What are the characteristics of single and dual-band wireless APs and their respective characteristics?

There are many kinds of wireless bridges in the market, but they are inseparable from single-frequency and dual-band. Some people think that dual-band is good, not only “tall”, but also the wireless signal is good. Is this really true?
This is like the situation of low-end cars and high-end cars. Low-end cars are not as good as high-end cars in hardware, but they are cheap and are the first choice for many people. Although high-end vehicles have good materials, they are more expensive and not necessarily cost-effective. If they are not "rich people," few people choose.
Similarly, single-frequency wireless bridges and dual-band APs are not good or bad. What kind of feelings are used in the eyes of different groups of people have their own characteristics.
1, different communication standards
Generally, dual-band wireless APs support both 802.11n and 802.11ac protocols, and single-band only supports 802.11n protocols. Therefore, in the case of digital hard-supporting 802.11ac, two WIFIs can be searched.
2, different working frequency bands
Single-frequency AP frequency range of 2.400-2.4835GHz, referred to as 2.4G. The radio frequency band (5150 MHz - 5825 MHz) used by 5G in dual frequency is abbreviated as 5G.
3, the transmission speed is different
The actual transmission rate of the 2.4G wireless AP is between 150Mbps and 450Mbps, while the entry speed of the 5G Wi-Fi is 450Mbps, and generally it can reach over 900Mbps.
4, different anti-interference ability
The 2.4G band is too common and common, so there is more signal interference. The 5G band is relatively clean compared to the 2.4G band and is not easily disturbed in a short time. However, it needs to be understood that the 5G wireless AP has a high requirement for the environment and does not have the ability to diffract and penetrate the wall.

5, the price is different
Relatively speaking, the price of dual-band APs in the market is higher than that of single-band APs. That is, 2.4G APs are cheaper. They are cost-conscious in the commercial environment, but due to their poor anti-interference ability, they are generally used outdoors. 5G wireless AP. However, from the point of view of the development trend of APs, the future of dual-band APs is the mainstream, and as far as the cost permits, it can be selected as much as possible.
In general, a 2.4G wireless AP is sufficient if there is a limited budget and you need to go through the wall, or if the wireless requirements are not high, or where low-density access is required. If you have a budget and high density access, advise you to use dual-band.
Lean technology equipment also has 5G of 2.4G. More popular is the 5G wireless bridge. And the technology is already very mature, and it can achieve 1-100 kilometers transmission in an open environment. If you have a bad grasp of the equipment selection, you can directly contact the staff of Leian.
