kim, J.G.Han] Company [Casuh Corp., Chungnam University, & PicoCast Forum] Address [#813 Leaders B/D, 342-1, Bundang, Seongnam, Kyeonggi, 463-828, Korea] Voice: [+82-31-709-5577], FAX: [+82-31-709-5578] E-Mail:[retaw@casuh.com, dykim@cnu.kr, & jhan@picocast.org] Re: [In response to 802.15 WNG call for presentations.] Abstract: [In the future, most of users want to maintain their environment mobility within a moving personal space. 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.

  30. 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.
