Hi guys,
Today I was called at a local school to see if I can help them get the second floor connected to their LAN, but they have one problem: Due to some internal regulations, no more penetration of the walls, so no wires, I have to do this with WiFi.
They actually need only one room (class) to get WiFi\Lan and that room is almost on top of of the room where they have the rack. I did a basic test using my smartphone and some apps and it seems that there is low-to-none interference in the building, no other wifi networks, so clean channels, I spoke with the administrator and as far as he knows the walls are old and not coated with metallic mesh.
Turning on wireless hotspot on one of my smartphones and leave it in the class with the rack on 1st floor I was able to see the network with a second smartphone, though the signal strenght was low, but I guess I can succeed and connect the two floors together, I just don't know wich way would be the best and cost-effective.
I thought about using two rb951 2hnd, or two hAp lites, but what about Mikrotik's ntream?
