Meraki APs with a dedicated security radio feature built-in visual spectrum analysis capabilities. The APs scan for both 802.11 (other APs) and non-802.11 sources of RF interference (eg. Bluetooth headsets, cordless phones and microwaves).
All Meraki APs also scan for interference data, which is then fed into the Meraki Auto RF planning algorithms to determine optimal channel plan (if auto-channel selection is enabled) and transmit power settings. Auto-channel selection is enabled by default and can be changed on the Radio settings page under the Configure tab.
Real-time channel utilization scans can be run from the Live Tools section of the Access Point Details page, giving an administrator both instantaneous and historical data about interference sources in the area of a particular AP. The channel utilization live tool will provide interference information on the 2.4 GHz and 5 GHz channels that the AP is broadcasting in:
All Meraki APs perform automatic networks scans to collect information about the RF environment (e.g., channel utilization, channel interference, etc.) and to detect rogue APs. There are 2 types of network scans:
Whether a network performs only opportunistic scans or performs both opportunistic and mandatory scans is configured under the Monitor tab on the Air Marshal page. The schedule for mandatory scans is also configured in this section.
For customers who want more granular control of their radio channel planning, an AP running in Air Marshal can be used to track interference in real-time across channels. An AP running in Air Marshal mode will display interference information across all channels in the 2.4 GHz and 5 GHz bands in real-time in the 'Live tools' section.
This information can be used in conjunction with the manual channel planning controls, enabling administrators to achieve fine-grained control over the RF settings of their APs.
On APs with a dedicated security radio, visual spectrum analysis data can be seen under the "RF Spectrum" page under the Monitor tab:
