Bluetooth is a wireless technology that lets devices connect to each other. It was first developed by Ericsson Mobile to connect a mobile phone to a laptop. IBM and Ericsson then agreed to make the technology an industry standard, allowing anyone to use it. Other companies such as Toshiba and Intel soon followed, and the Bluetooth Special Interest Group was form. In 1998, the first products utilizing Bluetooth were release. Currently, there are thousands of devices using the technology.
The Bluetooth Core Specification, released in 2005, introduced Enhanced Data Rate (EDR) as a way to increase data transfer rates. This technology uses GFSK and phase-shift keying modulation for its transmissions. This new technology can handle much higher data transfer rates, but has lower power consumption. While it is still relatively new, EDR has the potential to make the Bluetooth standard a better choice for a variety of consumer electronics.
The key feature of Bluetooth is its ability to connect to various devices in an easy way.
The most obvious advantage of using Bluetooth is the ease of pairing with other devices. A miscreant can exploit the simplicity of pairing to send unsolicited messages or abuse the Bluetooth service. Malicious code may also compromise your data and access it. Once you download malware, you have to keep an eye on your data. This is why it is important to protect your data and prevent it from falling into the wrong hands.
The Bluetooth protocol works with a star topology. This is a wireless communication system that is manage by one or more synchronize devices. Each device forms a picot of synchronized devices. The picot may contain one master and as many as seven active slaves. Additional slaves are not participating in the network.

During a connection, data can be transmit to the target device. However, in a wireless connection, Bluetooth is vulnerable to malicious code.
A smartphone’s Bluetooth device is a wireless communication device that connects to other devices using the same standard. A smartphone and tablet both need to be Bluetooth-enabled to communicate. A phone or tablet must also have Bluetooth capability to be able to communicate with other devices. Generally, smartphones and tablets have built-in bluetooth capabilities. This enables them to connect to each other and share files. Smart phones can also connect to other Bluetooth devices.
The Bluetooth protocol uses two components.
The radio device generates a Bluetooth signal. The digital controller runs the Link Controller and interfaces with the host device. The Link Controller processes the baseband and manages the ARQ and physical layer FEC protocols. The latter is the main component of a Bluetooth network. A smartphone or tablet that is paired with another device is known as a “link”. The two devices can communicate with each other through a wireless network.
The Blue-tooth Core Specification was first released before 2005. This version introduced EDR, which provides faster data transfer rates. Its bit rate is 3Mbit/s and the maximum data transfer rate is 2.1Mbits. The EDR uses GFSK and phase-shift keying modulation. It is not limited to phones. Several different devices can connect to one another wirelessly. It is also compatible with a range of devices.
The Blue-tooth SIG is composed of members with different expertise and different needs.
The members of the SIG are responsible for deciding which specifications are compatible. This protocol is a vital part of the Bluetooth technology. It is essential for a phone to communicate with other devices. This is where it really shines! The SIG helps manufacturers develop the best solution for their products and clients. This is an open source protocol. It’s free software and has no licensing fees.

Blue-tooth hardware is compose of two components. The radio device generates the Blue-tooth signal and the Link Controller is the controller that interacts with the host device. The radio and the Link Controller are the two most important components of a Blue-tooth system. If a mobile phone or tablet is in a location that has an Ethernet network, the LAN must have a wired connection to the host. If a phone or tablet is paired to a computer, it will be unable to communicate with the other devices.
