This paper presents the discrete-event simulator of the low-voltage broadband power line communication (BPLC) access network in accordance with the IEEE P1901 standard. The proposed simulator enables the cross-layer simulation of the physical (PHY) and medium access control (MAC) layer. The performance of the digital communication techniques at the physical layer and the characteristics of the shared medium are integrated at the MAC layer through the probability of the bit error. The proposed simulator was applied in order to estimate the throughput in the simple BPLC network. For the selected set of parameters at the MAC and PHY layer in the test network, the simulator recorded average download throughput of 900kbps, registration time of 36ms and packet delivery ratio of for 0.98 between each station and the HE.

Abstract Integration of mobile backhaul and broadband fixed access networks is a practical and inexpensive solution. This study discusses integration in urban metropolitan areas when a broadband fixed access network is based on gigabit-capable passive optical network and mobile backhaul is intended for the 3G global system for mobile communication networks. Bandwidth and quality of recovery clock are considered as two main parameters for successful integration. Two clock recovery approaches are described, and their performances are measured on the real gigabit-capable passive optical network system.

For supporters of fiber-optic technologies

In this paper we analyze the requirements for the complex information system used to support a modern global university. We outline the architecture for this system based on the emerging cloud computing platforms and present an example of managing a university course by incorporating different Google cloud services within the Google Sites.

Usage of Gigabit-capable passive optical network (GPON) as mobile backhaul is described. Two clock recovery approaches for GPON-based mobile backhaul architecture for 2G / 3G GSM (Global System for Mobile communication) network are described and their performances are compared. Measurement of quality of recovered clock on real GPON is performed and discussed.
