The European and American 3g standards' smooth migration is fraud?
-Chinabyte
The smooth transition is fraud. WCDMA and CDMA2000 basic same (Reporter Wan Li river Beijing on 10th reports)
Beijing posts and telecommunications university Professor Li today indicates in here: " Basic does not have the smooth
transition, the smooth transition is the European and American big financial group for seizes the 3g market the clever
trick, completely is deceives people."
Information industry department telecommunication science and technology research institute vice-chief Li Shi He also
the language is startled in afterwards the lecture the person: " WCDMA and the CDMA2000 basic technology is same, its
difference completely is artificial (because intellectual property rights reason) formulates." They are express this time
opinion at the Chinese project courtyard eighth project science and technology discussion forum, this time converged
take " the third generation mobile communication " as the subject discussion forum to include all quarters public figure
and so on government official, operation business, scholar expert, equipment factory representative, Chinese project
courtyard Vice-President the Zhu peak, Chinese wireless correspondence standard research group President Cao Shu
Min, the country 863 planned 3g research development item overall group Leader You Xiao Hu and so on 8 cores public
figures makes the subject lecture. The lecture starts from the morning, always in has the foreword carries on, but speech
starts from Li Dao Ben, the atmosphere had the change, is once again proposed in the 3g domain nation correspondence
standard and the European and American standard this sensitive topic, the domestic several names expert the WCDMA
standard which initiated to USA'S CDMA2000 and Europe proposes the question. From GSM (2g) - GPRS - Edge -
WCDMA (3g) and IS95 (2g) - C$dMA20001x - C$dMA20003x (3g) continuously is the smooth transition which in the
European and American standard elaborates, also namely with does not construct the network in addition in the transient
process or only must construct the partial network, like this may save one astronomical figures the expenditure, promotes
a 3g quicker popularization. This view continuously by various media quotation, but today encountered the Li Dao Ben
denial. Professor Li detailedly explained extant 3g all sorts of flaws, (ITU) proposed from 3g in 1996 after the
international electricity association, already nearly 5 years time. But as a result of the huge benefit, 3g already turned take
the standard as the core stage politics and the economical struggle, thus limited the technical innovation, up to does not
have one full test to the now the 3g system. Li points out, IMT-2000 limited with the Internet and its the correlation
service cooperation, ill to take IP as the foundation Internet demand, moreover this standing operating procedure
frequency spectrum will satisfy the future does not move the Internet the request, the frequency spectrum use factor is
low. The existence overcomes receiving and dispatching with difficulty anti-interferrence, the cost higher all is the
European and American standard shortcoming. Regarding European system GSM-WCDMA and US standard IS - 95 -
CDMA2000, Li said: " Their technology is backward, still was 2g or the 2.5g technology." Regarding " the European and
American big powers ", the Li ShiHe also has the speech says, he think the European and American standard not too big
difference, the basic technology is same, inside the 3g technology involves the patent are very many, Europe in order to
strive for the future over a thousand hundred million 3g market, certainly also will have to register some own patents, but
this left behind the hidden danger. Korea just discussed the WCDMA authorization production, needed more than 200
companies to hand over the patent expense to the world in, accounted for its sales volume 18%. " What concept 18%
was the, the profit one most probably all does not have." The Li ShiHe emphatically emphasizes. The under equipment
manufacturer and the expert one excitedly gets up, the intense request government enlarges in abundance to our country
3g basic research support. Li Shi He also said one which frightened, Europe's 3g operation business has very many, but
their standard mutually disturbed under the multi- operations business environment, they needed the certain protection
band width, probably about 5MHZ, but this was their band width one half. If is only left over the 5MHZ useful band
width, that has not distinguished with 2g. Is worth paying attention, attending academician and the government official has
not certainly joined in this big discussion, in is all static static listens attentively. But two Professor Li all have the home
company background, Li Dao Ben is Lian Yu(LinkAir) corresponds company's chief scientist, LAS which Lian Yu
proposes? CDMA is considered is the 4g standard is popular candidate, moreover can the very good solution existing 3g
question; Li Shi He is big Vice-President Tang telecommunication Academia Sinica's, DaTang telecommunication TD?
SCDMA is and WCDMA and the CDMA2000 compound nation correspondence standard.
