Wi-Fi Networking News has some more dirt on Apple’s Airport Extreme (802.11g). Glenn Fleishman has deduced that the chip manufacturer is Boradcom. Hopefully the base station firmware will be upgradable to interop with other chipsets. I like this part:
The new Apple Extreme Base Station supports access point and bridge mode simultaneously. Deploying several base stations is now a simple solution for smaller networks that need more client access is different places.
I also like the option for adding an external antenna. That’s what I’d do.
