با پیشرفت سریع تکنولولوژی و اقبال روز افزون تلفن های هوشمند، تبلت ها و … درخواست برای شبکه های بی سیم جهت ارائه سرویس های گوناگون از جمله اینترنت رو به افزایش است. این روزها وجود سرویس وای فای در یک رستوران، هتل، پارک و … از یک مزیت رقابتی به یک ضرورت بدل شده است. طراحی، راه اندازی و از همه مهم تر کارایی یک شبکه پوشش وای فای معلول موارد بسیاری است که در این مقاله تلاش شده است به صورت مختصر و گویا به آنها پرداخته شود. بدون شک عدم توجه به این موارد در هنگام طراحی می تواند کارایی شبکه راه اندازی شده را به صورت جدی تهدید کند. رعایت این موارد هنگام طراحی، بررسی و انجام تست های میدانی نظیر تست سیگنال و بهره گیری از تجربیات مختلف در محیط های مشابه می تواند کارایی یک شبکه وای فای را تا حد بسیار بالایی تضمین نماید.

A Practical Guide to Implementing 802.11n and 802.11ac Wireless Networks For Enterprise-Based Applications
Plan, deploy, and operate high-performance 802.11ac and 802.11n wireless networks
The new 802.11ac standard enables WLANs to deliver significantly higher performance. Network equipment manufacturers have refocused on 802.11ac- and 802.11n-compliant solutions, rapidly moving older versions of 802.11 toward “legacy” status. Now, there’s a complete guide to planning, designing, installing, testing, and supporting 802.11ac and 802.11n wireless networks in any environment, for virtually any application.
Jim Geier offers practical methods, tips, and recommendations that draw on his decades of experience deploying wireless solutions and shaping wireless standards. He carefully introduces 802.11ac’s fundamentally different design, site survey, implementation, and network configuration techniques, helping you maximize performance and avoid pitfalls.
Geier organizes each phase of WLAN deployment into clearly defined steps, making the entire planning and deployment process easy to understand and execute. He illuminates key concepts and methods through realistic case studies based on current Cisco products, while offering tips and techniques you can use with any vendor’s equipment. To build your skills with key tasks, you’ll find several hands-on exercises relying on free or inexpensive tools.
Whether you’re deploying an entirely new wireless network or migrating from older equipment, this guide contains all the expert knowledge you’ll need to succeed.
Jim Geier has 30 years of experience planning, designing, analyzing and implementing communications, wireless, and mobile systems. Geier is founder and Principal Consultant of Wireless-Nets, Ltd., providing wireless analysis and design services to product manufacturers. He is also president, CEO, and co-founder of Health Grade Networks, providing wireless network solutions to hospitals, airports, and manufacturing facilities. His books include the first edition of Designing and Deploying 802.11n Wireless Networks (Cisco Press); as well as Implementing 802.1X Security Solutions and Wireless Networking Handbook. Geier has been active in the IEEE 802.11 Working Group and Wi-Fi Alliance; has chaired the IEEE Computer Society (Dayton Section) and various conferences; and served as expert witness in patent litigation related to wireless and cellular technologies.
