This article explores the advantages and applications of dual-band Wi-Fi and Multi-Link Operation (MLO) in smart homes. Dual-band Wi-Fi utilizes both the 2.4 GHz and 5 GHz frequency bands, offering flexible connectivity options for smart devices. The 2.4 GHz band features strong penetration and coverage, making it suitable for devices requiring stable connections, while the 5 GHz band delivers faster speeds ideal for high-bandwidth applications. MLO enables devices to connect to both bands simultaneously, enhancing connection reliability and speed to optimize the smart home networking experience. Selecting an appropriate dual-band router and managing device connections effectively can boost network performance to meet the growing demands of smart devices. By embracing these advanced technologies, users can ensure their home networks remain efficient and stable for years to come.
