Is there a USB wireless adapter that can operate with its own battery and its own operating system, without being inserted into a mobile laptop or PC?
USB is the interface used by the wireless adapter to communicate with a laptop or desktop, so I do not think you are actually looking for a USB wireless adapter. I suspect what you want is a mobile 802.11 device that is smaller or less expensive than a laptop. How about a PDA with a built-in 802.11 adapter? For example, see the HP iPAQ hx2415 Pocket PC, the Palm Tungsten C, or other PDAs listed on the
certified products list. Or use an inexpensive PDA with an SDIO or CF slot and a third-party 802.11b/g adapter, like the Intel PRO/Wireless 2011B, Sony 114100, or Symbol LA-4137 compact flash adapters. If you just want to know whether an 802.11 network is in the area, try a $30 Wi-Fi Finder -- but these devices won't let you run applications that use wireless, they just detect wireless signals.
