New China net (2003-01-25 14:21:31)
High passes the research institute the front staff thinks, says from the technology, the Chinese operation business " the 3g choice " the way is diverse, all is undecided
Center the telecommunication (0728-hk) the first turn of purchase soon starts, has 6 provincial levels subsidiary companies prepares elects, chooses 5 from the center, is not slightly same with before this the media report.
The Fujian telecommunication Quanzhou subsidiary company secret is experimenting CDMA2000, this standard is global three big mainstreams 3g standard - USA'S CDMA2000, Europe's WCDMA, China's TD-SCDMA one. Before this some news said, from the information security and the protection nation industry in order to, China's solid speech operation business - telecommunication and the net passes all very possibly when obtains the 3g handset license plate in this year, uses arrogant Tang telecommunication nation standard TD-SCDMA.
The Fujian telecommunication is the Chinese telecommunication group's sub- company. The CDMA2000 starter is USA high passes the company.
Experiments CDMA2000
The Fujian telecommunication news public figure tells " finance and economics Times ", the group company most worries the matter, is is assigned to accept the Chinese standard. Therefore, the group high level unceasingly is soliciting support the letter produces, attempts independently to choose. " This time experiments, uses is CDMA2000 ??, by no means from 2.5g small quick ?? promotion. Perhaps may regard as is the Chinese telecommunication tendency ".
The Beijing one telecommunication expert states: " Because 2.5g small quick estimate cannot have too many, therefore, telecommunication ???? CDMA2000 definitely may understand. Moreover, the promotion actually is the misunderstanding - even if only remains one mere show, the inside thing all trades the accent, also may say it are the promotion."
First states the news public figure refuses to disclose any detail, " the Quanzhou company is one very market company, in Fujian Province, is it first develops the small quick service ".
Is worth paying attention, the letter produced the authority is suffering several big operations businesses the challenge, the telecommunication and the net passes recently a series of markets operation, like small quick made the potential, Guangdong IP dials the number conflict as well as " the handset rest station ", was the evident proof. " Perhaps the telecommunication can take cancel these services as the condition, receives in exchange chooses the 3g standard the freedom ".
If the telecommunication finally accepts the CDMA2000 standard, to the correlation equipment business said without doubt is the advantage is good. High passes may receive the more patents expense, but the domestic equipment business like resurgence communication (000063), China for may sell more products. " So long as does not use TD-SCDMA, regardless of accepts CDMA2000 or WCDMA, speaking of telecommunication itself, affects is not all big ".
The Chinese standard is been desolate
In October, 2002, the Chinese letter produces makes the plan to the 3g frequency spectrum. Now, three big standards? JCDMA2000, WCDMA, TD-SCDMA? The K camp already formed, the license plate provided the plan also in the government considers - the 3g frame as if basically determined.
Before this, has the many fields public figure thinks the Chinese telecommunication uses the WCDMA standard the possibility is quite big, " it will hold the global approximately 80% market share ". First states the news public figure tells " finance and economics Times ", the Fujian telecommunication also once experimented the WCDMA standard, but the effect as if certainly not specially satisfied. " Only, also cannot absolutely say, the telecommunication certainly cannot accept this standard ".
CDMA2000 is the American 3g standard, already used is center the League of Nations which this was standard passes. But, this standard is regarded as by some telecommunication experts high passes fries does.
" High passes the CDMA2000 standard, printed it before IS-9C5b (the 2g standard) wanted to be thicker than 6 times, but, above 80% were adds something superfluous and ruins the effect, picks off also can as usual work. What the CDMA technology is most essential is the power control, says from this aspect, CDMA2000 only is the IS-9C5b promotion, however it high are actually passed fry do the 3g standard." Wang Xin tells " finance and economics Times ". Wang Zeng in the research institute which high passed is in office, now organized own company.
Some news said, center will move (0941-HK) the parent company China migration group accepts European standard WCDMA, in order to will carry on the promotion to its existing GPRS system. But, Wang is sceptical to this news: " Said from the technology, GSM, the GPRS system and the 3g standard is not certainly compatible, therefore, except WCDMA, the migration definitely may accept other standard. CDMA2000 commercial gender ratio WCDMA is good, moreover, looks from the cost, former is approximately cheaper than latter one half."
Now as if only has the Chinese standard is been desolate, in its camp and the non- telecommunication operation business joins.
