求一篇 关于蓝牙或者四轮定位仪的文章

蓝牙的创始人是瑞典爱立信公司，爱立信早在1994年就已进行研发。1997年，爱立信与其他设备生产商联系，并激发了他们对该项技术的浓厚兴趣。 1998年2月，5个跨国大公司，包括爱立信、诺基亚、IBM、东芝及Intel组成了一个特殊兴趣小组（SIG），他们共同的目标是建立一个全球性的小范围无线通信技术，即现在的蓝牙。

蓝牙的名字来源于10世纪丹麦国王Harald Blatand——英译为Harold Bluetooth(因为他十分喜欢吃蓝梅,所以牙齿每天都带着蓝色)。在行业协会筹备阶段，需要一个极具有表现力的名字来命名这项高新技术。行业组织人员，在经过一夜关于欧洲历史和未来无限技术发展的讨论后，有些人认为用Blatand国王的名字命名再合适不过了。Blatand国王将现在的挪威，瑞典和丹麦统一起来；他的口齿伶俐,善于交际,就如同这项即将面世的技术，技术将被定义为允许不同工业领域之间的协调工作，保持着个各系统领域之间的良好交流，例如计算，手机和汽车行业之间的工作。名字于是就这么定下来了。

关于Bluetooth SIG

Bluetooth SIG(蓝牙技术联盟)是一家贸易协会，由电信、计算机、汽车制造、工业自动化和网络行业的领先厂商组成。该小组致力于推动蓝牙无线技术的发展，为短距离连接移动设备制定低成本的无线规范，并将其推向市场。

Bluetooth SIG在全球设立的办事处的包括：美国西雅图（全球总部）；美国堪萨斯市（美国总部）；瑞典马尔默市（欧洲、中东和非洲地区（EMEA）总部）；中国香港特别行政区（亚太区总部）。

Bluetooth SIG的全体职员包括执行董事麦弗利博士，营销总监Anders Edlund，以及销售人员、工程专家和运营专家等。除了Bluetooth SIG(蓝牙技术联盟)的支援，成员公司的志愿者在经营Bluetooth SIG的过程中也发挥了重要作用。

Bluetooth SIG的发起公司是Agere、爱立信、IBM、英特尔、微软、摩托罗拉、诺基亚和东芝。2006年10月13日，Bluetooth SIG（蓝牙技术联盟）宣布联想公司取代IBM在该组织中的创始成员位置，并立即生效。通过成为创始成员，联想将与其他业界领导厂商杰尔系统公司、爱立信公司、英特尔公司、微软公司、摩托罗拉公司、诺基亚公司和东芝公司一样拥有蓝牙技术联盟董事会中的一席，并积极推动蓝牙标准的发展。除了创始成员以外，Bluetooth SIG还包括200多家联盟成员公司以及约6000家应用成员企业。

[编辑本段]

为什么选择 Bluetooth 无线技术？
Bluetooth 无线技术是在两个设备间进行无线短距离通信的最简单、最便捷的方法。它广泛应用于世界各地，可以无线连接手机、便携式计算机、汽车、立体声耳机、MP3 播放器等多种设备。由于有了“配置文件”这一独特概念，Bluetooth 产品不再需要安装驱动程序软件。此技术现已推出第四版规格，并在保持其固有优势的基础上继续发展 — 小型化无线电、低功率、低成本、内置安全性、稳固、易于使用并具有即时联网功能。Bluetooth 无线技术是现在市场上唯一得到认可的主导短距离无线技术，2005 年底，其周出货量已超过五百万件，已安装基站数超过 5 亿个。

全球可用
Bluetooth 无线技术规格供我们全球的成员公司免费使用。许多行业的制造商都积极地在其产品中实施此技术，以减少使用零乱的电线，实现无缝连接、流传输立体声，传输数据或进行语音通信。Bluetooth 技术在 2.4 GHz 波段运行，该波段是一种无需申请许可证的工业、科技、医学 (ISM) 无线电波段。正因如此，使用 Bluetooth 技术不需要支付任何费用。但您必须向手机提供商注册使用 GSM 或 CDMA，除了设备费用外，您不需要为使用 Bluetooth 技术再支付任何费用。

设备范围
Bluetooth 技术得到了空前广泛的应用，集成该技术的产品从手机、汽车到医疗设备，使用该技术的用户从消费者、工业市场到企业等等，不一而足。低功耗，小体积以及低成本的芯片解决方案使得 Bluetooth 技术甚至可以应用于极微小的设备中。请在 Bluetooth 产品目录和组件产品列表中查看我们的成员提供的各类产品大全。

易于使用
Bluetooth 技术是一项即时技术，它不要求固定的基础设施，且易于安装和设置。您不需要电缆即可实现连接。新用户使用亦不费力 – 您只需拥有 Bluetooth 品牌产品，检查可用的配置文件，将其连接至使用同一配置文件的另一 Bluetooth 设备即可。后续的 PIN 码流程就如同您在 ATM 机器上操作一样简单。外出时，您可以随身带上您的个人局域网 (PAN)，甚至可以与其它网络连接。

全球通用的规格
Bluetooth 无线技术是当今市场上支持范围最广泛，功能最丰富且安全的无线标准。全球范围内的资格认证程序可以测试成员的产品是否符合标准。自 1999 年发布 Bluetooth 规格以来，总共有超过 4000 家公司成为 Bluetooth 特别兴趣小组 (SIG) 的成员。同时，市场上 Bluetooth 产品的数量也成倍的迅速增长。产品数量已连续四年成倍增长，安装的基站数量在 2005 年底也可能达到 5 亿个。

Bluetooth is the founder of the Swedish Ericsson, Ericsson has been back in 1994 for research and development. 1997, Ericsson and other equipment manufacturers links and inspire them to the great interest in the technology. February 1998, five large multinational companies, including Ericsson, Nokia, IBM, Toshiba and Intel formed a special interest group (SIG), their common goal is to create a global and small-scale wireless communication technologies, Now the Bluetooth.

