988  Zigbee: Comprehensive Review

988.1 Introduction

This comprehensive review consolidates Zigbee knowledge across network deployment, protocol selection, and practical implementation. Use this index to navigate to focused chapters covering specific aspects of Zigbee mastery.

This chapter is a capstone for the Zigbee material. Work through it after:

  • zigbee-fundamentals-and-architecture.qmd - device types, clusters, and network formation.
  • zigbee-hands-on-and-future.qmd - concrete use cases and implementations.

If youโ€™re unsure about basic terms like PAN ID, coordinator/router/end device, or AODV routing, pause and revisit the fundamentals before continuing.

988.2 Review Chapters

This comprehensive review is organized into three focused chapters:

988.2.1 1. Network Deployment and Planning

Zigbee Review: Network Deployment

  • Network deployment planner with router placement optimization
  • Mesh self-healing visualizer showing AODV route recovery
  • 2.4 GHz channel analyzer for Wi-Fi coexistence
  • Practice questions on multi-floor building design
  • Battery life calculations and coverage requirements

Topics: Router placement (10-15m spacing), redundancy (2-3x minimum), sleep current optimization, channel selection (25/26 recommended), MAC ACK timeouts, RERR/RREQ/RREP messaging.

988.2.2 2. Protocol Selection and Comparison

Zigbee Review: Protocol Selection

  • Protocol comparison matrix (Zigbee vs Thread vs Matter)
  • Decision framework for time-to-market, device count, ecosystem, budget
  • Dual-protocol strategy: Zigbee now + Matter firmware later
  • Security features: Trust Center and Green Power

Topics: Zigbee 3.0 vs Thread 1.3 vs Matter 1.0, dual-protocol chips ($1.50 premium), Green Power energy harvesting, Trust Center key management.

988.2.3 3. Worked Examples

Zigbee Review: Worked Examples

  • Mesh coverage calculation for warehouse (5,000 sqm)
  • Route recovery timing after router failure (~550ms)
  • Channel selection for Wi-Fi congested environments
  • Multi-endpoint device design (4-outlet power strip)
  • Binding troubleshooting (address cache staleness)

Topics: Coverage area formulas, AODV timing analysis, frequency mapping, endpoint architecture, group vs IEEE bindings.

988.3 Learning Objectives

After completing all review chapters, you will be able to:
