802.11b at 22mbps

Radi-0-head writes "According to this article at PCWorld.com, "U.S. Robotics (USR) has boosted the speed of its latest range of wireless LAN products for small businesses to 22 megabits per second, while retaining compatibility with existing 2.4-GHz systems built to the IEEE 802.11b standard..." Sounds to me like a great alternative to 802.11a."

What's the REAL speed?

[chill]

11 Mbps to 22 Mbps SOUNDS like a 100% increase, but what is the real speed/range gain? Given an 11 Mbps system with 3 nodes each at 10m from the access point, what is the actual thruput? Is switching to the USR system going to actually DOUBLE that?

Network speeds rank right up there with CRT sizes, CD-ROM spin speeds and tape storage capacity as some of the biggest bullshit numbers in computing.
