A wireless wide area network, or WAN, uses long-range connections to provide access over a much larger area than wireless LANs, which usually cover just one building or campus. They work on the same networks as cellular phones. Essentially, anywhere you can get a cell phone signal, you can access a wireless WAN.

These wireless WANs, plus On-Call Computer Services Mobile Wireless Solutions are perfect for people who spends a lot of time away from the office but need access to everything back at their desks: Real estate agents, traveling salespeople, delivery personnel, and corporate executives.
