Bluetooth 5.0 vs 4.0
Bluetooth 5.0 vs 4.0 - Table of contents:
Bluetooth 5.0 is a wireless technology that uses a radio frequency to share data over a short distance, eliminating the need for wires.
You can use Bluetooth on your mobile device to share documents or to connect with other Bluetooth-enabled devices.
For security reasons, Bluetooth devices must be paired before they can begin transferring information. The process of pairing your devices will vary depending on the device you are connecting to.
Bluetooth 5.0 – how it all began
Bluetooth was invented by an electrical engineer Jaap Haartsen in 1994, while working for Ericsson in Sweden, as an alternative to the RS-232 cable standard for connecting PCs to computer peripherals.
Four years later, Haartsen played a crucial role in setting up the Bluetooth Special Interest Group (SIG), comprising 35,000+ member companies in various sectors such as computing, telecommunications, and consumer electronics.
Today, the body controls technology development, protects trademarks, and runs a management qualification program to ensure all manufacturers comply with their standards to sell a Bluetooth device.
So far, Bluetooth has released 12 versions, most of which are stemming from the same series:
What Devices are Compatible?
Now that Bluetooth 5.0 has been out for a few years, most devices are able to support it, such as mobile phone, laptops, wall mounted android tablet.
As a rule of thumb, when a new update is released, typically, only flagship smartphones are fully compatible with the newest features until other tech companies are able to follow suit.
The good news is that Bluetooth 5 is backward compatible with Bluetooth 4, 4.1, and 4.2. This means that if you get the newest android tablet and connect it to a Bluetooth 4.2 speaker, it will still function properly.
Keep in mind that you will only experience the older version’s benefits, so you won’t get the increased range and speed associated with Bluetooth 5.
Here are 7 comparisons to help you decide what works best for your device.
Bluetooth 5 is faster than Bluetooth 4 with the former having 2Mbps, twice the speed of the Bluetooth 4 of about 1Mbps making Bluetooth 5 able to meet one of the IoT requirements. This is thanks to the 5Mbps bandwidth of Bluetooth 5 in comparison to the 2.1Mbps of Bluetooth 4.
Bluetooth 4 supports 50m in the outdoor range and 10m in the indoor range making it so low whilst Bluetooth 5 supports 200m in the Line Of Sight path in the outdoor environment and 40m in the indoor environment. Therefore if you want to listen to your music with your wireless headsets while moving around the house or the courtyard, then Bluetooth 5 will work best.
Bluetooth 5 has been formulated to use less power on your device compared to Bluetooth 4. That means you can keep your Bluetooth switched on for a longer period of time and do much more compared to Bluetooth 4 which consumes more power than its newer counterpart.
The Bluetooth 4 has a small message capacity of about 31bytes which gives just 17 to 20 bytes for actual data payload while the Bluetooth 5 with a large capacity of 255bytes gives more bytes for actual data payload.
With Bluetooth 5, beacons have become more popular due to the speed and range increase while with Bluetooth 4, they are less popular due to the less speed and range as well as low message capacity of 31bytes.
Support for IoT devices
Bluetooth 5 easily meets the requirements for IoT devices with its good range and increase in speed while Bluetooth 4 does not due to its low speed and short working range. That means IoT devices will work well with Bluetooth 5 and utilize all its features properly.
Bluetooth 4 works best with devices that are compatible with version 4 series but will not work with devices that have Bluetooth 5 while Bluetooth 5 is backward compatible with v1, v2, v3, v4, v4.1, and version 4.2 but will not utilize all the features of Bluetooth 5.
