SignalStrength Parameter Validation

No value for 'band' for 2G and 3G
In GSM and WCDMA networks, the concept of "bands"as it exists in LTE and NR is not directly applicable. GSM and WCDMA networks operate on specific frequency bands allocated by regulatory bodies, but these bands are typically not exposed directly in the same way as in LTEand NR.
Instead,we have RFCN (Radio Frequency Channel Number)

Not accessible: 5G- gNodeB
