What is GPRS? Answer: GPRS (General Packet Radio Service) is the technology used by GSM Wireless carriers to transport data across their network. By breaking the data up into packets the network can transport the data at fast speeds and reliability. EDGE is an enhanced version of this technology which produces faster download speeds. UMTS (currently deployed in many major US Cities with AT&T) will display even faster speeds for Data transportation for both downloads and uploads utilizing the HSDPA technology.
A GSM GPRS tracker is perhaps the most popular type of GPS data tracker available today. A GSM sim card is inserted into the GPS tracker which allows the device to transmit wireless data through a network (like ATT and T-Mobile) to a wireless access point or APN.The APN connects to the internet and transmits the data to a GPS service providerâs server, where tracking data is made available to the end user.DMA trackers, are a little different than a GPRS GSM tracker. Most CDMA gps trackers are equipped with the gpsOne Qualcomm chipset. When compared to GSM trackers, the gpsOne chipset does not appear to be as accurate as its counterpart.
