In a mobile phone, which of the following wireless technologies is MOST likely to provide Internet connectivity?
In a mobile phone, Internet connectivity is most likely provided through RF (Radio Frequency) technologies. RF refers to the use of electromagnetic waves in the radio frequency range for various wireless communications, including cellular networks (such as 3G, 4G, and 5G), Wi-Fi, and Bluetooth. These technologies enable mobile devices to connect to the Internet and access online services.
