What type of reception would I get?

I have AT&T and I'm almost positive that my area is being upgraded to 4G. I currently get 2G (1-4 bars depending on what floor I'm on) at my house and want to know how good the service would be. I'm either 5.01 or 3.08 miles (straight line) from the at&t tower in my area and want to know aprx how fast the service would be on 4 bars of 4G with the iPhone 5s for both tower distances. Download and Upload please, I don't care about the latency. Also there would be an estimated 1500 users on the tower at a time.

Phone towers usually last around 3.5-4.5M.

Those are optimal conditions for good LTE bandwith and speed. I would closely estimate around 18-23 Mbps down- 8-10 Mbps Up.
