而带宽范围较宽的音频编码采用的则多是基于心理声学的感知编码技术。
However, the audio coding technology for ultra wideband mostly USES perceptual coding which is based on the psychoacoustic model.
相应的技术不再是你所熟悉的802.11—再说了，它所赖以存活的带宽和范围，从来就没有过。
The technology won't be your familiar 802.11-it never had the bandwidth or range to be viable anyway.
当带宽普遍得到改善的同时，惠普，思科还有其他一些公司把这项技术的成本和技术范围都降了下来，因此这个现成的应用技术将会越来越普及。
As bandwidth improves in general, and HP, Cisco, and others bring the cost and scope of the technology down, this ready-made application will grow more popular.
