1 Preliminary Evaluation of Japan Band Issues
January 2003 Preliminary Evaluation of Japan Band Issues Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

2 Top Level Issues How to learn AP/Base Station’s capabilities?
January 2003 doc.: IEEE /xxxr0 January 2003 Top Level Issues How to learn AP/Base Station’s capabilities? Multi-band with rules per band, multi-mode Base Stations licensed, other stations not licensed in some bands IBSS prohibited in some bands 2.5MHz channelization in 4.9 and 5.0 GHz How to signify Channel Ids Carrier sense rules satisfied PCF maximum duration; fragmentation Already required for .11, .11b lower rates Spectral efficiency requirements met by mandatory 16QAM modes Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

3 AP/Base Station’s capabilities?
January 2003 AP/Base Station’s capabilities? Beacon frame format – set dot11MultiDomainCapabilityEnabled Extend multi-domain definition to multi-band .11d Probe Request/Probe Response Information Elements 13- ID, Length, Channel Properties Zero, Channel Properties 1, … Channel Bandwidth, Licensed BSS, IBSS allowed, Licensed STAs, Alternate Band, First Channel Offset (0.5 MHz) Peter Ecclesine, Cisco Systems

4 January 2003 Channel ID techniques .11a Channel center = x n [n=0-199] Could designate [n= ] negative to signify [negative first channel signifies below 5000] Together with ‘First Channel Offset’ signifies center frequency on 0.5 MHz accuracy (examples on slide5) .11g Table 105, enumerated by country Peter Ecclesine, Cisco Systems

5 4.9 and 5 GHz Channel ID examples
January 2003 4.9 and 5 GHz Channel ID examples Carrier freq ‘First channel’ ‘Number of chls’ ‘First chl offset’ = = = = = = Peter Ecclesine, Cisco Systems
