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."

    5.) It's still too slow to download Celeste-Virtual_BJ.avi in a reasonable time
    4.) You're not a cafe communist with a computer and a four dollar cup of coffee.
    3.) The low-bandwidth version of Slashdot doesn't have those cool 1997 .GIF icons.
    2.) The babes dig retro shit these days, like 14.4bps dial-up.
    1.) Your life revolves around physical things, not six-hundred dollar mp3 players (iPaqs, etc.)

    Ugg. We've known we were getting screwed since before the "56k" modem. Nothing ever goes that fast. 1ghz processors are actually 998.5 mhz. Foot long hot dogs are actually nine inches.

    yes, if you equip it with a hack saw and a roll of duct tape so I can put it in my pocket and reassemble it afterwards.
