What is the difference between 4g and 5g mobile phones?

Difference: 1. The number of frequency bands accepted by 5g mobile phones is higher than that of 4g mobile phones. In addition to 2G GSM and CDMA, 3G EVDO and WCDMA protocols, 5G mobile phones need to support 4G TD-LTE and FDD-LTE. , and also needs to support 5G NR. 2. The number of installed antennas is different. 5G mobile phones have 2 transmitting antennas and 4 receiving antennas; while 4G mobile phones have 1 transmitting antenna and 2 receiving antennas. 3. The configuration of 5G mobile phones has been upgraded, with faster download speeds and greater RAM and storage space.

The operating environment of this tutorial: HarmonyOS 2 system, HONOR V30 mobile phone.

Since 5G network has many new technologies and brings many new features, the baseband that currently supports 4G network cannot support 5G network through software upgrade. So what is the difference between 5g mobile phones and 4g mobile phones? Let’s take a look below.

The difference between 5g mobile phones and 4g mobile phones

1. The number of receiving frequency bands is different

In addition to supporting 2G GSM and CDMA, 3G EVDO and WCDMA protocols, and 4G TD-LTE and FDD-LTE, 5G mobile phones also need to support 5G NR. 5G NR is a global 5G standard based on OFDM's new air interface design. It has the characteristics of high bandwidth, low latency, etc., and 5G NR corresponds to multiple frequency bands, all of which require 5G mobile phones to support.

2. The number of installed antennas is different

5G mobile phones have been changed from the original 1T2R (1 transmitting antenna, 2 receiving antennas) to 2T4R (2 transmitting antennas and 4 receiving antennas);

4G mobile phones are often 1T2R, which means 1 transmitting antenna and 2 receiving antennas. At present, 5G mobile phone terminals require a 2T4R transceiver antenna configuration, that is, 2 transmit antennas and 4 receive antennas.

3. Configuration upgrades

From the perspective of mobile phone configuration, due to the arrival of 5G, the power consumption and network speed of mobile phones will bring a certain improvement. , so the battery capacity and memory capacity will increase in the 5G era.

The high-speed applications used by 5G mobile phones are also a test for the battery of the mobile phone. At this time, mobile phone manufacturers need larger-capacity batteries; due to faster download speeds, 5G mobile phones should be equipped with larger storage. and storage space;

Advantages of 5g mobile phones and 4g mobile phones

## Functional features of 4g mobile phones: From the appearance, 4G mobile phones are really The appearance of the phone is no different from that of common smartphones. Their main features are high resolution, large memory, high clock speed, fast processor, and high-definition camera. 4G phones all have embedded TD-LTE modules.

The main advantage of 5G networks is that data transfer rates are much higher than previous cellular networks, up to 10Gbit/s, which is faster than current wired Internet and 100 times faster than previous 4GLTE cellular networks. Another advantage is lower network latency, less than 1 millisecond, compared to 30-70 milliseconds for 4G.

Advantages of 4g mobile phones: Better compatibility: 4G is compatible with existing 2G, 3G, and 4G networks, and "multi-mode and multi-frequency" has become the standard configuration of 4G mobile phones; the network spectrum is wider: 4G communication theory Reaching 100Mbps transmission, 4G network bandwidth is much higher than 3G network bandwidth.
