HOW TO USE
Select an element on the treeview, then click on Load Elements on the MapChart menu.
MapChart home screen will be loaded.
The interface shows:

Frequencies
It is possible to select all frequencies or a specific one. Just click on Frequencies to see the options.
Function
Click on the Function list to choose between PRACH, time advance, or handover frequency – depending on the technology.
Use the buttons + and – to zooming the map in and out.
You can also use the mouse scroll.

Click on the Arrow on the bottom left of the map to see Element Properties.
NOTE: Click on the buttons LAC , RNC , and ScrCode to highlight the cells that belong to the same group.
By clicking on the ScrCode button, the cells with the same scrambling code of the selected cell, or the ScrCode number – 1 or + 1, will be highlighted on the map.
Base Layers
Click on the Layers icon on the map top-right to see layers options.

Active the Select all Sector option to select all cells when clicking on a sector.
Click on the Cell Text option to choose the information that is displayed. The list includes number or sector, id, name, BCCH or SCR code, and LAC.
After configuring the options, click on OK to save the settings.
Kpi Options
Click on the Execute KPIs option to define if MapChart will calculate KPIs for all loaded elements or only for the selected cells.
Active the Track re-homed option to keep track of re-homed cells during the calculation.

Define each technology’s cell size and color by clicking on the Color menu and dragging the Size slider.
The scale varies from the smallest representation (on the left) to the largest (on the right).
Others
Activate the Filter Hours to define an hour range to collect data. After clicking the button, write the beginning and end times.
Activate Strict to calculate the values considering all measurements between the time interval.
LAC / RNC / ScrCode
Click on the Arrow on the bottom left of the map to see Element Properties. Click on the LAC button to highlight all the cells that belong to the same LAC.
This behavior is typical of the RNC and ScrCode buttons.
Neighbors
Select a cell on the map. Click on the Function list to choose the kind of adjacency you want to plot. The adjacency lines leaving of the select cell (source) to the target cells.
NOTE: The color of the lines is related to the done scale shows on the left. The thickness of the lines is associated with the attempt number: the thicker, the more attempts.
Below the map is the Neighbors’ information.
1- Click to select the first ten rows in the table and also highlight these cells on the map.
2- Click to show on the table just the selected lines. (Click above each table line to select it).
3- Click on the Settings icon to set the Handover Lines (Outgoing or Incoming) and the Line Text (Attempts, Success, Distance, or all).
4- Search by some specific cell.
5- The first column brigs the adjacency ID. (N/D means Not Declared adjacency).
6- This column informs the source cell.
7- The target cell is also shown on the table.
8- The percentage of success outgoing to the selected cell is presented in this column.
9- This column brigs the attempts of HO outgoing to the selected cell.
10- The percentage of success incoming to the selected cell is seen here.
11- This column informs the attempts of HO incoming to the selected cell.
Attempts per distance
Select a cell on the map. Click on the Function list and select PRACH or Timing Advance, depending on the technology. It is possible to plot how many PRACH you want.
NOTE: The stronger color means the range has more attempts.
Below the map, are shown:
1- The propagation delay chart.
2- The values are shown in the ranges. (Percent, Distance, Absolute, All, None).
3- Click to contour the lines separating the ranges.
4- Click to remove the plot.
5- The name of the selected cell.
6- Date from.
7- Date to.
8- The PRACH Delay Range used.
9- The color of the plotted PRACH. Click to choose another color.
Transmission
MapChart displays the links between all the network layers, including the RAN and CORE elements.
To begin, select an element on the treeview. Then, click on the Load Option on the MapChart menu.
A map will be loaded with the region’s elements and their links.
1- On the screen left side are the KPI options. Users can plot the KPIs on the map by color and/or size.
2- The map is shown on the right side.
NOTE: To know more about running a KPI or navigating through the map, read the Functions Description section.
