What is Bluetooth 5.0?

Bluetooth 5.0 emergence was announced on 16 June 2016 to come on board in the last quarters of 2016 or early 2017. Finally this is 2020 and 5.0 versions is here with us.

The developers of this version of Bluetooth made it to meet all the advanced standard of wireless world with more privacy and security.

In fact, Bluetooth 5.0 has its parking slot in the tech world especially with the arrival of 5G networks technology. It joined in setting the stage for the future world of smartphones, smart homes, and smart industries. Bluetooth is revolutionizing how people experience the Internet of Things. Its specification includes the low power consumption, inexpensive hardware and, small size implementations.

It is the continuation of Low Energy LE. Its speed is 48MBps (double of the 4.2 version). It can be connected up to the distance of 300 meters or 985 feet (4 times last version). The ISM band ranges from 2.4-2.485 GHz.

One other good thing for users is that it has backward compatibility with its old or previous versions.

In other words, if you bought one of these recent smartphones with Bluetooth 5.0 technology, you can still be able to connect with your old accessories like headphones even if they are made of Bluetooth 2.0 technology but the difference will always be clear when the Bluetooth in your smartphone sees its kind in a peripheral gadget.

Features of Bluetooth 5.0

Power requirement

The Bluetooth 5.0 has been formulated to use less power on your device compared to the predecessor versions.

That means you can keep your Bluetooth switched on for a longer period of time without it affecting the percentage of your battery capacity. This is unlike the previous version which have direct effects of consuming more power.

Message Capacity

Bluetooth 5.0 is built in such a way that it has large Massage capacity of about 255 bytes which gives more bytes-capacity for actual data payload unlike it immediate predecessor, the Bluetooth 4 which has small message capacity of about 31 bytes which only gives just 17 to 20 bytes for actual data payload.

Bluetooth beacon

The Bluetooth 5.0 beacon has become more popular due to the increase in range and speed unlike the older versions with less speed and range as well as low Message capacity.


Bluetooth 5.0 is very fast; this made it able to meet the requirements of internet of things. The bandwidth of 5Mbps is also a plus in the advancement of internet of things through Bluetooth 5.0.

Support for Internet of Things (IoT) devices

Bluetooth 5 easily meets the requirements for IoT devices with its good range and increase in speed unlike other previous version with low bandwidth and speed. Internets of things are now supported fully in smart homes, smartphones and even in smart industries.


Though all the features of Bluetooth 5.0 may not be utilized by lower versions of Bluetooth, It is backward compatible. Irrespective of version, you can strongly connect with this latest version of Bluetooth.

Benefits of Bluetooth 5.0

The Bluetooth 5.0 takes up low energy

Due to the very significant issue of battery consumption by the older versions of Bluetooth, there is now a new turn around making this latest versions to be power effective whether paired with peripheral accessories or not.

With Bluetooth 5.0, all audio devices communicate over Bluetooth Low Energy, which means reduced power usage and longer battery life. Many more types of devices will be able to communicate over Bluetooth Low Energy in the future.

Notably, Apple’s AirPods don’t use Bluetooth 5.0. They still use Bluetooth 4.2 through the help of the special Apple W1 chip for an improved connection. On Android, Bluetooth 5.0 helps to make headphones impressive.

Dual Audio

Bluetooth 5.0 also enables a cool new feature that allows you to play audio on two connected devices at the same time.

In other words, you could have two pairs of wireless headphones connected to your phone, and then stream the same or different songs to both of them at once, all via the standard Bluetooth.

Or you could play audio on two different speakers in different rooms. You could even stream two different audio sources to two different audio devices at the same time, so two people could be listening to two different pieces of music, but streaming from the same phone.

This effect is known as ‘Dual audio effect’. It is active on the Samsung Galaxy S8 and its other latest versions.

Just connect two Bluetooth audio devices to your phone, turn on the Dual Audio feature, and you’re ready to go. However, this shouldn’t be a Samsung-only feature. It’s enabled by Bluetooth 5.0 and will hopefully appear on other manufacturers’ devices, too.

More Speed, Distance, and Throughput

Bluetooth 5.0’s primary benefits are improved speed and greater range. In other words, it’s faster and its connectivity can remain strong over greater distances than older versions of Bluetooth.

The official Bluetooth marketing material from the Bluetooth standard organization advertises that Bluetooth 5.0 has four times the range, two times the speed, and eight times the broadcasting message capacity of older versions of Bluetooth. Again, these improvements apply to Bluetooth Low Energy, ensuring devices can take advantage of them while saving power.

