1. An introduction
What is Bluetooth ? Bluetooth is a connecting device that well known among people all around the world. It allows you to talk and share information such as music, voice and video wirelessly. Bluetooth technology uses radio waves just like mobile phones, TV and FM radio.The difference between these device and Bluetooth wireless technologies is the distance because it sends information only to your personal area.
About the history, the military discovered the technology used by Bluetooth turns was in 1940 pioneers. Engineers in a Swedish company called Ericson Bluetooth technology invented in 1994. A group of companies in 1998, worked together to connect their products using Bluetooth technology. Seeing that the technology worked, companies formed the special interest group (SIG) Bluetooth. This organization is dedicated to keeping this technology. Bluetooth technology is not possessed by a single company, but the members of the Bluetooth SIG all work together to develop the technology.
Bluetooth intended originally to substitute for cables and wires between things like mouse and keyboard computer. Although it works great in these types of devices, it also can connect to televisions, music players and homecare devices.
While Bluetooth technology is growing, anyone can create a connection. Cable and wire You can now connect your mobile phone to the car stereo, or print pictures from your camera phones, Bluetooth technology allows you to check your pulse. Speed and steps as you work out jogging walking or running a company 13000, rather than develop innovative products that use Bluetooth technology, product innovation, this range but wacky reach and promise to make our lives easier and more fun.

Nowadays, people seek a simplest and fastest ways to send file and Bluetooth act as one of it. This is because the technologies have improved and Bluetooth also can upgrade by time. The speed, range and specification can be repaired and improved as long people using it.
As a conclusion, Bluetooth is a connection between two device it is used worldwide.

This is the circuit diagram for the Bluetooth module that we are planning to use. What we have to do for Bluetooth circuit is connect pin 8 from the analog switch into the transmitter (TX). The next step is to connect pin 17 from the encoder into the receiver (RX). This will send the outputs from the switch and the encoder into the Bluetooth circuit and from where we can have it send out a notification to a cellular phone or anything that can receive Bluetooth messages.
Smart phones have dramatically changed the way we communicate. I know for certain that after seeing my friends during the day that when I get home I can immediately text them or snap chatting or any of the ways we communicate. I can’t imagine living in a world without being able to communicate with my friends across the room or across the globe at the click of a button. Sitting in my room I can check the news, play a game and talk to my friend in America all at the same time. The technology has advanced so much since the first iPhone. Along with other smart phones they have changed the way we communicate because we can just pick up the phone and talk to someone and you can text a question or facetime them. Smart phones have changed the world because at the tips of your fingers anywhere you can check the weather, watch a video, listen to music, take a picture, get directions, check the time, get information from the internet and watch your favorite TV show.
Bose Corporation is global and this enhances the private company in a big way. Some of the new devices Bose implemented are: New Bose QuietComfort 20 and 20i, Acoustic Noise cancelling and New Bose SoundLink Mini Bluetooth speaker all available July 11, 2013 (Business Wire, 2013). The Bluetooth is owned by Bluetooth SIG, Inc. and license under Bose Corporation. Since the corporation is global, this will give the company more of an opportunity to stay relevant to the business.
Every invention ever known to man had pioneers or people who contributed to the creation of the product. Radio had many pioneers that allowed for its creation and their names are Heinrich Hertz, Nikola Tesla, Ernst Alexander, Edwin Armstrong, Guglielmo Marconi, Lee DeForest, Frank Conrad, Reginald Fessenden, and Edward Armstrong. It all started with a German physicist named Heinrich Hertz who in 1884 proved that you could transmit and receive electric waves wirelessly. Hertz thought that the work he had done had no use whatsoever but little did he know that what he done is considered the fundamental building block of radio, and that is the reason why every frequency measurement is named after him (Short). In that same year a Serbian-American inventor named Nikola Tesla came to the U.S and sold patents to his inventions to a man named George Westinghouse. After that Tesla established his own lab which is where he built the tesla coil , an induction coil that is still used in radio today (Short). The next progression of radio focused on more than just the transmission of waves, the new focus was transmission of speech. The first to begin to add speech into the radio mix was Ernst Alexander, a Sweden born inventor who developed the first alternator to make speech transmission possible (Short). This was so new to the s...
Cell phone technology dates all the way back to 1947. “In that year researchers first developed ideas as to the possibility of creating mobile phones that used "cells" that would identify a user in whatever specific region he or she was initiating the call from” (Cell Phone World). Still the technology was very limited at the time, so much more extensive research was required. In 1968 private companies started getting involved with cell phone development, such as AT&T. The FCC (The Federal Communications Commission) then opened new frequencies and the private companies had the theory of cellular towers. Each tower would be responsible for a particular region. When a customer traveled farther a way from one region it would switch the call to a closer tower with no interruption. In 1977 public cell phone testing had begun. People in Baltimore, Chicago, and Washington were the first to be eligible for cell phone trials. In 1979 a company in Japan began doing cell phone testing with the public. Not until 1983 were cell phones really available. “The year 1988 changed many of the technologies that had become standard in the past. The Cellular Technology Industry Association was created to set realistic goals for cellular phone providers and research new applications for cell phone development” (Cell Phone World). In a way they still were not very accessible to the public, due to their extremely high operating cost to the consumer. Only the very wealthy could afford cell phones. Important heads of cooperation’s, movie stars, and top government officials were able to afford the luxury of a mobile phone.
The advancement of cell phone technology in the last decade is truly astounding because back then most people’s cell phones had such limited capabilities. Cell phones or smart phones as they are also known today have so many advanced abilities it’s more like having a pocket sized computer in your grasp. We can

