What kind of wireless router is generally used in hotels?

This depends on the area and layout of your hotel

Because generally hotels have many rooms and floors. Wireless routing uses 2.4G frequency radio, which is a microwave frequency. Radio at microwave frequencies can only propagate in straight lines, so it is basically impossible to penetrate a building (especially a reinforced concrete structure). Due to radio wave reflection, some signals may be able to bypass obstacles, but the reflection may be unstable and severely attenuated.

Generally, in hotels, a wireless router needs to be installed on each floor to achieve the desired effect, and each router needs to replace the original omnidirectional antenna with a gain directional antenna.

TP-LINK TL-WR941N 3 omnidirectional antennas (replace the 2 omnidirectional antennas with gain directional antennas and keep one), which can be installed in the middle of the corridor. If the area is large and the room has many corners, It can be installed in the corner, replace the omnidirectional antenna with a gain directional antenna, and then point the gain directional antenna in the desired direction.

Specific applications need to be tested and designed according to the specific environment of the hotel.
