Optimized WiFi Network Deployment with OpenWRT and FreeRadius for Secure and Scalable Connectivity

Abstract

An innovative method for deploying a cost-effective and high-performance WiFi network is explored, focusing on OpenWRT-based routers and FreeRadius authentication. By standardizing hardware with TpLink WRT4300 devices and utilizing a custom OpenWRT firmware, seamless network management and easy device replacement are achieved. WPA2-Enterprise authentication, powered by a FreeRadius server on a Raspberry Pi 2, enhances security by providing unique credentials to users without requiring costly enterprise hardware. The proposed system ensures uninterrupted connectivity with multiple access points while enabling future integration with IoT and smart home automation. Designed for scalability and reliability, this approach delivers enterprise-grade security and performance while maintaining affordability for multi-user environments.
