When 54 Mbps isn't 54 Mbps: 802.11g's Real Speed

eggboard writes "Matthew Gast, author of 802.11 Wireless Networks, filed this article for O'Reilly Networks explaining exactly how fast 802.11g really is: that is, what's the actual data payload and real throughput, not the rated maximum speed. His conclusion? In mixed 802.11b/g networks, which will be common for years to come, g is only 1.6 to 2.4 times faster than b, not 5 times faster as it is in its g-only mode. This article has real math based on the specs, rather than armchair speculation."

    of right.

    it's obvious buy now that va lairIE is not going to byte the cloven hoof that feeds him, so it becomes ownus to the formerly outspoken commondear robbIE, to return/include the focus to stuff that really matters.

    failing that (which you are miserably, by the way), we'll just do it buy the #s.

    avoiding responsibility/pretending that you are not involved, does not make it go away. check yOUR motiffs.

    consult with/trust in yOUR creator, etc...

    the lines are all open,. yOUR 'fans' are waiting. tell 'em robbIE.

    Why weren't they [msnbc.com] taken alive? Why not teargas and SWAT team?

    OK, lets say you are one of the people that entered the home. You were shot at. Do you want to go in again, and get shot at more? They tried a swat style entry, were shot at, so decided to retreat and shoot back from a safer position. Sure, it would have been nice to have them alive, but why risk more US deaths for it? The house had bulletproof windows, who knows what other fortifications lied inside? If you have bulletproof windows, theres a good chance you have gas masks as well, so the tear gas option is out. The troops tried a peaceful resolution, when that failed, entered the house, WERE SHOT AT, so decided to light it up. Seems to me they did everything they could before resorting to deadly force.
