What Could Bluetooth Wireless Speaker Taken? --- Wireless Convenience of A Wonderful Experiences!



Era of smart mobile terminals is coming, they have become more and more popular and fashion product, such as IPHONE, IPAD and many Android smart phone and tablet computer and gradually Bluetooth system has also become a standard configuration of the mobile terminal. Those mobile terminal device achieve a trend to integrate a great music, video, games and other application functionality, and even mobile phones and other portable digital products could not been taken away from our daily lives. For example, online map, microblogger, e-mail, instant messaging is a typical example. From begining in 2011, main manufacturers of speaker have begun to enter the market segments of Bluetooth wireless speaker. Shenzhen Wistao Technology (http://www.wistao.com) had developed different series of Bluetooth speaker through market research to grasp trend of Bluetooth product development.

For such handheld portable devices of smart phone or tablet, wired speaker is clearly inappropriate due to highly mobile, but it will be more comfortable to use Bluetooth wireless speaker.

With Bluetooth wireless speakers, what can we do indeed? Take a look, and share it!

A.   When you get together with friends, or are picnic on the country side, or take leisure time and do exercise, you can use your phone to play the music, but it will reduce acoustics of music greatly. However, Bluetooth speakers, you can enjoy the beautiful, first-class sound quality of music without cable connection, also you do not have to worry about the battery problem.
B.   Share network radio like as BBC music, CNN radio, WIN7 Internet radio, etc. Together better than alone, when we would like to share our collection of music at the party, you will first think of the speakers, Bluetooth speakers must be the best choice at this time, almost without limit by distance indoors . In this way, you can not endure the bad phone or laptop sound.
C.   High quality of game experiences for all games almost. At beginning, games of mobile phone just to design to kill time only, but today's mobile games have been very strong functions with hardware to enhance the level. Not only from visual effects and sound but also game-playing do reach a very high level. And like as Gameloft and Popcap companies, They had been released a large number of outstanding game for smart phones or tablets. In addition, such as the music game as DJMax, it also will demand a higher sound output.
D.   Suitable for mobile television demand (Thunder, You Tube, Sina video, etc.). Online movies and TV series has also become one of the important functions of the portable devices, because of online video software easy to use, many people return home and use iPad or smart phone to watch video instead of computer. This operation has two advantages, one is to simplify operation between speaker and amplifier, another advantage is that you can curl up on the couch or lie in bed or sit at desk. Using mart phone or tablets is certainly much more convenient than computer, this arbitrariness is obviously not suitable for wired speakers.
E.   Hands-free answering the phone. Avoid prolonged to answer phone calling, and the impact of the hearing, while reducing smart phone radiation. Also, liberate your hands while call is coming.
F.    May be used to hold a conference call. The clear call feature can be used to hold a conference call.

IPHONE5 Adopt Bluetooth 4.0 Technology

IPHONE5 Adopt Bluetooth 4.0 Technology




Bluetooth v4.0 is the wireless connection in new iPhone 5, iPod nano and iPod touch; Global rollout accelerating adoption of Bluetooth Smart Ready hubs.

Apple announced the addition of three new products into the Bluetooth v4.0 ecosystem - the highly anticipated iPhone 5, iPod nano and iPod touch. The iPhone 5 and iPod touch are Bluetooth Smart Ready hubs, making it possible for a wide-range of devices from a mobile phone to a sensor device like Nike’s new Hyperdunk+ basketball shoe or Polar’s H7 heart rate strap, to connect, collect and share information in real-time. The easy and reliable connection supplied by Bluetooth technology enables the three new Apple devices to communicate securely with the more than seven billion Bluetooth-enabled devices already on the market. 

“Bluetooth v4.0 is the only wireless technology available today that provides low energy consumption, security, performance and the massive installed base manufacturers need to create, innovate and enhance the usability of their products,” said Suke Jawanda. Apple knows it – in today’s keynote the company called out Bluetooth technology as one of the biggest requests for the iPod nano. Our 16,500 member companies also know it. To make the wireless connectivity of your product better, the clear and obvious choice is to use Bluetooth.”

