From the developer:
Other wireless site survey tools require significant existing infrastructure, or extensive investment of time for walk-abouts with a scaled floor-plan. Information Systems Auditors and Information Security personnel often don't have access to all required physically-controlled space. In addition, installed Wireless Access Points (WAPs) with site survey capabilities typically do not cover all of the space -- if they are installed at all.
