Five advantages of WCDMA5
Advantages 1, WCDMA has abundant terminal advantages.
To enjoy 3G services, the networks of the three operators need different terminals, so it is impossible for a mobile phone to be universal. Then, it is very important to choose a terminal with rich 3G services. What are the prospects of three 3G terminal types?
Let's talk about CDMA first. Why is it difficult at the beginning of CDMA development? It is because there are few types of CDMA terminals and the price is expensive. This is all caused by Qualcomm. Qualcomm has a CDMA patent, and charges a high patent fee to the terminal manufacturers that produce CDMA, which makes the terminal manufacturers of CDMA mobile phones have to pass on the cost to users, making the price of CDMA mobile phones high, thus restricting the development of CDMA services. Now CDMA is married to Telecom and renamed as "Tianyi" mobile phone, but the terminal restriction problem has not been solved, even in the future CDMA 2000, it is still difficult to change.
Let's talk about TD-SCDMA terminals of mobile companies, and the situation may be even worse! TD is a new technical system. At present, there are only about 30 terminals supported by the contract. If you find that this 3G service is only supported by 30 mobile phones, won't you feel too monotonous? Due to the lack of mobile phone styles and unclear user groups, manufacturers dare not mass-produce easily, and the price of TD mobile phone terminals is bound to remain high. Recently, in order to develop TD terminals, China Mobile had to introduce a policy to subsidize tens of billions of yuan for mobile terminals. However, with the intensification of full-service competition, China Unicom challenged China Mobile in the north and telecom companies attacked China Mobile in the south. Can China Mobile continue to maintain high profits? How long can this way of subsidizing TD terminals by high profits last? Its prospects are not optimistic.
Finally, look at our WCDMA. As of February this year, there are 258 networks operating WCDMA in more than 100 countries, with 320 million users and a global market share of 77%. There are more than 1000 WCDMA terminals in the world, including 450 HSPA terminals supporting 3.5G The appearance, performance and types of WCDMA terminals have been significantly improved and enriched, while the price is still falling. Major manufacturers such as Nokia and Sony Ericsson are mainly engaged in WCDMA mobile phones, and Apple, the world's largest mobile phone terminal, will also launch 3G iPhone phones supporting WCDMA standards.
At present, there are a large number of WCDMA parallel mobile phone terminals in China communication market. Although most of these end users are even 2G users of mobile companies, who can say that once they are on WCDMA, these users will not switch to the new Unicom and directly use the 3G services of the new Unicom? Therefore, WCDMA, with its mature industrial chain, abundant mobile terminals and good cost performance, will promote the faster development of WCDMA services. So how will users choose, is it not clear?
Advantage 2: WCDMA has large bandwidth and fast speed!
In addition to terminal advantages, WCDMA also has technical advantages! What do we need 3G for? Video phone, mobile TV, mobile Internet ... This requires high bandwidth and speed of wireless transmission. So who is the fastest of the three 3G companies? It's WCDMA
At present, CDMA 2000 of telecom adopts EV-DO system, TD-SCDMA of mobile adopts TD-HSDPA system, and our WCDMA adopts HSPA system. The standard of mobile and telecom is 3G, while that of Unicom is 3.5G From the three 3G technologies, WCDMA has the widest data transmission bandwidth, the fastest speed and obvious advantages. 3G services such as videophone, mobile Internet and mobile TV based on WCDMA will be smoother, and it can also support more users to use it smoothly in the same community.
Advantage three. New Unicom's 3G is rich in content, and you can see everything.
With the terminal and speed, what are we going to do with it? Watching movies, videos and information ... In this respect, the new Unicom still has obvious advantages.
The new Unicom is a strong combination of the original Unicom and Netcom. The Internet resources of former Netcom are very rich, which can be used on the mobile Internet. At present, the new Unicom headquarters is developing and building a platform for large code stream and small code stream. After building this platform, mobile phones can directly access the rich video resources and other information resources on the Internet, without accessing the video resources and SP specifically for mobile services.
On the other hand, although a large operator has many users in the 2G mobile phone market, it will be difficult to provide its 3G users with mobile phone resources comparable to the current online resources for a long time due to its lack of Internet resources.
Advantage 4: WCDMA has truly achieved global roaming and can travel whenever it wants.
WCDMA 3G system has networks in more than 0/00 countries around the world, with 258 networks and 320 million users, accounting for 77% of the global market share, while CDMA 2000 has networks in 62 countries, with 95 million users, accounting for 23% of the global market share. TD-CDMA has no network abroad. WCDMA is the best choice for domestic business customers who often go abroad and want to roam the world. In addition, with the strengthening of China's strength and more frequent exchanges with the world, roaming WCDMA international users will become more and more abundant, providing a valuable income for the new Unicom!
Advantage five. WCDMA technology is mature, and upgrading to 4G is just around the corner.
At the beginning, everyone used 3G new services well, but with more and more users using 3G, the current 3G network is gradually insufficient. Its main performance is that the network is crowded, users feel that the data download is slow, and the video is no longer smooth. According to the current 3G technology system, if the business develops normally, the bandwidth will be obviously insufficient in a year or so. At this time, it is necessary to upgrade the software version of the corresponding local equipment, and greatly increase the bandwidth, speed and application of wireless transmission without adding or adding a little hardware. This is also the saying that upgrading from 3G to 3.5G or even 4G..
The difficulty of technological upgrading under the three systems is different. TD-SCDMA, as a self-produced 3G system, its technical core is mainly controlled by Datang Telecom, and there is no large-scale application in the world at present. The next technology upgrade route, whether from the perspective of technology developers or experimental users, is not large in scale. The future technology upgrade route can be described as "crossing the river by feeling the stones", and the prospects are unpredictable. CDMA 2000 is a patent in Qualcomm. UMB technology led by Qualcomm can be said to be the highlight technology of CDMA in 3G upgrade technology. However, due to the technology monopoly and closure in Qualcomm, UMB technology has not been widely recognized by the market, nor has it formed a perfect industrial chain and scale. At present, the global investment in CDMA has fallen sharply. Alcatel, Lucent, Nortel Networks and Motorola, the world's largest CDMA equipment vendors, have all cut their CDMA departments. Finally, Qualcomm announced that it would stop developing UMB technology. This once again confirms the law that the industrial chain of communication industry determines the success or failure of advanced technology. On the other hand, WCDMA is the mainstream 3G technical standard in the world, covering more than 65,438+000 countries, with 258 networks and 320 million foreign users, with a global market share of 77%. It has gained obvious advantages in the competition with another 3G standard CDMA2000 series. Especially in the subsequent evolution to 4G, WCDMA standard is the most mature at present, and it has won the support of most operators in the world with a clear technical evolution route. At present, HSPA technology with logo 3.5G can be deployed in large and medium-sized cities in China in June and July, and HSPA+ technology with logo 4G has also started to be built in Australia, Singapore and other places, with a speed of 2 1Mbps. We will upgrade to 4G soon. This fully embodies the principle of global integration and "everyone gathers firewood and the flame is high".
