This chapter evaluates the routing performance of the proposed network by means of WiMAX 
channel transmission over a PON infrastructure. To that extent, centralised WiMAX, utilising 
FDM to address multiple ONU/BSs, is displayed. Subsequently, network transmission 
performance figures are presented at the ONU/BS antennas and at radio receivers mainly in 
terms of EVMs and bit error rates (BERs) respectively.
5.1 Simulated RoF Access Network Architecture 
The focus of the work conducted in this chapter is to capture the merits of PONs and wireless 
interoperability in a new access network architecture [1] in terms of efficient bandwidth on-
demand provisioning and simple radio base stations. This is achieved by the application of 
centralised control in the OLT and time division multiplexing for upstream transmission 
enabling efficient dynamic bandwidth allocation for wireless users on a single wavelength as 
well as minimised optical beat interference at the optical receiver. Hence the network is able to
