# isExtendedDistanceMeasurementEnabled

A Boolean value that indicates whether both peers can use extended distance measurement for this Nearby Interaction session instance.

## Declaration

```swift
var isExtendedDistanceMeasurementEnabled: Bool { get set }
```

## Discussion

Discussion If true, the NISession uses extended distance measurement (EDM) capabilities while ranging with a peer that’s also capable of EDM. This property is compatible with the isCameraAssistanceEnabled property. To understand the shared capabilities of the devices, check the supportsExtendedDistanceMeasurement property in the deviceCapabilities properties on NISession, and the deviceCapabilities property on the NIDiscoveryToken generated by the peer device.
