Network Analysis

Find your coverage gaps.
Eliminate wasted overlap.

GridVisio automatically identifies clusters of unserved subscribers and shows you exactly where to build next. Coverage overlap analysis flags sectors sharing the same frequency band — find potential interference before it becomes a support call.

GridVisio — white area polygons (purple) and coverage overlap polygons (amber) across a 33-tower network

White area detection and coverage overlap on a live network

White area detection

Stop guessing where to put your next tower. Let your subscriber data tell you.

DBSCAN clustering — automatically

GridVisio runs DBSCAN (Density-Based Spatial Clustering) on your unserved subscribers. Clusters appear as coloured polygons on the map — each labelled with the count of unserved locations inside.

Click any white area polygon: subscriber count, centroid coordinates, and a shortcut to place a hypothetical tower at the cluster centre to estimate reach instantly.

White areas update automatically whenever you add towers, change sector parameters, or import new subscribers.

Coverage overlap analysis

Overlapping sectors on the same frequency band can cause co-channel interference. Find them before your subscribers notice.

Automatic detection

GridVisio finds all sector pairs on the same frequency band whose coverage areas overlap. Each overlap zone is drawn as an amber polygon.

Tower pair & frequency

Click any overlap polygon to see which two towers are involved, which sectors, and the frequency band. Useful for repointing or re-banding decisions.

Separate toggleable layer

Overlap polygons appear as a separate layer — visible alongside coverage sectors, subscribers, and white areas without cluttering the map.

Included in exports

Overlap zones and white areas are included in your PDF project report — useful for network reviews and grant documentation.

Plan your next tower with confidence

When you identify a white area, drop a hypothetical tower pin at the cluster centroid. The Reach Estimate panel instantly shows how many unserved subscribers fall within the configured radius and beamwidth — before you spend anything on a site survey.

Adjust radius, azimuth, and beamwidth in real time. When you're confident, promote the hypothetical tower to a real tower with one click — coverage recalculates automatically for all subscribers.

Frequently asked questions

What is white area detection?

DBSCAN (Density-Based Spatial Clustering) runs automatically on your unserved subscribers. The result is a set of polygons showing where groups of unserved subscribers are concentrated — data-driven guidance on where to build next.

How is this different from just looking at the map?

With hundreds or thousands of subscribers, it is impossible to visually identify clusters manually. DBSCAN finds statistically significant clusters based on density — filtering out isolated unserved points that are not worth building for.

What is coverage overlap analysis?

Coverage overlap analysis finds pairs of sectors from different towers that cover the same area on the same frequency band. Co-channel interference is a common cause of subscriber degradation. The analysis draws overlap zones so you can identify repointing or re-banding opportunities.

Does this work with imported subscribers?

Yes. Import via CSV or XLSX. GridVisio classifies each subscriber as served or unserved, then runs white area detection on the unserved subset automatically.

What plan do I need?

Both white area detection and coverage overlap are available on Starter ($19/month) and Pro ($39/month). The 14-day free trial includes all Starter features — no credit card required.
