There will be 81 sites. Each with 5 channels. The current license list isn't even close to being fully populated.
Frequencies are identified, some licensed by WISCOM, some still licensed and available from the original licensees prior to transfer. Paperwork is, indeed, a big issue for this project and I'd assume we won't see it all done for a while. Testing can even be on the vendor's own test channels. Current testing is minimal and variable and subject to change, as the engineer advises. Don't look for any activitiy for a while, bottom line.
To answer another question: The state project web site shows a lot of information, including Grant Co having two sites: Bloomington and Happy Corners. Surrounding area sites include Highland, Darlington, and Seneca. They are shooting for 95% mobile coverage, statewide, so sites are not county-specific, rather terrain-specific. As a result, some counties will have one, two or even NO sites.
