摘要
无线个域网(WPAN)是一种与无线广域网(WWAN)、无线城域网(WMAN)、无线局域网(WLAN)并列但覆盖范围相对较小的无线网络。WPAN所覆盖的范围一般在10m半径以内,必须运行于许可的无线频段。WPAN能够有效地解决"最后的几米电缆"的问题,进而将无线联网进行到底。阐述了无线个域网基本概念、网络分类及特点,并将其与无线局域网进行简单比较,同时对相关技术进行了分析。
As a kind of wireless network, WPAN is in parallel with WWAN, WMAN and WLAN but with comparatively smaller coverage. WPAN runs on licensed frequency band, and its coverage radius is about 10 meters. The significance of WPAN is that it can help to solve the ＂last few meters access＂ issue. In this article, the basic concepts, classification and characteristics of WPAN have been expounded and compared with WLAN; the relevant technologies have been analyzed.
