Q.Compare Wi-Fi with Bluetooth.

Wi-Fi and Bluetooth are both wireless technologies in the 2.4 GHz region, but they are built for different jobs — Wi-Fi for high-speed network access and Bluetooth for simple short-range links. …

[!TLDR]

Wi-Fi is an access-point-based, high-speed, longer-range network technology; Bluetooth is a symmetrical, short-range, low-configuration link between two devices.

Wi-Fi and Bluetooth are compared as follows:

• Connection type: Wi-Fi is usually access-point-centred, giving an asymmetrical client-server connection that is routed through the access point (AP). Bluetooth is usually symmetrical, forming a direct link between two devices.
• Configuration: Wi-Fi suits applications that need client configuration and high speeds for network access. Bluetooth serves simple applications that need only minimal configuration, such as headsets and remote controls.
• Frequency and range: Wi-Fi uses the 2.4 GHz and 5.8 GHz bands and reaches up to about 100 m. Bluetooth uses the 2.4 GHz ISM band and works only over a short range.
• Ad-hoc use: both Bluetooth access and ad-hoc Wi-Fi connections exist, but setting up an ad-hoc Wi-Fi link is not as simple as a Bluetooth connection. …
