The paper " A Brief Explanation of Bluetooth Technology" is a wonderful example of a term paper on information technology. Bluetooth technology is an open standard used for short-range radio frequency communication between two or more devices. Bluetooth connection enables a formation of a Wireless Personal Area Network (WPAN) which is essentially known as an ad hoc network or a peer-to-peer (P2P) network. Bluetooth technology has found usage in a wide range of devices including cellular phones, laptops, automobiles, personal digital assistants and headsets. It is thus possible to form an ad hoc network between many different devices and create a wireless file-sharing process because of the Bluetooth interoperability (Scarfone 2).

Bluetooth also enables secure voice and data transfer between devices that are Bluetooth enabled. When two or more devices are connected creating a Bluetooth network, is usually referred to as a piconet. Bluetooth standardization is within IEEE 802.15 Working Group used in Wireless Area Networks which was created in 1999 and thus considered IEEE 802.15.1-2002. The frequency range of Bluetooth is about 2.4 Gigahertz (GHz) which is unlicensed. Because this range of frequency is crowded, Bluetooth implements a frequency hopping spread spectrum (FHSS) to transmit data and voice (Minoli 309).

FHSS minimizes transmission errors, interferences and also provides a considerable level of transmission security. Bluetooth is also capable of radio link power control which allows devices to regulate their radio power according to the desired signal levels as measured. Basic components making up Bluetooth wireless specification There are many components that make up a Bluetooth wireless specification, some of the fundamental components of this wireless specification are as elaborated below. The host- hosts can be a variety of devices but they are mainly computers and laptops that are specifically responsible for the higher levels of the Bluetooth stack architecture which includes; the Logical Link Control and Adaptation Protocol (L2CAP) and the Service Directory Protocol (SDP). The host controller – this can also be a variety of devices such as Bluetooth dongle, the host controller is mainly responsible for the management of the lower levels such as the RF-Baseband and the Link Manager Protocol (LMP). The Host Controller Interface (HCI) - this is an interface that is essentially managing the link between the host and the host controller.

It is also important to note that there are devices that integrate the host and the host controller in the same device; examples of such devices are Bluetooth handset. The Radio link and the Baseband are also imperative components of the Bluetooth because the baseband layer allows the physical RF link between two units in a piconet. The baseband layer is especially responsible for maintaining the formatting and addressing of packets. The two types of baseband layers are Synchronous Connection-Oriented (SCO) and Asynchronous Connectionless (ACL) (Bagad 21). Benefits of Bluetooth wireless Convenience Bluetooth devices create convenience as it eliminates the need for cables to connect devices such as mobile phones and notebooks.

This is specifically important in a business trip as the traveler worries less about the cables since a wireless synchronization can be enhanced via Bluetooth technology. Most importantly a Bluetooth user can easily create a connection to the internet without using any cable because the Bluetooth standard allows for internet connection via Bluetooth.
