Remember that in the past, you used a network cable to connect to the computer to access the Internet. If you want to use a mobile phone to access the Internet, you must use the mobile phone's own data, which is not only very inconvenient, but also a waste of data. Later, with the use of wireless routers, a wireless router can be used at home, so that both computers and mobile phones can be connected to the Internet, which is very convenient. Although wireless routers are very convenient to use in a home environment, some large enterprises, hotels, guesthouses, and KTVs have found that using wireless routers does not work. The first is that the coverage distance is too short, and it is impossible to connect to the network after a certain distance. This time, the speed is very slow, and it can't meet the basic Internet needs at all. Later, a wireless ceiling AP was introduced. The ceiling mounting AP can be said to be the savior of commercial wireless network coverage. It not only has a long transmission distance, a wide coverage, and a very fast speed, even if 10 people go online at the same time, there is no problem. With the development and application of PoE power supply technology in recent years, wireless APs have also continued to improve in this direction, and they have gradually withdrawn from wireless APs that support PoE power supply. For example, SunSoont's ceiling AP series support PoE power supply, which provides power to ceiling APs. There is one more choice in the way. Nowadays, many places that create wireless network coverage have begun to use PoE switches to power APs. Let's see what benefits it has. When performing wireless coverage, using PoE switches for power supply can greatly reduce construction difficulty and construction costs. There is no need to think about how to route the power cord, and after using the PoE switch for power supply, the wireless ceiling AP can be installed anywhere without restrictions. Supplying power to the ceiling AP through the PoE switch is not only flexible in deployment and methods, reducing construction costs, but also reducing construction time, and later management is also very convenient. It can be said that if you build a wireless network and still use traditional power supply, you are really out, so hurry up and use a PoE switch to power supply.
