What is blue tooth? What are the functions? Please descibe.?

Question

Some blue tooth facilities on mobile phones. Blue tooth conecting to computer to get connection with mobile. Hands free set for mobile also working with blue tooth principle. So could you please tell me how does that works the blue tooth and what are the functions? how it look likes?

Answer 1

Look around you at the moment, you have your keyboard connected to the computer, as well as a printer, mouse, monitor and so on. What (literally) joins all of these together?, they are connected by cables. Cables have become the bane of many offices, homes etc. Most of us have experienced the 'joys' of trying to figure out what cable goes where, and getting tangled up in the details. Bluetooth essentially aims to fix this, it is a cable-replacement technology
Conceived initially by Ericsson, before being adopted by a myriad of other companies, Bluetooth is a standard for a small , cheap radio chip to be plugged into computers, printers, mobile phones, etc.A Bluetooth chip is designed to replace cables by taking the information normally carried by the cable, and transmitting it at a special frequency to a receiver Bluetooth chip, which will then give the information received to the mouse, keyboard, computer, headset, cell phone whatever.

The Problem

When any two devices need to talk to each other, they have to agree on a couple of points before the conversation can begin. The first point of agreement is physical: Will they talk over wires, or through some form of wireless signals? If they use wires, how many are required -- one, two, eight, 25? Once the physical attributes are decided, several more questions arise:

* How much data will be sent at a time? For instance, serial ports send data 1 bit at a time, while parallel ports send several bits at once.

* How will they speak to each other? All of the parties in an electronic discussion need to know what the bits mean and whether the message they receive is the same message that was sent. This means developing a set of commands and responses known as a protocol.

Bluetooth is essentially a networking standard that works at two levels:

* It provides agreement at the physical level -- Bluetooth is a radio-frequency standard.

* It provides agreement at the protocol level, where products have to 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.

Now, as far as power and charging issues...

The Bluetooth Solution
Bluetooth takes small-area networking to the next level by removing the need for user intervention and keeping transmission power extremely low to save battery power. Each transmission signal to and from your cell phone consumes just 1 milliwatt of power, so your cell phone charge is virtually unaffected by Bluetooth activity.

By the way if, you're wondering where the Bluetooth name originally came from, it named after a Danish Viking and King, Harald Blåtand (translated as Bluetooth in English), who lived in the latter part of the 10th century. He managed to unite Denmark and part of Norway into a single kingdom then introduced Christianity into Denmark. He was killed in 986 during a battle with his son, Svend Forkbeard. Choosing this name for the standard indicates how important companies from the Nordic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry, even if it says little about the way the technology works.

I hope this helps!

Answer 2

BlueTooth is a specification for using low-skill radio communications to wirelessly link phones, pcs and different community contraptions over short distances. The call "Bluetooth" is borrowed from Harald Bluetooth, a king in Denmark more suitable than a million,000 years in the past. Bluetooth technologies change into designed ordinarily to help common on the spot networking of non-public customer contraptions and peripherals, such as cellphones, PDAs, and on the spot headsets. on the spot signals transmitted with Bluetooth hide short distances, typically as a lot as 30 ft (10 meters). Bluetooth contraptions oftentimes communicate at lower than a million Mbps.

Answer 3

A standard technology being developed by a consortium of large IT and communications firms that allows computers, computer peripherals, and certain household appliances to communicate with each other over shortish distances without the need for connecting cables. They use short-wave radio frequencies. Examples include a PC sending a file to a printer.

Answer 4

http://en.wikipedia.org/wiki/Bluetooth

plz take a peek into this...

in laman's term - Bluetooth is a way of connecting various devices wireless. (within a short distance )

there are other forms also.. infrared ( ver short distace) blue tooth relativeily for wider area and WI-FI - even for wireless internet...

Answer 5

Bluetooth is a function where people can exchange ringtones and wallpapers but it's fun. I heard that if you leave bluetooth on your battery is gonna get wasted, so when you leave bluetooth on your battery is gonna waste and you don't want that to happen.

Answer 6

I looked it up, and it said something about getting
in through your wireless connection.
I want to delete mine. I don't use it.
