There are a lot of misunderstanding about this problem, has not been more understanding, but also can be used to express the language of people, so that more people understand, in order to achieve the community has a sober understanding of the problem, rather than due to the telecommunications and Internet, the nature of the problem forgotten. 1. is WiMAX low cost? This is a key issue and we have heard too many of these claims that it costs less. Why the cost is low, a base station can undertake dozens of kilometers of coverage, and can provide dozens of trillion transmission speed. Beijing can cover a few base stations, the base station is no more expensive than millions of, Beijing may be millions of or tens of millions of can build a network, the cost is not low. Most people listen to this saying, agree, of course, the cost is low, such a good technology why we do not need it? In fact, there are two problems in the face, a base station can do cover no corner? What about the buildings, basements, subways, elevators and all kinds of special places? These places still want to use the technology of class repeater, carry on the supplementary of dead angle, these small base station still want to install in different place, need and building, community owner to talk, need to use optical cable to connect up, need to cut the road. These are costs that may cost far more than a base station. These costs may be a lot of WiMAX people forget, or know deliberately do not say. Another problem is a base station covering dozens of km, this range of hundreds of thousands of or more users, a base station can open how many channels, and how many users support? If really alone 100 trillion speed may be just a few users, sharing that everyone went up to die, and what use value. Of course, this problem is not to be solved, more base stations, to carry out diversion. This has appeared such a problem, since the number of base stations, the same to go to the network optimization and improvement. These costs are the same as the whole construction costs. How can we say WiMAX is a low-cost technology? 2. is WiMAX used? In my opinion, WiMAX cost is not low, it is useless. I don't see much of it, 3G is not a good thing, to rely on 3G to solve high-speed data transmission, can be guaranteed anywhere, that is a lie, now the technology is still not, such as Zhongguancun, we all need wireless data transmission, by 3G can not build a base station 100 meters. Here it needs other technology to add, I think WiMAX is a good thing, 3G can be solved anytime and anywhere, WiMAX can be in a specific area to provide a good speed network. It's like I'm using WiFi at home to do a high speed wireless Internet at home, outside with the CDMA online card, although the speed is not satisfactory, at home I was never used, but, after all, there is better than no, simply look at a Web page, email or no problem, want to see network TV or go home to see it. So WiMAX and 3G is a fusion of products, not who replace the problem. 3. 3G is not good at speed. It's notTo utter nonsense, unimpressed is a process of development and evolution, in addition to the original version, as well as HSDPA, HSUPA, the future of LTE I have seen its demo transmission speed of 40 trillion, of course, when the telecommunications equipment manufacturers do not try to say this, not without, but its original equipment has not been sold, The back of LTE is still in the process of research, of course, will not vigorously publicize. WiMAX is different, it hopes to be able to take a piece from the traditional network of telecommunications, of course, do not hesitate to publicize its benefits, and the propaganda process is somewhat misleading. 4. WiMAX and 3G will each account for how many markets? I think any expert dares to say this share, he must be a lip-talk, this market by technology development, policy, user experience, price, operator's attitude even we did not think of the external influence, there are markets, how big market, we do not know. He must have cheated you if he knew.
