Mobile Phone Blue Tooth


BlueTooth is the technology which enables seamless voice and data connections between wide ranges of devices such as mobile to mobile, mobile to computer, and vise versa through short-range digital two-way radio. It is an open specification for short-range communications of data and voice between both mobile to mobile and mobile to stationary devices. Bluetooth is a wireless protocol that is used to communicate from one device to another in a small area usually less than 30 feet. The primary advantage of Bluetooth Technology is that it uses the 2.4 GHz Industrial Scientific and Medical (ISM) spectrum to communicate which is freely available in most of the countries. Bluetooth Technology allows the communication between two devices at a rate of 1 megabit connection between 2 devices for both a voice channel and a 768K data channel.

Prior to Bluetooth technology the only way to connect two devices such as a mobile phone to mobile phone or mobile phone to a computer or computer to computer was either via cables or infrared, both of these technologies had their own limitations. The first generation of Bluetooth permits the user to exchange data upto 1 megabits per second; even in areas which have very high amount of electromagnetic disturbance. It transmits and receives via a short-range radio link using a globally available frequency spectrum of 2.4 GHz.

Bluetooth Specifications define a short (around 10 meters) or optionally a medium range (around 100 meters) radio link capable of transmitting data as well as voice up to a maximum capacity of 720 Kb/s per channel.

Bluetooth technology is a low-cost radio solution providing links between computers, mobile phones, other peripheral devices and portable handheld devices, bluetooth can also be used for connectivity to the internet. Bluetooth eliminates the need to buy or carry cables for connectivity.

For the Bluetooth technology to work tiny microchips (incorporating a radio transceiver) are built into digital devices to make wireless connections between two devices.

Bluetooth is a short-range radio technology which is aimed to simplify communications between mobile devices and the internet. It is also aimed to simplify data synchronization between net devices and other computers. Products which have the Bluetooth technology inbuilt in them must be qualified and should pass interoperability testing by the Bluetooth Special Interest Group prior to there release.

Bluetooth depends on mobile devices equipped with a chip for sending and receiving information.

Since the past few years numerous devices for home, personal and business use have been presented in the market, however no widespread technology has been presented to address the needs of connecting personal devices in Personal Area Networks (PANs). Bluetooth technology fills in this important need for wireless communication. The ability to communicate both voice and data using wireless channel, which uses a standard low-power, low-cost technology that can be integrated in all kinds of devices for enablement of total mobility.

Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment - from computers and cell phones to keyboards and headphones - to make its own connections, without wires, cables or any direct action from a user.

Bluetooth is intended to be a standard that works at two levels:
• Bluetooth works of radio-frequency standard – i.e. it provides agreement at the physical level.
• Bluetooth technology can agree on when bits are sent, how many will be sent at a time and how the parties in a conversation can be sure that the message received is the same as the message sent.

Cell Phone Blue Tooth


Bluetooth is a short-range radio technology aimed at simplifying communications among Internet devices and between devices and the Internet. It is a computing and telecommunications industry specification that describes how mobile phones, computers and personal digital assistants can easily interconnect with each other and with home and business phones and computers using a short-range wireless connection. Bluetooth is a short-range radio technology aimed at simplifying communications among Internet devices and between devices and the Internet. It is a computing and telecommunications industry specification that describes how mobile phones, computers and personal digital assistants can easily interconnect with each other and with home and business phones and computers using a short-range wireless connection. Using this technology, users of cellular phones, pagers, and personal digital assistants will be able to buy a three-in-one phone. You can make it possible to use this phone as a portable phone at home or in the office, get quickly synchronized with information in a desktop or notebook computer, initiate the sending or receiving of a fax, initiate the sending or receiving of a fax, initiate a print-out. So basically you can have all mobile and fixed devices totally coordinated, thanks to Bluetooth technology. Fundamentals of Bluetooth Bluetooth is a standard developed by a group of electronics manufacturers that makes it possible for cell phone to make its own connections, without wires, cables or any direct action from a user using Bluetooth enabled phone. It is not just with cell phones even computers and more electronic devices can make their own connection using Bluetooth. Bluetooth is designed to be a standard that has two levels of working: 1] Bluetooth is a radio-frequency standard. It provides agreement at the physical level. 2] It also provides confirmation at the next level of communication, where products have to agree on when bits are sent, how many will be sent at a time and how the users in a conversation can be sure that there is no adulteration in the message received after it has been sent. There are more than 1,000 companies belonging to the Bluetooth Special Interest Group. Bluetooth communication has taken the place of wires for connecting peripherals, telephones and computers. This technology is very popular among the cell phone users. It has given the cell phone technology new heights and is proving its worth as time passes. There are many advantages to cell phone users for using Bluetooth technology: 1] Bluetooth does not require you to do anything special to make it work. The devices find one another and strike up a conversation without any user input at all. It will make your work very easy once you use it for establishing connection. 2] It is wireless. When you travel, you do not have to worry about any type of wires or arranging hands free connected to your cell phone. They are no more required. 3] It is cost effective. It is not all that expensive as compared to the work it can do for you and it will make communication through cell phone a pleasure. Bluetooth has overcome the limitation of infrared about the distance and reliability. As compared to infrared, Bluetooth can make communication possible over longer distances and Bluetooth is more reliable also. Products with Bluetooth technology must be qualified and pass interoperability testing by the Bluetooth Special Interest Group prior to release.
