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.]

Why PicoCast ? - Capacity
How to increase mobile channel capacity
?
 Find new frequencies that haven’t been developed?; no more available
 Find new signal processing techniques ?; only few times increasable
 The only way to achieve few thousand times capacity ; reduce cell size

Solutions for Challenges
1. Near / Far Interference



Chg. : Shall not receive while adjacent devices are transmitting, even at
different frequencies
Sol. : Synchronized Frame can reject mutual interference among PHYs
128bit multi preamble is necessary to enhance sync. probability
2. Single MAC to support Multi-PHYs


Chg. : Single PHY cannot meet wide user service requirements
Sol. : Container Concept accommodates various information Boxes
Synchronized Frame can support different PHYs without interference
3. Tradeoff between Power & Speed


Chg. : Low power sensors and Medium speed multimedia should be supported
Sol. : Single MAC for Multi PHY concept can support Multi RF Block
Sensors use single RF Block; Multimedia uses multi RF Blocks
4. Provide QoS with Low Latency


Submission
Chg. : Ensure broadcasting performance and low latency without ARQ
Sol. : Frequency and Time hybrid diversity algorithm is necessary
Time diversity only cannot overcome multi path fading effect

Overview of ISO/IEC 29157

Why ISO/IEC29157(PicoCast) is suitable for PSC service ?





Container concept supports both low-power sensor & medium-speed multimedia.
Abundant channel capacity due to avoidance of mutual interference.
Provides broadcast, multicast & communication convergence protocol.
Local broadcasting gives an additional business model such as advertisement.
Adaptive common channel signaling supports mobile communication protocols.
