Need a wireless router recommendation to server 40+ people

[Alex Volkov]

I'm wondering if it is possible to replace multi-access point setup with a
single PC running linux with 3 or more wireless PCI cards and a couple of
long range external antennas. Or packing that many antennas within about 2-1
meter radius will result in too much interference?
