WRAPI is a software library that allows applications running in user space on mobile end stations to query information about the IEEE 802.11 network they are attached to. WRAPI 1.0 is implemented on the Windows XP operating system and is a hardware-independent tool that works with any IEEE 802.11b wireless network hardware vendor.
The hardware requirements for running WRAPI are as follows:
WRAPI
provides an interface to applications requiring information about the
Wireless LAN. The parameters that are supported are listed in the
table below. The entries in the "Query" and "Set" columns denote
whether the parameter is "read-only", "write-only", or "read-write".

Our research is supported by a grant from Microsoft Research,
Redmond WA. We would specially like to thank Victor Bahl for providing
us the expertise and contacts for support with Windows
technologies.
An earlier version of WRAPI was developed at Microsoft Research, WA by
Gavin
Holland. This version worked only with wireless hardware from
Aironet Inc. and had similar functionality. Our version of WRAPI is
hardware-agnostic, and can work with any wireless hardware vendor.
