The capacity of an Android device to select a specific radio frequency for Wi-Fi connectivity refers to its ability to prioritize or connect exclusively to a 2.4 GHz network. This selection process is often encountered when a user desires to ensure compatibility with older devices or when experiencing connectivity issues on a 5 GHz network. For example, if a smart home device only supports the 2.4 GHz band, forcing an Android device to connect to this frequency can be necessary for successful integration.
Employing this frequency offers the benefit of greater range and better penetration through walls and obstacles compared to higher frequency bands. Historically, the 2.4 GHz band was the predominant frequency for Wi-Fi, making it more universally compatible. However, it can also be more susceptible to interference from other devices operating on the same frequency, such as Bluetooth devices and microwaves.
