The bluetooth transmission protocol has been improving enormously in recent years, from reducing consumption to practically a minimum to allowing any type of file to be sent at heart-stopping speeds compared to the first models that began to popularize this wireless communication technology. Just over a week ago, SIG (Bluetooth Special Interest Group) plocated the specifications of what will be the fifth generation of Bluetooth. The main novelties of bluetooth 5 are found in the expansion of the transmission speed and the extension of its range, one of the main limitations of this technology.
At the moment we still have to wait to see the first devices compatible with the fifth generation of bluetooth, but everything seems to indicate that one of the first smartphones to implement this new generation of bluetooth will be the Galaxy S8, although it may be a bit of a fair time if the intention of the company is to present the device at the end of FebruaryUnless the latest notifications related to this device are confirmed, news that states that the launch of this device may be delayed for a few months. If this is the case, it is more likely that Samsung can implement this new generation of bluetooth in its new terminal.
Currently, the latest version of bluetooth is 4.2, a version that offers us a very tight battery consumption, so the new versions in addition to trying to improve consumption (currently secondary) have focused on improving the transmission speed when same as the scope of it, limited to 10 meters without obstacles as you seem in the middle. The terminal that probably and almost certainly if it implements bluetooth 5 it will be the HTC 11, the new terminal of the Taiwanese firm, since its presentation date is scheduled for the month of May.
