The world of technology has gone wireless with a lot of things. A prime example would be earphones and headsets - gone are the days when they were reliant on wires to keep them functional. Now, these devices come with a Bluetooth option for a wireless option!
Bluetooth is a short-range wireless technology standard that is used for data exchange. This is a standard wire-replacement communication protocol mainly used for low power consumption. Wavelengths are used to transmit information, however, the caveat to this is that it works for short distances.
Bluetooth generally sends and receives radio waves in a band of different channels with about 79 different frequencies on a 2.45 GHz set. Bluetooth devices can detect and connect to other Bluetooth-equipped devices! Bluetooth connections do not interfere with one another because each pair uses different ones in the 79 available channels.
There is a myriad of uses for Bluetooth. This list will summarize the popular and mainstream Bluetooth applications that you can see in day-to-day life!
Yes! Despite the idea that devices are wirelessly connected, these devices are generally safe and secure from hacking. Bluetooth has several security measures that ensure that devices are safe from intruders.
This is done through a process called Pairing. This process will equip both devices with a special security key that allows both devices to connect.
Also, users have ultimate control over a device's visibility to other Bluetooth devices! In any device settings, a user can choose if other devices can see them.
Bluetooth connections are encrypted and security options are pretty much under the user's control. So, there are no worries about any sort of wire-tapping or hacking!
One of Bluetooth's limitations is its range. It's termed short-range technology since it has a communication range of 30 feet (10 metres). However, this can still vary depending on different factors:
The medium through which the signal travels such as wood, concrete, metal, and even distance and humidity can weaken a Bluetooth signal or connection.
Along with the rest of the technology, there is a promising future for Bluetooth. The current version of Bluetooth is the Bluetooth 5.2 and engineering teams believe that it's just going to get more reliable and faster from here.
