re: TD-SCDMA in China << First test trials of TD-SCDMA are expected by the end of the year or early in 2002, he said. >> "To promote TD-SCDMA, Datang and Chinese carriers like China Mobile and China Telecom established the TD-SCDMA Forum last year, which has now over 200 members, including Nokia, Motorola, and Alcatel, as well as domestic Chinese vendors like ZTE Corp and Eastcom." >> China-Developed 3G Mobile Technology To Be Tested This October Jun 18, 2001 Interfax Information Services China will launch a large-scale field trial of TD-SCDMA this October, and the whole test will last for about one year. Major domestic telecom operators, China Mobile, China Unicom and China Netcom, plus an as-yet-undecided operator, will participate in the test, said Li Shihe, a major researcher of TD-SCDMA. Li is also the deputy chief engineer of Dang Telecom, a leading telecom equipment provider backed by China's telecom regulator Ministry of Information Industry (MII). The first phase trial of the TD-SCDMA will be based on the existing GSM systems, and the first commercialized TD-SCDMA systems are scheduled to launch in the second quarter of 2002, Zhongguo Ribao quoted Li as saying. The second phase of the trial, which focuses on the development of TD-SCDMA products, will be based on the IP networks at the end of this year. Commercial products from that trial are scheduled for release in 2003 or 2004, according Li. As one of the 6 3G mobile communications standards, TD-SCDMA was jointly developed by China Academy of Telecommunications Technology (CATT), a subsidiary of Datang Telecom and Germany's Siemens. Siemens has vowed to invest USD 100 mln in the development of TD-SCDMA, while Datang has already invested several millions of U.S. dollars in that technology. To promote TD-SCDMA, Datang and Chinese carriers like China Mobile and China Telecom established the TD-SCDMA Forum last year, which has now over 200 members, including Nokia, Motorola, and Alcatel, as well as domestic Chinese vendors like ZTE Corp and Eastcom. Compared to the Europe-supported W-CDMA standard and the Qualcomm-backed cdma2000 technology, TD-SCDMA allows operators to build a 3G network with a comparatively low cost and to utilize the 3G spectrum of services more efficiently, with technologies like smart antennas, joint detection and up-link synchronization. Industry analysts expect that the Chinese government would give its full support to promote the TD-SCDMA technology, as it is China's first-ever domestically developed 3G mobile communications. << - Eric -

what Yiu called “frugal” handsets China's income-constrained agricultural sector, however, will adopt what Yiu called “frugal” handsets that eliminate features such as displays and reduce service fees by offering prepaid pay-per-call debit cards. Some thoughts, comments??: SMS messages (needing a display) is considered important for farmers,etc in Africa, as they can get the world market prices from London just before they start negotiating prices with the local buyers. Additionally SMS messages are more efficient, cheaper than voice messages, not just in terms of cell size and capacity but also in terms of network backbone, long distance calls, etc. (but the chinese writing is obviously a problem I'm not familiar with) Some of this with the background of my buddy in Africa, with a GSM phone since one year (still has a "radio-phone", ordinary phone running on some weird 12 channel radio thing for the whole farming neighborhood, obviously no internet access through that, not even 300bps for email) Also, what could the cost ratio be between a typical chinese infrastructure and the total cost of the handsets it serves with or without displays?? But it still seems an efficient thing to do to start with, (also have??) "frugal" phones, considering that the infra is a long term investment, subsidy, the payback comes through many other mechanims than regular operator revenues?? If a handset is really frugal, at what point is the battery the most expensive thing?? And needing renewal every now and then?? (one older relative has kept this NMT non-chargable battery powered Motorola going for years, only using it when going where there might be reason to either receive or make a call, but last year switched to a regular GSM because recharging was cheaper,easier than buying regular batteries twice a year, now the phone is "always on", even receives SMS messages) Ilmarinen PS. That is, even me remembers when a bicycle or walking was the way to go places, not just to be hip and green and show off that really nice latest fashion and style cycle. She remebers when our phone number became 14, the ring tone was different depending on who called and one had to speak louder for long distance. The point how important "connecting people" is. (I'm still waiting for the "elderly phone", big display and big buttons, hearing aid, "I've fallen and can't get up" button, etc, Benefon lost that) P.P.S. Without connecting the mutual problems of elderly care, mobility of work force,etc.. P.P.P.S Prepayed cards are obviously great where one cannot pay telephone bills with WAP.
