GPRS Modem

GPRS modem can be used for remote wireless, machine to machine or user to machine and remote data communications. A GPS vehicle tracking system is an essential component of vehicle management system and vehicle management solutions.

GPRS Modem

A GPRS modem is a GSM modem that supports GPRS. GPRS (General Packet Radio Service) is a packet switching technology for GSM networks. GPRS modems do not require a constant connection to the Internet as with a standard modem, because it uses the network only when there is data to be sent. GPRS offers faster data transmission and instant connections, subject to radio coverage. GPRS Modem fully enables desktop Internet applications over the mobile network. Other applications for GPRS Modems include file transfer and home automation. GPRS can be used in vehicle positioning applications to deliver several services like remote vehicle diagnostics and stolen vehicle tracking. To enable GPRS on a GSM network, two core modules need to be added:

· The Gateway GPRS Service Node (GGSN)
· The Serving GPRS Service Node (SGSN)

Vehicle Management System

A Vehicle Management System allows an organization to monitor and manage its fleet of vehicles more effectively and efficiently. An operator can monitor vehicle movements, retrieve any vehicle's history and verify that the vehicles are traveling on predefined routes using vehicle Management Systems. On some vehicle Management Systems, the operators can also send out radio communications, text and status messages. Thus a powerful, two-way communications tool is created, enhancing the organization's performance and productivity.

Benefits of a Vehicle Management System

· Improved vehicle management
· Considerable savings in time and cost
· Improved two-way communications
· Meeting productivity targets on time
· Enhanced safety and security

GPS Vehicle Tracking System

A GPS vehicle tracking system is one of the important applications of GPS that brings it into the day-to-day lives of people. Cars, ambulances, fleets and police vehicles fitted with tracking devices are a common sight. A GPS vehicle tracking system is an effective tool for improving the operational efficiency and utilization of vehicles. Irrespective of the technology used, this system is made of

· In vehicle unit
· Base station
· Communication link

Tracking systems enable a base station to keep track of the vehicles without the intervention of the driver.

GPS Locating

GPS locating was a solution offered to the caller location problem for users of cellular phones. GPS was predominantly used for navigation applications, for instance to guide ships and airplanes. Soon, GPS-based location services became popular. But GPS locating is not very effective because of the many obstructions that block the signal when using it on land. GPS always requires a clear line-of-sight to be effective.
