Returns
`String`

getPasspointProviderFriendlyName

public String getPasspointProviderFriendlyName ()

Returns the Provider Friendly Name of the network if it is a Passpoint network.

The Provider Friendly Name may be null if no network currently connected, currently connected network is not passpoint network or the caller has insufficient permissions to access the Provider Friendly Name.

Returns
`String`

getRssi

public int getRssi ()

Returns the received signal strength indicator of the current 802.11 network, in dBm.

Use WifiManager.calculateSignalLevel(int) to convert this number into an absolute signal level which can be displayed to a user.

Returns
`int`	the RSSI.

getRxLinkSpeedMbps

public int getRxLinkSpeedMbps ()

Returns the current receive link speed in Mbps.

Returns
`int`	the Rx link speed or `LINK_SPEED_UNKNOWN` if link speed is unknown. Value is -1 or greater

See also:

LINK_SPEED_UNKNOWN

getSSID

public String getSSID ()

Returns the service set identifier (SSID) of the current 802.11 network.

If the SSID can be decoded as UTF-8, it will be returned surrounded by double quotation marks. Otherwise, it is returned as a string of hex digits. The SSID may be WifiManager#UNKNOWN_SSID, if there is no network currently connected or if the caller has insufficient permissions to access the SSID.

Prior to Build.VERSION_CODES.JELLY_BEAN_MR1, this method always returned the SSID with no quotes around it.

Returns
`String`	the SSID.

getSupplicantState

public SupplicantState getSupplicantState ()

Return the detailed state of the supplicant's negotiation with an access point, in the form of a SupplicantState object.

Returns
`SupplicantState`	the current `SupplicantState`

getTxLinkSpeedMbps

public int getTxLinkSpeedMbps ()

Returns the current transmit link speed in Mbps.

Returns
`int`	the Tx link speed or `LINK_SPEED_UNKNOWN` if link speed is unknown. Value is -1 or greater

See also:

LINK_SPEED_UNKNOWN

getWifiStandard

public int getWifiStandard ()

Get connection Wi-Fi standard

Returns
`int`	the connection Wi-Fi standard Value is `ScanResult.WIFI_STANDARD_UNKNOWN`, `ScanResult.WIFI_STANDARD_LEGACY`, `ScanResult.WIFI_STANDARD_11N`, `ScanResult.WIFI_STANDARD_11AC`, or `ScanResult.WIFI_STANDARD_11AX`

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.
