Usage Guidelines

The FFTFast Fourier Transform. FFT is a frequency analysis mechanism that aims at faster conversion of a discrete signal in time domain into a discrete frequency domain representation. See also DFT. Duty Cycle table in the output of this command shows the duty cycle for each radio channel. The duty cycle is the percentage of time each device type operates or transmits on that channel. For additional details about non-Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. device types shown in this table, see Non-Wi-Fi Interferers.

Examples

The output of this command shows that video devices sent a signal on channels 153 and 157 during 99% of the last sample interval.

Description

ap spectrum local-override

Converts an AP or AMAir Monitor. AM is a mode of operation supported on wireless APs. When an AP operates in the Air Monitor mode, it enhances the wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more. However, clients cannot connect to APs operating in the AM mode. into a spectrum monitor by adding it to the spectrum local-override list.

rf dot11a-radio-profilemodespectrum-mode

Sets an 802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps. radio so that the device operates as a spectrum monitor, and can send spectrum analysis data to a desktop or laptop client.

rf dot11g-radio-profilemodespectrum-mode

Sets an 802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network. radio so that the device operates as a spectrum monitor, and can send spectrum analysis data to a desktop or laptop client.
