Today's wireless handsets are more than just cell phones - they are powerful, portable computing devices optimized for running data applications.

Recognizing that staying abreast of the whereabouts of workers and assets is a critical factor in maintaining an efficient business, Nextel has introduced global positioning system (GPS)-enabled handsets that allow customers to perform various activities and tasks. By using a simple application on a mobile phone, field personnel can perform a myriad of tasks - including completing and sending work orders, receiving work assignments, ordering parts, assessing crew performance, dispatching and routing support, and downloading driving directions.
