Reliability analysis and loading application in circuits for next generation transport networks

Despite the rapid development of wireless communication and broadband applications for multimedia service, the 2 Mbps downlink data rate of the present 3G communication system cannot satisfy demand for a fast and high quality packet data service. The use of the HSDPA (High Speed Downlink Packet Access) air interface can upgrade the downlink packet data rate by 10.7~14.4 Mbps. This paper presents a mobile backhaul planning process and proposes a network reliability analysis of the ROADM design for next generation transport network. The term mobile backhaul refers to the fixed wire-line and/or wireless interconnections of mobile service base stations, and their connection to the core telecommunications network. We examine the NGSDH+OXC systems in the fixed wire-line for the HSDPA offload. The traffic statistics of the cell and the HSDPA area´s measurement results of its communication quality show that the planning is successful and satisfy the QoS standard.
