Bluetooth vs. Wi-Fi Bluetooth File Exchange is a utility that comes with the Mac OS X operating system, which is used to exchange files to or from a Bluetooth-enabled device. Wi-Fi is a wireless version of a common wired Ethernet network, and can require configuration to set up shared resources, transmit files, and to set up audio links (for example, headsets and hands-free devices). Wi-Fi will use the same radio frequencies as Bluetooth, but with higher power, resulting in higher bit rates and better range from the base station. The nearest equivalents in Bluetooth is the DUN profile, which allows devices to act as modem interfaces, and the PAN profile, which allows for ad-hoc networking. Bluetooth and Wi-Fi have some similar applications: setting up networks, printing, or transferring files. Wi-Fi can be intended as a replacement for cabling for general local area network access in work areas. This category of applications may be sometimes called wireless local area networks (WLAN). Bluetooth was intended for portable equipment and its applications. The category of applications can be outlined as the wireless personal area network (WPAN). Bluetooth is also a replacement for cabling in a variety of personally carried applications in any setting and also works for fixed location applications such as smart energy functionality in the home.
