Anonymous users2024-02-08It is mainly reflected in the network. However, the network speed is dozens of times faster than the current GPRS. Since the current 3G standard in China is TD-SCDMA and the foreign system is WCDMA, for the time being, foreign 3G machines cannot enjoy 3G services in China.
There is news that WCDMA may be incorporated in the futureThe specifics are not yet known.

Anonymous users2024-02-06First, 3G actually refers to a wireless communication technology, we are currently using 2G, so what are the advantages of 3G over 2G, its advantage is that the data transmission speed is much faster (like the difference between our ordinary highways and highways, so, 3G is a wireless bridge communication technology to put it bluntly).
Second, the mobile phone is not suitable for 3G, because if the mobile phone wants to support 3G, it must have a 3G hardware module in the mobile phone, so if the mobile phone does not have a 3G module, then it does not support 3G.
Third, the current policy adopted by operators is to support 3G by changing mobile phones without changing numbers, so any number segment in the future will be a 3G number segment.
Third, the opening of 3G should start from the current basic situation of China's 3G, our country's 3G has 3 technologies, namely China Mobile's TD, China Telecom's CDMA2000, China Unicom's WCDMA, these three are not the same as the current 3G business development, and the business development is also relatively chaotic (maybe the above policy has, but the business hall below has not known this policy).
To give you some of the recent 3G business development of several major operators, at present, China Mobile has only carried out 3G services in Shanghai, Beijing, Tianjin and other blind Olympic cities, Guangzhou has also been carried out recently, and other places are estimated to be 6 or 7 months, but you can call 10086 for specific conditions.
China Unicom estimates that it will not release the 3G trial operation plan until World Telecommunications Day at the earliest, which also means that if you want to handle Unicom's 3G business, it will be at the end of May at the earliest.
China Telecom's CDMA2000 advertisements are full of envy, but it is only in trial operation in some cities such as Shanghai.
Fourth, as for the 3G charging standard, at present, in terms of mobile and telecom tariff standards, they are relatively high, and it is also an initial standard, and the tariff will definitely have to be adjusted after the 3G is officially operated together.
Fifth, not all smartphones can use 3G, it depends on whether the mobile phone has a 3G hardware module, because smart phones and 3G mobile phones are not the same concept, smart phones mainly refer to whether the system of the mobile phone is intelligent, and 3G is supported by hardware.
First of all. A 3G phone is just one more 3G module than a regular phone. Other features are exactly the same! >>>More
It's really good, a good article that lights up.
Theoretically, the only difference between 3G notebooks and non-3G notebooks is that they already have their own 3G Internet access modules and services. General notebooks can also add 3G Internet access modules and services to achieve 3G Internet access. However, the current 3G notebook is generally only a 10-inch small book, and the performance is not good.
What is a 3G License?
The license to operate a new generation of mobile communication systems that combine wireless communication with the Internet and other multi-level communications. >>>More
Tianyi, I have been online for more than a year, Tianyi 89** has been used for 3 months, I think it is still good. There is a point, to use a special EVDO CDMA2000 mode of 3G Internet mobile phone. Otherwise, the ordinary 139 130 can not be used because the frequency used is not the same. >>>More
