  • ''Cable Replacement'' 개념으로 시작된 Bluetooth 기술은 많은 장점을 가지고 있으며, 이를 이용한 다양한 Business model이 개발 중에 있다. 이런 Bluetooth 기술은 이동통신 사업자에게는 기회와 위협요인을 모두 지니고 있다. 본고에서는 실제 SK텔레콤에서 개발한 Bluetooth 서비스 기능을 중심으로 설명하고 이동통신 서비스에 적합한 Bluetooth 사업 모델에 대해 언급한다. 현재 개발된 Bluetooth 응용 profile들은 셀룰라폰을 중심으로PAn(Personal Area Network)을 구성하고 다양한 종류의 디바이스기기에서 접속하는 것을 시험하였다. 개발된 응용profile로는 셀룰라폰-노트북간의 Dialup Networking 기능, 셀룰라폰-키보드간의 무선입력 기능 등이다. 이런 기능들을 바탕으로 무선데이터 시장은 더욱 활성화될 것으로 전망되며 기타 유용한 응용분야도 가능하다.

  • Bluetooth 칩셋의 생산량을 보면, 보이지 않는 곳에서 Bluetooth의 성장은 계속 되고 있다. [1] 그리고 Bluetooth는 Scatternet을 구성하여 Personal Area Network의 영역을 넘어 Senssor network에 적용하는 것이 가능하다. 그러나 Bluetooth specification[2]에서는 Scatternet Formation 방법에 대해 제안하지 않는다. 이를 개선하기 위해 BTCP (Bleutooth Topology Construction Protocol)[3], Bluetree[4], Bluenet[5], TPSF(Two-Phase Scatternet Formation) protocol[6]이 제안되었다. 본 논문에서는 이러한 protocol들을 개략적으로 설명하고 그에 대한 장단점을 알아보겠다.

  • Recently, Bluetooth has been regarded as a new technology for short-range wireless connection. Although initial application of Bluetooth technology has been focused mainly on replacing cables between hand-held devices due to a limited packet size and short-range, general wireless telecommunication such as PAN and Ad hoc networks via Bluetooth-equipped devices is expected to be one of the most popular applications. Wireless equipments have been used to exchange data between host and mobile unit. The exchanging data may be several bytes of control command and the value of sensors with ultra-sonic, vision sensor, and encoder from mobile robot. However, most wireless equipments have some drawbacks such as lack of authentication, large size and high price. On the other hand, the benefits of Bluetooth are small size, low power, low price except short-range. Especially, there are some difficulties when wireless modules are used in indoor environments. In this paper, a method of using wire network in Bluetooth network is investigated as a solution to overcome the short-range problem of Bluetooth and difficulty in indoor environment.

  • Bluetooth is a promising wireless personal area network technology and is on the verge of being ubiquitously deployed over wide range of devices. This paper aims to implement a wireless network for image transmission using Bluetooth technology. The characteristics of Bluetooth are small size, low band width and low power consumption, However, there are some difficulties in implementing a wireless radio network using Bluetooth since a lot of repeaters may needed when Bluetooth depends a role of host on personal computer for data transmission. In this paper, a method to implement a wireless radio network is proposed and applied for image transmission using a small size microprocessor for each Bluetooth.

  • In this paper, we aim to design and implement supporting IPv6 Bluetooth Access point(AP) in Linux. Bluetooth is a cable replacement technology designed for short range ad-hoc connections, which most likely change the way we handle and access information in the near future. In Personal Area Network(PAN) mobile devices need many IP address space, then we need next generation Internet Protocol(IPv6). We designed Bluetooth Access Point with Bluetooth stack and MAC bridge function in Linux. The implementation tested on Linux system based on Bluetooth Access Point with other Bluetooth devices.

  • In order for efficient Bluetooth Baseband functional test, Bluetooth SIG (Special Interest Group) provides with Test Suite Structure (TSS) in the Bluetooth specification version 1.1. Bluetooth Baseband hardware which needs to be authenticated should implement the test specification defined in the TSS part I.1 through I.3. In this paper, we discuss the method to verify and test a Bluetooth Baseband implementation based on the TSS version 1.0. Also, we describe various senario and implementation possibilities to perform the Bluetooth Baseband authentication test.

  • Bluetooth is generally called as wireless technology$.$standard$.$product for communicating in a short distance which is in order to implement both-sides short distance telecommunications at low price without complicated electric wires. SIC is the cooperation group which is composed of telecommunications, computer, eminent network firms for technological development and building the market. It actually made a scheme for standardization. SIG, Ericsson takes a main role in SIG. is composed of about 1,800 member companies and the members are increasing continuously. It was announced Bluetooth version 1.0 from SIG August 1999 and the products such as software development kits, core components will come out soon later. In this paper, Bluetooth technological development and the present state of standardization are investigated and analyzed.
