Zones indoors
Use the zones you draw on the map inside buildings too, where GPS is poor or missing. Placed anchors and placed hubs help position your assets indoors, so the zones contain them.
Why indoor zones need hotspot locations
An asset's position comes from the location of the hotspot that detects it. Indoors, a mobile device's own GPS fix can be poor or old. The asset's position is then poor too, and a zone cannot tell inside from outside.
Indoor location is one problem: place each hotspot accurately. Three things give a hotspot an accurate location:
- Anchors placed on the map.
- GPS, where the hotspot has a good, recent fix.
- Hubs placed on the map.
How placed anchors help
When a hotspot detects an anchor that is placed on the map, the hotspot gets a location fix at the anchor's position. Blecon uses this fix only when it is better than the location the hotspot already has.
The assets that the hotspot detects are then positioned from that fix. Your drawn zones contain those positions, so zone entry, exit and asset counts work indoors.
An anchor without a position has no effect.
Set up zones indoors
Draw the building as a zone, add a child zone for each floor and room, then place your hubs and anchors in those zones. Set up a site walks through it step by step. Two things matter most indoors:
- Make each zone wide enough: the zone editor warns when a zone is narrower than half your accuracy filter.
- Place every hub and anchor where it is fitted. An anchor with no position has no effect. The Not placed card on Anchors and on Hubs lists any that are left.
