Still generic story.
Remember that math: enB ID * 256 + Sector ID = Current Cell ID
eNB ID - ID of your Tower for your ISP (other ISP at the same tower and antennas have other eNB ID)
Sector ID - is a ID of sector antenna for specific band, like eg. id 0,1,2,3 can be 4 sides of the world for Band20 and 4,5,6 at 3 sides of the world and any other combination…
Thanks to Watch LTE parameters: http://forum.mikrotik.com/t/r11e-lte6-2ca-not-staying-connected/136004/22 you can track changes at connection.
Remember that SXTR is good for 3-4km, LHGR to 8-12km max
People general use CellMapper website for searching Towers.. but it’s not proof for data on it.
Provice both eatfcn what you receive at B3 and B20 from any tower/antenna.
