GPRS in layman’s terms will be the 2G network we used to use, from 2G to 3G, into 4G, and in 2019 there is already 5G. before mobile phones were smartphones, the most common then was the 2G network, when traffic was cheap. Calls were cheap for short distances and expensive for long distances. Here we explain what GPRS is in professional terms.
Introduction to GPRS
The full name of GPRS is (General Packet Radio Service), GPRS is the abbreviation of the full name of the English language, and the Chinese name of GPRS is “General Packet Radio Service”. It is a kind of evolutionary upgrade based on the previous GSM technology. It has an end-to-end, wide-area wireless IP connection.
Compared with the former GSM’s dial-up circuit-switched data transmission, GPRS is a packet-switched technology. GPRS is a packet-switching technology with “real-time online”, “per-volume billing”, “fast login”, “high-speed transmission”, “free switching”, and “free switching”. The advantages of “free switching”.
It can be simply understood that GPRS is a high-speed data processing technology, which is better than GSM!
The theoretical bandwidth of GPRS is up to 171.2kb/s, and the actual application bandwidth is about 40~100kb/s.TCP/IP connection is provided on this channel, which can be used for Internet connection, data transfer and other applications. So our mobile phones can access the Internet through GPRS.
Similarly in the early IoT applications, DTUs also use GPRS for data transmission. the DTUs will collect the serial data and send the data to the Internet network through the GPRS network of the operator, and then send it to the customer’s server.
