What Does GPRS Stand For and How Does it Work?

What is GPRS?

GPRS stands for General Packet Radio Service. It is a non-voice wireless Internet technology that is very popular due to the fact that it can support both phone calls and Internet data transmission. Some GSM, or  Global System for Mobile Communications,mobile phones  can even handle both phone communication and Internet access at the same time. It transmits data packets on GSM systems where cell phone channels are shared.

How Does GPRS Work?

In GSM cell phone systems, there will always be idle radio capacity. This is the capacity of a network provider that is not being used and it stays unused until other cell phone users decide to make phone calls. GPRS uses this idle radio capacity to establish a data network to be used for data transmission. If a network provider's idle radio capacity decreases, which means a lot of phone calls are being serviced, data transmission and speed decreases as well. Cell phone calls have a higher priority than Internet data transmission in cell phone network providers.

How GPS Phones Work

GPS Phone works

Global Positioning Tracking uses the concept of triangulation to calculate the location of the cell phone. Satellites and the cell phone are used as the landmarks for this purpose. A GPS tracking system can be used to give both real-time and historical navigation data as it uses the Global Navigation Satellite System (GNSS) network. The GNSS network incorporates a range of satellites that use microwave signals, and these signals are then analyzed to determine the location of the cell phone. A GPS device receives signals from the GPS satellites, and if it can receive strong signals from three or more satellites, then the location is calculated accurately. However, if the signals are weak, it could be difficult to accurately locate the cell phone. An important aspect of GPS tracking is that a GPS device cannot send signals; it can only receive them. So, satellites and the GPS system within the cell phone are two basic necessities for successful GPS tracking.
