It has taken awhile, but I've managed to round up a few more wireless PDAs whose manufacturers were willing to submit so that I could see how fast they send and receive wireless data.
To recap, Part 1 of this series showed that while there are more PDAs appearing with wireless LAN capabilities, their speed is surprisingly slow. Table 1 summarizes the Part 1 findings from my FTP download testing (from access point (AP) to adapter (STA) under test) and shows the palmOne Tungsten C beating the other products tested by a wide margin.
|Product||FTP Transfer rate

2.7Mbps (333 kBytes/sec)
1.0Mbps (126 kBytes/sec)
|Dell Axim X3 / SanDisk SD WiFi||
0.4Mbps (49 kBytes/sec)
|HP H2210/ SanDisk SD WiFi||

This time, I've tested Dell's Axim X30 624MHz model, plus palmOne's new WiFi card for its Zire 72 and Tungsten T3. I've also pulled in the results from my review of SanDisk's updated SD WiFi card that supports the discontinued Zire 71 and rolled all my results to data into handy comparison graphs.
