the Received Signal Strength Indicator (RSSI) methodology to determine if other smartphones are within the two-metre proximity zone by measuring the strength of the signal between devices. As such, you may know which smartphones are in your proximity zone, but not where they are relative to each other.
Wyld uses collective positioning technology that makes it possible to relatively position each smartphone to each other and create a dynamic geofence for a personal two-metre proximity zone. The advantage of relative positioning with a multi-hop mesh network is that the app understands how far away another smartphone or person might be, but also other potential nearby groups that could be affected.
Wyld is currently talking to NHSX as well as engaging with other potential tech company partners.
