Some time ago, I did a wireless coverage project in a hotel. Recently, I sorted out the pictures and took them out to share. I used to do network engineering and used TP panel, but later I found that there would be interference if I used too much. I inquired about the wireless coverage of the hotel on the Internet, and chose the simplest one with moderate price among several schemes. It is found that the so-called antenna-fed coverage is more professional, that is, the ceiling antenna + feeder is connected to the wireless AP, and an AP tap with multiple ceiling antennas are installed in the aisle to cover and penetrate the rooms on both sides.

The installation of the sky-feed cover is relatively simple, it is installed in the aisle, it does not need to be used in every room, and the installation of the suction roof in the aisle looks very beautiful. Finally, it is found that China Mobile and China Unicom also install ceiling antennas in the corridor. OK, no longer shiver, first the above picture, draw a simple sketch, two L-shaped channels, each layer I used 2 AP installed 6 ceiling antennas to complete.

Just received a quick delivery of equipment, first take a picture, 2 industrial-grade wireless AP, high-power fat AP, the signal is very powerful, tap 4-8 ceiling antenna is no problem, there are ceiling antenna and finished feed line, you can save time to do the joint. The tool is almost the tool for the network cable clamp to make the crystal head, which is similar to the previous network wiring project, which can connect the switch and do the crystal head.

Wireless AP and ceiling antenna to take a close-up, mobile phone photos, general definition, make do with it first.

Of course, there is also an important tool, the network debugging notebook computer is indispensable, the configuration is not high speed, the so-called sharpening knife does not miss the firewood, usually have time to do a little better Windows system, testing and debugging can save a lot of time. The basic skills of a network management.

Ready to start, before starting to remind everyone here, have time to test the equipment in the company or the computer room, so as not to install it, and take it down to check the equipment. In addition, if you have time, it is best to use a feeder to connect the wireless AP and the ceiling antenna on the ground before digging holes in the ceiling, and then go to each room to roughly test the wireless signal, so as not to dig holes all over the ceiling of the hotel.

Ran to the location of the writing desk and bedside in the room to test the signal of each guest room, it seems that the signal is not bad. Installation can begin now, because many hotel ceilings are made of plasterboard, so it is easy to drill holes with scissors and tighten the ceiling antenna completely to the ceiling. After installing it, it doesn't look very generous and beautiful.

The hotel site under decoration construction is messy and messy. Finally, I finished my work, went to the bedside and writing desk in the room to test the signal strength, climbed up and down, ran upstairs and downstairs, and earned hard money.

Wireless signal strength is as measurable as sound and can be measured with WirelessMon software installed on a laptop. Wireless signal testing software WirelessMon must learn to use, the following is a screenshot of wireless signal testing software WirelessMon.

In order to compare the effect, you can mark the received signal value of each room test on the room sketch, so that you can clearly see that those rooms are qualified and those rooms are not qualified. The signal has something to do with the wall and the room layout, this time the signal is very good, the hotel is also very satisfied.

Finally, two additional points are made:

1. Interference problem:

It is the same frequency interference, which is very important. There are too many AP and it is troublesome to interfere with each other, especially when there are too many users. Wireless people all know that without co-channel interference, the network delay and packet loss are very small, even if the signal is very weak, it can still connect stably. In short, we must reduce the number of AP, plan and deal with the problem of co-channel interference, and get twice the result with half the effort.

2. Broadband problems:

Can apply for multiple broadband overlay, enterprise optical fiber is too expensive not cost-effective, 20m household can, 100m will not really have 100m to you, about 800 yuan / year. If the broadband quality is good and the Internet speed is fast, the impression of the wireless coverage project will be much better. In short, broadband is very important, be sure to apply for more.
