Introduction to Bluetooth Technology

The invention of the Bluetooth was a breakthrough in wireless data transfer technology since it allowed faster wireless transmission of data and over longer distances as compared with infrared technology (Wells, 2009). This made the data transmission easier and faster than it used to be before and more convenient for ordinary users. This is mainly why the technology became popular so quickly. Bluetooth has become a standard in wireless technology for the exchange of data over short distances (Stallings, 2005).

It uses short-wavelength radio transmissions from mobile as well as fixed devices that are in the ISM band between 2400 and 2480 MHz. This creates a type of PAN (Personal Area Networks) that ensures safe and secure data transfer. The technology was created in 1994 by Erickson, a renowned name in the global telecommunications industry and a leading telecom vendor. Erickson originally came up with the technology as a more portable substitute for RS-232 data cables since it supports wireless data transfer (Stallings, 2005). It allows connection with numerous devices at the same time, thereby overcoming issues associated with synchronization.

Components of Bluetooth

A Bluetooth device contains the following components:


This part of the Bluetooth framework is the methods by which information is sent and accepted to the Bluetooth framework (Stallings, 2005). The framework is designed to manage connections remotely. Clients must set their host mechanism to appropriate the particular recurrence; without it, Bluetooth does not work.

Baseband Microprocessor

This is the part of the Bluetooth framework that methods the information sent along the radiofrequency (Wells, 2009). The capacities of the baseband microchip are took care of with the connection controller that "sends and gains information, recognizes the sending unit, performs validation, and confirms the sort of edge to utilize for sending transmissions," as per Bakker and McMichael.


Memory is needed in the framework to keep the programming system and to uphold the settings for the framework (Wells, 2009). It is moreover needed to look after the qualified information that the client decides on to store.


The last segment for a Bluetooth framework is an interface to a host gadget. This is for the most part a cell telephone, however it may moreover be a workstation (Wells, 2009). The client imparts by way of the baseband to the host unit where the operations are led.

Protocols of Bluetooth

Bluetooth protocol stack

Bluetooth is demarcated as a layer order structural engineering comprising of center methodologies, link swap orders, telephony control methodologies, and received methodologies (Wells, 2009). Compulsory methodologies for stacks of Bluetooth are: L2CAP, LMP, and SDP. Moreover, gadgets corresponding with Bluetooth devices just about all around can utilize these orders: RFCOMM and HCI.


The LMP (abbreviation for Link Management Protocol) is utilized for situated-up and regulation of radio connections in between 2 mechanisms (Wells, 2009).


AVRCP stands for Audio and Video Remote Control Profile and is generally present in cars that use automobile car navigation technology for controlled streaming of Bluetooth audio (Wells, 2009).
