    Network: Coverage Trails Report

    The Coverage Trail report graphs gateway positions as a continuous line (trail) on the map. The trail color indicates the WAN connectivity state of the gateways (a legend is shown below the map).

    This report is best used for a single gateway over a smaller time period (e.g. one gateway trip) where the same location is not visited repeatedly. For cases involving additional gateways, larger time periods or repeat visits consider using the Coverage Map report instead.

    The map displays various gateway events including the trip start and trip stop points, and WAN link events. Small, medium and large green circles indicate where gateways stopped (the larger circle indicates a longer stop time). Black circles indicate where GPS signal was lost (often due to underground parking). Blue triangle markers provide location information.

    Note: The Coverage Trails report is supported for ALEOS devices in AMM 2.16 and above.

    In AMM 2.17.1 and above, a signal strength overlay function is available. The overlay can be toggled on and off and shows the recorded signal strength over the trail. The signal strength can be shown using one of the following parameters: RSSI, RSRP, RSRQ, SINR.

    After selecting a signal strength type, the signal strength data will be shown along the trails. A legend is displayed at the top right hand corner to indicate visualized signal strength colour.

    Signal Strength Level RSSI Range RSRP Range RSRQ Range SINR Range
    5 ≥ -78dBm ≥ -85dBm ≥ -4dB ≥ 13dB
    4 ≥ -87dBm & ≤ -79dBm ≥ -95dBm & ≤ -86dBm ≥ -9dB & ≤ -5dB ≥ 5dB & ≤ 12dB
    3 ≥ -93dBm & ≤ -88dBm ≥ -105dBm & ≤ -96dBm ≥ -12dB & ≤ -10dB ≥ 1dB & ≤ 4dB
    2 ≥ -102dBm & ≤ -94dBm ≥ -115dBm & ≤ -106dBm ≥ -15dB & ≤ -13dB ≥ -3dB & ≤ 0dB
    1 ≥ -109dBm & ≤ -103dBm ≥ -124dBm & ≤ -116dBm ≥ -20dB & ≤ -16dB ≥ -20dB & ≤ -4dB
    0 ≤ -110dBm ≤ -125dBm ≤ -21dB ≤ -21dB

    Click on any part of the trail or on the markers to open a pop-up that provides additional information.

    Signal strength events can be displayed by selecting the Events link in the pop-up.

    If an attempt is made to run this report with more than 10 gateways, the following message will be displayed, at which point 10 or fewer gateways will need to be selected before attempting to run the report again:

    Message indicating that too many gateways are selected for the report. Close the popup and ensure that 10 or less are selected.

    Basic Configuration Fields

    • Gateway(s)*: by default this is set to the gateway(s) selected in the gateway tree. Enter the name(s) manually to modify this field. Click on Filter to open the subfilter options.
    • Report time range*: use the drop-down menu to select from Previous Months, Previous Weeks, Previous Days or Range. Enter the numeric value in the field. When Range is selected, use the calendar pop-up to select the dates. Alternatively, enter the date and time manually (yyyy/mm/dd hh:mm).
    • Limit to map area*: select Not Limited to include data from any geographic location. Select Manually defined area to create a temporary zone for the analysis – only data from inside this zone will be included in the report. Select One or more zones to limit the analysis to one or more predefined zones (see the AMM Operation and Configuration guide for more information about zones).
    • Exclusion Zones: allows the report to exclude data from one or more predefined zones (see the AMM Operation and Configuration guide for more information about zones). Leave this option checked (default setting) to include data from any geographic location. Uncheck this option to specify zones to exclude data from.
    • Limit to network types: runs the report for a certain type of network. Click in the field to select the network type.
    • Show friendly names if available: when enabled, shows WAN link names in the report if they have been set in the gateway’s configuration.
    • Output Format: select HTML to generate the report in the browser window. Select Excel to display the generated report in Microsoft Excel. Note that the Excel option only works for reports which produce data in a table format.
    • Save for later or schedule a run time: enable to create reports that can be saved for future use. See Saving and Scheduling a Report for a Later Run Time for more information.

    Advanced Configuration Fields

    • Max bootup time*: enter the amount of time (0 to 1800 seconds) to allow the gateway to boot before reporting CALLDOWN. The default is 180.
    • Max time between events*: enter the amount of time (0 to 86400 seconds) to allow between gateway events before considering the unit non-responsive. The default is 3600.
    • Map Resolution: defines the size of colored “blocks” presented in a map, which are used to present the coverage trails. The default resolution is auto.
    • Active link colors: click on each link to change the default color (use the color picker).
    • Short stop*: vehicle stops are shown with small sized green circles if they have been stopped for at least this many minutes (up to the medium stop value). Default is 10.
    • Medium stop*: vehicle stops are shown with medium sized green circles if they have been stopped for at least this many minutes (up to the long stop value). Default is 30.
    • Long stop*: vehicle stops are shown with large sized green circles if they have been stopped for at least this many minutes. Default is 60.
    • Show direction every 5 positions: enable this checkbox to show vehicle direction every 5 GPS location reports. Default is OFF.
    • Show trails where gateways are booting: enable this checkbox to include times and locations where the gateway was booting up in the coverage trails. Default is OFF.
