Compared 2.4G wifi and 5G wifi
The 2.4G and 5G mentioned in WIFI refer to the frequency band being G Hz. 2.4G is a wireless technology. Because its frequency band is between 2.400GHz and 2.4835GHz, it is referred to as 2.4G wireless technology. 2.4G WiFi refers to the technical standard based on IEEE 802.11b, and IEEE 802.11b is based on the IEEE802.11 series standard products of 2.4G Hz frequency band. 5G WiFi refers to the wireless technology developed based on the IEEE 802.11ac standard. Because the IEEE 802.11ac technology itself works in the 5G Hz frequency band, it is also called 5G WiFi.
Since 2.4G wifi and 5G wifi work in different frequency bands and are based on different standards, they have their own advantages and disadvantages.
2.4G WIFI advantages:
The signal is better than 5GWIFI. 2.4Gwifi works in the 2.4G frequency band. According to the physical characteristics of electromagnetic waves, the longer the wavelength, the less the attenuation. The frequency of 2.4GWIFI is low and the wavelength is longer. Far. Disadvantages of 2.4GWIFI: 2.4G signal bandwidth is relatively narrow, home appliances and wireless devices mostly use 2.4G frequency band, the wireless environment is more crowded, and interference is greater.
5G WIFI advantages:
5G signal bandwidth is wider, the wireless environment is relatively clean, there is less interference, the network speed is stable, and 5G can support higher wireless speed; 5GWIFI disadvantages: 5G signal frequency is higher, and the attenuation is greater when it spreads in the air or obstacles. The coverage distance is generally shorter than 2.4G signal.
From the above advantages and disadvantages of 2.4GWIFI and 5GWIFI, it can be seen that the two are almost complementary. The signal of 2.4GWIFI is good but the bandwidth is smaller than that of 5GWIFI. Therefore, it is strongly recommended that when choosing a wireless router, try to choose a dual-band wireless router, so that you can take into account the advantages and disadvantages of 2.4GWIFI and 5GWIFI at the same time.