With Bluetooth 5.0, devices can use data transfer speeds of up to 2 Mbps, which is double what Bluetooth 4.2 supports. Devices can also communicate over distances of up to 800 feet (or 240 meters), which is four times the 200 feet (or 60 meters) allowed by Bluetooth 4.2. However, walls and other obstacles will weaken the signal, as they do with Wi-Fi.

Technically, devices can actually choose between more speed or a longer range as  twice the speed benefit is also possible  with short range between devices sending data back and forth. The increased range would be optimal for Bluetooth beacons and other devices that only need to send a small amount of data or can send the data slowly, but want to communicate at greater distances. Whichever one you prefer; the long or short range, you can be sure of low energy consumption.

Devices that support the latest Bluetooth 5.0

Bluetooth review

You can get devices that support Bluetooth 5.0 today, they are many of the devices ranging from smartphones, headsets and other accessories. For example latest iPhones, Samsung Galaxy Series, AirPhones Bluetooth headphones and other latest devices have this latest Bluetooth version.

 You’ll also need Bluetooth 5.0 peripherals to enjoy the full benefits this latest Bluetooth has to offer, however.

Because Bluetooth is backwards compatible, all your Bluetooth 5.0 and older Bluetooth devices will work together. It’s a bit like upgrading to a new, faster Wi-Fi standard.

Even after you get a new router that supports faster Wi-Fi, you have to upgrade all your other devices, too. But your older Wi-Fi-enabled devices can still connect to your new router, but at a slower speed than the router supports.

If you can get your hands on an Android phone with Bluetooth 5.0 and Bluetooth 5.0 headphones, you’ll likely have a much better wireless audio experience than you would with the older Bluetooth standard.

iPhone users can get a good experience with Apple’s own AirPods or Beats headphones thank

s to the W1 chip, but solid Bluetooth audio is easier to get on Android now, too.

Bluetooth 5.0 should even improve wireless headphones on the iPhone if you choose to go for third-party Bluetooth 5.0 headphones instead of Apple headphones with a W1 chip.

I am advising you to upgrade all your gadgets to Bluetooth 5.0 because even if you have a Bluetooth 5.0-enabled laptop, for example, upgrading to a Bluetooth 5.0-enabled mouse probably won’t be a big improvement.

But, as support for Bluetooth 5.0 finds its way into every new Bluetooth device, Bluetooth peripherals will get better and Bluetooth will become more reliable and power-efficient.

The Bluetooth 5.1 and 5.2 versions

While we are still rejoicing over the emergence of Bluetooth 5.0, other higher versions entered with its entourage of improvements. These higher versions include Bluetooth 5.1 and 5.2 versions.

Many specs differentiates these two versions from their predecessors. Let’s start with Bluetooth 5.1.

Bluetooth 5.1 came with the following tech improvements:

  • Direction finding: with this, Bluetooth 5.1 is made in such a way as to use Angle of Arrival and Angle of Departure through the receiving device. With these two angular methods, the direction and location of the sending device can be processed.
  • Also in the make of the entourage is the generic attribute profile which helps a device to be strongly connected with another and to also allow clients without a trusted relationship with a server to retain their attribute cache.
  • It came in such a way that its scalability, Reliability, and Energy efficiency are duly enhanced.

These three major things mark the entrance of Bluetooth 5.1 and a true game change.

As if we have seen it all, Bluetooth 5.2 made a triumphant entry.

Today we have Bluetooth 5.2, though on the background. This very version of Bluetooth has promised to be packed with great spec that are capable of making great turn around in the speed of Bluetooth and the latency period. Below are the cardinal component of Bluetooth 5.2:

  • Isochronous Channels (ISOC): here Bluetooth 5.2 does not only send data to only one or two but sends it to many ready devices. This is done through connection-oriented and connectionless communication.
  • LE power control which helps one Bluetooth, the receiver to assess the signal strength range of the sender-Bluetooth. With these effect, better control over the quality of the signal is assured.
  • Bluetooth 5.2 also came with improved GATT profile called Enhanced Attribute Protocol. This is special as it helps to boost interactions between Bluetooth app and other app enabling them to resist interferences by the processes of other apps.


In this review, I have been able to lay bare most things concerning Bluetooth 5.0 version, compared it with Bluetooth 4.2 version. I have also highlighted the most essentially features of Bluetooth 5.1 and Bluetooth 5.2 which are the latest version of Bluetooth versions.

Bluetooth is one of the file transferring protocol that haven seen drastic changes and yet, is still not tired of improvement because as human hunger for higher tech wax strong, changes in technology will remain constant.

Remember that it is only few smartphones, if at all, which currently use any of these latest versions of Bluetooth 5.1 and 5.2. Thanks for reading and do check our review page for more interesting reviews.
