Bluetooth Electronic Board Design

BLUETOOTH BASED ELECTRONIC BOARDS

CUSTOM TAILORED PRODUCTS  DESIGN AND MANUFACTURING 

Bluetooth technology allows the exchange of data and information wirelessly. Let's say that these are modules that can communicate with each other, wirelessly, via radio, between maximum distances of 100 meters. Similar devices were used in walkie-talkie transceivers and radio controls. Over the years, thousands of wireless devices have flourished for transmissions used in the medical sector, alarms, data transmission, etc.

We can develop wireless devices based upon your specifications. Typical application ranges from WEARABLE DEVICE to INDUSTRIAL CONTROLLER, HOME APPLIANCES, MEDICAL EQUIPMENT, REMOTE CONTROL and so on.

The use of wireless technology dramatically reduces the cost of the overall system. It will add many important option to your product reducing at the same time sizes and dimensions. Reducing hardware connections benefits the long term reliability of your product. Contact us today at bernini@bernini-design.ro

 THE HISTORY OF BLUETOOTH

Since the 60's electronic enginners were looking for the best wireless solutions. However, a device with standard features was missing, on the platform of which a series of products could be developed with a kind of compatibility, international approvals, low battery power consumption, and most important of all, total immunity from disturbances and interferences.

We can say that there was a huge void to fill. But no one had yet thought about designing and standardizing a wireless device let's say 'universal'. This void has been largely filled by the BLUETOOTH system. We can say that today we have over a billion BLUETOOTH-based radio devices in the world.

BLUETOOTH was born as a short distance radio communication development by Nils Rydbeck. This person, systems developer at ERICSSON, had the vision and concreteness of carrying out the project with a team of very efficient developers. The initial idea was to design wireless headphones, but the team saw an immense opportunity along the way. Let's not go into the details of the official invention and the various inventors involved in the project.

We can say that today technology has defined itself and everything is organized and maintained by the Bluetooth Special Interest Group (SIG). Initially groups such as Nokia, Intel, IBM and Ericsson, and others, have started to adopt the system called BLUETOOH.

In 2001 IBM presented the terminal with integrated BLUETOOTH and ERICSSON presented its own T39 mobile phone equipped with BLUETOOTH. To date, the consortium that joins Bluetooth has hundreds of important companies.

The name adopted for this technology is a little unusual. It refers to a Scandinavian leader king Harald Bluetooth who brought together populations of different languages. BLUETOOTH is in fact a system for communicating between different devices. Not bad the idea of ​​the name introduced by the developer in INTEL Jim Kardach.

Without going into details, let's focus on the key features that have enabled the exponential development of electronic boards based on BLUETOOTH.
