Wanted: 2 Standards on 1 Card
Don't expect the latest crop of wireless protocol analyzers to stand still if dual chip sets that allow wireless cards to support 802.11b and 802.11a achieve traction.Dont expect the latest crop of wireless protocol analyzers to stand still if dual chip sets that allow wireless cards to support 802.11b and 802.11a achieve traction. It mostly comes down to writing a driver that can support features of both chips in a single card, but as our tests revealed, this task is more daunting than might be expected.
IT managers should insist that protocol analyzer vendors get this right because effective wireless trouble-shooting is going to require that a single PC equipped with one of these cards act as a sniffer and a terminal. After ascertaining the nature of a wireless problem, IT technicians will likely have to connect to a wireless access point and configure it in some way. This will require that technicians quickly switch out of "sniffer" mode and into "configuration" mode, which will be a real hassle using current card drivers.
