Very High Throughput 60GHz wireless enterprise networks over GPON infrastructure

Abstract

We present our findings regarding the deployment of 60GHz Gigabit WLAN RoF enterprise networks operating under Medium Transparent-MAC protocols over existing GPON infrastructures. Two possible network scenarios are investigated: i) the GPON-plus-RoF approach considering the 60GHz RoF bus WLAN connected to a conventional GPON ONU, and ii)the RoF-over-PON, which fuses the GPON OLT with the MT-MAC Access Gate at the same Central Office (CO). Simulation-based throughput and delay results are obtained for both network scenarios, revealing the dependence of the 60GHz enterprise network performance on several network planning parameters such as the number of optical wavelengths being available to the enterprise network, the GPON dedicated bandwidth, the load of the enterprise network as well as the percentage of inter- and intra-LAN traffic, highlighting in each case the prevailing architecture.
