Planning your home IT infrastructure



infroTo whom is this post addressed -  Beginner
As far back as 20 years ago, whole infrastructure of the home was the computer by itself. All what you have had to do was connect it to the power outlet and phone line. Nowadays the situation has changed. We have fiber optic Internet connection, wireless access points, home networks, smart TV sets, PlayStations, smart refrigerators, cell phones, and thermostats. All this stuff interacts by itself and with the Internet.
There are a couple of circumstances that determine the way you go: The simplest situation is when you buy a brand-new house or building and you can build all the infrastructure from scratch.  Another situation is a buying/renting of a home or apartments. From this perspective you need to choose what to do: change existing wiring systems that will be tied with high expenses or deployment of new wireless.
The pluses of wireless system are low price, big coverage, high speed, and relative simplicity of installation. The minuses are lower stability and speed compared with wired connections.
So what to do? The first thing you need is to calculate your devices (how many have wireless option and how many can be plugged by cord), determine the goals you are trying to reach with this equipment, the space you would like to cover, and money you are ready to spend. After this you need to make an investigation of the existing system. How many Ethernet network outlets (RJ45) you have in each room, how are they all connected together, where are Internet providers’ devices placed.
Next step is choosing network devices. If you go to a wired system you need to buy a switch which allows you connect all devices to it. The modern Internet routers have included four to six network sockets that pretty well cover a small apartment or one room. If it is not enough – you need to buy a switch based on the quantity of your devices. If you go wireless – you need to check how many devices can be connected to the access point. Moreover you have to check the maximum speed that you can give your wireless router. For modern systems which require a photo and video files transfer, you need at least a type N router (N is the protocol of communication between router and device). If you buy a new router – look to the newest AC type that will give you better performance as well as will be compatible with all your gadgets at least the next couple years. You can read more about common network issues in the article 10 biggest home networking mistakes.
After plugin of all devices you will have a switch or access point connected to the Internet from one side and all your devices from another. There are many tricky questions about setting up this all together, but this will be the topic of our next post. At the end of this post I would like to renew the basiсs you have to keep in mind while building the home network:
money you are ready to spend
existing network
connection speed
device quantity
