With the arrival of telecommunication day on May 17, since the beginning of 2009, more and more netizens have paid attention to 3G. At present, there are three main domestic 3G networks: TD-SCDMA of China Mobile, WCDMA of China Unicom and CDMA2000 of China Telecom.What kind of network system can satisfy consumers? I believe many consumers are hard to judge.And as the most important component of 3G Network - handheld terminals (mobile phones), I believe it is also the focus of many consumers.At present, mobile TD-SCDMA mobile phone models in China are popping up frequently, among which there are many highlights, such as Lenovo Ophone, Nokia, Doppler Magic, etc. Here let the author join you to understand several powerful models under the TD-SCDMA network system.Nokia TD-SCDMA Mobile Phone Model: Pending Reference Quote: Not yet on the market With the rapid development of 3G network in China and many mobile phone manufacturers follow up, Nokia finally launched TD-SCDMA mobile phone, this Nokia's first TD-SCDMA test mobile phone model is still not availableYes, but from the keyboard and menu design, we can see that it does not use the S60 operating system, but is equipped with the S40 system, which has a straight body style similar to the early hot 6300.The picture shows: Although Nokia TD-SCDMA mobile phone does not have more parameter data, we can see from the exposure picture that this Nokia TD-SCDMA mobile phone must be equipped with a QVGA resolution screen and a 3.2 million pixel camera, while the functions of standard MP3 and Bluetooth will not be missing, and it will not be inferior to previous S40 mobile phones in function.The picture shows: Nokia TD-SCDMA mobile phone This Nokia TD mobile phone's biggest selling point is to provide support for TD-HSDPA technology, the biggest feature is that the technology is considered as the next step in the evolution of TD network, can also be applied toWCDMA and TD-SCDMA are two different kinds of network support, which can support asymmetric data services very well, that is, users of this Nokia mobile phone can use the 3G network even when roaming around the world.And its front camera also confirms the identity of its 3G mobile phone.Picture: Nokia TD-SCDMA mobile phone from the current exposure of the test situation, through the Nokia TD mobile phone connection network, its download speed can be stable at about 1.3Mbps, but according to some domestic media reports, Nokia official has confirmed that it will cooperate with operator China Mobile to produce its first TD-SCDMA S60 mobile phone in the second half of this day, you should look forward to it.Wait.The picture shows: The last interesting thing about Nokia TD-SCDMA mobile phone is that industry insiders have pointed out that the exposed Nokia TD phone is actually a TD test phone that appeared last summer, but with the collapse of Nokia's TD chip manufacturer & ldquo; Kaiming & rdquo;, which owns part of the shares, this model has been cancelled.Although there is no official information about the identity of Nokia's TD test phone, there is no doubt that Nokia will introduce a lost TD phone, and we believe that you will also want to have more mobile phones to choose from under the TD system.
