Wi-Fi Network Diagnostics and Planning
The definitive guide for professionals who design, install, and maintain wireless networks.
Between the approved floor plan design and the user browsing at high speeds, there are technical decisions that distinguish a network that merely works from one that delivers on its promises. This book provides the knowledge necessary to make these decisions based on technical grounds - not guesswork.
The book is divided into three parts:
Part I - Fundamentals (Chapters 1 to 3) presents the physical concepts of electromagnetic wave propagation, the evolution of IEEE 802.11 standards (from Wi-Fi 4 to Wi-Fi 7), how CSMA/CA works, the 802.11 frame structure, and the association process between a client and an access point.
Part II - Planning and Design (Chapters 4 to 6) teaches propagation models (Friis, Log-Distance, One-Slope), coverage calculation with link budget, the interpretation of RSSI, SNR, and MCS, complete site survey methodology, and network planning for every environment typology - residences, retail stores, offices, hospitals, industries, distribution centers, and outdoor areas.
Part III - Diagnostics, Installation, and Maintenance (Chapters 7 to 12) covers essential diagnostic tools (Wireshark, iPerf3, native OS commands), troubleshooting flowcharts for common issues, interference analysis and channel selection, performance optimization through fine-tuning of power, roaming, and QoS, physical installation with PoE and structured cabling, validation tests, formal acceptance, professional documentation, continuous monitoring, periodic audits, and equipment replacement cycles.
Each chapter includes solved examples, quick-reference tables, practical checklists, and reflection questions - so that the knowledge is applied, not just read.
Exclusive bonus: all formulas and calculations from the book - link budget, free space path loss, path loss exponent, SNR to MCS, coverage radius, and much more - are available in an interactive system on the book's official website. The reader can input their own values and view the results in real time, transforming theory into immediate practice without the need for spreadsheets or manual calculators.
