Radiation Pattern” or SRP, a measurement in RF Energy, for the
USR8054 is only slightly stronger (~ 94) in front of the unit, nearly
the same at 45 degrees, but only slightly weaker at the sides (81-82).
Since the US Robotics Turbo Router has the capability of being set for 802.11G only or “mixed mode” (allows .11B too), we tested for both.
If you look at the
charts below (click on the images to enlarge), you will see
that the USR8054 802.11G Wireless Turbo Router performs best with its
own PC Card. However, note that most other brands of .11G cards did
well too, except that Broadcom chip-set cards only connected at 48 or
36Mbps bandwidths and lower as distances increased. Remember that Texas
Instruments has warned of incompatibilities with the Broadcom chip-set
used in the Linksys (and Asante) .11G hardware. These lowered 48 and
36Mbps numbers seem to prove the TI claims.
When the mode selection for 100 G “Only” is used, any 802.11B-equipped device is naturally locked out of the WLAN. You’ll notice when comparing the two test results pages, that the signal strength goes up for the US Robotics PC Card, but down very slightly for other “turbo” enabled .11G cards. Since the Apple, Linksys and Asante .11G cards do not have a “Turbo Mode” they are also locked out.
In the 43MB file test download to a US Robotics USR5410 PC Card equipped and a D-Link DWL-G650 PC Card equipped notebook, we tested the USR Turbo-G Router set in both “Mixed” mode and “100G” only mode. Here are the results:

Keep in mind that you WOULD expect like chip-set devices to be faster than mixed competitive chip-sets.

Turbo Router our 2004 Editors' Choice Award as the Best All Round "54G
If you have a Mac PowerBook, such as a G3 Wallstreet, PDQ, Lombard, Pismo (G3 FireWire) or any G4 Titanium PowerBook, and you want to go over to 802.11G hardware, this is the card for you. Remember that you must be running OS X 10.2.6 and Airport 3.1.
Your Mac PowerBook must also have a CardBus Slot which some first generation G3 PowerBooks and older 603e powered PowerBooks, don’t have. This card also works perfectly well in a Windows PC as well; drivers for Windows are included with the card.
The version of the card we had is an AL5402-XG, and since receiving our test unit, Asante has issued a newer AL5403-XG version which officially supports WPA, however this doesn’t affect performance for the purpose of our tests.
The Asante FriendlyNET AeroLAN-XG card performed equal to or better than the same Broadcom chipped Linksys PC Card, all applications. In some cases the AeroLAN-XG ran at a higher bandwidth than the Linksys in exactly the same notebook computer; we have no idea why this should be the case.
With OS X 10.2.8 and the most current version of Airport installed on each of our PowerBooks, installation was no different than if you had just used an original Apple Airport 802.11B card. In fact if you have an Apple Airpor .11B card installed in your G4 Titanium, just merely turn it off in the Control Panel, shutdown the G4, insert the Asante FriendlyNET AeroLAN-XG card into the CardBus slot and reboot.
