自1989年英国提出世界上第一个数字无绳电话标准——CT2,距今已有6年时间,尽管相继又有几种数字无绳电话标准推出并完成,但商用进展缓慢,仍处于商用试验阶段,这也反映出各国谨慎发展的态度。鉴于国内有关这方面的研究已较多,本节将归纳比较各种数字无绳电话标准,然后分析最新市场发展,并分析背景原因。 1.数字无绳电话标准 目前已推出的影响较大的数字无绳电话标准有CT2、CT2+、CT3、DECT、PHS、PACS等,主要技术指标列于下
Since the United Kingdom put forward the world’s first digital cordless phone standard - CT2 in 1989, it has been 6 years since it launched commercialization of several digital cordless telephone standards and has completed its commercial success, but it is still in commercial trials This also reflects the cautious attitude of all countries. In view of the domestic research on this area has been more, this section will summarize the various digital cordless phones standards, and then analyze the latest market developments, and analyze the background. 1. The digital cordless phone standards currently have a greater impact on the digital cordless phone standards CT2, CT2 +, CT3, DECT, PHS, PACS, etc., the main technical indicators are listed below
