When the hotel does seamless WiFi coverage, do the channels of each AP point need to be staggered?

It's better to stagger, so there will be less interference.

Channel interval frequency band: that is, "channel" is also called channel, which is a data signal transmission channel with wireless signal as transmission medium. IEEE802. 1 1b/g works in the 2.4~2.4835GHz band (China standard), and these bands are divided into 1 1 3 channels. When we release the wireless network, we will choose a frequency band. Theoretically, too many wireless networks in the same frequency band will seriously affect the signal strength. That is to say, if the wireless signal frequency band adopted by the hotel 1F is the same as the wireless signal transmission frequency band of 2F, the wireless network on both floors will be affected to some extent. Besides. There are interference sources near the wireless AP, such as other wireless routes, microwave ovens, mobile phones, Bluetooth devices, wireless speakers, etc. , it will interfere with the normal use of wireless AP. Especially, some digital cordless phones use 2.4GHz frequency band, so it is a good method to change a signal transmission frequency band through wireless AP in the case of unstable network.

In a simple environment with basically no conflict, you can choose any channel. When your wireless network conflicts and overlaps with another wireless network, each wireless network should set a non-overlapping channel: 1, 6 or 1 1 (in Europe, 1, 7, 13). In this way, three wireless networks in the same area have the least interference with each other. If you can't do this, try to choose channels that are far apart.
