代表电信系统的 xDSL 和有线电视系统的 HFC 目前是最热门的接入方式,似乎未来的有线宽带接入技术非 xDSL 和 HFC莫属。尤其国外 ADSL 和 HFC 网络日益普及更使我们确信只有xDSL 和 HFC 才是“最后一公里”的主流方案。而近期开始流行房地产界的“智能小区”却没有采用上述技术,是房地产商外行还是我们错了?
HFCs representing xDSL and CATV systems for telecom systems are by far the hottest access options and it seems unlikely that future cable broadband access technologies would be non-xDSL and HFC. In particular, the growing popularity of foreign ADSL and HFC networks makes us convinced that only xDSL and HFC are the “last mile” mainstream programs. The recent popular real estate community “smart community” did not use the above technology is the real estate business or we are wrong?
