What's the difference between Apple's 5s2g network and 4g network?

The difference between Apple's 5s2g network and 4g network;

1: 2G network refers to the second generation wireless cellular telephone communication protocol, represented by the digitalization of wireless communication, which can carry out narrowband data communication. Common 2G wireless communication protocols are GSM frequency division multiple access (GPRS and EDGE and CDMA 1X code division multiple access), and the transmission speed is very slow.

2:4G network refers to the fourth generation wireless cellular telephone communication protocol, which is a technical product combining 3G and WLAN. It can transmit high-quality video images, and the image transmission quality is equivalent to that of HDTV. The download speed of 4G system can reach 100Mbps, which is 2000 times faster than dial-up Internet access, and the upload speed can reach 20Mbps, which can meet the requirements of almost all users for wireless services.

The difference between the two: the 4G network is faster and the call quality is better.