Today’s Apple announcement also highlighted the company’s aggressive global rollout plans for its new products, placing Bluetooth Smart Ready hubs in the hands of more consumers and ensuring that developers will have even more incentive to make their products better with Bluetooth. By adding Bluetooth v4.0 to the new iPhone 5, iPod touch and iPod nano, Apple not only gives consumers the ability to stream high fidelity music to speakers and earphones, but also connect to thousands of new ultra power efficient Bluetooth Smart products like watches, training shoes and heart rate monitors. This connectivity is the convenience that Bluetooth provides to consumers and the opportunity that Bluetooth v4.0 presents to developers. No other wireless technology comes close to providing the convenience, ubiquity and performance that Bluetooth provides. 

“Adoption rates of Bluetooth v4.0 are rapidly increasing in the smartphone, laptop, and tablet markets, creating hundreds of millions of Bluetooth Smart Ready hubs,” said Peter Cooney, wireless connectivity practice director at ABI Research. “Apple is at the heart of this revolution adding Bluetooth v4.0 to many of its products including the iPhone 4S, iPad 3, Mac Mini, and Macbook Pro and Air laptops. It has increased its Bluetooth Smart Ready Hub portfolio with its iPhone 5 and new iPod devices, further showing its commitment to the technology. This will be a major boost to Bluetooth Smart market growth over the coming years.”



Basics of Bluetooth Wireless Technology

Basics of Bluetooth Wireless Technology




Bluetooth technology is a short-range communications technology that is simple, secure, and everywhere. You can find it in billions of devices ranging from mobile phones, laptops, tablets and computers to medical devices and home entertainment products. It is intended to replace the cables connecting devices, while maintaining high levels of security.

The key features of Bluetooth technology are robustness, low power, and low cost. The Bluetooth Specification defines a uniform structure for a wide range of devices to connect and communicate with each other.

When two Bluetooth enabled devices connect to each other, this is called pairing. The structure and the global acceptance of Bluetooth technology means any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices located in proximity to one another.

Connections between Bluetooth enabled electronic devices allow these devices to communicate wirelessly through short-range, ad hoc networks known as piconets. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity meaning that you can easily connect whenever and wherever it's convenient for you.
Each device in a piconet can also simultaneously communicate with up to seven other devices within that single piconet and each device can also belong to several piconets simultaneously. This means the ways in which you can connect your Bluetooth devices is almost limitless.
A fundamental strength of Bluetooth wireless technology is the ability to simultaneously handle data and voice transmissions. which provides users with a variety of innovative solutions such as hands-free headsets for voice calls, printing and fax capabilities, and synchronization for PCs and mobile phones, just to name a few.

The range of Bluetooth technology is application specific.The Core Specification mandates a minimum range of 10 meters or 30 feet, but there is no set limit and manufacturers can tune their implementations to provide the range needed to support the use cases for their solutions.

Bluetooth Core Specification
Unlike other wireless standards, the Bluetooth Core Specification provides product developers both link layer and application layer definitions, which support data and voice applications.

Spectrum
Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. The 2.4 GHz ISM band is available and unlicensed in most countries.

Interference
Bluetooth technology's adaptive frequency hopping (AFH) capability was designed to reduce interference between wireless technologies sharing the 2.4 GHz spectrum. AFH works within the spectrum to take advantage of the available frequency. This is done by the technology detecting other devices in the spectrum and avoiding the frequencies they are using. This adaptive hopping among 79 frequencies at 1 MHz intervals gives a high degree of interference immunity and also allows for more efficient transmission within the spectrum. For users of Bluetooth technology this hopping provides greater performance even when other technologies are being used along with Bluetooth technology.

Range
Range is application specific and although a minimum range is mandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling. 
Range may vary depending on class of radio used in an implementation:
  • Class 3 radios – have a range of up to 1 meter or 3 feet
  • Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 33 feet
  • Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet
Power
The most commonly used radio is Class 2 and uses 2.5 mW of power. Bluetooth technology is designed to have very low power consumption. This is reinforced in the specification by allowing radios to be powered down when inactive.

The Generic Alternate MAC/PHY in Version 3.0 HS enables the discovery of remote AMPs for high speed devices and turns on the radio only when needed for data transfer giving a power optimization benefit as well as aiding in the security of the radios.

Bluetooth low energy technology, optimized for devices requiring maximum battery life instead of a high data transfer rate, consumes between 1/2 and 1/100 the power of classic Bluetooth technology.
