IEEE 802.15.3 PAR• Wireless Medium Access Control (MAC) and Physical
Layer (PHY) Specifications for High Rate Wireless Personal Area Networks (WPAN)– … wireless connectivity with fixed, portable and moving devices
within or entering a Personal Operating Space (POS) (up to 10 meters in all directions enveloping a person)
– … interoperability or coexistence with other 802.15 TG
– … coexistence with other wireless devices in conjunction with Coexistence Task Groups such as 802.15.2
– … low complexity, low cost, low power
– … >20Mbps to satisfy a set of consumer multi-media industry needs for WPAN communications.

802.15.3 MAC Characteristics• Proven support for mobile wireless personal area networks (WPAN)• Enables WPANs to interact with wired infrastructure access points• Enables a WPAN to temporarily separate into two subnets and then
recombine via an efficient re-authentication and re-association procedure• Provides proven protocol support for efficient power management policies• Redundant master coordinators• Repeater service• Virtual data streams (asynchronous/isochronous)• Negotiating QoS parameters in a WPAN environment• Dynamic channel selection and/or migration• Adaptive FEC and selective retransmission ARQs• An efficient Slot Cycle TDMA algorithm for accessing the RF medium• Bounded latencies• Support for negotiating channel bandwidth allocations
All control messages such as: •attachment requests•authentication responses•slot cycle requestsIn addition short data frames could be sent in this period
• Majority of 802.15.3 participants favored 2.4 GHz solution
• Significant minority supported non-2.4 GHz

Rationale
• Industry demand for a simple QoS solution for broadband multi-media distribution
• 802.11a and HyperLAN/2 will need to change to satisfy the consumer electronics industry
• Why not use the 802.15.3 MAC?

Comments/Interest?• 802.11 is one precedence for multiple phys• Users will want compatible solutions• Lots of work on MAC, don’t preclude other PHYs• PHY independent MAC interface, may not need to
do PHY• 2.4 solution simplifies radio decision, don’t cloud
the market• Push our agenda in the 5GHSG• Keep spectral options open• 802.11a PHY not necessarily a good option
