虽然经历了数年的试验,电力线宽带上网(BPL)被证实更适合于家庭上网而不是宽带接入,但BPL依然在打破接入壁垒方面显示了突出优势,这要感谢无线宽带的应用。无线宽带接入技术已经在亚洲特别是发展中国家得到应用,在铜线上网状况不佳或根本就没有铜线的地方,DSL补充或取代了铜线。但在面对多住户单元(MDUs)时,无线宽带在室内覆盖上遇到了麻烦。摩托罗拉亚太地区无线宽带主管Ray Owen博士说:“受物理规律影响,我们无法在MDUs的地下室里保证无线宽带100％可靠。”摩托罗拉的解决方案是将无线宽带引入这类住宅,然后用网关将以太网信号转化为BPL信号,后者可以通过住
Despite several years of experimentation, Powerline Broadband Internet (BPL) has proven to be more suitable for home networking than broadband access, but BPL is still showing significant advantages in breaking barriers to entry, thanks to wireless broadband adoption. Wireless broadband access technology has been applied in Asia, particularly in developing countries where DSL supplements or replaces copper where the copper is in poor condition or there is no copper at all. But in the face of multi-dwelling units (MDUs), wireless broadband is having trouble with indoor coverage. Ray Owen, Head of Wireless Broadband at Motorola Asia Pacific, said: “Due to physical laws, we are unable to secure 100% reliable wireless broadband in the MDUs’ basements.” Motorola’s solution is to introduce wireless broadband to such homes and then gateway the Ethernet Network signal into BPL signal, the latter can live
