# init(networkIdentifier:discoveryMethod:)

Initializes a DL-TDOA configuration with a network identifier and discovery method.

## Declaration

```swift
init(networkIdentifier: Int, discoveryMethod: NIDLTDOAConfiguration.DiscoveryMethod)
```

## Parameters

- `networkIdentifier`: An ID that distinguishes among multiple tracked areas if there’s more than one tracked area in the vicinity.
- `discoveryMethod`: The technology that the session uses to discover DL-TDOA anchors.

## Discussion

Discussion Use this initializer to create a DL-TDOA configuration that specifies a network identifier for a specific tracked area and the method it uses to discover anchors in the tracked area. The network identifier corresponds to the session ID configured in the DL-TDOA anchors. Anchors with the same session ID belong to the same tracked area. Specify the method your app uses to discover anchors among NIDLTDOAConfiguration.DiscoveryMethod.wifi and NIDLTDOAConfiguration.DiscoveryMethod.bluetoothLowEnergy to match the infrastructure in your deployment environment. let configuration = NIDLTDOAConfiguration(     networkIdentifier: 1,     discoveryMethod: .wifi ) session.run(configuration)
