This chapter presents the application of extended wavelength band overlay over a splitter,
wireless-enabled PON to demonstrate enhanced scalability and dynamicity in comparison to the
architecture presented in the previous chapter. The overlapping cell concept is investigated that
in parallel with the wavelength band overlay is expected to provide increased wireless spectral
efficiency and resilience. The application of RoF is still in the focus by means of accessing each
remote ONU/BS sharing a given wavelength by FDM. To demonstrate the network scalability,
multiple FDM windows were routed over multiple wavelengths, with the slightest modification
in network hardware. EVM figures at selected remote base stations antenna inputs and BER
characteristics for users in the overlapping sectors have been recorded.
