Use this screen to configure radio settings for all access points in the network.
Double-click one of the networks on Org-Trees > Configure > Radio Settings.
The settings and options in the Radio Setting page apply to all access points in a network, and you can configure the following settings:
This option allows users to customize the channels. On the Auto setting, EnGenius access points automatically adjust the channels of their radios to avoid RF interference.
The use of 40 MHz channels on the 2.4 GHz band does not provide for multiple independent channels in multi-AP deployments for 2.4GHz. The recommended setting is 20MHz. To maximize throughput, use 40 MHz for 802.11n and 80 MHz for 802.11ac for 5GHz. Note that higher density deployments should use 20 MHz or 40 MHz channels on 5 GHz.
Using this option, users can set a custom range for Tx power.
The higher the transmission power (Tx power) of the access point, the bigger the coverage of the WiFi signal, so usually maximum power is set for an access point to connect to another access point for WDS or mesh purposes.
However, it might not be the best practice if the access point serves the purpose of being a client access point, because usually client devices (notebooks, mobile phones, etc.) might not have the same transmission power to be able to communicate back.
Current devices transmission power can be refererenced here, where most notebooks and mobile phones transmission power range from 15dBm - 25dBm. Some WiFi devices, like Amazon Echo, are in the smaller range of 10-11dBm.
If your enterprise environment is comprised mainly of notebooks and mobile phones, then it is better to turn down your access point transmission power to 15-17dBm on 5G, and 10-12dBm for 2.4G (so the coverage area of 5G and 2.4G is about the same). If you keep the same transmission power of 5G and 2.4G, it also means the signal strength of 2.4G is about 6 dB higher than 5G at the same location. Then the client device might roam from 5G to 2.4G because it detects better signal strength. It is highly recommended to leverage EnGenius ezWiFiPlanner tool to simulate coverage with different transmission power settings.
EnGenius access points can adjust the minimum bit rate for each radio (2.4G and 5G separately). When the minimum bit rate is set, an access point will send out beacons based on the minimum bit rate.
For example, if the bit rate is set to 6Mbps, then those clients with slower than 6Mbps bit rate will not be able to connect to the WiFi and will not slow down other client’s performance. 802.11b max bit rate is 11Mbps, so if 12Mbps is set per radio, then 802.11b clients will not be able to connect to the network.
The other benefit is to help better roaming, because when a client roams to a weaker RSSI signal and cause slower performance, then the access point will be kicked out, and the client will search the available SSIDs again to connect to a stronger signal SSID.
If the value is set too high, then it also means a greater density of access points are required to cover the area with the minimum bit rate. This may potentially cause more channel conflict because the transmission power of the access point remains the same, so the RF coverage area is the same and more RF areas overlap.
This is a hardware limitation, commonly applied to most access points in the market. There can be 254 clients connected to an access point at a maximum (127 clients to each 2.4G and 5G band). To serve more than 127 2.4/5G clients in a space, a higher density of access points must be deployed.
This option allows users to discard 802.11 a/b/g devices to use network to prevent from impact of performance to other 802.11ac/ax clients.
This option allows users to enable mesh on 2.4GHz or 5GHz. After you enable mesh, there is an Auto Pairing button. Access points that haven't linked to the Internet are able to scan neighborhood APs to run the mesh.
After you complete each configuration above, you can click Apply, or click Reset to revert back to the original settings.
