What are 5ghz and 2.4ghz

5ghz and 2.4ghz refer to the working frequency band of wireless routers. 2.4GHZ is the most commonly used wireless frequency band. It has wider coverage and stronger wall penetration performance, but it is easily susceptible to interference. 5GHz is a high-frequency channel band with large bandwidth and good stability, but its wall penetration capability is weaker than 2.4GHz.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

5ghz and 2.4ghz refer to the working frequency band of the wireless router. 2.4GWiFi refers to the wireless frequency of 2.4GHz-2.5GHz, and 5GWiFi refers to the wireless frequency of 4.9GHz-5.9GHz.

2.4GHZ is our most commonly used WiFi frequency band. It has wider coverage and stronger wall penetration performance, but most of the wireless devices in daily life are in this frequency band. So it’s easy to get interrupted, and the internet speed isn’t that fast.

5GHz is a high-frequency channel band with large bandwidth and good stability. It is not easy to drop when multiple peripherals are connected, but its wall penetration capability is weaker than 2.4GHz. The 2.4GHz frequency band has good wall penetration performance, but the bandwidth is relatively narrow, and it is easy to drop out when multiple peripherals are connected. Dual-band wireless routers work in 2.4GHz and 5GHz modes at the same time, while single-band wireless routers can only be used in 2.4GHz mode.

At this stage, electronic products mostly use the 2.4GHz frequency band. Generally, mobile phones and wireless network cards basically support 2.4GHz. Since there are many devices using 2.4GHz, it is easy to cause interference. 5GHz refers to the WiFi frequency band. There are few devices in the current environment and there is relatively little interference.
