Re: Got new amp still slow speeds

The pilot selection is strange. My CDU never sees other pilots even as a candidate unless there is a problem developing with my tower. Then I start to get multiple pilots conflicting with my connection effecting my performance. My tower is between me and Jim_in_Va yet I don't see his pilot (495). When my tower goes completely down I then can see it and connect to it although it's so far away that my performance is very iffy and at the same time a bunch of other pilots will override it and eventually knock me offline. So now when I see multiple pilots I know shortly my tower will be down. The last time it went down sprint advanced support checked and said there were multiple towers with a problem. Maybe the way they are linked has a lot to do with the pilots?

Jack, you've seen Jim's explanation of how towers are configured, I assume. The tower between you and Jim has at least three pilots to cover the entire 360 degree spectrum. When the pilot facing you goes 'down' you might then be picking up the 'backwash' of the one facing Jim (495), which would normally be overpowered by the one facing you if it were working properly. Also, since you are hitting the 495 antenna from the rear, it's likely you are getting a really fractured signal with lots of noise and the accompanying dataflow reductions

I wish I knew more about how these towers connect to the internet backbone. T1 lines are used, sometimes multiple T1 lines but how they interconnect, how they calculate how many T1 lines are needed for the radiated power, and how one tower/pilot affects another is a mystery to me. I never got into that particular aspect of electronics.

Do we have any experts here on this topic?
