thanks.
After many test I discover all stuff.
This is example at RouterBoard Chateau, RouterOS 7 beta 8
Quectel EG12 not support frequency lock to select band at any tower.
Quectel EG12 support one and many Cell Lock’s, you can enter max 20 of CellLock’s and it select the one with the best signal and set it as primary-band.
EARFCN give us center of frequency specific band of our ISP,
PHY-CELLID give us a specific antenna at tower
Example is base at signals like this one, Cell-Monitor show us:
interface/lte/cell-monitor lte1
Columns: PHY-CELLID, BAND, EARFCN, RSRP, RSRQ, RSSI, AGE
