Temily explains how you can get high quality music on mobile.

 

Over the past few years, I have developed the hobby of observing people from my car, especially those drivers who are alone but see to be engaged in deep conversation with someone invisible! With both hands on the steering wheel and no wires connected to their ears, there is no trace of connection to their mobile phones at all! Until I got introduced to the wonders of mobile technology and learnt about Bluetooth, I wondered what their secret was. Yes, I admit I was that slow then.

 

Bluetooth
If like me once, you don’t know what Bluetooth is, here’s a quick introduction. It’s low cost, low power, short-range wireless communication system that replaces cables. Increasing numbers of PCs, mobile phones, laptops, digital cameras and game consoles now have Bluetooth, especially since the radio frequency is secure and internationally unlicensed and of course because most people hate having to deal with messy cables that all end up getting knotted up.

 

Bluetooth technology provides the platform for devices to connect to each other and depending on what’s programmed into their Bluetooth profile these devices can do various things over short distances. Bluetooth devices are divided into power dependant classes. Class 1 has a range of 100 meters, Class 2 has 10 meters and Class 3 has a 1 meter radius.

 

Capabilities
Among various things, Bluetooth will allow users to talk on handsfree, print on Bluetooth printers and even send commands to remote control cars. Advances in Bluetooth technology now enables mobile devices with the right Bluetooth profiles to carry out more complex tasks. For example, instead of just carrying a plain voice signal as in Bluetooth handsfree headsets, more advanced headsets can carry high quality stereo sounds more suited for listening to music. That special Bluetooth technology is called A2DP and the object of this article.

 

A2DP
A2DP was created specifically for the transfer and streaming of music and other high quality sounds. It stands for Advanced Audio Distribution Profile, and is designed to transfer a 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio.

 

Mobile phones and PDAs that have A2DP can directly stream music to the A2DP compatible headsets and speakers. Mobile phones that do not have A2DP will still be able to use the Bluetooth handsfree functions. External Bluetooth USBs are also available to enable computers to have A2DP.

 

Of course many earlier Bluetooth mobile phones and portable media players do not natively support A2DP, while some newer Bluetooth 2.0 headphones do support it. A2DP adapters and gateways can be used to overcome this problem.

Devices
Some of the A2DP gateways available in the market include the Motorola DC800 stereo adapter, Nokia AD-42D wireless audio gateway, Siemens Gagaset ZX2, Sony Ericsson BMR-100 and the Sony Ericsson MMV-200 media center.

Music lovers all over the world now look at A2DP as an essential function when shopping for a new phone. Most of the latest mid and high end phones from major brands ususally support A2DP but it’s best to confirm specifically that the model you want to buy has A2DP if you are planning to enjoy high quality music using Bluetooth speakers or headsets.

With the passing of each day, Bluetooth and A2DP are being added to a myriad of devices! The growing demand for A2DP is not surprising since “music is food for the soul” and transcends the murmur of syllables and sounds. So stay in touch, enjoy your music, get your work done and share! All with your hands free.