Does the idea of using your body as a data transmission appeal to u? Then this paper will surely grab your attention. Technology is making many things easier; I can say that our concept is standing example for that. So far we have seen LAN MAN,WAN, INTERNET & many more here is new concept of “ RED TACTON ” which makes the human body as a communication network by name .... HAN (Human Area Network). Focusing on the naturalness ,inevitability and sense of security conveyed by touching which we call Redtacton [Red-Warmth ,T-Touch ,Acton-Action]which could let people transfer data to each others handhelds by means of handshake or a slap on the back. using a transmitter embedded in say , a PDA Redtacton sends a 5 volts pulse along the surface of body. The human body shunts most of electricity to ground resulting in weak electric field that can be modulated to carry signals .As the receiver is located either on another part of the body ,the components of a hand free handset or in an acquaintance PDA as it senses modulation in the electric field the receiver decodes them to recover the data, Human Area Network is an important over current wireless technologies such as Bluetooth because users can narrowly limit signal recipients rather than broadcasting to all devices within given range. Using Redtacton enable devices music from our digital audio player in your pocket would pass through your clothing and shoot over your body to headphones in your years. Instead of fiddling around with the cable to connect your digital camera to your computer you could transfer pictures just by touching the PC while the camera is around your neck and since data can pass from one body to another you could also exchange electronics business cards by shaking hands, trade music files by dancing cheek to cheek or swap phone numbers just by kissing. While a good idea, Redtacton unfortunately has no compelling applications that are not already available. It doesn’t work reliably and yet has also been experiencing face perception among the general public. In this paper we will discuss about Redtacton and its working states and application of Redtacton in various fields and we will our Redtacton with other technologies for Data Transmission and know about Human Area Network.
A small Bluetooth chip is inserted into a device, the chip replaces the cables and carries all the information normally carried by cables. Then the device transmits the information at a special frequency to a receiver Bluetooth chip via an antenna (made of copper wiring) attached on to the Bluetooth chip. The wave is produced by the movement of the electrons up and down in the antenna when data is transmitted from the master device. (Freeman, 2001) The Bluetooth chip and its antenna are shown in figure 1.

All types of technology ranging from medical and health devices like sensors to smartphones, PCs and tablets use Bluetooth technology which makes lives easier and efficient.
as the Internet, if not for wireless networks. Another use of wireless is in areas where cables simply can not be ran or can not be ran without many complications. Historical buildings, for example, make cabling difficult or impossible due to the old architecture where cabling was not anticipated. Busy areas are another reason for wireless. Reception areas, for instance, may have many people in the area all the time so cabling may not be practical. Another need is for people who are on the move. Good examples of this would be doctors or nurses who are going in and out of rooms and taking a lot of information quickly. Palm pilots using infrared technology, which we will discuss later, makes it possible for a doctor to have information about a patient or to find out possible medications all within a few seconds thanks to these devices. Isolated areas provide another need for wireless networks. In this case, there may not be the availability to link to the network through cables. An office in Alaska would be a good example of this problem. These are just a few examples of the many possible needs of wireless networks.
The cell phone, in today’s world most people own one. Cell phones are extremely convenient. They (cell phones) allow us to communicate in multiple ways. You can text, email, call, video chat, use social media apps to stay in contact with anyone anywhere.
A mobile phone is a telephone that can make and receive calls over a radio
There are different types of technology; the most common type is information technology, which includes smart phones, computers/laptops, GPS and many other devices. Smart phones make it easier to reach people by calling, texting, chatting, Snap chatting and even
