查询词典 high-frequency telephony

DayStar works on the principle that even minute modifications of the solar material could help create flexible, efficient, and lightweight solar cells for commercial and military customers. Applications range from portable power units to high-altitude airships (for cellular telephony and related communications). In particular, CIGS-based solar cells are extremely resistant to harsh conditions and are considered 'self repairing' accounting for their unusually long lifespan, making them well suited for near space and orbital applications.

日星严谨的工作致力于太阳能电池的完善，按照柔性高效轻便的原则，甚至是极细微的一些改造都不放过，以求最大限度的满足商业和军事的客户要求；其应用范围从便携动力单元到高空飞艇或移动电话和其他相关通讯设施，尤其特别的是，CIGS太阳能电池对各种苛刻环境的高适应性和自我修补性非常之好，这建筑于这类电池特别的长寿特性，使得他们能用于外太空的一些应用上

Long distance telephony was also an option, but costs were very high and it often sounded as if the other party was speaking from inside some kind of echo chamber on a distant planet.

当然，长途电话也是一个选择，但价格十分昂贵，而且话筒另一边的声音听起来总像是从一个遥远星球的回音室里传来的。

New areas of focus include IP telephony, high-end teleconferencing, and other services that rely on data networks

新的关注领域包括IP电话、高端电话会议，以及依赖于数据网络的其它服务。

The current second-generation and third-generation (3G) mobile communication systems operate with narrow audio bandwidth limited to 200-3400Hz.As wireless systems are evolving from voice-telephony dominated services to multimedia and high-speed data services, the introduction of a wider bandwidth of 50–7000 Hz speech codec which provides substantially improved speech quality and naturalness is quite necessary. The Adaptive Multi-rate Wideband speech codec which was selected by 3GPP/ETSI and ITU-T can provide natural, present and comfortable codec speech and have higher intelligence and robustness in wireless systems. A wide range of applications are envisioned for AMR-WB, including ISDN wideband telephony and audio/video teleconferencing,Voice over IP and Internet applications such as IP video conferencing, voice mail, voice chat, broadcast, and voice streaming.

随着现代无线通信特别是多媒体通信的发展，人们对语音通信的质量要求越来越高。3GPP/ETSI TS026和ITU-T 722.2标准确定的自适应宽带语音编解码器AMR-WB具有的低比特率、互操作性和高语音质量，使之不仅能够应用于无线通信领域，而且可广泛应用于其他各种通信系统和平台，包括：VoIP、因特网、PSTN高质量音频会议、音频流、ISDN宽带电话、ISDN可视电话和电视会议等。
