Bluetooth and Wi-Fi wireless technology - Assignment Example

Bluetooth and Wi-Fi wireless technology Bluetooth Technology Origin Bluetooth s back to 1996 when Nokia’s low-power RF, Intel’s Biz RF, and Ericsson’s MC-Link were united by SIG and related to King Harald Bluetooth’s unity to Scandinavia (Bluetooth Technology n.p).Operation It is a universal and accepted wireless protocol facilitating communication between two devices, such as two personal computers, mobile phones, and personal digital assistants (PDAs), using radio frequency. Bluetooth permits devices’ interconnectivity with each other, or with business and home computers and phones, through restricted wireless links of between 10-100 meters at speed of 1 Megabit in every second (Walters 12).

Frequency Devices interconnectivity facilitates Local Area Network or LAN-like abilities that make linking easier with safe and expedient transmissions. 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.

The origin dates back to 1985 after the United States Federal Communications Commission (FCC) freed the ISM band for unlicensed use.Operation 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. FrequencyLike 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 802.11n.Works CitedBluetooth Technology. Bluetooth Basics. 2014. Web. 31 August 2014. Rackley, Steve.
