4G is the abbreviation of the fourth generation mobile communication technology. China Mobile 4G adopts TD-LTE in the 4G LTE standard.

Generally, the default for mobile is 4g, and the default for China Unicom and Telecom is LTE. Mobile is td4g network, and China Unicom and Telecom’s fdd 4g network module. This logo can be changed after jailbreaking and is saved in the operation in the configuration file.

LTE introduction

LTE is the abbreviation of Long Term Evolution. The full name should be 3GPP Long Term Evolution. Chinese is generally translated as 3GPP. Long-term evolution technology, which is the 3rd Generation Partnership Project (3GPP) standard, uses "orthogonal frequency division multiplexing" (OFDM) radio frequency reception technology, and diversity antenna technical specifications of 2×2 and 4×4 MIMO.

Supports both FDD (frequency division duplex) and TDD (time division duplex).

In each 5MHz cell, it can accommodate at least 200 dynamic users.

The one-way transmission delay of the user plane is less than 5ms, and the transition time of the control plane from sleep state to active state is less than 50ms.

On December 6, 2010, the International Telecommunications Union officially called LTE 4G.
