Bluetooth is a technology specification that wirelessly connects portable PCs, mobile phones and other mobile devices at low cost within a narrow range. It uses radio frequencies to communicate voice and data without the need for physical cables for communication between digital devices.

For example, when Bluetooth technology is implemented in mobile phones and laptops, you no longer need to use the cumbersome cables you currently use to connect mobile phones and laptops. Bluetooth technology can be applied to virtually any digital device, including printers, desktops, fax machines, keyboards and joysticks.

Bluetooth was launched as an open standard when five companies, Ericsson, Nokia, Intel, Toshiba and IBM, formed a consortium called the Bluetooth Special Internet Group (SIG) in 1998. Since then, Lucent Technologies, Motorola, Microsoft, and 3Com have joined the SIG, and its current membership has continued to grow, and Bluetooth is now establishing itself as a global standard for short-range wireless communications.

The specification and characteristics of Bluetooth are as follows.

First, the Bluetooth Radio module uses a 2.4GHz ISM (Industrial Scientific Medical) method to provide a maximum rate of 1Mbps. In addition, a frequency hop transceiver technique is applied to reduce the effects of fading interference, and a modulation scheme uses a binary FM method.

Baseband modules deliver baseband protocols and provide routing to low-level links from remote devices, Link Manager Protocol (LMP) provides link control such as link setup, and L2CAP The Logical link Control and Adaptation Protocol module provides upper layer protocol multiplexing, packet fragment reassembly, and quality of services (QOS). RECOMM is also an upper layer of L2CAP and provides the function of transmitting data transmitted from the application layer.

In addition, Bluetooth is a protocol that provides a short-range wireless link function between electronic devices in a home and an office (radius 10m), and configures an ad hoc network between stationary and mobile devices to enable file transfer, dial up networking synchronization, and 3 in 1 phone. , Ultimate Handset, Computer Speak phone, Cordless Computer and Conference Table.

Accordingly, Bluetooth is installed in devices such as printers, PDAs, desktops, fax machines, keyboards, joysticks, and the like to provide voice and non-voice services wirelessly.

The wireless access technology provided by Bluetooth is based on ad hoc network and provides data service using TCP / IP in the piconet environment and interface functions such as host interface device (HID), object exchange protocol (OBEX) and audio. to provide. Bluetooth Radio provides fast sensing of the environment and frequency hopping to provide a stable link in noisy environments.

In addition, compared to other systems using the same frequency band, it has the advantage of excluding interference by other signals as much as possible by using a small packet and a hopping function to a new frequency quickly. In particular, Bluetooth Radio can reduce the effects of random noise generated in a long-distance link environment through FEC (Forward Error Correction) for error recovery.

Bluetooth transmission provides a full-duplex approach that combines circuit and packet switching modes based on time division duplex (TDD). Packets used in Bluetooth generally use one TDD slot, but can be extended to five slots.

The TDD slot has characteristics of providing synchronous and asynchronous channels, providing one asynchronous data channel and up to three synchronous voice channels, and supporting synchronous voice channels of 64 kb / s.

Asynchronous channels provide up to 57.6 kb / s in the carrier direction, up to 432.6 kb / s in the symmetrical link, and up to 721 kb / s in any direction. It consists of radio unit, link control unit, link management unit, and software function unit.
