Your question as you it asked got an honest answer except it wasn't specific enough. The Milwaukee market IS getting upgrades. But that's most southern Wisconsin (except southwestern WI - that's the Minneapolis market) including Dane, Jefferson, Waukesha, Milwaukee, Green, Rock, Walworth, Racine and Kenosha counties. Madison and some surrounding areas already have LTE. Fond Du Lac and surrounding areas are lit also. You should have asked if the CITY of Milwaukee is getting any work done. You might want to go back and ask again and toss in Waukesha, if you'd like.
Consider tossing in a few bucks to the site so you have access to the interactive maps & you can see what's already accepted for LTE in our market. You can also see which sites are getting NV in your areas of interest and you can keep an eye out for work being done.
