Wireless convergence refers to the integration of different wireless technologies, such as Wi-Fi and cellular networks, to provide a seamless user experience. This is important because users expect to connect to the internet effortlessly, regardless of the network type. The challenge lies in achieving seamless roaming between these networks, as it requires coordination and agreements between various service providers and access networks.

Wi-Fi 7 introduces several enhancements over earlier standards like Wi-Fi 6 and 6E, including improved speed, reliability, and resilience. It features multi-link operation (MLO), allowing devices to connect over multiple channels simultaneously, which helps reduce latency and improve overall performance. This transformation is crucial as user demands for connectivity continue to grow, particularly in high-density environments.

Seamless roaming for Wi-Fi is more complex because, unlike cellular networks that have established roaming agreements among a limited number of providers, there are over 650 million Wi-Fi access networks globally. To address this, technologies like open roaming have been developed, allowing various access networks to authenticate users automatically, thereby simplifying the connectivity process and enhancing user experience.
