What Is Bluetooth?

Bluetooth technology employs a short-range radio wave as a method of exchanging data or sound between devices including cell phones, computers, or other accessories over a short distance without a wire. Bluetooth technology is purposed as a wire substitute that creates a secure connection between devices.

The name “Bluetooth” has its origin in a 10th-century Danish king named Harald,who succeeded in bringing different and fighting local portions together in unity. Like its namesake,  technology brings a wide range of devices across many industries together through a unified communication standard.

Bluetooth Technology

Blutooth was created in 1994 and meant as a wireless substitute to wires. It is based on the same 2.4 GHz frequency as other wireless technologies in the home or office, including WIFI Routers and cordless phones. In addition, it creates a 10-meter (33-foot) radius wireless network call a personal area network (PAN) or piconet that can be network between two and eight devices. With this short-range network, you can, for instance, send a page to your printer in another room without untidy cable sticking on the floor.

In contrast it uses less power and is less costly to do compared to Wi-Fi. This is because of its low outreach. Likewise, you are less likely to suffer from interference from other devices on the 2.4GHz frequency band or cause any to other devices in the vicinity of yours.

Bluetooth Connection

A lot of mobile devices come with built-in radios radio emitting Bluetooth signals. An instance can be, if a device is not having an in-built radio and is a PC or other similar device, the addition of a Bluetooth dongle makes them -enabled.

The process of connecting two devices remains called “pairing”. Devices typically broadcast their presence to each other, and the user selects the  device to connect to when their name or ID appears on their device. Due to the fast growing of -enabled devices, you must learn which devices you could connect with at the right time and which devices they are. Hence, you will be asked to enter a short password that will assist you from connecting the wrong device.

Bluetooth Limits

There are a few downsides to Bluetooth. The first is that it can drain the battery of wireless mobile devices like smartphones. However, as technology (and battery technology) improves, this issue is more minor of a concern than before.

Also, the range is pretty limited, typically only around 30 feet. And as with all wireless technology, obstacles such as walls, floors. Or ceilings can further reduce this range.

The pairing process can also be complex, often depending on the devices involved, manufacturers, and other factors that can cause frustration when trying to connect.

How Secure Is Bluetooth?

It is consider a relatively safe wireless technology when used carefully. Connections are encrypted, preventing eavesdropping on other nearby devices. It devices also frequently change radio frequencies when paired to prevent easy break-ins.

The plans also offer a variety of settings that agree the operator restricts it connections—device-level security to “trust” a device limits. Links to only that specific device. Service-level security settings also agree that you limit the activities your machine can do while connected via Bluetooth.

However, there is always a security risk as with any wireless technology. Hackers have developed a variety of malicious attacks using it networks. For example, “Blue snarfing” refers to a hacker using  to gain authorized access to information on a device; With blue bugging, an attacker takes over your mobile phone with all its functions.

What Is A Bluetooth Speaker?

Bluetooth powers intelligent speakers like Amazon Echo and Google Home devices. And portable wireless speakers designed for indoor, outdoor, and beach use.
