The capability that manages a mobile device’s connection to available wireless networks by intelligently selecting the optimal one based on signal strength, data speeds, and network stability is a core function of modern operating systems. For instance, a device might automatically transition from a weaker Wi-Fi signal to a stronger cellular data connection, or between different Wi-Fi networks, aiming for uninterrupted connectivity.
This functionality aims to enhance user experience by reducing connection drops and ensuring reliable internet access. Historically, mobile devices required manual selection of preferred networks. This feature automates that process, freeing the user from constantly monitoring and adjusting network connections, leading to better power management and reduced data consumption costs.
