1.0 Introduction
Low Energy Bluetooth, Bluetooth LE, or BLE, marketed as Bluetooth Smart, is a wireless personal area network technology designed and marketed by the nonprofit, non-stock corporation Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, security, and home entertainment industries. Compared to "Classic" Bluetooth, BLE is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range.
Bluetooth LE was originally introduced under the name Wibree by Nokia in 2006 It was merged into the main Bluetooth standard in 2010 with the adoption of the Bluetooth Core Specification Version 4.0.
Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X and Windows 8, natively support Bluetooth low energy. The Bluetooth SIG predicts more than 90 percent of Bluetooth-enabled smartphones will support the low energy standard by 2018

Table 1 : Low energy Bluetooth Capabilities
1) Bluetooth low energy is about transferring state
• small, infrequent bits of data
• lowest possible power consumption
• lowest latency
2) Splits the 2.4 GHz ISM band into 40 channels
• 3 Advertising Channels
• 37 Data Channels
• fn = 2402 + 2n MHz
3) GFSK Modulation
• Modulation index 0.5, giving better range than classic Bluetooth
• allows use of fewer advertising channels
• reduces power consumption
• increases connection speeds
• Can reuse existing RF parts in a Bluetooth chip
• Minimal additional cost in dual-mode chips
I am like every Smartphone user that can probably make it through the day on a single charge, but not without a degree of caution, by keep Bluetooth turned off when it’s not in use, and avoid long stretches of data use over 4G. High-end games and streaming video are guaranteed to melt away battery life, and if i am spending a few hours in a dead zone, I better off powering down instead of wasting precious juice searching for a signal.
Anticipate the moment at which all your personal electronic devices - headphone audio player, cellular telephone, pager, dictaphone, camcorder, personal digital assistant (PDA), electronic stylus, radiomodem, calculator, Loran positioning system, smart spectacles, VCR remote, data glove, electronic jogging shoes that count your steps and flash warning signals at oncoming cars, medical monitoring system, pacemaker (if you are so unfortunate), and anything else that you might habitually wear or occasionally carry - can seamlessly be linked in a wireless bodynet that allows them to function as an integrated system and connects them to the worldwide digital network.

With the recent popularity and introduction of various products such as the Fitbit, Garmin’s Vivoactive, and Android’s smart watches, Apple releasing the Apple Watches definitely kept up with the smart watch trend. The Watch’s massive presence in the market has allowed it to not only match many of the qualities of other watches, but in a way surpass them with the apps, and marketing programs it has implemented into the design and functionality of the Watch.
On April 3, 1973, Martin Cooper, a Motorola engineer, proudly held the first cell phone making the first call on the cellphone ever. Today smartphones are so popular, that nearly 75 percent of Americans have one. These phones, tablets, smartwatches aren’t just devices, but treated like best friends. This small invention in the 1970’s has now turned the smartphone market into half a billion dollars. This device that we love so much was actually inspired by Star Trek, a famous American science-fiction television series.
As we progress deeper into the digital era, we rely more and more on our electronic devices. Over the last decade, almost everyone who lives in a developed nation owns a cellphone and they are becoming an integral part of our life.
Nike has found a way to make smart phones work with a bracelet to track all of your physical activity each and every day. Now that is sweet, not is Nike making great sporting and everyday clothes, but they now have found a way to make your phone ...

Dr. Jaap Haartsen, a Dutch Engineer, while working at Ericsson in Europe invented Bluetooth in the 1990's. Bluetooth was originally developed as a wireless alternative to data cables. By the 21st century, several manufacturers saw the potential of Bluetooth and began to incorporate them into the designs of their products, mobile phones, and computers. In the 21st century, Bluetooth had become a part of our daily lives that allows us to become more mobile.
As per the Bluedouche principle, wearing a technological device would also be sending social message to the people and this can hinder the growth and usage of wearable devices. The author cites the case of hindered growth of earpieces as wearing earpieces all day used to send a lame message to the society. Wearing these devices all day can end up in sending messages that the user does not want to send. For example, if a salesperson wears earpieces all day, it may give the impression that the person is too occupied in his or her work that he or she does not have time for personal enjoyment. It may also give the idea that the person is trying to show off and is acting lame. The similar concept is applicable with wearable technology also. If a person is wearing a particular device every time, that can also impact the social image of the person. I agree with the author on this limitation and it is important the mindset of the people changes to accept the all-time use of wearable devices. It is not feasible for the person to take off the device when not in use and plug it again as that would be time consuming and can also make the process of using weara...
Important feature of wearables is to provide a context sensitivity: the device may become aware of information that are strictly personal, the user's surroundings and personal state.
In the mid-2000s, many other phone manufacturers including Dopod, Palm, HP (Hewlett-Packard), and Sony start to introduce touch-base smartphone pre-installed
There are already several wearable devices available in the market, mainly divided into two kinds. The health monitoring wristband, such as UP by Jawbone, Fitbit Flex, Nike Fuelband, etc. provide real-time tracking of users’ movement, sleeping and calories consuming. Meanwhile, smartwatches, like Galaxy Gear from Samsung, are only provide basic watch functions and some basic control of few specific smartphones. With a return rate over 30% of Galaxy Gear [1], it is obvious that such so-called smartwatch cannot attract consumers as well. Here is the problem: these two kinds of devices are designed independently and customers are tired of having so many devices on their wrists. Besides, relatively high prices (about 100 USD) prevent lots of potential consumers from purchasing a single function wristband only for health. People also complain the terrible battery life and simple function of smartwatch.
Bluetooth technology was intended to hasten the convergence of voice and data to handheld devices, such as cellular telephones and portable computers. Through the efforts of its developers and the members of the Bluetooth Special Interest Group (SIG), it is now emerging with features and applications that not only remain true to its original intent, but also provide for broader uses of its technology.
... software in terms of the device contains the small computer chip with the Bluetooth on it but it needs software to connect to via Bluetooth. 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.
