Bluetooth signals – how does it work and what can it be used for

Have you ever woder what bluetooth is or what is called bluetooth? Well this article will be all about it bt you will also be able to find out how does bluetooth work.

There are many devices that includes bluetooth technology. Nowadays those devices are for example mobile phones, smartwatches, fitness trackers or other devices. If you want to know more about bluetooth keep reading the article!

Bluetooth technology

Bluetooth is best known as transmitting audio just like for example in Bluetooth headsets however there is more to find out about it, keep on reading and find out.

Bluetooth technology can indeed be found in many devices nowadays. This technology helps people to stay in touch with our loved ones. This wireless technology is very helpful when we want to connect two bluetooth devices with each other, for example Bluetooth can help you connect your phone to your car and allow you to listen latest podcasts during our morning commutes. Bluetooth technology can even learn which radio channels are working good.

How does bluetooth technology works?

The most important factor to make it all work is this that bluetooth devices have to always be paired. What does it mean? Well it means that those two devices trusts each other and is able to exchange the date in safe way bby using encryption.

Bluetooth connection can be considered as some kind of electronic conversation between devices that have some data to share.

Types of bluetooth technology

There are in fact two types of bluetooth technology. Those types are:

• bluetooth low energy (LE),
• Bluetooth Classic (BR/EDR).

Both types are using the same kind of frequency band, however low energy is way more popular. Why? Because it takes less energy to operate and can be used for mesh networks and broadcast.

Factors that are affecting the range of Bluetooth devices

That is right there are several factors that might affect the range of bluetooth devices. If you want to find out what are those factors here they goes:

• radio spectrum – when it comes to radio spectrum this is very good choice when it comes to bluetooth enabled devices,
• antenna gain – this is in fact changing electrical signal strength that comes from the transmitter into radio waves and then comes back again on the receiving end,
• transmission power – the higher the transmitted signal strenght is the longer the range can be achived. Remember that increasing this power will affect the battery life,
• path loss – there are also factors that can weaken the signal. Those factors are for example distance or the humidity,
• physical layer – this factor is defining some crucial aspects on this how the radio is used to transmit but also receive data rate, how error detection is being formed, interference protection and many other techniques that influence signal clarity over different ranges,
• receiver sensitivity – this is quite simple to understand because it measures the minimum signal strength at which someone can receive correctly decode data.

How to fix connection problems?

If you are wondering how to fix connection problems here goes some ways to fix it:

• do not place bluetooth device near metal objects, brick walls, marble and also bulletproof glass,
• restart your router,
• keep your bluetooth device near the router,
• do not place it next to the microwave ovens and fluorescent lighting.

Wireless devices – what kind of bluetooth device you own?

Not all of devices has got this amazing wireless technologies inside them however there are many bluetooth versions which are wire devices versions. Here goes some of the wireless devices:

• baby monitors,
• cordless phones,
• keyboards,
• wireless headphones,
• toys,
• medical devices,
• automobiles,
• audio speakers,
• toothbrush,
• smart meters,
• smoke detectors,
• satellite dishes.

As you can see bluetooth devices are all around you, and you probably use it everyday and they are other bluetooth devices rather your mobile phone only.

Wireless networks

Wireless network can be used to transport the data from WAP client to a WAP server. What is cool about it, is this that The WAP client can make use of Bluetooth’s SOP to find the WAP server. This in fact is very useful when the WAP device is a phone.

Facts

• if you are wondering who is regulating Bluetooth technology it is the bluetooth special interest group,
• electronic devices that are in home can be connected to central control system via Bluetooth,
• material objects might be blocking bluetooth since the Bluetooth waves move through the air,
• it is important to know that connected devices via bluetooth are in fact considered as a part of personal area network,
• wireless fingerprint exists not only in WI-FI but also in other wireless technologies,
• forward error correction is a new technique which improves receiver sensitivity,
• there is a process called pairing which equips each device with special security keys and causes them to trust each other, this is so called bluetooth security,
• if you are wondering what can interfere with bluetooth the answer is easy because any kind of device that is using 2.4GHz radio frequency can do that.

Conclusion

As you could notice reading the article there are multiple devices which are not only mobile devices that are supported by bluetooth signal. Go for it and use amazing wireless communication on your own.

If you are wondering where can you buy certain devices you will for sure be able to find it in your local electronics store however if you won’t be able to find there the one device you are dreaming of yoou can always order it online.
