Mobile WiFi antennas give truck drivers, RV vacationers, and other mobile individuals unending access to the Internet, so they needn't keep their laptops or PDAs at home, and can consistently stay connected to their families or their employers.

As though such devices weren't enough, WiFi lovers can now use a sniffer, which is a wireless tool that detects the presence of other wireless devices, calculates the strength of their signals, and provides a report to the owner on the position of the access point.

Or, the managers of a shopping mall could use their device to track the amount of people who connect to their network, and then raise the cost to derive more profit from their clients.
