How to arrange WiFi in the "big house"?

Now there are many rich people, buying big houses, living in big houses... But does the wifi coverage of the house have to keep up with the size of the apartment?

Written in the front: As soon as you enter the digital topic, you will bring your own traffic to attract a group of levers, with a half-understanding of the "knowledge" to leverage with you, the reason is also because digital products are currently the cheapest category of goods, so everyone in the digital field can often find more "same good", and even a group of liberal arts bloggers are also opening digital content... So what the lever said is correct, and iN does not make any rebuttals.

Now the centralized problem is how to arrange wiFi in the "big apartment" house to let everyone go online without cards. So what is the concept of a large apartment? In fact, the large apartment type that iN thinks is like this:

Hundreds of millions or even billions of mansions, compared to such a large apartment, everyone's house is counted as a snail dwelling, right? But even such a large-scale house is actually much less difficult to arrange WiFi than such a building:

There is nothing logically wrong with that, right? No matter how large the apartment type is, it is difficult to be stronger than the Demand for WiFi coverage required by a shopping mall, whether it is from the number of points or the demand on the access device "home" is always a negligible WiFi use place. The "large apartment" of 2 or 300 square meters is actually nothing in front of the WiFi solution. Wireless standards can achieve a completely smooth connection of wireless devices in a building area of tens of thousands of square meters. How can it not work when you get home? The reason is simple, everyone is pitted! The reason for the pit is also super simple – the consumer picture is cheap.

If you first understand the principle of the wireless solution, you can know that you are not wronged by the pit. Let's take a look at the wireless design solution:

The original purpose of the wireless solution is to allow the device to be connected to the Ethernet through a radio signal into a technology, which uses a device called an AP such as the small box that emits radio signals in the figure above is the AP. An AP (Access Point) is simply a bridge that "rides" the signal of a wireless network into a wired network. This bridge has only one signal conversion function, and more control functions are handled by the AC (Wireless Access Point Controller) in the upper left corner of the figure above. These devices are then uniformly connected to the switch to the LAN, and then to the Internet through the router.

A minimized wireless network is also a large number of devices like this:

Moreover, the design of the AP did not emphasize that one AP could cover all areas.

But consumers have bought this kind of thing for cheap:

This thing is called "wireless router", which simply means that a large number of devices we mentioned earlier are concentrated in one device, which includes routers, switches, wireless controllers and wireless access points. iN dares to say that 90% of people are now using wireless routers, and more than 99% of people have bought such wireless routers.

Why? This is cheap. Whether it is in terms of price or deployment cost, this thing is super invincible cheap, dozens of dollars can solve the problem of tens of thousands of dollars, who uses who will say that it is not fragrant?

But why do you want to say that people's functions are not good and the coverage rate is not enough? Is it because you want to eat the taste of French food?

Can you understand the problem of "wotou ≠ french food", just continue to see, why can a wireless router of tens of dollars generally do tens of thousands or even hundreds of thousands of professional network equipment? Wifi standard is a set of data formats specified by the IEEE joint manufacturers, you can send and receive radio pulse signals according to a specific data format to complete the IEEE standard requirements, and you can connect with devices that meet IEEE standards. But this is only connected does not mean that you can use it well, nor does it mean that everyone can use it in a mansion.

And note that there is a line of Certified below the WiFi logo above, which means "authentication", and now even many miscellaneous WiFi routers do not have this logo printed on them, that is to say, they have not passed the certification of the WiFi Technology Alliance at all. This is even less a guarantee that they will work properly.

For the kind of routers with a lot of antennas like spiders and the kind of "king-of-the-wall" routers, they are basically not the things that iN recommends. Wireless network antennas can be built-in, do not have to exaggerate the prominence; the so-called wall king is almost 100% of the false standard, because the country has a limit of 100mW transmission power of wireless equipment, and even the national regulations dare to violate the products You dare to buy? If there is no violation of state regulations, then how can it be different from other families?

Well, to the practical stage:

First of all, you should not only look at the signal strength, wireless signal survey has many indicators, such as iN, the new home Huawei came to do when it came out of such a set of figures:

2.4>5G field strength planning simulation diagram

2.4>5G weak field strength simulation diagram

2.4>5G physical layer throughput simulation graph

2.4>5G signal-to-noise ratio simulation diagram

2.4>5G application layer throughput simulation graph

The most important of these graphs is the 2.5 & 5G application layer throughput simulation graph, which allows you to query the expected value of the network throughput of your mobile phone, tablet and other devices in a certain location. In fact, if you look at the picture, you can see that a 100-square-meter house is enough to put an AP in a reasonable position.

If there is a larger area, then multiple APs can also be placed, as for Mesh, what did we say earlier? This is also a simplified device, if possible or the AC-AP model is more reliable, so the iN is not considered.

If you can't get a professional team, you can find software similar to NetSpot Wi-Fi to install your own floor plan to plan and simulate.

Or simply ask your network engineering team for specialized software like Wlan Planner to figure out your network planning solution.

If not, find a WiFi analyzer installed in the Android phone, and then place a WiFi access point or router in the expected WiFi placement location, and run around the whole house to measure the WiFi signal strength of each point.

There's a misunderstanding here, do you really need to cover the whole house without dead ends? This is not the case. When you have a room plan, you should first plan where you want to put the devices that need to be connected to WiFi, where you need to work and play, and what type of equipment you will use in which area, at this time, you only need to cover the location that you expect to cover in the process of calculation.

For example, the location of iN's studio: it is expected to put two desktops, which are working nodes, but do not require WiFi at all.

Isn't it nice to put 2 10G fibers directly on the work desk? Do I have to use WiFi?

On the contrary, the living room is often the location where guests come to visit, so the signal of WiFi in this area is to be guaranteed, and all guests cannot be required to bring their own network cables, right?

So in the living room there is also a RiHomeGuest access point dedicated to guests, this access point uses Vlan technology and the main network at home is isolated, providing only basic Internet access functions.

The real main AP hangs on the original map.

This is a commercial APs of Huawei that provide WiFi6 access. Basically, the indoor area of more than 100 square meters is fully covered by This WiFi is also covered. At the same time, there is also an AP that is very cheap for guests to use, and will be placed in the equipment room (sorry this location has not been cleaned).

There is also a piece of advice, that is, you can use the ceiling AP as much as possible not to use the 86 panel AP, this thing is not recommended in any way. Manufacturers of this product are reprehensible and do not explain too much.

Tell you a little tip, most people live in the building, this is the problem, your WiFi signal is not good There is also a main reason is that your neighbor's WiFi is too much. In general, channel selection is a skill, to choose a channel that occupies less. Of course, if you are more real like iN, you can do this like iN.

In order to illustrate this problem, iN just took sandpaper to polish the wall of the scene, which is considered to be the blood of this article, right?

After the wall putty is ground off, there is a gray coating, which is magnesium oxide. At the beginning of construction, iN used magnesium oxide to coat the floor, ceiling and wall facing the corridor with a layer of magnesium oxide coating. The role of this paint is to isolate radio signals, which can greatly weaken the influence of the WiFi signal of neighbors on their own homes.

After applying this layer of paint, if you turn on the Channel Evaluation function of the WiFi Analyzer inside the house, you will see this:

But if you go out of the house and go inside the corridor... This is the result of the channel:

Isn't the effect of a thin layer of magnesium oxide coating surprising? In fact, these exposed WiFi signals in your home will also occupy the wireless bandwidth of your AP signal, causing a poor WiFi signal in your home.
