Detailed explanation-1: -Bluetooth is the popular name for the 802.15 wireless networking standard, which is useful for creating small personal area networks (PANs). It can link up to eight devices within a 10-meter area using low-power, radio-based communication and can transmit up to 722 Kbps in the 2.4-gigahertz (GHz) band.
Detailed explanation-2: -Bluetooth is a standard protocol for short-range radio communications between many different types of devices, including mobile phones, computers, entertainment systems and other electronics.
Detailed explanation-3: -While technically 802.11ac does NOT support 2.4 GHz bands, in practice most 802.11ac routers are dual-band and can fallback to 802.11n if needed. Good choice for most modern (late 2020/early 2021) devices and networks. Decent speeds and many modern devices have 802.11ac compatible Wi-Fi radios.
