802.11 Wireless LAN Fundamentals (Fundamentals)by Pejman Roshan
Synopses & Reviews
Master the basics in designing, building, and managing a Cisco Aironet WLAN.
802.11 Wireless LAN Fundamentals gives networking engineers and IT professionals the knowledge they need to design, deploy, manage, and troubleshoot their own wireless local-area networks (WLANs). Starting with an overview of the technology and architecture of WLANs, the book goes on to explain services and advanced features that such applications can provide. Most importantly, it provides practical design guidance and deployment recommendations.
Wireless LANs connect computer networks via radio transmissions instead of traditional phone lines or cables. Benefits to these systems 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 phone lines are no longer necessary, saving the cost of line rental and equipment upkeep. Finally, flexibility in campus network design increases significantly for the networking professional, while the network accessibility and usefulness increases for the individual users.
802.11 Wireless LAN Fundamentals helps networking professionals realize these benefits by helping them understand how to design, build, and maintain these networks, as well as how to justify their value within organizations.
