(DCN12-459-r3) Assumes the model within street canyons or over roof-tops for cellular model. –For the case of that transmitter is base station and receiver is mobile station. –These models are not applicable to PD-to-PD scenario., Slide 5

6. doc.: IEEE 802. 15-13-0013-00-0008 Submission 6.2. Synchronization  Candidate text for sub-clause 6.2. –“IEEE802.15.8 may operate in synchronous or asynchronous mode. When IEEE802.15.8 is operating in synchronous mode, a PD shall maintain synchronization among synchronized PDs during the limited time.” –[Comment] Synchronous mode can support of low duty cycling of discovery and high throughput of data transmission, but with more protocol overheads due to network dynamics. Asynchronous mode can support more simple system with low protocol overheads, but the supportable type of PD may be restricted due to high power consumption., Slide 6
