SummaryIssue TypeDescriptionAffects study results
TSB-88 – remove the Required Tile Reliability check from AggregatedNew Feature RequestThis enhancement requires a check for Bounded and Hess Reliability studies. This has been removed from the Aggregated studies Yes – see articles
Add “Overhead” option to Area Study dialogFeatureThis new feature is the implementation of an “Overhead” option in the Area Study dialog for LTE-M data rate enhancements.The “Overhead” option allows users to input a percentage (0-50%) in the Area Study dialog.
Overhead adjustments will impact studies, where the overhead percentage directly reduces the effective data rate. The overhead represents the portion of the transmission that is not user data (such as headers or control information), and increasing this percentage will decrease the calculated data rate for all these technologies.The default overhead is 25%, but the recent update allows users to set this value between 0–50%.  
 
LTE-M Bandwidth 1.4 MHzFeatureUpdated the LTE-M Bandwidth dropdown to contain 1.4 MHz.  image-20250804-163342.png 
Multi-link study is not pointing antennas at each otherBugInternally found, only in pdf reports and resolved 
Ensure proper caching and redisplay of previously-generated area study resultsBugDAS multi-level study layers were not stored. This has been resolved 
Multilink Study ErrorsBugAn issue with the study was found. This problem was traced to incorrect elevation data being used, which was resolved by updating link site elevations. This is resolvedYes
Issue with Rain CalculationsBugA fix was implemented to use the correct RX height AMSL, improving calculation accuracy.Yes
