The difference between 2.4g and 5g wifi speeds

With the same bandwidth, especially after the bandwidth exceeds 100M, the 5G frequency band has great advantages over the 2.4G frequency band. As shown in the figure below, my home’s contracted broadband is 300M, using 5G The frequency band can reach a download speed of 316Mbps, while the 2.4G frequency band only has a download speed of 78Mbps, and the network stability (latency, jitter) of the 5G frequency band is better than that of the 2.4G frequency band. What causes such a big difference? Please see below.

Different frequencies, different rates

The carrier of wireless signals is electromagnetic waves. The operating frequency of the 5G frequency band is higher than that of the 2.4G frequency band, which can accommodate more data and load More information, so the rate of the 5G frequency band per unit time is much higher than that of the 2.4G frequency band;

In single-channel mode, the wireless access rate of the 2.4G frequency band The input rate is 72Mbps, and the access rate of the 5G frequency band is 433Mbps, so try to use the 5G frequency band in a space without obstacles.

Signal interference situation

The interference in the 2.4G frequency band is relatively serious. Wireless mice, Bluetooth, and children's toy remote controls all use the 2.4G frequency band, as well as high-power household products. Electrical appliances such as microwave ovens, induction cookers, etc. also use the 2.4G frequency band, and the interference is relatively serious;

Most wireless routers in homes have the 2.4G frequency band enabled. During the peak network usage period at night, dozens of wireless signals can be searched , each wireless channel can only communicate with one device, and it needs to wait for the channel to be idle, causing network speed to decrease and delay to increase. There are relatively few devices in the 5G frequency band, the coverage is relatively small, the frequency band is wider, and there is less interference. Therefore The wireless access rate is faster.

Wall Penetration Ability and Coverage

Electromagnetic waves have such characteristics, the lower the frequency, the longer the wavelength, the stronger the diffraction ability and penetration ability, and the coverage range The wider. Therefore, the wall penetration capability and coverage of the 2.4G frequency band are better than those of the 5G frequency band; the 2.4G frequency band is often used for wireless signal relay and other occasions.
