2.4G means 2.4GHZ, which means the vibration frequency of the router’s electromagnetic wave. It is also called the operating frequency because the higher the frequency, the shorter the wavelength, so the penetration is poor.
Advantages of 2.4G WiFi: The 2.4G signal frequency is low, the attenuation is smaller when propagating in the air or obstacles, and the propagation distance is farther.
Disadvantages of 2.4G WiFi: 2.4G signal bandwidth is narrow, home appliances, wireless G band, wireless environment is more crowded and interference is greater.
Wi-Fi (pronounced: /ˈwaɪfaɪ/, French pronunciation: /wifi/), also known as "mobile hotspot" in Chinese, is a trademark of the Wi-Fi Alliance manufacturer as a product brand certification , is a wireless LAN technology created in the IEEE 802.11 standard.
