1. An apparatus for determining a suitability of a frequency band for data communication with a node by way of a communication channel, the apparatus comprising:
a receiver configured to receive first and second signals from the node by way of the communication channel, the first and second signals having frequencies within the frequency band; and
processing circuitry communicatively coupled to the receiver, the processing circuitry being configured to determine a calibration function depending on the first signal, process the second signal depending on the calibration function, determine the suitability of the frequency band for data communication with the node by way of the communication channel depending on the processed second signal, and output an indication of the suitability, wherein the processing circuitry is configured to determine the suitability of the frequency band for data communication with the node depending on the processed second signal by comparison of the processed second signal to predetermined reference data.
