Lab Environments: Excellent for learning Cisco IOS wireless without WLC costs.
Small Offices: For a single AP or a small site, autonomous mode eliminates controller licensing fees.
Legacy Support: Many warehouses, schools, and retail stores still run these rugged, reliable APs.
EOL Status: Be aware that Cisco announced End-of-Life (EOL) for 3600/3700 series. No new security patches will be released. Using 15.2(2)JB is considered "as-is" for production networks.
