What Is Bluetooth?

Bluetooth is a short-range wireless message technology that enables devices such as cell phones, computers, and peripherals to transmit data or voice over a short distance wirelessly. The purpose of Bluetooth remains to replace the cables that typically connect devices and keep communications between them secure.

The name “Bluetooth” comes from a 10th-century Danish king named Harald ,who united disparate and warring regional factions. Like its namesake,  technology brings a wide range of devices across many industries together through a unified communication standard.

Bluetooth Technology

Bluetooth was develop in 1994 and was design as a wireless replacement for cables. It uses the same 2.4 GHz frequency as other wireless technologies in the home or office, such as B. cordless phones and wireless routers. 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. This short-range network allows you, for example, to send a page to your printer in another room without running an unsightly cable.

Bluetooth uses less power and is less expensive to implement than Wi-Fi. Due to its low power. It is also much less likely to experience or cause interference from other wireless devices on the same 2.4GHz frequency band.

Bluetooth Connection

Many mobile devices have built-in Bluetooth radios. For example, PCs and other devices that do not have a built-in radio can be made -enabled by adding a Bluetooth dongle.

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. With the proliferation of -enabled devices, it becomes essential for you to know when and what device you are connecting to. Therefore, you may need to enter a passcode to ensure you’re connecting to the correct 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.
