Two types of proximity beacons are supported: [iBeacon](https://developer.apple.com/ibeacon/) and [AltBeacon](https://altbeacon.org).

<Note>
  *WiFi Explorer Pro 3* uses your Mac's built-in Bluetooth Low Energy (BLE) radio to scan for proximity beacons.
</Note>

You can use the information provided by the *Proximity Beacon* inspector to detect the presence of proximity beacons or to design, validate, and troubleshoot the deployment of proximity beacons as part of a Wi-Fi network installation.

A list of the columns available in the *Proximity Beacon* inspector is shown below:

| Column         | Description                                                                                                                                                         |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Major          | The *major* identifier (0-65535) assigned to the proximity beacon.                                                                                                  |
| Measured Power | The received signal strength indicator (RSSI) measured at 1 meter from the proximity beacon as dBm.                                                                 |
| Minor          | The *minor* identifier (0-65535) assigned to the proximity beacon.                                                                                                  |
| Protocol       | The protocol implemented by the proximity beacon. The protocol can be either [iBeacon](https://developer.apple.com/ibeacon/) or [AltBeacon](https://altbeacon.org). |
| Proximity UUID | The Universally Unique Identifier (UUID) of the proximity beacon.                                                                                                   |
| Signal         | The current received signal strength indicator (RSSI) of the proximity beacon as dBm.                                                                               |
