Hello LK. We've installed several Cisco 1130AG's around one of our
offices. They're an excellent, enterprise-class product. It has two
radios in there, offering tri-band operation (a/b/g). We have some
users connect to the 'a' radio, and others, the 'b/g' balancing the
load. Runs Cisco IOS, very good for trouble-shooting problems.
The Cisco badge does come with a weighty price tag! (here in the UK
anyway)

Is that the kind of thing you're after ?
Cheers, Stuart.
