Hard to say when it will be online. A little south of my location Verizon installed a new tower that had LTE antennas on it 2 years ago. It was not until late this summer they turned on the LTE. All depends on when they are ready to light up LTE in that area.
I agree with xrayman. Verizon co-located with Sprint on a monopole near me. (I was there with the engineers as they hauled the gear up) From start to finish the job took about 4 days. They turned it on about 2 weeks later. Has LTE antennas, but that has not been turned on yet. Still 3G for now. -- ... need help? »evdo-tips.com/
