Bluetooth exists in many versions, but how they differ from each other, and what can the different editions? We will guide you through Bluetooth the universe.
Everyone knows about it and everyone uses it. The wireless technology Bluetooth is to be found on virtually all technological devices today and will be used for everything from music playback for data transfer, calls in the car, Manager of the home, and much more.
More recently, there is also an increased focus on the use of Bluetooth, since mobiles as Moto Z and of course iPhone 7 has dropped the classic 3.5 mm jack and instead has wagered on the wireless connection, named after our Danish King.
Bluetooth technology is, of course, just like any other modern technology has improved a lot over the years, and most recently, we have reached version 4.2 on the latest smartphones, tablets, computers, etc.
But wherein lies the difference, and is it bad off with Bluetooth 4.0 rather than the latest version? Read the following and see the differences on the latest versions of the wireless technology.
The third version of Bluetooth is also called Bluetooth High Speed, and as the name suggests, it is significantly faster than its predecessor Bluetooth 2.0.
Most wireless earphones, inter alia. Sony XB950BT and Plantronics BackBeat FIT, running also with this version, which allows a fast-speed of data transfer at 20 megabits per second.
With version 3.0, there is additionally added an enhanced power management, which makes it possible to maintain a quality connection to your headphones at a minimal power consumption, as well as increases the strength, if you were to move you further away from your wireless device.
With Bluetooth 4.0 was an improved connectivity and a larger range was introduced, but it is especially the nickname Bluetooth Low Energy, there are interesting in this fourth version.
Low Energy is especially intended for the so-called “Internet of Things, which in all its simplicity is that all everyday objects will be connected technologically.
Bluetooth 4.1 continues in Low Energy category and lets your wireless devices being connected even longer, without emptying your battery completely.
Low Energy is therefore even better integrated into 4.1, with an intelligent management of flow makes sure to adjust, depending on distance, when to use more energy.
In addition, with Bluetooth 4.1 been corrected problems with that Bluetooth was interfered with by other wireless technologies, b.a. 4 g connection.
The head of us looked forward to the latest technology, Bluetooth 4.2, as we look at all the new smart devices today, as well as on several of the latest wireless headsets, and more.
With 4.2 speed for data transfer again get a boost, and this latest version was said to be up to 1.6 times faster than in the past.
In addition, there are with 4.2 comet enhanced security compared to Bluetooth Beacons, which are senders of Bluetooth signals, you can read on your device.
With the increased security, these Beacons will no longer directly track you and your data unless you give permission to do so.
On all the new models like the iPhone 7, Samsung Galaxy S7 and Note7, OnePlus 3 etc. It is precisely the Bluetooth 4.2, which is to be found on the specification list.
What about Bluetooth 5.0?
Bluetooth 5.0 was presented a few months ago and will once again add improved speed and range, as well as be even better to support the aforementioned Internet of Things in Low Energy Bluetooth.
Specifically, the scope will be enhanced to up to 200 metres outdoor, and 40 metres indoors, given that it is not the direct objects in the path of the connection. Thus, there is URf.eks. better opportunity to all smart devices in your home can talk together on the same connection.
But it is in the improvement of the Beacon system, that Bluetooth 5.0 gets really interesting. With previous versions you could only add 31 bytes for a Bluetooth Beacon, URf.eks. via Apple’s iBeacon or Google’s Eddystone, and thus it was very limited in what you could add information to a Beacon.
With Bluetooth, however, this figure will be 5.0 screwed up to 255 bytes and allows for the stores, businesses or others can add even more advanced information for these Beacons.
There goes probably some time before we get Bluetooth 5.0 to see on some kinds of electronic appliances, and a good bet might be the end of 2017.
