Bluetooth 5 is finally here and Samsung is leading the way by baking it into the Galaxy S8 range. You probably have questions. Luckily, we have answers. Here’s all you need to know.

(Update: March 29 2017): The Samsung Galaxy S8 and its larger S8+ stablemate will be the first phones to hit the market with next-gen Bluetooth 5.0 wireless connectivity.

The new standard, released for use back in December, promises quadrupled range compared to Bluetooth 4.2. That means the Galaxy S8 can be up to 800 feet away from compatible headphones, speakers and fitness trackers while maintaining connectivity.

Bluetooth 5.0 also promises twice the data transfer speed of the previous version.

However, perhaps most excitingly, Bluetooth 5.0 has enough bandwidth to support two sets of wireless devices at the same time.

This could mean speakers in different rooms, or the ability to listen to support two sets of headphones without having to share a bud with your friend (as romantic as that is).

All of this, of course, is dependent on having compatible devices. Unfortunately that means going out and buying all of that tech alongside the S8, in order to reap the benefits. At least Samsung is getting the ball rolling.

The next Bluetooth Standard, Bluetooth 5, brings with it some serious upgrades including increased range, speed, and broadcast messaging capacity.

So what exactly is Bluetooth 5 and why does it matter? Let’s start with the basics.

What’s better about Bluetooth 5? It’s faster, has longer range, and can transfer more information.

Why does that matter? Aside from the obvious benefits, the new standard is going to help support the IoT.

When is it coming out? It’s already here!


Bluetooth is a wireless connection standard intended to connect disparate devices and transfer data over short distances. It is fittingly named after 10th-century king Harald Bluetooth, who united Denmark’s tribes into a single kingdom.

Bluetooth was invented by Ericsson in 1994, but it wasn’t until 1998 that the Bluetooth Special Interest Group (Bluetooth SIG) was established by Ericsson, IBM, Intel, Toshiba and Nokia, and 1999 when it was initially standardised.

The Bluetooth SIG, which has since grown to some 25,000 member companies, has overseen Bluetooth’s development ever since.

The last major version of the standard, Bluetooth 4.0, was officially rolled out in 2011, while the last iterative update was Bluetooth 4.2 on December 2, 2014. Now it’s time for Bluetooth 5 to enter the stage.

You’ve probably noticed that Bluetooth SIG has dropped the .0 from the version number for Bluetooth 5, as well as the ‘v’ (it’s technically Bluetooth v4.2, for example).

This is a pretty straight-forward marketing decision on Bluetooth SIG’s part, aimed at: “Simplifying our marketing, communicating user benefits more effectively and making it easier to signal significant technology updates to the market.”

So what does Bluetooth 5 have to offer? Here’s what we know so far.


Bluetooth 5 offers twice the the data transfer speed of the previous version, Bluetooth 4.2 while increasing the capacity of data broadcasts by 800%. With Bluetooth 5 you can send and receive much more data much more quickly.

The new standard is effective over four times the range of Bluetooth 4.2, which will come in particularly useful for things like portable speakers. You’ll be able to wander further away with your phone without stopping the music, for example.

Mark Powell, executive director of the Bluetooth SIG explains: “Increasing operation range will enable connections to IoT devices that extend far beyond the walls of a typical home.”


Bluetooth 4.2 added some features to make it work better with the so-called Internet of Things, and Bluetooth 5 places such functionality front and centre. Of course, its extra range and capacity will help more smart household devices talk to each other, but the increase to broadcast capacity means the new standard will be able to communicate much more easily with IoT devices.

The Bluetooth SIG says the upgrades to range, speed, and capacity will “redefine the way Bluetooth devices transmit information, moving away from the app-paired-to-device model to a connectionless IoT where there is less need to download an app or connect the app to a device.”

Powell adds: “Bluetooth will be in more than one-third of all installed IoT devices by 2020. The drive and innovation of Bluetooth will ensure our technology continues to be the IoT solution of choice for all developers.”


Bluetooth 5 isn’t just about being faster and longer-range than before – it’ll also help facilitate additional location-based functionality. In particular, it should boost the uptake of Beacon technology, which will result in significantly improved indoors navigation in shopping centres and the like.

This will be possible because Bluetooth 5 will add “significantly more capacity to advertising transmission,” according to Bluetooth SIG. This means that it will be able to convey much more information to other compatible devices without forming an actual connection.

Previous Bluetooth standards already do this in order to notify you about the name and nature of other open Bluetooth networks, but it seems Bluetooth 5 will be able to do much more with it.

As the Bluetooth SIG puts it: “With the major boost in broadcast messaging capacity, the data being transferred will be richer, more intelligent.”

Bluetooth 5 will add location and navigation functionality, so that Beacons can transmit custom information without connection and application barriers.

In other words, you won’t need to install an app or go through connection set-ups in order to receive specific location-based information from Bluetooth Beacons.


While your existing phones, speakers and equipment may work with Bluetooth 5 devices, they almost certainly won’t benefit from its extra capabilities. That means you’ll need to buy all-new Bluetooth 5-ready gear to take advantage of its entire expanded feature set.


Bluetooth 5 went live back in December 2016, and is now already available in devices. Probably the biggest Bluetooth 5 news recently is that the technology features in the Samsung Galaxy S8. Samsung’s new flagship is actually the first handset to scoop the Bluetooth 5 tech.
