Kernaali ToolsSelected band definitions, not an operator deployment map. Frequencies are MHz; paired ranges are uplink / downlink. Nominal labels are approximate. Check the exact modem’s supported bands and combinations.

Read the duplex mode
FDD: separate uplink/downlink spectrum.
TDD: shared spectrum, separated in time.
SDL: supplemental downlink; B32 cannot provide a standalone LTE connection.
Lower frequencies often help coverage. Higher frequencies may offer more capacity, but bandwidth, interference and load decide performance.
RouterOS field checks

LTE: band=3,7; NR: nr-band=78. Empty lists restore automatic band selection where supported. NSA needs LTE + 5G mode and a usable LTE anchor. A band filter is not a cell lock.
No listed band is guaranteed on every MikroTik device or Finnish/European network. Kernaali Tools is not affiliated with MikroTik.
