无线 LAN 市场正在迅速扩大,推动这个市场发展的两项技术是 HiperLAN(www.hiperlan.com)和 Bluetooth(蓝牙,www.bluetooth.com)。HiperLAN是下一代的高速无线 LAN 技术,其传输速率高达25Mbps,有效覆盖距离为10米。本文将详细介绍 HiperLAN2和Bluetooth 这两种对未来有着极大影响的技术。市场动力推动 LAN 市场发展有许多因素,其一是产品的价格,如无线网卡的价格已经从原来的200美元降到现在的100美元左右,用于 Apple 机的 IEEE 802.11b 网卡美国售价为99美元,因而无线产品已经具有一定的性能价格比优势。其二是标准,无论是官方制定的标准还是工业标准,都推动了无线市场的发展,PC 网卡的普及也起推波助澜作用。其三,Cisco、Nortel、Nokia 和 Ericsson 也加入到无线市场的竞争之中。其四,宽带 Internet 接
The wireless LAN market is rapidly expanding and the two technologies driving this market are HiperLAN (www.hiperlan.com) and Bluetooth (Bluetooth, www.bluetooth.com). HiperLAN is the next generation of high-speed wireless LAN technology with transmission rates of up to 25 Mbps and effective coverage of 10 meters. This article details HiperLAN2 and Bluetooth, two technologies that have a significant impact on the future. Market Dynamics There are many factors driving the development of the LAN market. One is the price of the product. For example, the price of a wireless network card has dropped from the original $ 200 to the current $ 100. The IEEE 802.11b card for the Apple machine is priced at 99 Dollars, so wireless products already have a certain cost performance advantages. The second is the standard, whether it is the official development of standards or industry standards, have promoted the development of the wireless market, PC network card also played a role in promoting the popularity. Third, Cisco, Nortel, Nokia and Ericsson also join the wireless market competition. Fourth, broadband Internet access
