Summary of wireless network wiring principles and methods!

Select the location of the wireless AP

For wireless networks, the placement of wireless APs is very important. Since the coverage of wireless APs is very limited, and as the distance increases, the wireless signal will become weaker and weaker, the anti-interference ability will become worse and worse, and the wireless transmission rate will also become lower and lower. Therefore, choosing a good placement can not only ensure that the wireless network can cover every corner, but also ensure a higher transmission rate.

When choosing a wireless AP access location, you should pay attention to the following issues.

• ***, place it at a high place. Wireless signals propagate in a straight line. Every time they encounter an obstacle, the wireless signal will be attenuated. The higher the wireless AP is placed, the less likely and frequent it will be blocked, and the better the signal strength can be guaranteed. If the ceiling in the living room is hollow, the wireless AP can be hidden in it, which is both beautiful and ensures the corresponding height of the AP.
• Second, place it in the center. The coverage of the wireless signal is a circular area. Therefore, only by placing the wireless AP in the center can we ensure that all bedrooms and living rooms are within the coverage area.
• Third, pass through the least number of walls. Experiments show that after passing through two brick walls, the signal strength will be weakened by 20%, but the original transmission rate can still be guaranteed; but if it passes through the wall three times, the signal strength will be weakened by 50% to 60%, and the transmission rate will also be reduced to 30% to 40% of the original rate.
• Fourth, the location is hidden. After the wireless AP is configured and installed, it can be managed remotely by software. Therefore, for the sake of aesthetics, the wireless AP can be placed in a relatively hidden place.
• Fifth, dry and ventilated. As an electronic product, the wireless AP should be protected from sunlight, baking, rain and moisture, so it can be placed in a dry and ventilated place to facilitate heat dissipation and ensure normal operation.
• Sixth, independent power supply. The wireless AP should use the same power supply as the computer, and avoid using the same circuit as air conditioners, refrigerators, washing machines and other appliances to ensure that it is not interfered with and affected by pulse current.

Wireless AP room design

According to the living room, there are roughly the following options.

1. Two-bedroom apartment

Since the effective transmission distance of wireless AP in a closed environment can reach 30m to 50m, even if there is a brick wall blocking it, it is more than enough to use only one wireless AP in a two-bedroom room. If the ceiling in the living room is hollow, the wireless AP can be hidden in it, which is both beautiful and ensures the corresponding height of the AP. The wireless AP can also be placed near one end of the bedroom, or hidden in the coffee table or TV cabinet in the living room.

If the community provides broadband access, a twisted pair cable should be laid from the information socket to the wireless AP to connect the home network to the community. If ADSL is used to share Internet access, a twisted pair cable should be laid near the telephone socket to connect the wireless AP to the ADSL Modem.

2. Three-bedroom apartment

The design of the wireless network for a three-bedroom apartment is basically the same as that for a two-bedroom apartment. It is best to place the wireless AP in the ceiling of the living room. If it cannot be placed in the living room, it should be placed in the middle room so that the wireless AP only needs to pass through a brick wall to reach each room, thus ensuring the strength of the wireless signal and the transmission rate of the network.

3. Duplex

Unlike ordinary brick walls, poured cement floors will cause a significant attenuation of wireless signals, so a wireless AP should be set up on each floor and two wireless APs should be connected together with the help of a hub. In other words, a duplex room must be wired in an integrated manner to achieve connections between wireless APs and between wireless APs and the community broadband.

The wireless AP in the lobby on the first floor can be placed in the center of the ceiling to ensure that the entire lobby is covered by a strong signal. Of course, it can also be placed near the window to ensure that the indoor signal strength is certain and that the laptop can still access the home network when it is outdoors. If there are three bedrooms on the second floor, it can be placed in the middle bedroom; if there are two bedrooms, it can be placed in a hidden position near the wall of the other bedroom.
