The answer depends on what the connection is used for, and what version of Bluetooth you’re talking about. But if you’re looking for a quick answer, 2.4GHz will usually offer better performance than Bluetooth but use more power.
Bluetooth technology can be confusing because it actually uses the 2.4GHz band, but when people refer to 2.4GHz wireless connections, they’re not talking about Bluetooth. Bluetooth is a protocol, or language, used to transmit data over a short range using very little power. Bluetooth has some specific advantages over Wi-Fi signals that make it a great choice for some applications. It is much less susceptible to interference and uses less power in general than other 2.4GHz connections. These benefits come at a price for some applications though. When it comes to audio transmission, for example, Bluetooth has yet to duplicate the quality of a standard 2.4GHz connection.
Bluetooth technology has been refined over the years, but the older versions of it are still used for some applications. The different versions are numbered with the latest version being Bluetooth 5. The later versions have significantly increased the transmission range as well as the speed and capacity of earlier versions. In general, when shopping for Bluetooth devices, it’s best to look for devices using the latest version of Bluetooth.
