Is the wireless bridge a microwave transmission? What is the difference between them? Let's talk about it together!
The wireless bridge transmits signals through electromagnetic waves. It has two frequencies of 2.4G and 5.8G, and operates in the frequency bands of 2312~2732MHz and 4920~6085MHz respectively. Wireless microwave is a kind of wireless electromagnetic wave with a frequency range between 300MHz and 300GHz.
From this we can see that the wireless bridge is also within the frequency range of the microwave, and the wireless microwave includes the frequency of the wireless bridge. It is said that the wireless bridge is also a kind of microwave transmission.
The difference between the wireless bridge and the wireless microwave is summarized in detail as follows:
1. The frequency is different. The frequency of the wireless bridge is 2.4G and 5.8G, while the frequency range of the microwave is very wide, between 300MHz and 300GHz.
2. The transmission distance is different. It is precisely because of the low frequency of the wireless bridge, the transmission distance is relatively short, generally from 1 km to 10 km; while the microwave has a wide frequency and the transmission distance is very far, ranging from tens of kilometers to one hundred kilometers.
3. Diffraction function is different, the diffraction function of bridge transmission is strong, and the diffraction function of microwave transmission is basically not, because the higher the frequency, the weaker the diffraction. Diffraction is diffraction, which refers to the physical phenomenon that the wave deviates from the original straight line when the wave encounters an obstacle. When the wireless signal encounters an obstacle when the bridge is transmitted, it will bend and propagate. For example, if you put a wireless bridge in one room, you can receive a signal in another room, and the signal is only weakened.
4, the role is different, the wireless bridge can be used as a wireless AP, but also can transmit video, audio and data signals, while microwave transmission can only transmit video, audio and data signals, can not be used as an AP.
