Home network system
The common home network architecture is: the optical fiber dedicated line connects the optical cat, and the optical cat connects the router to provide network connection for terminal devices such as mobile phones and computers, that is, the optical cat-router-terminal device.
Light cat
Say "light cat" first. Optical cats are provided by network operators and generally match the bandwidth of home broadband access. If you install 500Mbps broadband, operators will generally support Gigabit optical cats. This is generally no problem.
wireless router
Wireless router is a must-have item for every household, which can realize network enjoyment. The average user will deploy 1 or more wireless broadband routers at home. The WAN port of the router is connected to the optical cat, and the LAN port is connected to the home information socket panel.
But routers also have some little-known tricks. Gigabit optical cats are installed at home, but the router WAN/LAN is 100 Mbps interface, and users can only enjoy the bandwidth of 100Mbps. Similar to a big river, it is a small canal leading to your home. The canal is the reason that determines whether your home is full of water.
The Wi-Fi protocol supported by the router should also be clearly recognized. At present, the most commonly used protocols for Wi-Fi are 802. 1 1n and 802.1/ac. The main difference between them lies in transmission bandwidth and transmission distance.
802. The maximum data transmission rate of110n single spatial stream is 150Mbps. At present, mainstream routers in the market support 2*2MIMO technology, and the data transmission rate is 300Mbps. 802. 1 1ac single spatial stream has a maximum data transmission rate of 433Mbps, and the mainstream router products in the market support 2*2MIMO technology with a data transmission rate of 866Mbps. If you want the router to reach the above theoretical maximum speed, both the router and the mobile phone /PAD need to support 2*2MIMO technology. In fact, due to signal loss, attenuation, channel congestion and interference, the actual bandwidth is about 50-70% of the theoretical value.
In short, when purchasing a router, it is recommended that the financial owner buy a full Gigabit wireless router (the wired port is also a Gigabit port), which supports the 802. 1 1ac protocol and supports 2*2MIMO or higher 4*4MIMO.
Wi-FiAP panel information socket
In order to facilitate the arrangement and storage of information lines, optical cats, routers and redundant network lines are generally placed in weak boxes. However, there will be a problem here: weak boxes are generally installed under the entrance. If the entrance is too far away from the bedroom and bathroom, it is likely that there is no network information in the bathroom and bedroom or the network signal is very poor.
Here is an artifact to save network signals, which is to install Wi-FiAP panels in the living room, bedroom, study and other areas during decoration.
The Wi-FiAP panel is equivalent to a router installed on the wall. Just press the middle button to realize seamless Wi-Fi roaming, and easily solve the Wi-Fi dead angle where the wireless router has limited signal coverage and the signal is easily attenuated by the wall.
Weak box
Weak box is an indispensable part of "home appliances". Why do you say that? "Household appliances" refers to the transmission, distribution and safe use of electric energy in the home environment. In a word, it is the comprehensive layout and management of strong and weak electricity in the home, including 220V voltage circuit breakers, switch sockets, plug-ins, and weak electricity management equipment for audio signals. Weak electricity box is a weak electricity management device for unified management of sound signals in household appliances.
As can be seen from the above, the weak electrical box is a necessary item in home decoration, not only because it is a centralized box for communication information management, responsible for receiving network cables and weak electrical equipment, making the whole home beautiful;
So how do we choose the weak box? In most cases, weak electrical boxes are embedded in the wall, and the requirements for the shell are higher: compression resistance, rust resistance and high temperature resistance, otherwise it will be easy to deform and rust after a long time. And now families pay more and more attention to the beauty of products, so the design of weak box can also be used as a reference factor when purchasing.
For example, Siemens Yi Rui series weak boxes have performed very well in these four points.
Siemens Yi Rui series 6-bit weak box
? In terms of compression resistance, both the 6-position box and the 10-position box are made of cold-rolled steel plates with the thickness of 1.2mm, which can fully ensure the mechanical strength of the box without worrying about the potential risks caused by shell deformation;
? In terms of rust prevention, the metal parts of all products in this series can meet the 96-hour salt spray test, reach the highest rust prevention standard in the industry, and prolong the service life.
? In terms of high temperature resistance, the plastic cover plate of Yi Rui series weak electrical box can meet the requirements of 850-degree glow wire test, far exceeding competitors;
? In addition, the gold-plated layer thickness of Yi Rui series weak box network module wire is >: 1.26um, and the gold-plated layer thickness of telephone module conductor is >: 0.76um, which ensures that the signal is still stable and reliable after long-term use.

Finally, product design, Siemens patent design, easy and flexible placement of ONU light cats. It is the most space-saving box on the market at present, which can hold all kinds of light cats with the smallest wall opening. Moreover, Yi Rui series weak boxes have rear wiring design, and the interface is simple and beautiful; At the same time, there are no exposed screws on the installation surface, which is integrated with the wall surface, and the whole is simple and atmospheric.
Post-wiring design
PS。 Siemens Yi Rui series weak boxes all meet RoHS standards, and every family can buy them with confidence.
In addition, the network cable embedded in the wall is connected to the weak current household box and the network information socket. Some decorators use inferior network cables in order to save costs. This poor quality network cable, because of poor transmission performance, will consume part of the network speed, and the consumption of network speed will be even greater after a long time! This is also a reason why the network speed is not good.
In a word, the location of the router is worthy of attention, and whether you can eat chicken smoothly depends largely on it. Moreover, the selection of weak electric box is also a very important part of household appliances, which not only affects the home network speed, but also helps to orderly concentrate all kinds of weak electric lines. Readers should understand why their home network speed is not strong when they see this, right? Of course, as far as the network speed itself is concerned, in addition to the above, broadband bandwidth, weather changes, networking equipment configuration and other factors will have an impact on it. I hope this article can help readers!
