Continued from the previous article: How to play smart home – home networking solution selection .

After we have chosen the home networking solution: AC (PoE) + AP. So the question is: how to actually operate, how to wire, and what to consider?

In my case, these factors might be considered:

  1. The position of the weak current box, do you want to move it? What is the best position?
  2. The trend of strong and weak electricity, how not to be affected
  3. Where should our AC be placed and why does AC need POE
  4. Where should our AP be placed and how many
  5. Do you need something similar to a home computer room? Where is it? What’s the use?
  6. How to get the network cable, where to put a few, and what kind of network cable to use
  7. Is it useful to have no fiber in ordinary homes?

Identify needs

Before determining the needs, we determine the current environment:

  1. Telecom broadband currently only reaches gigabit
  2. Most households use WiFi as the main Internet access, and desktop Internet access is less
  3. Do not consider the whole-house optical fiber, the current cost is high (please ignore the local tyrants), there are very few optical fiber devices directly supported, and photoelectric conversion is required
  4. The whole house must be fully covered by the network, and the network must be seamlessly roamed

From the above, we have concluded that the entire house can meet future needs by using Cat6E network cables, and Cat6E network cables can reach 10 Gigabit networks, which can still be satisfied in the future. The whole house is mainly based on WiFi, so when deploying the AP, if the network cable is not required, the network cable is not required to save costs.

What other needs do we need to solve, determine the following information:

  • Whether IPTV is required: Yes, at least one TV is required in the living room
  • Which devices need a network cable: TV, desktop computer, Xbox, AP
  • Whether you need free Internet access: Yes, you will query foreign language materials for a long time
  • Whether to use NAS: Yes, NAS can help store photos, videos, music, etc., and can be called back-end storage for smart homes
  • Do you need a 10 Gigabit network: Yes, the intranet must be fast, at least ensure the speed of accessing the NAS, and video editing needs
  • Do I need intranet penetration: Yes, I need to control my home equipment from outside
  • What is the budget, 4k+

Above, we get:

  1. At least three network cables are required in the living room: TV or TV box, Xbox game console, AP
  2. The study needs at least three network cables: desktop computer, NAS, AP
  3. Each bedroom requires at least one network cable: AP or spare
  4. A 10 Gigabit switch is required to realize 10 Gigabit wired intranet
  5. A set of soft routing, free to surf the Internet
  6. Ask Telecom for a set of IPv4 or external network servers

So based on the above information, I determined that I need a cabinet: put all the network hardware in one place, put the NAS there, and finally put the cabinet in a custom cabinet to hide it perfectly.

Design

The next step is to design the layout plan, which needs to be actually operated according to the floor plan. You can refer to this design drawing of mine:

The basic idea is to have a general network cabinet, the network goes directly from the weak current box to the network cabinet, and all subsequent networks go out of the cabinet. Since the blog mainly achieves intranet penetration, I drew Alibaba Cloud, if you don’t need it, you can not refer to it.

The above figure is only for design reference, and there are some changes in the actual implementation process. Then there is this picture:

The AP in this picture is reduced by one as appropriate, depending on the actual situation.

After you have determined the plan, be sure to check with the electrician as soon as possible to confirm the feasibility of the plan. This is the case for bloggers. It is natural to move the weak current box to the shoe cabinet, and put all the network equipment in the shoe cabinet. Who knows that the strong current and the weak current are on the same vertical plane, which will not work. So it was changed to the dining cabinet, which caught me off guard at the time, and the plan was adjusted and adjusted.

selected device

Based on the above conclusions, the selection of equipment can be started.

cabinet

First, choose a cabinet. The cabinets on tb are also ready-made and very strong. Interested friends can see here:

Simple Open Cabinet

However, if you purchase a cabinet by yourself, you need to consider the location of the cabinet. For example, a shoe cabinet must be of the right size. Also, it is best to call a carpenter to help make a cooling hole out of the cabinet.

The ready-made ones are not enough for me to toss. Based on the principle of geeks, bloggers began to learn from netizens’ purchased parts to assemble the cabinets by themselves. For details, please refer to here:

I fell in love with this configuration at first sight when I saw it on Zhihu, and it was very consistent with my plan. So I also purchased a set, but the heat dissipation is still relatively expensive. Waiting for the house to be remodeled.

Choose AC+AP

Since it is a panel AP, there are fewer options. At first, I fell in love with Huawei’s H6, but this thing was pasted, which is not beautiful enough. So I asked a friend to recommend a TP-Link suit, which saves trouble and worry.

TP-LINK TL-R497GPE-AC PoE ACTP

TP-LINK TL-XAP3002GI-PoE

These two devices, I bought brand new on a certain fish, should not overturn, friends in need can go to a certain fish to search.

This AC is an integrated PoE switch:

  • 9 Gigabit Ethernet ports, 1WAN+8LAN
  • Built-in wireless controller for unified management of TP-LINK AP products
  • All LAN ports support standard PoE power supply, and the output power of the whole machine is up to 120W
  • IPSec/PPTP/L2TP VPN, remote communication is more secure
  • Access authentication (Web authentication, SMS authentication, PPPoE server)
  • Internet behavior management (mobile APP control/desktop application control/website filtering/web page security)

This AP supports Wi-Fi6:

  • Next-Generation Wi-Fi 6 (802.11ax) Technology
  • 11AX 2.4G/5G dual-band concurrent, wireless rate up to 2976Mbps
  • National standard 86 shell, elegant appearance, the thickness of the wall is only 9.4mm
  • 802.3af/at standard PoE network cable power supply, no external power supply required
  • Support TP-LINK easy-to-expand function, simply press the button, you can provide TP-LINK easy-to-expand equipment wireless access
  • Spectrum navigation, guiding dual-band users to connect to the 5GHz frequency band first, balancing the load between the 2.4GHz and 5GHz frequency bands to ensure network performance
  • FIT mode supports automatic RF tuning
  • FIT mode supports intelligent roaming
  • Support weak signal device rejection, prohibit weak signal device access function
  • Fat and thin in one, you can choose different modes according to different application environments
  • Support centralized management of TP-LINK commercial network cloud platform
  • Support TP-LINK business cloud APP remote viewing/management
  • Machine size (mm): 88*86*45.4, wall thickness 9.4mm

The reason why I like this AP is that its wall thickness is only 9.4mm, which is similar to the height of the ordinary socket panel. Perfectly hidden.
