Cellular Clarity
Overview
This chart shows the signal strength (the RSSI values recorded) for the cellular line over time. It also shows changes in cell tower ID, network and radio technology. The chart is only available for lines which have been set up as Cellular Clarity by an admin user.

Sidebar options and colour coding
Sidebar
- Click to reset all sidebar controls to their default value, appears faded if defaults currently in use
- Average
- Shows the average of all values received for each time period.
- Min/Max
- Available for week and month views, this draws a vertical gradient bar for the minimum and maximum values recorded for the time period.
Note: When signal strength is lost, Highlight shows this as a red blip at -120 dBm. Whilst there is no signal strength, there is also no information on cell tower ID, network or radio technology so Highlight registers these values as 0 or null. Changes to null values are not shown as blips - only changes to genuine values are shown.
- Tower
- Shows blips for changes in the cell tower ID, unchecking removes the line and any blips.
Cradlepoint: Tower changes are not reported in Highlight as the data is not provided by the device - Network
- Shows blips for changes in the network - for example Vodafone to O2, unchecking removes the line and any blips.
- Radio Tech
- Shows blips for changes in the radio technology - for example LTE to Wcdma, unchecking removes the line and any blips.
- If you click, hold and drag across the chart to zoom in then this button appears in the top right of the chart - click to revert to the full time period. See GIF in separate section on Zoom options below.

Cellular Signal Strength description

- For day view only, download the information to a CSV file (see sample CSV image below).
- Vertical axis
- Shows fixed values from -30 dBm to -120 dBm. The gradient on the right indicates "Excellent" values are green and near -30 whilst poor values show in red and are closer to -120. Hover on the chart to see exact values. Note: any values outside this range typically indicate no reading so these are mapped to -120.
- -90 dBm
- The threshold is shown as a horizontal purple line on the chart with the actual threshold value on the far right. If configured, a health alert can be sent when the signal strength drops below the threshold.
- Horizontal axis
- Adjusts according to the selected time period to show hours in day view and days in week and month views; redraws if the time zone is changed at the top right of the Details page.

Highlight displays the average recorded value for each signal strength data point in the time period:
- Day
- Shows multiple data points per hour (one for each polling period, usually five minutes)
- Week
- Shows 24 data points per day (every hour), Average for each hour is shown along with Min/Max values if checked
- Month
- Shows 6 data points per day (every 4 hours), Average for each period is shown along with Min/Max values if checked


From week or month view: clicking any data point jumps to the selected day view. See GIF in separate section on Zoom options below.
Zoom options
There are two methods to zoom in on charts: drag and click. All new style charts on the details page are synchronised so they zoom in and out together or the whole page jumps to a date on click.
