Over the creation of a single standard for wireless data transfer, a number of manufacturers Ericsson, Nokia, Intel, Toshiba and a dozen others, immediately began to think. Having united efforts and having collected all the engineering potential into a single group. The purpose of this group with common interests was to introduce the technology of wireless data transmission. And most importantly the new technology was to become unified, putting an end to the confusion and compatibility of devices when wireless connectivity is required. Later Dell, Xircom, Motorola, Compaq, and Qualcomm all these brands very soon become part of this group. And today SIG consists of more than 30 000 companies from all over the world. Bluetooth has long been perceived as a given and the number of devices in which this wireless communication protocol is integrated cannot be counted.

How the idea of technical advantage began?

The first born of the wireless protocol was announced in 1998, Bluetooth 1.0. Without faults and mistakes, the first version could not be dispensed with. Among the key problems were a very unstable signal and a permanent interruption of the connection. Moreover, manufacturers began to note the lack of proper compatibility of devices. For example, two different companies that released two compatible devices on the market could not be sure that the user would be able to connect them via Bluetooth. The situation immediately rushed to save and a year later introduced an updated Bluetooth 1.0B. It became better but the ideal was still far away. Bluetooth 1.0 (B) required the mandatory transfer of the address of the device, so there was no point in talking /about any anonymity.

Bluetooth technology and update regulation

The first global update was Bluetooth 1.2, which immediately got a number of improvements, from increasing the data transfer rate and improving the noise immunity to support the A2DP profile, which for the first time allowed transmitting stereo sound. In 2004, the manufacturers waited for Bluetooth 2.0. Among the innovations of this version they increased data transfer speed. According to the documentation, Bluetooth 2.0 had a bandwidth of 3 MB/s but practice is a ruthless thing. The maximum that could be squeezed out of Bluetooth 2.0 is 2.1 MB/s.

Conclusion: Bluetooth dongle

The main accent of the technology is extremely low power consumption. Developers have relied on the integration of Bluetooth 4.0 in miniature gadgets, sensors and other devices in which it is impossible to place a large battery. Bluetooth dongle is one of them. The use of this device is so vast that it can be used in car, indoor and outdoor. You can say that bluetooth dongles are useful and the use of this device is done world-wide. It can be used in music systems, call system, mobile technology and internet using.
