iewpoint data transport is not supposed to interfere with the quality of the system itself. This is another opportunity to make the same aforementioned remark that when talking about transmission optimisation and 3G optimisation different things are meant. This also clarifies why it is easy to get confused when the optimising interface between the ME and BTS and optimising transmission are mentioned close to each other. The fundamental difference between these two optimisation challenges is that the 3G network does not make any perfection assumptions about the interface between the ME and BTS. Rather it assumes that the interface is a long way from perfect. That is a very fair assumption since between the ME and BTS the connection is made in three-dimensional free space and the connection relies on reflections and interferences of electromagnetic fields. It is clear that the whole system has to focus on performing well in that complex environment and there can be many parameters to tune. However, the nature of transmission is 'borrowed'. Transmission is something that is needed but where fair assumption is that it must be able to provide such a level of service that it is transparent to the 3G network. It does not need to be 'own' network as long as it can provide needed services. This is also a fair assumption since the transmission network is usually point-to-point and has interference protection. It could be described as having fewer dimensions. It can also be said that due to this weak interlinkage between these systems, looking at 3G system related parameters does not provide any transmission optimisation solution. This can be said even though the meaning of optimisation has not yet even been defined. Definition of Optimisation Optimisation, on the other hand, is generally a synonym to improvement, but there are different approaches that can be taken. A common nominator to these approaches is that they all try to achive the same goal, i.e. to increase the profit of the cellular operator. In Western capitalis
