WiFi 7 Wireless-First Migration¶
A practitioner's guide to designing, deploying, and operating an enterprise WiFi 7 (802.11be) network — migrating from a wired-default to a wireless-first workspace across a global multi-site estate.
About This Documentation¶
This guide provides end-to-end coverage of an enterprise WiFi 7 deployment, from technology fundamentals and infrastructure assessment through pilot architecture, phased rollout, day-of deployment procedures, and ongoing operations. It is organized into sixteen chapters plus reference appendices.
Target audience: Network architects, wireless engineers, security teams, and operations staff planning or executing a WiFi 7 migration.
Deployment scenario: A wireless-first transformation across 19 global sites (APAC, EMEA, Americas) supporting roughly 15,000 users, built on Cisco Catalyst WiFi 7 access points, Catalyst 9800 controllers, SD-Access fabric, and ISE-based Zero Trust segmentation.
Technology stack: Cisco Catalyst 9178I-BE access points (802.11be), Catalyst 9800-40 WLC, Catalyst Center (DNAC), ISE 3.3 with TrustSec and pxGrid, 6 GHz spectrum with 320 MHz channels and Multi-Link Operation (MLO).

AI-Assisted Documentation Disclosure¶
This documentation was produced with AI assistance (Claude, by Anthropic) working under practitioner direction. Architecture decisions, technical accuracy, and editorial judgment are the practitioner's contribution; the AI provided drafting speed and structural consistency. The deployment scenario uses AbhavTech as an illustrative organization, while the design patterns and procedures reflect real-world enterprise WiFi 7 practice.
