As a Wireless LAN, Bluetooth substitutes wired LAN and operate in unlicensed Industrial, Scientific and Medical (ISM) frequency group varying between 2.4 to 2.485 (Bluetooth Technology n.p). Operating within the ISM band involves utilizing broad spectrum, complete duplex, and frequency hopping signal at average speed of 1600 hops/sec with a 48-bit address from IEEE 802 standard.
Wireless Fidelity (Wi-Fi) technology sets-up computer networks through IEEE 802.11 to establish secure WLAN. The origin dates back to 1985 after the United States Federal Communications Commission (FCC) freed the ISM band for unlicensed use.
According to Walters (12), Wi-Fi provides extensions in wired LAN that lead to a wireless router. This router connects to WLAN devices to receive and transmit data within themselves or to the external environment. Unlike Bluetooth, Wi-Fi uses include larger campuses with tactically placed range extenders to broaden the signal. Newer Wi-Fi versions include 802.11n and 802.11ac, with rearward compatibility facilitating binding with older devices.
Like Bluetooth, WI-Fi operates in unlicensed radio spectrum at frequency bands of 2.4GHz and 5GHz (Rackley 60). The 802.11a router indoor range 115ft while outdoors in conducive weather is 390ft. For the 802.11b/g the range is 125 ft indoor and 460 ft outdoors. Each 802.11x standards have varying data transfer rates ranging from 20Mbps for 802.11a/g to 600Mbps for dual band or ...Download file to see next pagesRead More
