So everyone has probably heard of Bluetooth and you may even know if your phone has Bluetooth 4.1 or 4.2 but generally those different iterations of Bluetooth are just slight improvements to things like pairing time and low energy. It doesn’t really change the way you use it you just know your phone has Bluetooth. But 5.0, that’s a pretty big new number that seems to signify a bigger change. So there are a couple of things you should know about. What is new with Bluetooth 5.0?
There are 3 main things that all enable pretty good new features a
Bluetooth 5.0 is 2x (2 times) faster.
Bluetooth pairing is generally not that quick of a process, you have to do it very often but it’s pretty slow. Bluetooth 5.0 shows a direct advantage of data transferring twice as fast which is the pairing process is with quicker and is also less delay. Bluetooth 4.2 had a bandwidth of 1mb, with Bluetooth 5.0 having twice the bandwidth, it will be 2mb. Ever watch a video on Bluetooth speaker or Bluetooth headphones and the audio is a little bit behind the video, someone talking and you hearing it a split second behind. Usually not too bad but that actually does get solved a bit with Bluetooth 5.0. That delay is a lot smaller.
4x (4 times) the range.
The range has actually been a real weakness of Bluetooth, especially in the past. It depends on what pair of headphones you use, but sometimes you can be listening to music in your headphones and you leave your phone in another room, you walk a little bit too far away and starts cutting out and then eventually stops. That happens all the time. The theoretical maximum range of Bluetooth 4 was about 50 meters with a direct line of sight but about 10 meters in everyday use through walls and around corners. To get very far away from your phone, if you try to listen to music or if you walk around a corner is going to cut out. Theoretical, Bluetooth 5 has a maximum range of 200 m with a direct line of sight or about 40 m around the house or indoors. That’s 120 feet, a serious improvement. So that’s not just like downstairs, but around the corner.
8x (8 times) the data throughput over Bluetooth 4.
The key to understanding broadcast message capacity is understanding Bluetooth beacons first. At its core, Bluetooth beacons are Bluetooth-powered devices that continuously broadcast a signal and other “regular” Bluetooth receivers (your phone, for instance) can perform context-aware actions upon receiving it. If you still feel out of the loop, no worries: Just head up to our Bluetooth beacons explainer.
Bluetooth beacons are hardware transmitters – a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets, and other devices to perform actions when in close proximity to a beacon.
One of the things about Bluetooth 5.0 that hasn’t been noticed is the forward error correction (FEC). With this, sending files that seem through a corrupted signal will be able to repair signal and continue the transmission without having the other device send a signal back requesting for the file to be sent again.
