I'm looking to buy (or assemble) a handheld warwalking rig, and was wondering what recommendations you all might have.

I'm particularly aiming at rogue device hunting, and would like to have either a PDA or UMPC based unit that can find anything in the 802.11 b/a/n/g ranges. It would be great if I could re-use some of the hardware we already have, but if the only option is to buy a full new system then that can be considered as well.

What we currently have are some AirMagnet handhelds, which are really just a HP iPAQ hx2495b with a Summit SDC-CF20G and some proprietary software. While these do work wonderfully as they are, they are limited to only the 2.4 GHz (802.11 b/g, and some of n) and even then only to the first 11 channels. I need to find something that covers all commonly available 802.11 devices.

As I said, the ideal option would be to re-use the PDAs and just buy some new hardware/software to support our needs. However, I've been having a hard time finding anything that will offer the solution I seek on a handheld platform.

In seeking a commercial product I've contacted AirMagnet to find that while they do have an 802.11 b/a/n/g analyzer, it's only available on a laptop. So far, the only commercially available analyzer that fits the bill is Berkely Varitronics' YellowJacket b/a/n/g. However, this is fairly expensive ($6,500 not counting options like direction-finding antennae) and has many features and capabilities that I don't need. Even the Berkely Varitronics sales rep suggested that I should "home-brew" something instead.

So, any suggestions? Is there a wifi device and wardriving tool that would work with these PDAs and cover the whole b/a/n/g spectrum? Or, does the YellowJacket have some competition I just haven't dug up yet?

Thanks in advance for the input.
