Sensors

The Sensors are classified as follows:

Software Sensors

The software-based sensor is a normal AP with one Radio in ScanSpectrum Mode. Here, the AP mode can be modified from Service/Normal Mode to ScanSpectrum Mode.

Note:

• The modification of AP mode from Service/Normal Mode to ScanSpectrum Mode can be performed only via the FortiWLC GUI or by pushing the AP template with Radio profile configured with the ScanSpectrum Mode from FortiWLM.
• You can configure both radios of FAP-U421EV, FAP-U423EV, FAP-U321EV, FAP-U323EV sensors in ScanSpectrum Mode, which will make the radios to scan both the Radio spectrum for interference. For all the other Sensors, only single radio can be configured in ScanSpectrum Mode at a time.
• No client service will be provided once Radios are configured in the ScanSpectrum

The Software Sensors include the following Access Points:

• AP1014i
• AP1010i
• AP1010e
• AP1020i
• AP1020e
• AP332i
• AP332e
• AP832i
• AP832e
• FAP-U421EV FAP-U423EV • FAP-U321EV
• FAP-U323EV

Hardware Sensors

The Hardware-based sensors are completely dedicated to monitor the airwaves of the time. By having a dedicated subsystem, the sensor can classify and report on the type and source of interference almost instantly and without taking CPU resources away from the wireless radio. The Hardware Sensors include the following Access Points:

• PSM3x
• AP433is
