Wi-Fi for a country house: how to properly equip a network

The need to organize a separateInternet connection in a country house and its sharing with all devices of a home Wi-Fi-network can arise for the solution of various tasks. For example, for a video surveillance system and the creation of a single information space Design studio "Your space" with IT expert Vitaly Krikov continues to cover the construction of a Wi-Fi network for a country house. The first part of the large material can be read. On the example of a real project of installing a video surveillance system, experts told how to stay online for hundreds of kilometers from a large city. Vitaly Krikov, "Its space" IT-expert design studio, which has existed for more than 15 years. In it you can order a design of a country house or an apartment with a projected local network. Selection and adjustment of equipment can also be carried out by the company's specialists. The customer wanted to access the video from the cameras, especially the actual issue of remote viewing. During the discussion it was decided to expand the project to the organization of a local network for the integration of all home devices into a single information space. This solution allowed the customer to save on mobile traffic in the home Wi-Fi network and allowed centralized storage and use of data. It was necessary to unite:

  • Stationary computer with a large monitor;
  • Peripherals - printer and scanner. Previously, they were used only from a desktop computer, now it was envisaged to share it from any device connected to the local network;
  • Storage. It became a single center for storing the family digital archive and all the necessary documents with the possibility of exchange between users;
  • Modern TV and game console. They became networked, as was supposed by their producers;
  • A video surveillance system with the possibility of remote access.
  • For maximum performanceHome network it was decided to build it on wired segments, and for Wi-Fi - to use seamless roaming technology. In this way, a truly modern local network was designed that could last for quite a long time without needing to be modernized. Repair, which took place at this time in the house, allowed without any unnecessary problems to lay all the necessary connections. Vitaly Krikov, "Your space": -If you are repairing your apartment or country house, make a local network project - this will help you avoid problems in the future. Why was it so important to use a seamlessWi-Fi roaming? The meaning of this technology is that devices connected to a wireless network will not lose connection when moving around the house: the controller evaluates the signal level and, if necessary, switches the devices to a more suitable access point. The house is brick, the floors between the floors are reinforced, so finding a place in which the Wi-Fi-router will provide a high-speed network to all rooms is impossible. Installing multiple Wi-Fi repeaters would solve the problem with the coating, but the loss in speed would be very large. Even one Wi-Fi-repeater can reduce the overall network speed, and in our project they needed to use several. Using PowerLine adapters could unify only wired devices, but not Wi-Fi. The most effective ways of amplifying the signal can be read. Vitaly Krikov, "Your space": - All users of the local network should have access to the Internet. In our case, for the organization of the Internet connection, it was decided to use the mobile network as the only solution available today. In this case, the possibility of reorienting to any other connection was envisaged. To create an Internet connection through a cellular network, you need:

