Device Maps are used to visualize End Devices locations.
By default, an Application may have too many devices to be displayed on the map. If this is the case a warning symbol will be displayed on the map refresh button indicating the user is zoomed out too far.
After zooming in the Warning icon is removed from the map refresh button. This warning icon will disappear as soon as the zoom level is appropriate.
The square markers represent the GPS coordinates for the devices on a map.
The map has a device statistics header that shows RSSI, SNR, PSR,and Data Rate collected from the previous day. Redundancy is the average number of Base Stations per Device. Each statistic can be selected to update the status color of the devices to match the statistic. For example, selecting the RSSI statistic will refresh the map and all devices will be colored by the RSSI value. The current value of a statistic is shown in the Information dialog shown by right-clicking a device marker.
Base Station Analysis
When Base Station Analysis is active, the Redundancy Statistic is replaced with a Location statistic. The Location statistic shows the average number of Devices heard by the target Base Station for the previous day.
When a Planning Map is active, an additional set of statistics including Entries and Path Quality is visible from the header. The Entries statistic shows the breakdown of Devices and Base Stations included on the Planning Map. The Path Quality statistic shows threshold groupings by Path Quality of all Devices on the Map.
The threshold values for the chart statistics are as follows:
|Data Rate||PSR||SNR||RSSI||Entries||Path Quality|
|DR 0||Above 85||Very Good SNR: > 1||Very Good RSSI: > -95||Device Count||Very Good Path Quality: > 75% and <= 100%|
|DR 1||50 to 85||Good SNR: >= -1.5 and <= 1||Good RSSI: > -105 and <= -95||Base Station Count||Good Path Quality: >50% and <= 75%|
|DR 3||25 to 50||Fair SNR: >= -4 and < -1.5||Fair RSSI: >= -115 and < -105||N/A||Fair Path Quality: > 25% and <= 50%|
|DR 4||Below 25||Poor SNR: < -4||Poor RSSI: < -115||N/A||Poor Path Quality: >= 0% and <= 25%|
The Devices shown on the map may be filtered to those matching a specific Tag, one or more Applications and one or more Contracts.
To apply Device filters to the map:
Click the button
Select the "Filter Devices" menu item
Update the Filter Devices dialog with the desired filters and click "Apply" to update the map to show only the Devices that match the applied filters.
Filtering Map Labels
Road and point of interest features and labels are displayed by default on the Map. These can be disabled for a cleaner Map appearance by unselecting the Labels checkbox under the Map control.
