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 interference3. 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 Blocks4. Provide QoS with Low Latency
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
Proposal February 5, 2008
NP Ballot: February 5, 2008 – May 5, 2008Meeting: Geneva, Swiss, April 6 – 11, 2008Meeting: Montreux, Swiss, November 3 – 7, 2008
CD Ballot: November 18, 2008 – February 18, 2009Meeting: Tokyo, Japan, June 1 – June 5, 2009
FCD Ballot: July 14, 2009 – November 14, 2009Meeting: Barcelona, Spain, January 18 – 22, 2010
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.
