Summary (Cont.)
Two motions to request the WG to form new study groups were passed:
Form a new IEEE Study Group called Radio Resource Measurement
Form a new IEEE Study Group called the High Throughput Study Group (HTSG)
and chairs will continue to discuss and consider formal response to ETSI invitation to participate in joint Wireless Interworking Group (WIG) meetings starting in September in Monterey

WNG SC Presentations (Cont.)
Requirements for Home Networking
C. Ware: 02/310r1
MAC needs to evolve for Home Entertainment
Both the PHY and MAC need upgrading
MIMO-OFDM Considerations
Heejung Yu: 02/294r1
Zero Forcing receiver: MMSE receiver
Thoughts on HDR
Jim Tomcik: 02/371r0
QoS is easier to achieve in slotted systems
Hotspots can really use the added throughput & QoS
Next Gen Wireless LANs
Yasuhiko Inoue: 02/308r0
Basic rate of 100 Mbps with options to 2x & 4x speeds

WNG SC Presentations (Cont.2)
UWB Teleconference Report
Richard Paine: 02/336r0
Implications of FCC Ruling on Part 15
UWB indoor and handheld masks
FHSS in 2.4 GHz spectrum lowering number of hops to 15 provided system uses no more than 125 mW
2.4 GHz opened to other technologies
Still not enough for UWB as an PHY but not ready to write off
PHY Frequency possibilities
ISM 902, 2.4, 5.75
UNII

WNG SC Presentations (Cont.3)
Overview of activities in SG3a
Rick Roberts (Chair SG3a) presented
Talked about CFA (8 applications)
