Hi, I am new here! As my first post, I would like to talk about something that I love, which is wireless technologies. Because this term is so huge and there are a lot of different types for different kind of situations, let's get focused on a emergent one called Bluetooth.

Bluetooth is a low power, low cost and short-range technology that is inteded to replace the cables connecting fixed devices and portables. One of the big advantages of Bluetooth, in my opinion, is that it has a Special Interest Group (SIG) that drives the development of the technology and brings it to the market. Until here, nothing new, it looks like another group, but let me explain... the SIG is composed of more than 8,000 member companies that works in different areas, such as telecommunications, computing, automotive, music, apparel, industrial automation and network industries! As you can see, there are a lot of people interested in making Bluetooth grows!

I think that the first time I saw Bluetooth was in a mobile store, I have asked the salesman about something that later got known as mobile phone headset. Have you ever tried to get your hands free (have fun with this youtube advertisement video)? But, after that, a lot of things were invented (and still being!) using Bluetooth, mixing not only new products, but also services. Very briefly, let me just say what has appeared in the media and is in my mind now: cars that you can talk on the phone while is driving, a jacket that allows you to change a music while you are climbing a mountain, sunglasses with hands free for mobiles, watches that synchronizes with the cellphone, a pen that you can write in a whiteboard while it is being transfered to your pc (looks really cool for brainstorming meetings, forget about taking a shot of the whiteboard with your cam!), a bus/train system that tells you when you have arrived in your destination, companies doing Bluetooth marketing (also called as mobile marketing over Bluetooth, we will come back about it in another post), public services available for everyone with a Bluetooth enabled (city maps, museum guides and son on), multiplayer games and some weeks ago, was officially released the first television with Bluetooth! Wow!

There is one more thing I can not forget, in the end of the last year, the Bluetooth SIG has announced that was sold more than one billion of Bluetooth enabled device, most of then mobiles. Can you imagine this number? It is bigger than the number of computers in the world!

With all these facts, that is the part that Java appears! We got a JSR for Bluetooth! It is the JSR 82, which is also called JABWT, Java Apis for Bluetooth. We can talk a little bit more about it in another post! Hope you liked it! ;)

See you,

Bruno Ghisi
