From version v1.24, GPS Heatmap HTML files are supported for Spectrum Analyzer mode.

The Heatmap is a visual tool that represents radio frequency (RF) signal strength measurements over time and geographic location. It uses a color gradient (typically from cool colors like blue to warm colors like red) to indicate signal intensity. This allows you to quickly identify areas of strong signal (good coverage) and weak signal (poor coverage or interference).

Map Adjustments Panel

Radius: Adjust the radius of the color data points on the map. A higher value makes the heatmap colors appear softer and more blended, which can help visualize general coverage trends rather than individual, sharp data points.

Min (dBm) / Max (dBm): These values define the range of the color scale. Any signal weaker than defiend Min dBm value will be shown as the minimum color (e.g., dark blue), and any signal stronger than Max dBm value will be shown as the maximum color (e.g., red). Signals within this range are represented by a gradient. You can often adjust these to focus on a specific signal strength range of interest.

Auto Set Amplitude: Automatically analyzes the current data set and adjusts the Min (dBm) and Max (dBm) values to the optimal range. This ensures the full color spectrum is used to represent your data, making the heatmap visualization as detailed and informative as possible without manual adjustment.

Reset Zoom: A button that returns the map view to its default zoom level, showing the entire surveyed route.

Save CSV: A button that exports the underlying raw or aggregated measurement data into a Comma-Separated Values (CSV) file.

Selected Data Points: This section is interactive. When you click on a specific data point or area on the heatmap, detailed information about that particular measurement (such as exact frequency, signal strength, timestamp, and GPS coordinates) will be displayed here.

Aggregation Method Selector

Average / Maximum / Minimum: This setting determines how multiple signal strength measurements taken in the same geographic area are combined into a single color on the heatmap.

• Average: Shows the mean signal strength. This is best for understanding general coverage.
• Maximum: Shows the strongest signal recorded. Useful for finding the peak performance in an area.
• Minimum: Shows the weakest signal recorded. Crucial for identifying dead spots or areas of poor coverage.

 Survey Information Panel

• Total Sweeps: The total number of individual RF measurements taken during the survey.
• Aggregated Points: The number of discrete points or areas shown on the current heatmap view, which are a summary of the total sweeps.
• Device Information: Details about the RF Explorer device and input stage used to collect the data.
• Frequency Range: The specific band of the radio spectrum that was scanned.
• Start/Stop Time: The date and time (in UTC) when the survey began and ended.
• Sample Time: The interval at which measurements were automatically taken in seconds.

Route Statistics Panel

• Metric/Imperial
  • This is a unit toggle switch for the displayed map and route statistics.
  • Metric (km, km/h): When selected, distances are shown in kilometers (km) and speeds in kilometers per hour (km/h).
  • Imperial (mi, mph): When selected, distances are shown in miles (mi) and speeds in miles per hour (mph). This allows users to view the data in their preferred measurement system.
• Total Linear Distance: The total length of the travel path during the survey
• Average Speed: The average speed during the survey
• Sample Distance: Statistics on the distance between each measurement point.
  • Max / Avg / Min: The longest, average, and shortest distances between consecutive data samples.

You can download a ZIP package containing sample heatmap files to explore the application’s features.
The package also includes an activity capture with GPS data, allowing you to test and analyze location-based functionalities.
