Abstract
Nowadays you can see everyone holding mobile phones on the street, used to be with only purely voice service till now, as the progress of the technology, function of wireless internet surfing is more and more valued. Whether video call, on-line browsing, or navigation is to provide consumer a multiple service. To fulfill most users’ request, high-speed downloading of 3G broadband system is needed. Telecom Operators start to create mass HSPA (High Speed Packet Access) system in 2009, meaning HSDPA (High Speed Downlink Packet Access) could reach 14.4Mbps and HSUPA (High Speed Uplink Packet Access) could reach 2Mbps. In order to fulfill this mass transportation, Telecom Operator not only has to upgrade the software and hardware of base stations (aka. Node B), the flow of physical circuit’s transmission also has to reach certain bandwidth. Considering investment cost and quality of service, fixed Telecom operators has take a new generation NG-SDH (Next Generation-Synchronous Digital Hierarchy). Using Ethernet to provide physical transmission of wireless internet browsing. This thesis is mainly discussing new generation Ethernet NG-SDH’s usage, while current base station using physical fiber circuit to provide transmission internet service quality. Through the result if the experiment, we will have a better reference for transmission service quality and solution when future operators planning transmission of HSPA+, 4G LTE (Long Term Evolution).
