I don't agree about them being "hosed" by tower companies. I have a tower that still has one of their "cell sites" on it.
They installed a full three faced array mount, stuck 5 feet off the tower on all sides, identical to what the cellular guys used. Then they mounted 4, 30 degree dual band 2.4/900 sectors on each face along with 12 of their pole-top type radios. All this into several heavy NEMA enclosures followed by heavy, custom Ethernet and Power cables running in metal conduit down to the building. Inside was a 7 foot cabinet full of equipment (requiring a second meter) plus additional wall enclosures housing lightning protectors, telco DEMARCs and who knows what else. The antenna array wiggled back and forth causing great turning moment on the tower and is STILL THERE to this day because they didn't even clean up after themselves. Don't forget the thousands of pole top nodes they abandoned that use power and space on the streetlights to this very day. This was done all over the metro area on 4.5 mile centers! For the weight, load, and space taken up, they should have been paying broadband cellular rates on all of these.

They were great engineers. The technology just worked at 128mbps. They failed because they didn;t know how to do math. They were over confident as VC funded companies were back then, and Tower companies hosed them on reoccurring costs, and them approving way to much for their build out costs.
