当前的主流无线联网技术,可以说有两大分支:无线局域网(WLAN)和蓝牙(HomeRF和HyperLAN2的影响力颇为有限,还难以与它们相提并论),在市场上,WLAN的地位又显得更为显著。下文将从“纵”、“横”两个方面来探讨这两大技术。需要指出的是,蓝牙的前景如何,业界尚无统一的意见。一方面,爱立信等公司在推出新款的蓝牙手机;另一方面,英特尔这等蓝牙特别兴趣小组的成员却在对其前景表示忧虑。但是,无线局域网就完全不一样了。无论是厂商还是运营商乃至第三方咨询机构都对其大摇橄榄枝,有所差异的只是对其普及的时间和增长的幅度看法有所区别罢了。据第三方咨询机构预测,到2004年年底,会有30％的笔记本电脑配备无线网卡。无线局域网增长的主要因素包括:全球商业化及电子商务的增长;便携式电脑使用率的增长;互联网成为信息交流的主要应用平台;电子邮件使用量的增长;弹性工作的增长;地点转换会引起生产力的降低。 There are two main branches of the current mainstream wireless networking technology: WLAN and Bluetooth (HomeRF and HyperLAN2 have limited influence and can not be compared with them). In the market, the status of WLAN is more Significant. The following will be from the “vertical”, “horizontal” two aspects to explore these two technologies. It should be pointed out that the future of Bluetooth, the industry there is no uniform opinion. On the one hand, companies such as Ericsson are introducing new Bluetooth handsets; on the other hand, members of the Bluetooth Special Interest Group, such as Intel, are expressing concerns about their prospects. However, wireless LAN is completely different. Both manufacturers and operators as well as third-party consulting agencies shake their branches of olives, the difference is only the popularity of their time and the extent of growth difference between Bale. According to the third-party consultancy forecast that by the end of 2004, 30% of notebook computers will be equipped with wireless network cards. Key growth drivers for WLAN include: global commercialization and e-commerce growth; increased use of laptops; the Internet as a key application platform for information exchange; increased use of e-mail; increased flexibility in work; The reduction.
