ScanResult

public class ScanResult
extends Object implements Parcelable

java.lang.Object
   ↳ android.net.wifi.ScanResult


Describes information about a detected access point. In addition to the attributes described here, the supplicant keeps track of quality, noise, and maxbitrate attributes, but does not currently report them to external clients.

Summary

Constants

int CHANNEL_WIDTH_160MHZ

AP Channel bandwidth is 160 MHZ

Inherited constants

From interface android.os.Parcelable

Fields

public String BSSID

The address of the access point.

public String SSID

The network name.

public String capabilities

Describes the authentication, key management, and encryption schemes supported by the access point.

public int centerFreq0

public int channelWidth

AP Channel bandwidth; one of CHANNEL_WIDTH_20MHZ, CHANNEL_WIDTH_40MHZ, CHANNEL_WIDTH_80MHZ, CHANNEL_WIDTH_160MHZ or CHANNEL_WIDTH_80MHZ_PLUS_MHZ.

public int frequency

The primary 20 MHz frequency (in MHz) of the channel over which the client is communicating with the access point.

public int level

The detected signal level in dBm, also known as the RSSI.

public CharSequence operatorFriendlyName

Indicates passpoint operator name published by access point.

public long timestamp

timestamp in microseconds (since boot) when this result was last seen.

public CharSequence venueName

Indicates venue name (such as 'San Francisco Airport') published by access point; only available on passpoint network and if published by access point.

Public methods

boolean is80211mcResponder()
boolean isPasspointNetwork()
String toString()

Returns a string containing a concise, human-readable description of this object.
