China (country regulation overview)

The Chinese telecoms market is potentially vast due to China’s enormous population and high GDP growth. During 2009, it has attracted much attention due to impressive subscriber growth across various telecoms services, with increasing levels of competition between the major operators.

China’s fixed market is a duopoly, with China Telecom and China Unicom the two dominant providers of local fixed network services. In the broadband market, there has been strong growth in 2009 and subscribers already number more than 100 million. Nevertheless, there is still considerable growth potential in the next few years in terms of household penetration.

In the mobile market, there are three network operators - China Mobile, China Unicom and China Telecom. At the beginning of 2009, the three operators were granted 3G licences with different standards - TD-SCDMA, WCDMA, and CDMA/EV-DO respectively. China Mobile favours rollout of TD-LTE to maintain its dominant position, and announced a trial service in Shanghai in 2010. With 3G network rollout in most cities of China, there is significant potential for the development of wireless broadband services.

CDMA Technology CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time, and it is the common platform on which 3G technologies are built. CDMA is a "spread spectrum" technology, allowing many users to occupy the same time and frequency allocations in a given band/space. As its name implies, CDMA assigns unique codes to each communication to differentiate it from others in the same spectrum. In a world of finite spectrum resources, CDMA enables many more people to share the airwaves at the same time than do alternative technologies.

LDPost All About CDMA Today there are two major standards for cell phone technology. CDMA and GSM. Almost all phones in the United States operate on either of these networks. However, the average person tends to be unfamiliar with these terms. Common cell phone service providers like Verizon and Sprint use CDMA technology, while carriers like T-Mobile, and Cingular operate on the GSM network.

Radio-Electronics.Com The Basics of IS-95, cdmaOne IS-95 was the first CDMA system to gain widespread use and is found widely in North America. Its brand name is cdmaOne and the initial specification for the system was IS95A, but its performance was later upgraded under IS-95B. It is this later specification that is synonymous with cdmaOne. Apart from voice the system is also able to carry data at rates up to 14.4 kbps for IS-95A and 115 kbps for IS-95B.
RTX TD-SCDMA (12/02, PDF) China’s chance TD-SCDMA (3G) mobile technology has enormous potential in the largest mobile market in the world, with sales of over five million handsets a month. China has no wish to be dependent on Western technology, and this has led to investment in the new standard. TD-SCDMA enables the rapid spread of telecommunications to thinly populated areas, and the broad transmission bandwidth also provides access to the Internet.

WAP Forum Where Does WAP fit in? WAP brings Internet content and advanced services to digital cellular phones and other wireless terminals. WAP is a global wireless protocol specification that works across the following wireless network technology types: GSM (900, 1800 & 1900MHz), PDC, CDMA (IS-95 and/or IS-707), US-TDMA (IS-136), iDEN (ESMR), DataTAC, Mobitex, CDPD, DECT, PHS, FLEX, and ReFLEX. Applications using WAP are scaleable across a variety of transport options and device types. A common standard offers potential economies of scale, encouraging cellular phone and other device manufacturers to invest in developing compatible products. With WAP, cellular and other wireless network carriers and content providers are able to develop new differentiated service offerings as a way to attract new subscribers, while consumers benefit from more and varied choices in mobile communications applications, advanced services and Internet access.
