Our company has a centralized IS department. We go out to the remote sites, do a site survey and install a wirless network. But over time the layout of the building may change and that in turn will cause a change in RF reception. I am looking for a small, simple device that I can give to a user at the remote site, so they could verify signal quality. One thought was a cheap PDA with a 350 card and ACU. Another thought was a product called 'Airmagnet'. Does anyone have experience with this type of device?