Bluetooth name from the 10 century Danish King Harald Blatand - for the English translation of Harold Bluetooth (because he likes to eat very blue-mei, the teeth every day, with blue). Trade associations in the preparatory stage, the need for a performance of a very named after the high-tech. Industry members, after a night on the European history and the future development of unlimited technical discussions, some people think that using Blatand named after King will appeal. Blatand King will now Norway, Sweden and Denmark reunification; his Kouchi Lingli, be good at communication, like the upcoming technology, technology will be defined to allow different industrial areas of coordination between the work and maintained a system of the The area between the good exchange, for example, mobile phones and between the automotive industry. Name was on such a set.

On the Bluetooth SIG

Bluetooth SIG (Bluetooth SIG) is a trade association, from the telecommunications, computer, automobile manufacturing, industrial automation and network industries leading manufacturer of components. The team is committed to promoting the development of Bluetooth wireless technology to connect mobile devices short-range wireless standard developed low-cost, and to market.

Bluetooth SIG in the world, including the establishment of the Office: Seattle (global headquarters); Kansas City (U.S. headquarters); Sweden in Malmo (Europe, Middle East and Africa (EMEA) headquarters); Hong Kong SAR, China (Asia-Pacific headquarters).

Bluetooth SIG of the staff, including Executive Director Dr. Mai Fuli, marketing director Anders Edlund, and sales personnel, engineering experts and operators, and other experts. In addition to Bluetooth SIG (Bluetooth SIG) support, members of the volunteer companies operating in the process of Bluetooth SIG has also played an important role.

Bluetooth SIG is the launching of Agere, Ericsson, IBM, Intel, Microsoft, Motorola, Nokia and Toshiba. October 13, 2006, Bluetooth SIG (Bluetooth SIG) announced the Lenovo replace IBM in the organization of the founding members of position, and take effect immediately. Through a founding member, Lenovo will work with other industry leading provider of Agere Systems, Ericsson, Intel, Microsoft, Motorola, Nokia and Toshiba have the same Bluetooth SIG board of directors of one seat, and actively promote the Bluetooth The development of standards. In addition to founding members outside, Bluetooth SIG also includes more than 200 members of the League of the company and about 6,000 members of enterprise applications.

Bluetooth technology advantages
[Edit this paragraph]

Why Bluetooth wireless technology »
Bluetooth wireless technology equipment is conducted in two short-distance wireless communication is the easiest and most convenient way. It widely used around the world, wireless connectivity mobile phones, portable computers, cars, stereo headphones, MP3 players and other equipment. With the "profile" of this unique concept, Bluetooth products are no longer need to install driver software. The technology is available now fourth specifications, and maintain its inherent advantages on the basis of the continued development - small radio, low-power, low cost, built-in security, secure, easy to use and have instant networking capabilities. Bluetooth wireless technology is now the only recognition of the dominant short-range wireless technology, the end of 2005, the week has shipped more than 5 million, the number of base stations already installed more than 500 million.

Global available
Bluetooth wireless technology specifications for our member companies worldwide use free of charge. Many industry manufacturers have actively in the implementation of its products in this technology to reduce the use of Lingluan of wires and achieve seamless connectivity, stereo transmission, transmission of data or voice communications. Bluetooth technology in the 2.4 GHz band operation, the band is a need not apply for a permit of industry, science and technology, medical (ISM) radio frequency. For this reason, the use of Bluetooth technology does not need to pay any fees. But you must register to use the GSM mobile phone provider, or CDMA, in addition to equipment costs, you do not need to use Bluetooth technology to pay any fees.

The scope of equipment
Bluetooth technology has undergone an unprecedented wide range of applications, the technology integration of products from mobile phones, automobiles to medical equipment, the use of the technology users from the consumer, industrial enterprises, and so on to the market, and so on. Low power, small size and low-cost chip solution makes Bluetooth technology can be applied even in Jiwei Xiao equipment. Bluetooth products in the directory of products and components in the list view of our members to provide a range of products Daquan.

Easy to use
Bluetooth technology is a real-time technology, it does not require a fixed infrastructure, and easy installation and set-up. You do not need cable to connect to. New users do not easy - you just have Bluetooth brand products, check the available profile, to connect to use the same profile of another Bluetooth device. The PIN codes follow-up process just as your ATM machine in operation just as simple. When they go out, you can take your Walkman personal local area network (PAN), or even with other network connection.

GM's global specifications
Bluetooth wireless technology is on the market today supports the most extensive, most feature-rich and secure wireless standard. The world's accreditation procedures to test whether the members of the sub-standard products. Since the 1999 release Bluetooth specification, a total of more than 4,000 companies become the Bluetooth Special Interest Group (SIG) members. At the same time, Bluetooth products on the market have multiplied the number of rapid growth. The number of products has been four consecutive years have increased the number of base stations installed at the end of 2005 may reach 500 million.
