![]() If you can’t run Ethernet to all of your APs and need to rely on wireless backhaul, you should leave this enabled. Mesh APs rely on wireless backhaul rather than wired, but otherwise operate like any other UniFi AP. Wireless Meshing controls whether or not there is a hidden SSID broadcast, which allows other UniFi APs to connect to the network wirelessly. These settings used to be part of the global AP rules, but have migrated to Settings -> System -> Advanced. Recommendation: Leave enabled if you prefer ease of use, disable if you are manually setting channels. You can apply this to all APs, or only APs configured to auto channel. For most networks, especially with less experienced administrators, auto channel optimization usually leads to good results. It attempts to automatically pick the best channels for you, and usually does a good job.įor high-density networks where careful channel planning is important, manual selection is best. Optimize Channelization (Nightly Channel Optimization) is an automated process that looks at all connected UniFi APs and the RF environment they are in. You can hit the “X” on the right to apply the global rules, or go to their device settings panel and toggle the global rules there. Keep 2.4 GHz around 6 dBm lower than 5 GHz or 6 GHz in multi-AP networks if you want to keep their coverage area roughly the same.ĪP Exclusions is a list of APs that are excluded from the global rules. If setting manually, use the lowest power level that still results in good coverage and signal strength. Recommendation: Auto is a good default, but usually results in maximum power. For those trying to achieve the most range and coverage from the APs they have, high 5 GHz and 6 GHz TX power can be set. If you have a very dense area or multiple APs, setting a unique channel and keeping 5 GHz TX power on low or medium may be best. This can lead to better performance and more reliable roaming.ĥ GHz and 6 GHz signals attenuate more rapidly and are more affected by obstructions, resulting in around half the range of 2.4 GHz. In a multi-AP network, turning down 2.4 GHz transmit power helps balance the inherent difference in range. Higher power levels can also increase co-channel or adjacent-channel interference, so it is a balancing act.Ģ.4 GHz signals travel longer distances, and through obstructions like walls or trees more effectively than 5 GHz or 6 GHz signals. ![]() The actual dBm values for low, medium, and high are based on the AP model and what they are capable of.īroadly speaking, higher transmit power means longer range, higher signal-to-noise, and higher throughput. Transmit Power allows you to set TX power for your radios to low, medium, high, auto, or a custom value.
