1. An apparatus comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions and cause the apparatus to perform,
receiving, in a first signal pathway, at least a first signal at a receiving frequency and associated with a first radio wave characteristic;
receiving, in a second signal pathway, at least a second signal at the receiving frequency and associated with a second, different radio wave characteristic;
changing the frequency of at least one of the first signal and the second signal to provide an intermediate first signal and an intermediate second signal such that the intermediate first signal and the intermediate second signal have different frequencies;
multiplexing the intermediate first signal and the intermediate second signal to allow the intermediate first signal and the intermediate second signal to be transmitted together via a single wired connection;
receiving a multiplexed signal via the single wired connection, the multiplexed signal comprising an intermediate third signal and an intermediate fourth signal having different frequencies, the intermediate third signal associated with a third radio wave characteristic and the intermediate fourth signal associated with a fourth radio wave characteristic, different to the third radio wave characteristic; and
separating the intermediate third signal and the intermediate fourth signal into separate signals;
changing the frequency of at least one of the intermediate third signal and the intermediate fourth signal to provide a third signal and a fourth signal at a transmission frequency;
transmitting, in the first signal pathway, the third signal; and
transmitting, in the second signal pathway, the fourth signal,
the receiving frequency being in a range from 21 GHz to 71 GHz, and
the apparatus, to perform the changing the frequency of at least one of the first signal and the second signal, is caused to perform,
downconverting the first signal to a first intermediate frequency lower than the receiving frequency; and
downconverting the second signal to a second intermediate frequency lower than the receiving frequency and different to the first intermediate frequency.
