Understanding the Connection Between Environment, Guess Range, and Output

Understanding the Connection Between Environment, Guess Range, and Output

1. Selecting Environment Type:

   • During project setup, select the environment type (indoor/outdoor with low/high attenuation) that matches your actual site conditions.
   • This type can be modified later in the Properties tab on the right panel under Environment.

2. Environment Type and Guess Range:

   • The environment type chosen during project setup determines the Guess Range. This is the area around your walk path where signal data is predicted or guessed. Initially you see it as a pale blue color along the path walk  with Continuous surveys or around the path points with Point-to-Point type surveys.
   • Each environment type comes with a recommended Guess Range, which can be adjusted manually in the Environment section.

3. Density of Walk Paths:

   • The density of your walk paths on the map or floor plan impacts the survey's accuracy. If the Guess Range is set to 10 feet but your walk paths are too far apart, you will see white spaces between them.

Solutions for Better Survey Results

1. Increase Guess Range:   Adjust the Guess Range value to cover a larger area around your walk paths.

2. Perform Additional Surveys:  Conduct more surveys to gather accurate and complete signal data, especially in uncovered areas.

3. Use Extrapolate Data Beyond Guess Range: Enable the "Extrapolate data beyond the Guess Range" option to extend the predicted signal data further.  Not recommended if you have many significant gaps. 

Important Considerations

• Increasing the Guess Range and using extrapolation can produce a more visually appealing result. However, if the signal data is poor, walk paths cover only a small part of the floor, or do not match the actual environment, the results will be less reliable.
• In environments with high attenuation (e.g., crowded offices with many walls, furniture, and other objects), the signal is heavily reflected and attenuated. In such cases, the Guess Range should be limited to a nearby area (typically 10-15 feet).
• In open areas with fewer obstacles, the Guess Range can be higher due to less signal attenuation and reflection.
• If your walk paths are too far apart and don't match the environment type, or leave some areas uncovered, it’s better to conduct additional surveys to ensure more accurate and reliable results.

By following these guidelines, you can optimize the accuracy and reliability of your TamoGraph Site Survey results, ensuring they accurately reflect the actual environment.
