A couple of general questions about 802.11 at IETF in Japan 1) is there some aspect of the telecommunications/regulations here in Japan restricting the number of channels for RF use which affected the problem? Did it help or hinder? -This is a 'cannot fix' problem for IETF, but would be interesting to know, and to try and feed back into national regulatory process for RF management. After all, the density of endpoints and stations is probably close to a future world dream. 2) is there some aspect of the density of wireless stations, station names and SSID behaviour which contributed to the problem? I am hearing gossip which suggests in some cases in RF space 'more is better' is a false model, and that 3 stations in rooms where 4 are, might be cleaner. A consideration here is that people choose to sit close to the middle of the room, and some rooms the aerials are in the corners so the area of maximum overlap of signal is ... the weighted centroid of the middle of the room! Or the ven diagram overlap or whatever. Maybe more 'randomy' placement of the stations, or all along one wall would be better? I don't know. Could that kind of thing be tested passively with an RF meter rather than with the massed laptops of IETF? (and the hosting BCP updated...) And, the tricky third question ....or is this just yet another complexity which cannot be solved by single-point changes... cheers and thanks to the NOC who are clearly working very very hard to deliver the best 802.11 they can, in trying circumstances (Typhoons do not help with external aerials, rogue SSID ad-hoc, and who knows what else) -George -- George Michaelson | APNIC Email: ggm@apnic.net | PO Box 2131 Milton QLD 4064 Phone: +61 7 3858 3100 | Australia Fax: +61 7 3858 3199 | http://www.apnic.net
