They recently updated the sensorly map in my area and I was amazed how accurate it is. I will post the link below shortly. http://www.sensorly.com/map/4G/US/USA/Sprint/lte_310sprint I want to understand more about the towers equipment. It seems that the drums that are installed are directional so they don't radiate in all direction. Here is a picture of one of the towers I describe. Edit; Ok so it seems that on this side of this tower is the 4g drum so when I get to the other side where the smaller drums are it drops to 3g. Which moron is incharge of upgrades is beyond me. Now to add to this they had 4g on a seperate tower going two different directions, but now that has changed and it is only in one direction off that tower. ?Did they use the parts off one to add to another.?. who knows. Yes the map actually reflects the change so I'm baffled as to the logic. I have some other pics I will post later.
