The ATT building where we have collocation already however, would be 
quick and easy to add microwave, but they formally resist that idea and 
are of the position that we don't have the right to do so, despite it 
being in our interconnection agreement. They are digging in their heels 
and will have be addressed by the regulatory authority, which is not a 
quick process.  The cost of pulling a new cable to another building that 
has sufficient line of sight, is prohibitive. Not impossible, but could 
add six figures to the cost, and therefore is not realistic.
