For example, through Bluetooth technology, one is able to talk on a mobile phone via a wireless headset, update an appointment on a friend’s PDA calendar from personal PDA or operate a computer via a wireless keyboard. Bluetooth enabled devices are equipped with their own complete software framework and protocol stack that enable them to disseminate data to other devices within a close range (Minoli 308). History of Bluetooth Technology The origin of Bluetooth can be traced to 1998 when the Bluetooth Interest Group (SIG) was created and Bluetooth adopted as the official name of the resulting technology. In 1999, Bluetooth Specification 1.0 was released leading to declaration of Bluetooth as the Best of Show Technology by COMDEX (Minoli 308). Shortly after in the year 2000, the first Bluetooth enabled mobile phone, PC card, headset, laptop, and mouse as well as USB dongle prototype were launched at COMDEX. The following year, the Bluetooth SIG Inc was established and followed immediately with the launch of the first hands-free Bluetooth enabled car kit. This was followed by the launch of the first Bluetooth enabled digital camera and the first GPS receiver in 2002. In the same year, the IEEE (Palanivelu and Nakkeeran 180) approved 802.15.1 specification for Bluetooth. The first Bluetooth based MP3 was unveiled in 2003, the same year when the FDA gave the green light for Bluetooth controlled medical system. The Enhanced Data Rate (EDR) was adopted in by the SIG Inc, in 2004 alongside 250 million Bluetooth embedded devices and stereo headphones. The greatest breakthrough came in 2006 when Bluetooth was installed in over one billion devices. Contemporary research focuses on employing the advantages of the Bluetooth technology in the healthcare domain, whereby individuals will be able to rely on Bluetooth enabled wireless devices to keep track of their body temperature, metabolism rate and pressure count (Palanivelu and Nakkeeran 180). These devices will through Bluetooth transmission collect important health information from patients then share them with a doctor through a PC or a cellular phone. Goals of the Bluetooth Technology Bluetooth technology was intended to provide solution to the problems inherent in infrared systems that was already in use in most television remote sensing control systems. While infrared is reliable and fairly less costly, the devices rely on line of sight technology requiring the receiver device to be within a pointing range (Palanivelu and Nakkeeran 181). This means that infrared cannot be used across walls or to control devices in different rooms even if they are all within a sensing range. There was therefore need for a wireless technology that could be relied on to operate several devices simultaneously in the absence of line of sight, which made Bluetooth more appropriate. Additionally, the Bluetooth technology was the most ideal technology that would provide wireless interactivity/connectivity between two paired devices at low frequency and with minimum interference (Palanivelu and Nakkeeran 181). Other significant goals for devising the technology included managing cross device communication at low power, low cost and dynamic networking for mobile devices How Bluetooth Works Bluetooth networking system transmits data through low power radio waves, enabling communication at a remote frequency of about 2.45gigahert. The low frequency

Data like videos, pictures, music, information and voice can be transferred easily between the two paired devices over a short distance and that to within seconds. Wireless signals transmitted by Bluetooth cover short distances up to 30 feet. These signals communicate less than 1 Mega Byte per second (1 Mbps).
The SIG group felt that the name Bluetooth was befitting because they used the same concept like King Bluetooth. Bluetooth technology has the ability to unite different industries like the mobile phone, computing and automotive industries.
IrDA is another wireless communication technology with certain beneficial features. However, it has sizable disadvantages. Bluetooth scores over IrDA in those aspects as well as other additional features. At the same time, Bluetooth has certain disadvantages as well, but those limitations can be managed.
Bluetooth uses Gaussian Frequency Shift Keying (GFSK) modulation in its basic mode. GFSK is a frequency shift keying modulation that smoothes negative/positive frequency deviations using a Gaussian filter. The average number of bits or characters that can be transmitted per unit time by Bluetooth can reach up to a rate of 1Mb/s.
Now, the communication technology available to us is greatly advanced and far ahead, allowing many nations rapid progress. Short range communication has assumed great importance now as better and faster mediums are sought. Three such short range communication mediums are cable, Infra red and Bluetooth technology.

In today's society, this technology implementation at business section simplifies in sending or receiving a fax, virtual business meeting, working collaboration, initiate a print-out and also the facility of the fixed computer devices complete coordinated.
In other words, it allows you to link devices without cables in the area of up to 10m surrounding an individual.
1. The Bluetooth standard can be added to many portable devices, such as laptops or personal digital assistants (PDAs), through the addition of specialist
Bluetooth can be termed as an innovative wireless technology; Bluetooth SIG (2010) states that it was developed in the late 1990s. ADCOMBHS highlights the historical developments of Bluetooth and states that nine major companies that dealt with communication and computers decided to join hands to support this technology.
ersonal computers, printers, telephones, laptops, GPS receivers, video game consoles and digital cameras including others for different practical operations as noted by Minoli (307).
Originally, Bluetooth was used in linking headsets to a mobile phone. Later it started being
