A radio access network (RAN) node is provided for a small cell of a wireless access network having a coaxial line. The RAN node includes an input operably coupled with the coaxial line and an output configured to wirelessly communicate with at least one user equipment device within an operable vicinity of the wireless access network. The RAN node further includes a transmission path configured to (i) connect the input to the output, and (ii) communicate a first radio frequency (RF) signal from the input to the output, and a reception path separate from the transmission path, and configured to (i) connect the output to the input, and (ii) communicate a second radio frequency (RF) signal from the output to the input. The RAN node is configured to dynamically switch between the transmission path and the reception path in response to a tone received from the wireless access network.
