The difference between 4g wireless router dual frequency and sin

Due to the limitation of 2.4G frequency, the speed of single-frequency routing has reached the ceiling, and dual-frequency routers have gradually become the standard configuration in the mainstream market. Dual-band router refers to a router that can work on both 2.4G and 5G channels at the same time, and has stronger anti-interference performance.

1. Communication standard

Dual frequency is 802.11n and 802.11ac, while single frequency is only 802.11n. So when the digital hardware supports 802.11ac, two WIFIs can be searched.

2. Working frequency

The frequency range of the single-frequency router frequency band is 2.400-2.4835GHz, referred to as 2.4G, the radio frequency used by 5G in dual-band (5150MHz-5825MHz), referred to as 5G.

3. Transfer speed  

The actual transmission rate of the 802.11n wireless router is between 75Mbps and 150Mbps.

The entry-level speed of 5G Wi-Fi is 433Mbps.

4. The 5G frequency band is cleaner than the 2.4G frequency band, and it is not easy to be interfered in a short time.

1). Currently 85% of Wi-Fi clients are 2.4G;

2). The 5G frequency band has high frequency, strong attenuation, and the transmission distance is not as far as 2.4G, especially the wall penetration performance;

3). Because of the high frequency and high requirements of RF circuit components, it is difficult to adjust the indicators to excellent.

5. The price

It is equivalent to say that the current dual-frequency price is still high for ordinary flats, while the single-frequency price is low, but the future dual-frequency is the development trend.
