到目前为止,电缆连接已成为信息机器发展的难题,信息机器在家里的使用受到了限制。手机使“屋外”的网络连接成为可能,在“屋内”蓝牙技术则起到这种作用。“蓝牙”(BIuetooth)是由爱立信公司、东芝公司、诺基亚公司、英特尔公司和国际商用机器公司等公布的一种无线数据与语音通信的开放性全球规范,是90年代中后期才开始开发的,目前已有数千家公司加入。“蓝牙”技术实际上是一种短距离无线通信技术。开发该技术的目的,是希望能以低成本、近距离、无线为基础,为固定与移动设备建立特别的连接。在不久的将来,无线连接的对象还将扩大到电视、空调、洗衣机等家电产品。不仅家电产品将不再需要繁琐的电缆连接,而且个人的生活方式也将因此发生改变。人们热切期待蓝牙技术成为“家庭信息化的王牌”。 So far, cable connections have become a challenge for the development of information machines, and the use of information machines at home has been limited. Cell phones make it possible to connect “outside the house” to the Internet, and “in-home” Bluetooth technology can do that. “BIu Bluetooth” is an open global standard for wireless data and voice communications announced by Ericsson, Toshiba, Nokia, Intel Corporation, and International Business Machines Corporation. It was only developed in the late 1990s. There are already thousands of companies joining. “Bluetooth” technology is actually a short-range wireless communication technology. The purpose of developing this technology is to establish a special connection between fixed and mobile devices based on low cost, short distance and wireless. In the near future, the target of wireless connection will also be expanded to household appliances such as TV, air conditioner and washing machine. Not only do home appliances no longer require tedious cable connections, but personal lifestyles will change as well. People are eagerly looking forward to Bluetooth technology becoming the “ace of household informationization.”
