The Difference between GSM and GPRS

The Difference between GSM and GPRS

1.GSM is the abbreviation of Global System for Mobile Communications.

2.GPRS is the abbreviation of General Packet Radio Service.

3.GPRS is a packet data bearer and transmission service developed on the basis of the GSM system.

4.The most fundamental difference between GPRS and GSM system is that GSM is a circuit switching system, and GPRS is a packet switching system.

5.GSM can only use SMS to transmit data, and it can't be "real-time online" or "charged by volume". Compared with GSM, GPRS has obvious advantages in the bearer and support of data services, and it can more efficiently use wireless network channel resources, it is especially suitable for intermittent, acyclic data transmission, a small amount of data transmission, and infrequent transmission of large capacity data.

The technical advantages of GPRS are also manifested in the following aspects: high transmission rate; high resource utilization; short access time; always online; support IP protocol and X.25 protocol; reasonable charges.

6.Advantages of GPRS:

GPRS communication costs are low

GPRS data transmission is fast, real-time performance is good

GPRS is a networked data transmission that can operate multiple devices simultaneously

There is no communication module in the center, and it can be directly connected to the Internet. The operation cost of the center is fixed, and the data traffic speed is far greater than the GSM mode.
