I. Residential Cabling Scheme

1. Two-bedroom household wiring

The master bedroom is equipped with two information points, which are located on both sides of the double bed, so that both sides can use the laptop at the same time. The auxiliary bedroom is equipped with information points, which are located near the bedside or desk of a single bed and are convenient for children or visitors to use. An information point is installed in the living room, which is located at the end of the sofa or near the tea table. It is convenient to use a laptop computer in the living room for office or entertainment.

In addition, a twisted pair is introduced from the information socket provided by the residential area to the hub equipment to realize the access of the local area network in the residential area of the home network. Telephone lines and power lines should be laid separately, with a distance of 20 cm. The distance between information socket, voice socket and power socket should also be 20 cm. The wiring scheme can be referred to the design as shown in the figure, where "." Represents information points.

The twisted pair is inserted into the PVC pipe and embedded in the floor cushion. When you need to cross the wall, drill holes near the ground. The information socket is wall-shaped and the bottom box is embedded in the wall. The distance between the information socket and the ground is 20 cm, and the distance between the information socket and the power socket is 20 cm. Hubs (hubs or switches) are installed in auxiliary bedrooms. Five desktop devices are recommended, which can be fixed on the side near the bedside of the desk* to save space and ensure proper ventilation space, while avoiding direct exposure of the equipment and affecting the beauty.

2. Three-bedroom household wiring

The two bedrooms are the same, so I will not repeat them. Because the living room of the three-bedroom is usually large, it can be considered to install an information point on the walls on both sides, which is located in a concealed position 1 m to 1.5 m away from the window, so it is convenient to access the computer at the same time. The requirement of integrated wiring is exactly the same as that of two-bedroom cabling. The wiring mode of the three-bedroom is the same as that of the two-bedroom. Pay attention to it. Represents information points.

3. Duplex Home Wiring

The design of the main bedroom and auxiliary bedroom upstairs, as well as the broadband links of the residential area, are the same as those of the two bedrooms. Two information points are installed on the walls on both sides of the first floor lobby. They are located in the concealed position between 1 m and 1.5 m from the window. It is convenient to access the computer or wireless AP at the same time, drill holes in the floor and the wall and penetrate the PVC pipe, so as to realize the crossing of twisted pairs between the floor and the living room. It is suggested that the hubs should be installed on the back of a staircase, which is easy to maintain and does not affect the beauty. The requirement of comprehensive wiring is exactly the same as that of two-bedroom, in which "." Represents information points.

If Cell Broadband allows multiple users to access each home and DHCP is used to dynamically allocate IP addresses, then only one crossing line is needed to connect the hub to the information socket provided by the cell. If DHCP service is not provided in the cell, IP address should be set for each computer. If the cell allocates only one IP address for each family and restricts the number of access by MAC address, broadband routers or proxy servers must be used. When broadband router is adopted, a cross twisted pair is used to connect the WLAN port of router and the information socket of cell, and another cross line is used to connect the LAN port of router and the household hub equipment. When using proxy server mode, if using ICS of Windows, two network cards are needed, one network card is used to connect the cell and one network card is used to connect the cell and the other is used to connect the household hub equipment. Block network card connects home network.
