5 Conclusion

Before starting writing my conclusion, I need to show my frustrated mood at this moment. When I was still reading a lot of materials and information about my topic WiMAX, when I was still expecting to finish my blog with full of a lot of knowledge in this area, when I was thinking what is the grade I may obtain in this course, just one email shaked me today. From the email I was noticed that I already got the grade for this course and the appraisal date is 9th July which means two weeks ago, the blog had been evaluated when I only finished 30-40% of my work. It was too surprise for me because without any sign, I failed the course. Then I tried to review and recheck what's wrong, I asked my friend who also took this course and the result was that the maybe I missed the deadline. Deadline? I am keeping asking myself why I don't know there is a deadline for this course, even the deadline itself. And by now, I still don't know why I don't know. Maybe I have not been informed? Or I did not notice the professor said something about the deadline? Whatever, I must ask myself why I didn't make sure the deadline issue. This may be my mistake, a unforgettable and funny mistake. There is no if after things happen, but I still want to suppose that if I know the deadline, I will, of course, keep it in mind and finish it ontime, or maybe discuss with teacher to extend it for a few weeks. But I did nothing. Is it a joke to me which make me fail on the last course like this and actually I never failed before? Hopefully it's not. The only thing I can do currently is to discuss with the professor and try to explan what happen. I hope he can understand me, I hope! Because I think I will eventually touch the sky one day. Anyway, in such a upset situation, I am holdding my tear to complete the conclusion finally.

Unlike the great situation for WiMAX in the past years, WiMAX in the year 2008 goes not well. Especially in developed countries, some important companies such as Clearwire, Sprint Nextel, Intel, Nokia slower their development in WiMAX. Considering many other competing technology and standard including HSPA, HiperMAN, LTE, etc., in the near future, WiMAX has to face more challenges in the crucial and cruel competition in wireless field. The worldwide trend of WiMAX is complicated, as I mentioned before, different regions and countries shows different situations and also even in the same countries, the situations will keep changing through time dimension. Prediction is possible but not accurate.

Despite the unclear future, WiMAX still has a large number of technology and market advantages. In fact, a successful Broadband Wireless Access business will depend on a stable and comprehensive ecosystem. The three key elements to building the WiMAX ecosystem are good standards, widely available devices and cross-industry cooperation. Standardization is essential to enable the widespread adoption of any technology. It was true for WiFi and it will be true for WiMAX. While the IEEE has been producing the standards, theWiMAX Forum is encouraging wide spread take up of WiMAX byestablishing and promoting the WiMAX certification profiles. The Forum undertakes network architecture and related profile definitions, testing and certification of products against profiles and standards to ensure interoperability of equipment from different vendors. Mobile WiMAX supports true mobility and with low cost in products. The next consideration is achieving widespread availability of interoperable devices that will evolve to meet the differing and growing needs of consumers and business users. The evolution of Mobile WiMAX and the availability of handheld WiMAX devices will drive the market to more advanced applications using voice, multimedia and data for both consumers and businesses. Thirdly, A wide selection of organizations have been involved with WiMAX for several years and the level of cooperation has been as good as that seen during the development of other wireless ecosystems. Cooperative partnerships have been formed to advance the development of crucial elements of the ecosystem. The expertise needed to evolve the ecosystem is already well developed and in place. Cooperation extends across the industry, involving major groups that are investing in the development of chipsets, devices and other fundamental components, to smaller players providing the basic building blocks such as antennas and other infrastructure components. This deeply vested interest shows that WiMAX has the coordinated backing of the industry to ensure success.

The advantages which have been discussed before shows that WiMAX is a good technology to be the next generation wireless standard. Even in ecosystem degree, it is also acceptable and advanced. However, there are still many problems for WiMAX to face including property right problem, frequency problem, and also it's hard to compete against other mature technology using in developed countries, especially in 4G market competition. Compare with GSM, UMTS or HSPA network, it's still far away for WiMAX to replace or compete against them which are the traditional leader in wireless access network. It's a good option for WiMAX to change its target to small market and transition market such as developing countries markets because at this moment, WiMAX has large advantage in those countries. That's why many developing countries have steady increasing trend. In total, no one knows how far WiMAX can reach, but I truly believe that WiMAX will have its stable market in the future, at least in Asia, while the road will be not that easy.
