Converged optical wireless network featuring active and dynamic routing of radio signals

This paper presents a converged fibre-to-the-home (FTTH) based access network architecture and wireless services. In order to fulfill the bandwidth demands form end users, dynamic architecture is proposed featuring co-existence of LTE, WiMax and UWB technologies. Hybrid wavelength division multiplexing (WDM) and time division multiplexing (TDM) based optical access network inherits reconfigurable provision which enhance the ability to allocate different wavelengths to different optical networking units (ONUs) on demand. Radio signals are delivered to the ONUs by utilizing the state of art properties of arrayed waveguide grating (AWG) and array of semiconductor operational amplifiers (SOAs) at the central office. In order to have better comparison of radio signals, all the signals is simulated with 16QAM based OFDM technology. Error vector magnitudes (EVMs) are investigated and it is noted that the maximum transmission distances of WiMax, LTE and UWB, without dispersion compensation, are approximately 60km, 75km and 75km respectively.
