  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) • Submission Title: [Personal Space Communication with WPAN Broadcasting] • Date Submitted: [10 March 2010] • Source: [S.M. Ryu, J.U.Seo, D.Y. Kim, Y.J.Park, & C.H. Yon] Company [PicoCast Forum, ISO/IEC JTC1/SC6, IEEE Region 10, LG Telecom] • E-Mail:[retaw@casuh.com, juseo@picocast.org, dykim@cnu.ac.kr, yjpark19@gmail.com, chyon@lge.com ] • Re: [In response to 802.15 WNG call for presentations.] • Abstract: [In the future, most users want to maintain their personal space within a fluid, moving environment. Service providers should approach and broadcast their services to these user spaces, allowing users to select service amongst broadcasting services, as if selecting a radio channel. Thus, if service broadcasts within personal spaces became standard, then the Personal Space Communication (PSC) based on WPAN technology will become a leading & killer application for Ubiquitous services in the future. We can ascertain that connections of PSC spaces will represent a large part of future 5G mobile communication.] • Purpose: [Information related to the request for international cooperation] • Notice: This document has been prepared to assist the IEEE P802.15.
