2 DIPLOMA IN WAN AND WIRELESS ENGINEERING WELCOME TO THE DWE TRAINING PROGRAM OBJECTIVE AND SCOPE OF THE COURSE We, proudly introduce our DWE (Diploma in WAN and Wireless Engineering) course package, for people aspiring to have careers as WAN administrators or wireless administrators, who want an objective assessment of their skills as well as certification of their accomplishments. Network engineers sometimes known as network administrators, design, install and maintain computer communication systems within an organisation or between organisations. These systems allow workers to share files and resources, access the internet and , and collect and process data. A network, that is no longer used just for transactions, but for realtime collaboration to deliver the experience anytime and anywhere. Local Area Networks (LANs) - connecting workstations within an office, building or a limited area. Metropolitan Area Networks (MANs) - linking networks citywide or across a region. Wide Area Networks (WANs) - linking national or international networks. Global Area Networks (GANs) - combining networks over an unlimited geographical area. Network engineers' key responsibilities are to make sure that an organisation's computer system has the capacity to meet its business needs and is secure. Example: installing a new computer-based call handling system for a contact centre or servicing a bank's ATM Network. Typical duties include: Installing new software and hardware Setting up user-accounts, permissions and passwords Maintaining adequate security, especially where networks link to the internet Finding and fixing faults Implementing preventative maintenance schedules Giving technical support for end-users Providing training on new systems 2

3 Carrying out day-to-day administration and monitoring network use Planning and implementing future developments. Opportunities come capitalize on the growth! Whether you're thinking of getting into networking or have already been a part of it, you'll find a bright growth path ahead of you. Starting with network or system administration, career opportunities can open up in a lot of areas ranging from security, storage, WAN management, wireless, data centre management, Unified Communications, and many others. Career Path In an enterprise, a professional will typically start his career as a LAN administrator. Later with some experience he can take responsibilities of a senior level network manager who will be into planning and designing of LAN, including wireless and security. After acquiring some years of experience in planning and designing the network, a professional can take the role of a consultant as he would have experience in implementing the network setup and also have knowledge of technologies and hardware requirements. But to grow, he'll have to enhance his skill set beyond the knowledge of LAN configuration and administration, and look ahead to technologies that are part of networking. A few of the specialized streams of networking domains, where network professionals are in demand, include Storage, Security, WAN, Virtualization / Consolidation, Wireless and Mobility. The networking domain has a plethora of job titles, many of which refer to very similar and at times identical job roles, like Network Engineer, Network Administrator, Network Analyst, Systems Administrator, etc. Now with specializations coming into picture, new job titles that are coming up in the enterprises include Security Analyst for network security, Network Storage Administrator for storage management and Wireless Network Engineer for a Wi-Fi consulting agency. The audience for this course package ranges from people with knowledge in system administration to individuals who are working in intermediate positions in the field and also who want an objective assessment of their skills and would like certification of their accomplishments as well. 3

Before you install or even select new hardware, you must think about issues such as hardware compatibility, buses requirements, and ergonomics. Planning a network is a combination of common sense and knowledge about the hardware & software that make up the network. Therefore, this session examines some of the factors you should consider during the network planning static and discusses how your discussion can affect your future actions.

10 WIDE AREA NETWORK Wide Area Network (WANs) and their component technologies continue to increase in importance. Not very many years ago about the only need most companies had poor WANs was to internetwork two or more work locations. for example, a company with only a single work location might need a robust connection to the internet to support marketing, customer care and many other functions. CISCO makes a smorgasbord of routers, hub and switches product, that s why this model follows that by understanding all that available form CISCO, you can make much more informed decision about exactly which products will most strategically meet your networking needs.

13 WIRELESS NETWORK Wireless LAN is closely grouped system of device that communicates via radio waves instead of wires. Wireless LANs typically assignment of replace wired computer networks, providing users with more flexibility and freedom of movement with in the workspace. User can occur per company internet or even the World Wide Web from any where on the company campus without relying on the availability of wired cables and connection. If information is the lifeblood of today s business environment, then wireless network are its heart. Wide verities of industries have discovered the benefit WLAN can bring not only to daily task but also to the balance sheets. That is why this module covers the detailed about Wireless networking which help the students to gain international certifications like CWNA (certified wireless network administrator).the international certification will get you started in your wireless career by ensuring you have the skills to successfully administer enterprise-class wireless LANs.
