虽然 WLAN(无线局域网)由于安全标准的不确定性,严重阻碍了其发展的步伐,但利用基于 WLAN 的 VoIP 来代替或补充目前现有的电话系统,如通过笔记本电脑、PDA 或者新型的 Wi-Fi 电话与 WLAN 语音服务器连接,将成为了促使 WLAN 广泛应用的亮点之一, 换占之,无线网络上跑语音即将成为现实。作为一种成熟的网络通信技术,VoIP 在有线网络已逐渐开始广泛应用,而基于 WLAN 的 VoIP 技术以与之相补充显示了其市场潜力。虽然目前在无线网络上实现 VoIP 还面临着无线吞吐量的波动、热点间漫游、Wi- Fi 电话终端缺乏等问题的困扰,但基于 WLAN 的 VoIP 应用代表了市场发展的趋势。可软硬件实现基于 WLAN 的 VoIP 实现可通过软硬来实现,其工作方式分为两个部分。一是基于 SpectraLink、Symbol Technologies Inc．Cisco 等公司的
Although the WLAN has seriously hampered its development due to the uncertainty of security standards, WLAN-based VoIP has been used to replace or supplement current existing telephone systems such as laptops, PDAs or the new Wi- Fi phone connected to a WLAN voice server will be one of the bright spots that will make WLANs popular. Switching voice over wireless networks is about to become reality. As a mature network communication technology, VoIP has gradually begun to be widely used in the wired network, and the VoIP technology based on WLAN complements the potential of the market. Although the current implementation of VoIP over wireless networks is also hampered by fluctuations in wireless throughput, roaming between hotspots and the lack of Wi-Fi telephony terminals, VoIP-based WLAN applications represent a market trend. Hardware and software can be achieved WLAN-based VoIP implementation can be achieved through hardware and software, and its work is divided into two parts. One is based on SpectraLink, Symbol Technologies Inc. Cisco and other companies
