The simplest difference is in the network speed, and the more diverse applications and scope of application that come with the faster speed;
1. 3G is the third-generation mobile communication technology (3rd-generation, 3G), which refers to cellular mobile communication technology that supports high-speed data transmission. 3G service can transmit voice and data information at the same time, and the rate is generally above several hundred kbps. There are currently four standards for 3G: CDMA2000, WCDMA, TD-SCDMA, WiMAX;
2. 4G is the abbreviation for fourth-generation mobile communication and its technology. Compared with 3G, 4G has a higher bandwidth and can transmit higher-quality videos and images. In fact, the LTE system used by 4G can directly cut voice data into packets for transmission due to the high data transmission rate; in the 4G era, thanks to the higher transmission speed, streaming media and live broadcast have become common usage scenarios;
3. The 5G network will have larger capacity and faster data processing speed, and it will become possible to launch more new services through mobile phones, wearable devices and other networking hardware. The capacity of 5G is expected to be 1,000 times that of 4G. With 4G network, you can't really play games online in real time on your mobile phone, but you can do it with 5G network. The 4G network is built specifically for mobile phones and is not optimized for the Internet of Things. 5G technology provides ultra-large bandwidth for the Internet of Things. Compared with 4G, 5G networks can support more than 10 times the number of devices;
The above is the specific introduction of the difference between 3G, 4G and 5G, I hope it can help everyone.
