What is the difference between wireless router 2.4Ghz and 5Ghz?
The difference between 2.4Ghz and 5Ghz wireless router
1. Difference in attributes
The 2.4GHz band has good wall penetration, but the bandwidth is narrow, and it is prone to congestion and dropouts when connecting multiple peripherals.
5.0GHz is a high-frequency channel frequency band, with large bandwidth and good stability. When connecting multiple wireless devices, there will be no channel congestion and peripheral devices will be dropped. The disadvantage is poor wall penetration.
2. Function difference
The 2.4GHz frequency band is relatively common. It is generally supported by mobile phones and wireless network cards. The maximum speed is currently 450m. Because there are many devices using this frequency band, it is susceptible to interference.
5GHz is a wifi frequency band that has emerged in recent years. There are fewer devices using this frequency band and less interference.
Dual-band wireless routers work in both 2.4GHz and 5.0GHz modes, while single-band wireless routers can only work in 2.4GHz mode.
Advantages of 2.4ghz wireless technology
1. Wide range of application
It is a global working frequency band, and the developed products have global versatility. Various wireless products can use this frequency band, which is widely used in indoor occasions such as personal wearable devices and wireless broadband routers.
2. High bandwidth
Its overall bandwidth is better than other ISM frequency bands, which improves the overall data transmission rate, allows the system to coexist, allows two-way transmission, and has strong anti-interference and long transmission distance (short-range wireless technology range).
3. Low power consumption
The antenna of 2.4GHz radio is quite small, and the product is also smaller, which makes the chip more concentrated and reduces power consumption. Due to the advantages of 2.4GHz wireless technology, various manufacturers continue to introduce new technologies, which also make this technology develop rapidly.
Disadvantages of 2.4ghz wireless technology
In order to realize the automatic control of industry, homes and buildings, liberate human beings from the wired environment, with the goal of replacing cables, short-range wireless communication technology standards for wireless personal area network (WPAN, WirelessPersonalAreaNetwork) range have been rapidly Typical technology standards include Bluetooth, ZigBee, wireless USB, and wireless LAN Wi-Fi.
When people enjoy convenient and fast, the electromagnetic compatibility problems of these technologies are increasingly prominent. Because these technologies have selected the 2.4GHz (2.4~2.483GHz) ISM band, coupled with interference sources such as cordless phones and microwave ovens, this band has become increasingly crowded.
