Recommend a solution for distributing Wi-Fi in a large building

Question

Computer networks

Hello!
I don't know much about stuff like this, so I thought I'd ask. Let's say there is a floor 20 meters long. There are about 10 offices on the floor. It is necessary to distribute the Internet via Wi-Fi. The only requirement is that it catches on the entire area. The walls are concrete, the thickness is significant - clearly more than half a meter.
What equipment do you recommend?

Answer 1

A reel of coaxial cable, several crabs, several antennas, bnc connectors, a puncher, one good router with an access point and a bnc connector, to which the entire network is screwed like a star. The router can be replaced by a server with a wafer card, almost any normal nettop is suitable as a server, if you don’t need a lot of power. Well, or if you need it - I prefer supermicro, but the choice of server hardware is rich even without my advice and preferences.
To breed such a miracle is not more difficult (technically) than a collective antenna for apartments in a residential building.
I myself have bred such networks and have been bred in Moscow and Zamkadye for several years, everyone is happy.
Tips about multiple routers are nonsense, just extra problems with setup and organization. And the main stupidity - you still have to take a puncher and pull cables, only in addition to twisted pair you will also need electricity.
And based on the theory of probability, the more things that can break, the sooner something will break. Coke and antennas break extremely difficult, and if there is a twisted pair cable cheaper than coke and routers are cheaper than antennas and a system administrator is cheaper than an installer ...

But I advise you to contact a specialist.

Answer 3

If ALL walls are more than half a meter: cables to cabinets, access points in cabinets.

Answer 4

The most budget option is to do WDS on inexpensive 802.11 n routers (for example, TP-Link). Start from the edge, then look for the most distant point where the signal is weaker than 15-20dB, put the next router in WDS mode in this place, and so on.
In an adult way, you need to do network planning with testing, organize a network at points with a controller, such as a tsiska or from the answer above. But this is completely different money.
