China CDMA Handset Manufcturing (Bird II) Trevor, Because I post all China wireless things of interest to me, on this lightly trafficked Nokia and Wireless thread, and I have been doing that for some time. Given the quality of the SI search engine, the relatively few posts allow me to search back and retrieve relatively easily. If I feel an article has particular relevance to the Mod Qualcomm thread, I post it there, as I used to do on the "S&P 500" thread and as I did before that on the "Coming Into Range thread". << Doesn't Bird pay GSM royalties and doesn't Bird want to export handsets? >> Royalties are between the IP holders and the manufacturers they license, and in China, maybe MII. The Chinese handset manufacturers, as opposed to the Sino-foreign manufacturers have not been very successful yet exporting and unlike the Sino-foreign manufacturers they are not mandated to export 60% of their production. << Sounds like someone's worked hard on manufacturing a good press release rather than a good phone. >> Purports to be an interview with the prexy of the largest Chinese handset manufacturer, although several of his Chinese competitors out-CDMAed him last year. Break out of China production here: Message 18864437 << Doesn't Bird know that Unicom's GSM system is approaching capacity? >> China Mobile's isn't. In line with actual engineering data of China Mobile, with frequency of 29 MHz (x 2) assigned by Ministry of Information Industry, GSM system capacity of up to 800 Erl/Km2 has been opened in Shenzhen, Shanghai and other big cities through adopting various measures such as frequency multiple re-use, multiple layer coverage, minimum microcell station interval, lowest macrocell station interval and frequency hopping. According to its analysis, the capacity can be further increased to about 1,000 Erl/Km2. At present, GSM frequency assigned to China Mobile has increased to 34 MHz. Therefore, there should not be any doubts for supporting 1,200 Erl/Km2. China Unicom, another mobile communications carrier of China has been assigned 16 MHz (x 2) GSM frequency and 10 MHz (x 2) CDMA frequency. Considering spectrum utilization ratio of CDMA can be 2 times as high as that of GSM, therefore it can be generally regarded that China Unicom owns the same spectrum resource strength as China Mobile does. Thus traffic support strength of 2G/2.5G technology in China can be as high as 2,400 Erl/Km2. If calculated on the basis of one subscriber taking up 0.02 Erl (Chinese standard), then up to 120,000 subscribers /Km2 can be supported. If this data is applied to Beijing City, about 37 million subscribers can be supported in the region within Fourth Ring Road only (310 Km2 in area), far exceeding the total population of Beijing. Therefore it is considered by some experts that if only voice services are taken into accounts, the existing frequency resources in 2G/2.5G of China can support 1 billion subscribers across the country, i.e. which can support mobile communications popularization rate of 75% and more. In fact, there are many countries which have realized mobile communications popularization rate of 75% by adopting 2G/2.5G technology, such as Nordic countries, even Italy, ROK and so on. It is worthwhile to mention particularly HKSAR whose area is 1,000 Km2 , mobile communications groups of more than 5 million subscribers have been supported by 2G technology. The mobile communications popularization rate of China is presently only 12%. Even though high-end subscribers which probably takes more than 10% of mobile communications subscribers in several years ahead demand to use data channel at transmission rate of several hundred Kb/s. The existing spectrum resources in 2G/2.5G can still meet the requirement for network capacity. cicmedia.com << Didn't Sulpuzio go to China to empower the Chinese manufacturers? >> Yup! It's under control. << Doesn't Unicom's policy support CDMA? >> Supports it, supports it, supports it, and supports it. Message 18406386 According to a report 2 weeks ago in Hong Kong's South China Morning Post, China Unicom spent 8.1 billion yuan (US$979 million) in handset subsidies last year, which aided in signing up close to 7 million subscribers ($140/handset). Last year, 60 percent of the company's CDMA users were on handset subsidy plans. Average revenue per user (ARPU) for its CDMA business was 172.2 yuan (US$20.8) per month. But that does NOT take into account its huge handset subsidies. Further promotions could "seriously endanger the company's profitability" according to the Post. - Eric -
