Wireless LAN Fundamentals for Cisco

Course Specifications 4-days

Course Description:

Master the basics of designing, building and managing a Cisco Aironet WLAN.

Learn the basics of Wireless LANs with this concise design and deployment guide.
Understand implementation issues for a variety of environments including vertical, SOHO, and enterprise networks
Learn design and troubleshooting advice from real-world case studies.

Wireless LANs connect computer networks via radio transmissions instead of traditional phone lines or cables. Benefits to the network go well beyond getting rid of all the cables and wires. Campus networks can grow geographically larger while still retaining all their efficiency and speed. Additionally, cost savings can be realized when third-party lines are on longer necessary, saving the cost of equipment upkeep. Finally, flexibility in campus network design increases significantly for the networking professional, while accessibility and usefulness increases for the individual users.

Learn to design, develop and troubleshoot wireless local-area networks (WLANs). Starting with an overview of the technology and architecture the class will go on to explain services and advanced features that such applications can provide. Most importantly you will gain guidance and deployment recommendations.

Networking professionals will realize the benefits and learn to understand how to design and maintain these networks, as well as how to justify their value within their organization.
