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.
