2007, China's mobile telecommunications industry, it is a very special year. From 1987 in Guangzhou to establish the time of analog mobile phones, China's mobile telecommunications industry through 20 years. In the past 20 years, China Mobile Communications from scratch, from small to large and has scored great achievements in the world amazed, and create a global network size First, the number of the users first miracle. TD-SCDMA standard as an international standard 3 G mainstream, and is one of China's mobile telecommunications industry in the world of the enormous contribution. TD-SCDMA commercial trial network in China's large-scale construction in 2007 is, therefore, 2007 is also known as China's "G Year."
April 2007 25-26, the "2007 China Mobile Communication Industry Summit Forum" held in Beijing. The forum 3 G industry in China is fully activated, the "pragmatic network construction, innovative business applications" as the theme, officials from regulatory agencies, the telecommunications industry, experts and members of the chain of University scholars around the "Mobile Communication Industry economic, telecom operators strategies, innovative applications, networking and technical evolution of the 3 G "and other topics in-depth discussions. We evolution, direction, road signs and industrial chain, and other aspects of conduct in-depth interpretation of this Summit Forum.
06 TD-SCDMA significant progress: Technical innovation and continuous improvement (multi-frequency point technology, HSDPA, UpPCH Shifting technology, multi-area joint detection technology, the six elements smart antenna technology); constantly improve equipment performance, equipment type increasingly rich - Rafah as much equipment with the direction of development; days fed the convenience of project implementation significantly improved (cluster cable), indoor distribution technology matures (Multiple System of Road).
2007 TD-SCDMA focus: multi-detection capability of the joint district 1 +3; to achieve single-carrier HSDPA function; TD / GSM / GPRS dual-mode automatic roaming switch; to achieve MBMS multimedia broadcasting business networking feature optimized power consumption of mobile phones to enhance stability and more operational capacity.
Third, the three organizations IMT-Advanced (4G) line Evolution
1, broadband wireless mobile technology the driving force of development:
(1) Market and Technology two and flooding: the whole of human society from the industrial society into an information society; technology breakthroughs and rapid development.
(2) competition and accelerate the integration of technology updates (technical competitions): inter-industry competition and integration (IT and telecommunications, broadcasting and telecommunications); multi-technology market operators under the competition between different technologies manufacturers of camp the competition.
2, the impact of the development of different technologies main factors:
(1) Control and Policy: spectrum allocation, permits, business types;
(2) market demand: network capacity charges, business, (3) the competitiveness of the industry chain: cost and scale.
3,4 G schedule: October 2007 confirmed spectrum → February 2008 issued a circular assembly candidate technology → start by the end of 2008 to 2009 in the assembly candidate technology → 2010 first version of the standard set in 2015 → about business.
