Claim 19:
20. A central radio access network (RAN) node for a small cell of a wireless access network, comprising:
a processor; and
a memory configured to store a plurality of computer-executable instructions therein, which, when executed by the processor, cause the central RAN node to:
transmit a communication signal to a plurality of remote analog radio units operably coupled with the central RAN node along a single distribution line;
enable at least one remote radio unit of the plurality of remote analog radio units to send the communication signal to at least one user equipment device (UE) operating within a communication range of the at least one remote radio unit;
send a switching tone to the at least one remote radio unit separate from the communication signal; and
cause the at least one remote radio unit to, upon detection of the switching tone, transmit a UE signal from the at least one UE to the central RAN node.
