Do Extended-range WLAN technologies deliver?

Longer range and faster speed are the watchwords for wireless LAN product manufacturers and the criteria by which many of us choose which products to buy. We take a look at three "extended range" WLAN technologies - Atheros' Super G / XR, Airgo Networks' True MIMO and Parker Vision's D2D - to see if they deliver as promised.

Ever wonder if the extra money you pay for an "enterprise" access point is buying the ability to handle heavier traffic loads than the $100-or-so AP on your local retailer's shelf? We did too until we put six 802.11g APs through some pretty heavy load testing, with some surprising results...

Wardriving: Taipei Style

NeedToKnow: WiFi PDAs’ Dirty Little Secret

Updated PDA manufacturers have been previously caught "optimistically" specing both available memory and the number of screen colors really available in their products. This NeedToKnow shows that they also have some work to do to convey to prospective buyers the wireless speeds that their 802.11b-enabled products can really deliver. We found some surprisingly slow products, but also some that deliver what you'd expect from a device with WiFi inside.

Enhanced 802.11g NeedToKnow

One of the wireless networking stories at this year's Las Vegas CES - aside from the scads of networkable DVD players and "media adapters" - was the battle for bragging rights to the highest throughput "starburst" number. (The "starburst" is the number prominently displayed on the front of a product's box).

Atheros Super-G NeedToKnow – Part 2

In Part 1 of this NTK, I described the elements of Super-G and took a detailed look at normal 11g and Super-G channel overlap. I also presented test results pitting Super-G against "normal" 11g wireless LANs and "normal" 11g WLANs against each other.

Atheros Super-G NeedToKnow – Part 1

As I described in my Comdex coverage, the short story is that Broadcom is asserting that Atheros' Super-G based products will interfere with neighboring 802.11b and g networks, severely limiting their speed and, in some cases, shutting them down completely.
