Unit 3

Unit General Packet Radio Services known as GPRS has been around for quite some time. It was established in the early 2000s and is widely used across the world today. It is an extension of the global system for mobile communication. GPRS works by allowing data to be stored into ‘packets’. This data is then transmitted in an efficient manner across the mobile network. GPRS, however, is much faster than the cellular network system. This type of networking system can be used worldwide without difficulty. GPRS devices are extremely versatile. Any device that has GPRS capability will allow the user to have not only mobile communication but also access the internet for things such as e-mail and internet browsing. You can even adjust various settings on the device in order to keep track of things like changes in temperature, sound and motion. Car tracking devices are cheaper and easier to install. They mainly work via GPS satellite navigator, although in some cases a radio frequency or cellular network can be used, if GPS coverage is poor. The actual set up is really very simple; each vehicle transmits a signal to orbiting satellites which relay this information back to a specified computer. The vehicle information is then displayed on maps, allowing you to monitor speed and exact whereabouts. By utilising real-time vehicle tracking you can get accurate information about the travel. Although this system enables you to avoid traffic and find the quickest road to travel, you will still find an excuse to be late!
