One problem with the "matrix of aerials" idea is that the coaxial cable that runs between them has to be low loss at GHz frequencies which is NOT cheap cable so running cat-5 out to 4 individual base stations is going to save money if the distances are long.
Running cable is running cable. As far as I am aware, the cost of running cable is only marginally affected by the actual cost of the cable.
My wireless broadband (recently upgraded from 2Mbps to 5Mbps too - woot!) was a bit of a surprise for the installers. Where my study is, they couldn't mount the antenna on the house in such a way to get line-of-sight to the base station (a few KM away)[1]. So they ended up having to mount the dish on the far corner of the house and run about 15m of coax about as round as your thumb (16mm outer diameter) to get the Cisco Aironet box in my study. It took them about 2 hours to finish the installation.
This little "extra" bit of wiring cost them a fortune (the cable is about $20/m apparently) and they only budget on about 3-5m of cable and 30-45 minutes. Good thing they do fixed price installations!! :P

[1] My house has that metalic "sarking" insulation in the roof which crucified the signal - they did try to beam it through the roof, but no joy; S/N ratio resulted in about ISDN speeds and huge amount of CRC errors and packet re-transmits.
Much the same effect as the colorbond fence between myself and my neighbours place - say "Faraday cage".
