Introduction

 

There will be nearly 50 billion
active smart devices in the world by 2020. Bluetooth is a very popular way of
wireless communication. It was created in 1990. There are many wireless technologies
such as ZigBee, WI-FI, Infrared, NFC etc. Developers have been working with
Bluetooth technology for many years. Bluetooth 4.0 works with wireless less
energy intensive without draining the batteries on the devices. Bluetooth 5 has
extra features that may help developers to be furthermore innovative and more
creative in wireless technology. Also, this technology is seeking to be the
primary connector to IoT devices and it will change the way of communication
between IoT devices which can be used within particularly beacons. Then those
connections can be taken into workplaces, large buildings and public spaces,
with more data and information transmitted between the connected devices which
can be used to indoor localization, finding information etc.  Bluetooth 5 enables to build IoT based
solutions with more speed, security and range. These features increase the
reliability of communication between devices.

 

Features of Bluetooth 5

 

1.    
Long Range.

The range of the Bluetooth 5 is two
times larger at the speed of 500 kbps. It is four times faster than previous
technology ‘s speed of 128 kbps.  

 

2.    
Low energy speed.

The speed of Bluetooth 5 technology
is doubling from 1MBps to 2MBps without increasing power consumption.

 

3.    
Greater capacity.

Broadcasting message capacity is
going up by 8 times than the earlier version of Bluetooth. Therefore, more and
more data can be sent and received.

 

4.    
Secure Connectivity.

Bluetooth 5 enables to communicate
between devices more securely. 

 

 

5.    
Interoperability.

Currently Bluetooth is already
enabled in more than 95% of tablets and smartphones. That kind of popularity,
interoperability with other devices is a growing priority.

 

6.    
Simple and fast to pairing.

We can pair devices using Bluetooth
5, more easily and faster than Bluetooth 4.0.
