Wireless network coverage scheme on the fifth floor of small hotels

1.？ Suppose all the rooms in the hotel have the same orientation. Consider persuading people on the third (fourth) floor opposite the hotel (the distance from the hotel should not exceed 80 meters as far as possible) to install the wireless router in the window on the third floor opposite the hotel (in order not to pull the network cable, put the existing wireless router in the intervisibility part between the hotel and the opposite wireless router, and set the wireless access point mode locally (access? Point or ap), set the repeater mode on the opposite side (see the figure below), and try to choose a high-power router (covering at least 300 meters outdoors and 30 meters indoors), such as TP-LINK? TL-WR340G+,1around 20 yuan! In this case, the signal can enter all rooms from the opposite window unimpeded, and can only be reflected on the ceiling or side wall in the room once at most to reach the receiving computer. Because there is no shelter, the signal attenuation is very small, which should meet the requirements of the landlord.

2.？ Assume that the guest room faces north and south (that is, different orientations). According to my experience, if the wireless router is placed in the guest room, it can serve the guest room on the upper and lower floors and the two adjacent rooms on the left and right, which means that the signal can easily penetrate the two concrete walls and floors. (Note that the capacity of high-power wireless routers is limited. If it is far away, although the signal of the wireless router is strong enough, the signal of the computer wireless network card may not reach the wireless router after penetrating the obstacle, so try to avoid setting the wireless router in the case of obstacles. Landlords can arrange their own wireless routers according to this principle. If there are many partitions, it is recommended to arrange them in the center of each floor. Then all wireless routers are connected to ADSL routers in a centralized way. If the interface on the router is not enough, connect it to the switch, and then the switch is connected to the ADSL router.

It is worth noting that the angle of the omnidirectional antenna of the wireless router is also very important. Please look at the radiation pattern of omnidirectional antenna signal (/pages/imageuploadfolder/2009817155035235.jpg), so the antenna angle should be adjusted as needed (generally, when the antenna is upright, the reception effect is better in the horizontal plane, but it will be weaker up and down).

As the landlord runs the hotel, guests should check the rooms before leaving. Why are they afraid that the wireless router will be stolen? Of course, just in case, you can consider making a box with a lock, locking the wireless router and power socket in the box, but the antenna should be exposed outside the box. In order to prevent the antenna from being stolen, you can stick the antenna with 502 glue. Of course, there are also many products whose antennas are not detachable and unnecessary.

In addition, I feel that the concept of routers, switches and wireless access points is not very deep. ADSL routers are used to connect to the Internet, switches are used to tap users or other LAN devices (such as wireless access points), and wireless access points are used to tap wireless users (which can be understood as wireless switches). There are many wireless access points in the market that integrate the functions of ADSL modems and routers, so they are called wireless routers.
