In short, in previous versions of bluetooth, a device would have to go through a specific set of channels to discover and connect to the item it was pairing too. The improvement in this area is mostly due to something called randomized channel indexing. This can be a lot more precise now.īluetooth 5.1 also introduced slight improvements in the caching and pairing processes that make advertising and discovery much more efficient.Īdvertising here is the term used for the process devices use to announce they are ready to pair. Previously, the technology would have to essentially guess the distance between devices. These different methods are Angle of Arrival and Angle of Departure, which essentially allows your receiver and transmitter to know exactly where they are positionally situated in relation to one another. One of the biggest changes that resulted from the upgrade to 5.1 is the use of different direction finding methods. There are small incremental improvements that are made, but that doesn’t mean that they are on the whole insignificant. It’s important to start with some of these key points because - as you can maybe tell by the name - there isn’t a ton of difference between Bluetooth 5.0, 5.1 and 5.2. Now this is not just a Samsung specific feature, but it is an example of the overall greater data capabilities of Bluetooth 5.0. So, you could have one phone streaming music to two different connected headphones, or perhaps to two different bluetooth speakers. This essentially allows you to play audio on two connected devices at the same time. The Galaxy S8 was the first smartphone to employ Bluetooth 5.0, and introduced (and also named) this feature. This opens up a world of possibilities, perhaps one of the most noteworthy examples of this to mention being Samsung’s Dual Audio. This previous range was about 50 feet, and theoretically farther if there were absolutely no obstructions in the way, but that doesn’t generally happen all that often when you are using bluetooth in a home or work setting.īluetooth 5.0 upped this to about 120 feet, meaning you could be outside, in different rooms, on the beach with lots of things in the way and your signal would be able to remain pretty strong without cutting out, which is a huge bonus that ups the usefulness of your wireless tech exponentially.įinally, Bluetooth 5.0 probably warranted the jump to an all new number name because it introduced 8 times the data capability of the previous versions. If interested check out our article, Bluetooth 4.2 vs Bluetooth 5 sound quality.īluetooth 5.0 was capable of data transfer at double the previous speed - which is obviously immensely helpful for pairing, as well as eliminating any annoying latency issues, especially with regard to streaming videos, movies and tv over the internet.īluetooth 5 also greatly expanded the range over which signals could be transmitted between devices. You can tell since the last version before this was Bluetooth 4.2 - that’s obviously a fairly significant jump. It wasn’t until Bluetooth 5.0 was introduced in 2016 that the first real significant modern changes were made. While Bluetooth has had many different updates over time, most of these have been fairly mundane changes that come with technology maturing - faster speeds, better processing capabilities, more data etc. This article will explain why the last few versions have been the greatest leap the technology has taken in its long run, and specifically what the newest versions are bringing to the table that could revolutionize Bluetooth audio for the future. With so many updates over the year, it can be confusing to know how each of these is different from its predecessor, and how much of a difference it makes when you’re trying to assemble gear. Bluetooth has had a lot of different versions since its inception in 1998.
