With the rapid development of information technology and the universal popularity of Internet technology. The ability and speed of people to process and exchange all kinds of information has been greatly improved, and it is time to update as a auto gps tracker. At present, auto gps tracker using 3G modules are rare. The cost of 3G is higher. The common ones are 2G modules auto gps tracker, but 3G cards and 4G cards can be used.
So what is the 3G auto gps tracker? It is a 3G module used in the designated device to use the 3G network to transmit data on the network. Compared with the 2G module, the cost is high, but the transmission speed is fast and the positioning speed is fast.
Some friends have to ask, since the 2G network can use the auto gps tracker, is it necessary to develop a 3G auto gps tracker?
The answer is yes. As early as two years ago, China Unicom and China Mobile-led operators have begun planning to shut down 2G networks. After the technology changes of 3G and 4G generations, the 2G network that has been in operation for more than ten years has become a heavy economic burden for the three operators. As we all know, compared to 3G and 4G networks, 2G network tariffs are very low, and some packages are as low as 3 yuan. For China Mobile and China Unicom, the 3-yuan card is everywhere in every region of the country. In terms of operating costs, the cost of 2G networks and 4G networks is almost the same. In addition, the 2G network base station technology is relatively old, and the energy consumption is high. The three operators have the most 2G users, and the least money is made. In some areas, the 2G network runs even at a loss. More importantly, the high-quality frequency used by 2G continues to be used, resulting in a significant increase in the cost of 4G network construction for the three major operators. This is the real reason for shutting down the 2G network.
In foreign countries, AT&T, Bell, Telus, Singapore, Australia and other operators in the United States have shut down 2G networks.
In order to adapt to changes in the market, the auto gps tracker naturally develops to 3G and 4G.
