Executive Summary
The main purpose of this report is to discuss the concept of this technology including its characteristics, structure, types and some typical application. The report will start with an overall introduction to wide area network, and then identify the key characteristics of this technology. Generally, the data transmission rate of wide area network is lower than local area network (LAN), but with the development of technology, this data transmission rate is improved dramatically, it could achieve 2.4 Gbps or even higher currently. Thus, it could meet a great number of requirements. After that, it will analyze the key technologies used in wide area network and the main services it provides. The report will end with some recommendations to improve and make good use of this technology.

Introduction
Wide Area Network (WAN) could connect across a large physical area. Normally, it can connect a plurality of city or country, or across several continents and can provide remote communication. Wide area network is a kind of cross region data communication network using the equipment provided by telecommunications operators as the information transmission platform. Refering to the OSI reference model, WAN technologies are mainly located in the bottom three levels. respectively is the physical layer, data link layer and network layer (Groth & Skandler, 2009). There are three typical types of wide area network. The first one is Public transport network which is normally set up, managed and controlled by Governments ' Telecommunications Department. The transmission and exchanging devices could be provided to any organizations. It includes circuit switched
