Xiaolingtong

Xiaolingtong (also known as PAS - Personal Access System) is the wireless extention for wired telephone system in China. It acts like a mobile phone but only good within the local calling region, which is usually a single metropolitan area.

It uses 32K ADPCM (See pulse-code modulation) as its digitization technique. Xiaolingtong supports many more features than the traditional wired phone system such as high speed wireless Internet connection (32K/64K), Web access, emailing, text messaging and even color image transfering.

China Telecom operates a PAS system in China, even though technically it is not allowed to provide mobile services. One of the largest vendors of the system is UT Starcom.

In India, a related system is corDECT, and in Japan, there is a similar system called PHS (Personal Handy-phone System).
