the quality of the radio connection with the Access Points. As the client moves away from its
Access Point and the signal level decreases, the RoamAbout PC Card automatically connects
to another Access Point in the same network that has a stronger signal level.

the radio signal (signal level) versus the radio interference (noise level) in the radio signal
path.

fork-lift trucks that need continuous access to networked data while inside or outside of the
warehouse.
