When planning or optimizing WLANs, pay attention to working channels and corresponding transmit power of WLAN devices. Channel switching may affect signal strength, degrading network quality.
If any channel in the list does not comply with the local legal rules, contact technical support personnel.
If a country or region has two rows of channels, the first row indicates the channels supported by indoor APs, and the second row indicates those supported by outdoor APs.
- Outdoor APs: AirEngine xxxxR series, AP8000 series, AT815SN, AP6510DN-AGN, and AP6610DN-AGN
- Indoor APs or devices that can function as APs:
- WLAN devices: AirEngine series APs except AirEngine xxxxR series, AP1000 series, AP2000 series, AP3000 series, AP4000 series, AP5000 series, and AP6000 series (excluding AP6510DN-AGN and AP6610DN-AGN), AP7000 series, AP9000 series, central APs (including RUs), AP100 series, AP200 series, AP300 series, APxxxEC series, and WA375DD-CE
- AR: AR models whose names contain W, such as ARxxxW, ARxxxEW, ARxxxxVW, and SRGxxxxW
- USG series: device models whose names contain W, for example, USGxxxx-W and USGxxxx-WL
Radar Channel
Channels 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, and 144 can be used as radar channels. If the channels supported by some countries or regions overlap with the radar signals, avoid using the radar channels. In some countries or regions, more channels may be used as radar channels.
