That's some great news, my parents live in Fox River Grove and when I was home from school over the summer I noticed there was a dead spot in CL along route 31 and in Cary. I'm guessing the sites at Cog Circle by Portillo's and the water tower in downtown Cary are still not live with LTE? When I'm out there I mostly see my phone connecting to those sites when I'm in Cary or Crystal lake. When I'm at home in Fox River Grove it's usually a split between Cold Spring Rd, the downtown Cary water tower and the Kelsey Rd site, and LTE being pretty scarce.
I know that there is a Clear site located on the Ski Jump in FRG, and that there is a USSC site on top of the FRG water tower. I hope they convert those to NV eventually, because Sprint doesn't have the best coverage in FRG.
And those sites that still aren't live with LTE, don't they have microwave back haul installed?