  • SIM card of the selected operator;
  • USB-modem;
  • External antenna;
  • Assembly kit for integration into a common system.
  • For what a SIM card and a modem are needed -Explanation requires the use of an external antenna. Its main purpose is to amplify the signal. And without it, there are places in the house where you can get a sufficient signal, but when using an external antenna permanently installed in the open space, the reception will always be better. Also, the antenna acts as a "shor" for the modem, preventing its switching between base stations, which is accompanied by a disconnection of the connection. Stationary installation dictates certain conditionsUse. The planned home network requires the organization of a "communication center" - a place in which all wired segments will be consolidated and where a device will be installed that will unite everything into a common structure. The communication center does not have to be in the same place as the kit that provides the Internet connection, but it is necessary to connect them. Vitaly Krikov, "Your space": - Now a huge number of ready-made kits for Internet connection are offered. Why did not we use them? They did not suit us. Absolutely. Such kits do not provide for the level of integration into the local network that we need. The way to connect the antenna, the level of Wi-Fi signal and the need to use Wi-Fi-repeaters to expand the reception area - all this was not suitable for us, and the price of such a kit did not allow to tolerate these shortcomings. The location of the planned installation should be inCoverage area network 4G. You can check this on the official websites of mobile operators. The tariff for the right operator should be chosen very carefully, paying attention to traffic volume and speed. Value has everything, even at what time of the day the "unlimited" tariff operates. Vitaly Krikov, "Your space": - You can also ask around the neighbors. If you hear complaints about the impossibility of calling or about the fact that calls are often interrupted, most likely, the base station of this operator is heavily loaded and you can not get a normal connection. Unfortunately, only in practice it is possible to check the change in the speed of the Internet connection depending on the time of day and day of the week. But with the help of a special program for a smartphone you can measure the signal strength of the base station, determine in which direction it is relative to the planned installation site and, most importantly, check the connection itself. The modem must work with the selected operatorCellular communication in the 4G standard and be sure to be able to connect to an external antenna. Must be present MiMo technology - this means that the modem must have two connectors. It is desirable that he has the opportunity to fix the operating mode. By specifying the "LTE only" mode, it is possible to prevent switching to other, less speedy communication standards. The antenna should also have MiMo technology - that is, the possibility of increasing the bandwidth of the channel. Connect such an antenna using two connectors, and they should approach the selected modem. Vitaliy Krikov, "Your space": - Our smartphone with a SIM-card was able to establish an Internet connection in the house, which made it possible to opt for a panel-type antenna. It is easy to install and configure and provides sufficient signal amplification. Self-assembly and installation of this kitShould not cause problems. To orient the antenna to the base station, it is best to use the program that is offered with the modem. To do this, you need to connect the modem to a computer or other suitable device and, slowly moving the antenna in a horizontal plane, select the position at which the signal will be maximum. That's it: we've got an Internet connection that will be used in our network. Vitaly Krikov, "Your space": - A design was obtained, which connects to a router or a computer via USB-wire. It must be borne in mind that the length of such a wire is limited, it should not exceed 7 meters. The short wire that connects the antenna to the modem will reduce the signal loss during transmission, so we chose an antenna with a tight box for the modem. Obviously, in addition to the design of the antenna, the installation site also matters. If it is mounted on the mast, be sure to note that this antenna has the shape of a square: the resulting sail needs to be taken into account. After the Internet connection is established,You must make it available for all devices on your home network. This requires a router. In any electronics store there are a lot of them, but for the organization of seamless roaming Wi-Fi it is necessary to use semi-professional and professional equipment, the prices for which are higher, and the choice is much smaller. It is worth paying attention to the all-weather router with POE. With this technology, power is supplied via the same UTP wire to which it is connected to the local network. All-weather provides for operation on the street in our climate zone. This is important, since the place of its installation is the mast next to the antenna. This router solves the following tasks:

    • The WiFi-access point forms a wireless coverage area on the site near the house.
    • The use of POE technology virtually eliminates the restriction on the length of the connection. UTP-cable can be up to 100 meters - this is clearly enough.
    • The speed of the 1Gb wired interface is currently the highest for residential networks. It will provide comfortable work in the local network.
    • The ability to organize seamless Wi-Fi.

    It remains to design a communication center at home. By choosing a simple and reliable switch for connecting our wired segments, we integrate the entire network into a single space. Now any device connected to the network can use the Internet connection and access all internal resources. There is always the possibility of expanding the Wi-Fi zone inside the house. The choice of wired access points compatible with the router does not appear to be a problem. With this approach, the wireless connection speed will remain high in any part of the house. The number of points depends on the need. And it is always better to have a reserve, which you can use, by the way, not only for the local network. Phone, intercom, alarm - the need can arise the most different. This is an example of building a modern local network,Which makes it possible to combine wired and wireless technologies. It will suit both a country house and an office. You can use it as a template for your solution - of course, if you have some knowledge in this area. Vitaly Krikov, "Your space": - Naturally, it is interesting to know the budget. For the full implementation of this project with four access points, less than 50,000 rubles were allocated. Expensive or not? It depends on the importance of the tasks that the organization of the local network in the house allows the individual family to solve.
