机构简介：

　　The Study Groups of ITU’ s Telecommunication Standardization Sector (ITU-T) assemble experts from around the world to develop international standards known as ITU-T Recommendations which act as defining elements in the global infrastructure of information and communication technologies (ICTs). Standards are critical to the interoperability of ICTs and whether we exchange voice, video or data messages, standards enable global communications by ensuring that countries’ ICT networks and devices are speaking the same language.

　　International ICT standards avoid costly market battles over preferred technologies, and for companies from emerging markets, they create a level playing field which provides access to new markets. They are an essential aid to developing countries in building their infrastructure and encouraging economic development, and through economies of scale, they can reduce costs for all: manufacturers, operators and consumers.
