The Automatic Site Prioritization (ASP) in Xirio is a calculation that allows, given a multi-transmitter study, to automatically select the best transmitters based on the criteria set by the user. This procedure consists in the iterative execution of administrative queries, which allow to discard the areas covered by the highest priority transmitters and to put the rest of the transmitters in order according to the areas still without service. It should be taken into account that the solution obtained through this procedure may not be the optimal one to cover the whole service area, but it is only a prioritization of the transmitters or sites of the network.

This functionality requires to have previously calculated the signal level result of the multi-transmitter study.

Selecting the corresponding option in the multi-transmitter coverage action panel will open the calculation configuration window:

For this calculation, several cartography layers can be selected, which must be of administrative type. This selection of layers will delimit the area of the calculation. The controls of each layer allow to configure it for prioritization according to these parameters:

•Magnitude. Depending on the type of administrative layer, the magnitudes that can be considered for the prioritization will be shown. Thus, for a layer containing surface and population data, the effect that each of these two magnitudes will have on the prioritization can be configured independently.

•Weight to be given to the magnitude for its weighting in the prioritization. A value of 0 means that this magnitude will not be considered in the process.

•Minimum and maximum values for the lowest and highest score. It can be configured so that these values are calculated automatically (from the minimum and maximum values per transmitter obtained in the calculation).

•Saturation value.

•Value for the reception threshold.

In addition to the selected administrative layers, the transmitters can also be configured, which can have a multiplicative or additive effect on the prioritization.

Below, in the transmitters prioritization, the weight that each transmitter will have in the process can be set using the "Priority" field. There is also the possibility of forcing a transmitter to always be included in the prioritization result, regardless of the score it may get in the process. In addition, since this calculation may involve a large number of transmitters, to facilitate this configuration, the possibility of exporting and importing these attributes by means of CSV files is offered.

Finally, for the presentation of calculation results, stations can be grouped at sector or site level.

RESULTS

After finishing the calculation, the following result tables will be generated:

•Transmitter prioritization. Report indicating the order of priority of the transmitters, the first one being the one that covers the most of the magnitudes (i.e. area, population, etc.) considered for the prioritization according to its weight. If the grouping by station was selected, the transmitters will be grouped in consecutive rows when they belong to the same site.

•Prioritized coverage contribution. Report where the same transmitter will be repeated as many times as entities (toponyms) it reaches with its coverage. The values of area and population covered refer to coverage provided by each transmitter and that was not already covered by other transmitters of higher priority.
