Is There Too Much Enthusiasm Over Wireless?
lukOh asks: "in the US, 802.11b/g (2.4Ghz) devices use an
83Mhz-wide frequency range; in-use channels spanning 22Mhz and centered on one of 11 5Mhz steps (badly named as "channels"). This means there should be no more that 3 networks in close proximity, 5 'channels' far from each other, to avoid harmful interference. Now, in the middle of the mixed area where I am, the number of usable WLANs (SNR>20dBm) has gone from 10 to an unworkable number of 20, in just one month. Has the community/the market overestimated the practicality of wireless networks? Are we generally relying too much on such a young, IMHO immature technology made on 'startups hope' and broken firmwares? How can this mess possibly be handled in a working environment, especially the moment your boss asks you to give him access to 'the wireless'?"
"Access points can be easily detected, but the same isn't always true for every single client (or Bluetooth device) searching or using a network. Bluetooth itself employs the same 2.4Ghz range with 1Mhz-wide channels and much less power. To avoid interference a device jumps channel-to-channel, when the currently selected one is busy.
Most WLANs are managed by less-than-perfect SOHO access points. Connecting to an AP in such an environment is a gamble (even from 1ft away), especially when: WPA/WPA2 must be used; 802.11g stability is a dream; anywhere up to 7 networks are on the same 'channel' (1 and 11, being the most used, are standard on many devices); and now 'channel wars' are very common (i.e. 2 or more users concurrently hunting to set a free channel for their network, making the entire range unusable for hours)."

No one else is using it.
Dude, if you're gonna shoot, shoot. Don't talk.
Besides, nobody may understand what the hell you're talking about, but some will pretend they do, just to score some karma. Hell, you might even get a response that reads like it was lifted directly from a rejected fanfic script for ST:TNG!
Geordi: True, a 1-6-11 spread will maximize the spectrum with minimum nodular-crossinterference, but a triple-stepped 4 channel spread will remodularize the wifi matrix-
Riker (adjusting uniform): which would maximize headerless throughput and give us another 10 Teracycles on the core processes!
Picard: Make it so.
Troi: I'm feeling a sense of accomplishment here.
Chewbacca: Arrrr!
