Global quality of service indicator

During the months of existence of the Velocimetro, it has generated a great base of information relative to the tests and users. Based on all this information this report has been done, containing the main usage statistics and study of the different technologies available on the market.

All this information is surveyable from different viewpoints, but it is necessary to express the results through an indicator of the quality of service, ie, a unique numerical data that represent the overall situation of the quality of speed in the Internet access. This factor is calculated as follows:


where the summation bears in mind each of the technologies [i].
Given that the speeds will be different for upload and download, in case of asymmetric technologies, this indicator is calculated for two-way transmission . This factor is an expression of the global average speed of all tests performed against the service of Velocimetro, regardless of the technology used by users.


The previous figure represents the values obtained for the global indicator of quality of service in the period of this report, from January until December in 2007.
