It is understood that Huawei in China also owns 7% of WCDMA core patented technology. Compared with other standards, WCDMA has the following advantages:
1, through the development of 10 for more than six years and its commercialization, has become the most mature 3G technology in the world.
2. Fast Internet access. At present, the theoretical peak download speed of the HSUPA network (WCDMA Advanced Edition) deployed in Shanghai is 14.4M/s, and the upload speed is 6.8m/s. The actual application has not been tried, but it is estimated that it should be above1m.. Because the shrinkage of the European standard should not be as serious as TD. Even if it is only 200k, it has already caught up with the speed of general home broadband.
3. High signal coverage. At present, the smallest WCDMA base station can directly hit the wall, about the size of a wall lamp. In developed countries in Europe and America, many are home base stations, which are the same equipment as wireless routers at home. They are very small and light, and they have the functions of wireless Internet access and radiating telephone signals. Speaking of building base stations, according to the current situation in China, someone once praised it as follows: "It is not enough for residents to stop operators from building base stations. This kind of thing only happens in high-quality communities in highly developed areas such as Beijing, Shanghai and Shenzhen. If you build a base station with a length of about 2 meters and a weight of 500 kilograms like TD, people will object. Then directly hang a WCDMA base station with the size of a light box on the street lamp in the community, saying that it can improve the quality of telephone calls and has little radiation. Will anyone object? In the long run, China's WCDMA coverage and signal will be the best in 3G. "
4. The network quality is good. Due to good coverage, WCDMA can ensure that users can enjoy 3G services at will in the main city. This is not important when the user is on a business trip or driving away from the 3G coverage area. Mobile phones can smoothly transition to GSM network, just like the current G network transitions to E network. Because WCDMA itself is an upgraded version of GSM, there will be no problems of dropped calls and network switching.
5. Abundant mobile terminals. At present, there are more than 3,000 kinds of WCDMA mobile phones for consumers to choose from, and the prices are cheaper than the other two. At present, the star mobile phones in the world, such as iphone, Google G 1, Samsung i968e, Nokia E6 1 and Dopod P860, are all WCDMA mobile phones. Not to mention low-end products, Nokia, Samsung, MOTO, LG and other low-end WCDMA products are even more dazzling.
