Implementation and Integration aspects in UMTS

Research studies aiming to improve the overall performance of multiple access techniques such as WCDMA or TDCDMA have provided interesting and applicable methods. However, these results may not necessarily be part of the first UTRA commercial systems in the next 2 years. Thus, it will be some time before techniques such as Software Radio, Adaptive Antennas, and Multi-user Detection enhance capacity, coverage and increase system stability.

Implementation and integration appear as key limitations to bring these advanced techniques into operating systems or near future11 exploitable networks. Processing power demands for example, do not allow rapid implementation of the above methods. Furthermore, integrating such techniques into smaller components is a great challenge. This means, that while less optimum supporting techniques like system on a chip, maximizing power consumption, or operating at very low power come into place; the aforementioned improvements will remain academic.

At present, while UMTS frequency licensing becomes big business for governments, operators seem to have fall into the spin of supremacy and consolidation for market share and have somehow forgotten the timeliness of technology. Manufacturers are finding themselves in a race to supply plain vanilla solutions and are incapable of implementing true breakthroughs in multiple access or radio-access techniques.

Thus, it seems reasonable to think that it may be to the benefit of industry as a whole and governments themselves to concentrate on putting more resources into the realization of new communications technologies than just coping with spectrum allocation and acquisition to offer services with higher transmission rates. Such an approach will make UMTS a clear platform for advanced technology from the start and not just one more alternative to provide new mobile applications.

Dear student,
I like what you have been doing so far. But please tell/explain me more about the need for standards in the different (technical/market)elements you have selected thusfar. Will standardisation bring a solution? Or even better what is your problem you want to address in your blog?
