时分多址(TDMA)和码分多址(CDMA)这两种数字蜂窝技术孰优孰劣的争论,是过去两年中蜂窝系统业的最热门话题.但是,TDMA的支持者说,真正的争论焦点并非是CD-MA与TDMA孰优孰劣,而在于哪一种技术更可行,哪一种技术建立了业已证明有效的体系结构.TDMA的支持者指出,CDMA只不过还在继续进行现场试验,而TDMA已经投入商业应用并且正在向其第二代迈进.对美国的蜂窝系统电信公司来说,若要在当前和未来具有数字技术的优势,则只有一个切合实际的选择——TDMA.McCaw蜂窝通信公司董事长Craig McCaw说:“我们在前一段时间决定向我们客户提供现代化的服务.我们丝毫不怀疑TDMA是一种好技术,它现在就可提供使用.这正是我
The debate over which of the two digital cellular technologies, Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA), is the hottest topic in the cellular system industry over the past two years, however, says TDMA backers say the real The focus of the debate is not whether CD-MA or TDMA is better, but which technology is more viable and which technology has built a proven architecture. TDMA supporters point out that CDMA is just continuing on-site Test, and TDMA has been put into commercial use and is moving towards its second generation. For US cellular telecommunications companies to have the current and future digital technology advantages, there is only a realistic choice - TDMA. Craig McCaw, Chairman of McCaw Cellular Communications, said: "We decided a while ago to offer our customers a modern service. We have no doubt that TDMA is a good technology and it is available for use now.
