Portable storage and moving company 1-800-Pack-Rat has implemented TeleNav's cell-phone GPS technology to increase efficiency and better serve its customers. TeleNav Track is a mobile resource-management service that provides real-time information for managing field operations and enhanced on-the-go communications. The service will be used to improve communication with drivers in the field and to assist with obtaining turn-by-turn GPS driving directions on demand. The new GPS technology will also help the company manage scheduling, locate trucks and monitor the safety of the fleet. With TeleNav Track, drivers may view appointment changes directly on their cell phones. In addition, dispatchers can observe driving speeds, compare progress against drivers' routes and calculate exact arrivals in real-time. Info: www.telenav.com
