Radio Profile
Overview
Radio profiles are used to optimize radio parameters, and control the in-service channel switching function.
- 2G radio profiles allow you to configure the 802.11bg rate set.
- 5G radio profiles allow you to configure the 802.11a rate set, and perform 802.11ac-related configurations.
- Air scan profiles are designed for radio calibration, spectrum analysis, location, and WIDS data analysis. APs periodically scan radio signals in their surrounding environment and report the collected information to ACs or servers.
- RRM profiles are designed to maintain optimal radio resource utilization. They enable APs to check the surrounding radio environment, dynamically adjust working channels and transmit power, and evenly distribute access users. This function helps adjust radio coverage, reduce radio signal interference, and enable a wireless network to quickly adapt to changes in the radio environment. With the radio resource management function, the wireless network can provide high service quality for wireless users.

Radio type |
Radio type. |
Automatically disable radio |
Enable or disable the automatic shutdown function of the radio. By default, this function is disabled. |
Automatic disabling time |
Start time and end time during which the radio is disabled. |
Meaning of Wi-Fi indicator status |
Parameter reflected by the blinking frequency of the Wireless indicator. Only APs having wireless LEDs support this function. |
Channel switching announcement |
If the AP channel switches, the AP sends an Action frame to instruct STAs to switch channels after multiple Beacon intervals. The AP also switches the channel after the same intervals. The AP and STAs switch channels at the same time to prevent STA reassociations and ensure rapid service recovery. |
Channel switching announcement mode |
This function must be supported by both the AP and STA. |
Packet-based power control |
An AP detects the signal strength of a STA in real time. If the signal strength of the STA is strong (for example, when the STA is near the AP), the AP reduces its transmit power when sending packets. If the signal strength of the STA is weak (for example, when the STA is far from the AP), the AP uses the normal transmit power to send radio signals. |
RTS-CTS mode |
RTS/CTS operation mode, which can be:
|
Beacon interval (TUs) |
An AP broadcasts Beacon frames at intervals to notify STAs of an existing 802.11 network. After receiving a Beacon frame, a STA can modify parameters used to connect to the 802.11 network. The following intervals for sending Beacon frames are recommended for APs with different VAP quantities on a single radio (except the AP7030DE and AP9330DN):
The value range is 60 to 1000. The default value is 100. |
Autonavigation roaming beacon interval (TUs) |
Interval at which Beacon frames for the automatic navigation roaming optimization function are sent. This configuration takes effect only when the autonavigation function is enabled. The value range is 60 to 100. The default value is 60. |
Utmost power |
Maximum power for radios to send packets. If the country code is CN, radios can send packets at the maximum power when Default is selected. In other cases, radios can send packets only at the power specified in the local country. |
Self-adaptive polarization of agile antennas |
For 1x1 and 2x2 STAs, an AP reserves only two antennas whose polarization directions are mutually orthogonal. This ensures that the polarization diversity gain will not be weakened and improves the transmit power of antenna ports, thereby improving the SNR on the STA side. However, this feature has restrictions on antenna installation: The reserved two antennas must be connected to chainA and chainB. |
CCA threshold (dBm) |
The CCA threshold is used to determine whether the channel is idle. Modifying this parameter may affect uplink access coverage or STA access. Perform modification under the guidance of technical personnel. The value range is -85 to -40. |
GI mode |
During data transmission, the receive and transmit ends do not receive or send data at all times. There is an interval between the first and second data receiving or transmission or among multiple transmissions. The interval is called Guard Interval (GI) and can improve the transmission effect. |
Beamforming |
Enable or disables the beamforming function. Beamforming is a signal processing technique that controls signal transmission direction, and transmission and reception of radio signals. The transmit end uses weight to transmit signals. The signals are transmitted to the destination as narrow beams. Beamforming increases the SNR for the destination device. |
Basic rate (Mbit/s) |
Contains rates that STAs must support. If a STA does not support any rate in the BSS, the STA cannot go online. |
Supported rate (Mbit/s) |
Contains rates that STAs desire to support. STAs can properly go online even if they do not support rates in the supported rate set. |
Multicast rate (Mbit/s) |
Rate of wireless multicast packets. |
Radio environment detection |
WLAN wireless channels are vulnerable to interference in surrounding radio environments, and the service quality is therefore degraded. If radio environment detection is configured, a monitor AP can know the radio environment in real time and report alarms to the AC in a timely manner. |
AP co-channel interference alarm threshold (%) |
Two APs working on the same frequency band interfere with each other. When the AP detects that co-channel interference exceeds the alarm threshold, the AP sends an alarm to the AC. The value range is 1 to 100. The default value is 50. |
AP adjacent-channel interference alarm threshold (%) |
Two APs with different center frequencies have overlapping areas, resulting in adjacent-channel interference. When the AP detects that adjacent-channel interference exceeds the alarm threshold, the AP sends an alarm to the AC. The value range is 1 to 100. The default value is 50. |
STA interference alarm threshold (STA count) |
If many STAs associated with other APs exist around an AP, services of the STAs associated with the local AP may be affected. When the AP detects that the number of such STAs exceeds the alarm threshold, the AP sends an alarm to the AC. The value range is 1 to 256. The default value is 32. |
WMM |
802.11n and 802.11ac STAs must support WMM. If the WMM function is disabled in a radio, 802.11n and 802.11ac cannot work and STAs can access the network only in 802.11a/b/g mode. |
Restrict access of non-WMM terminals |
You can disable STAs that do not support WMM from connecting to a WMM-enabled AP, which prevents those STAs from preempting channels of WMM-capable STAs. |
Antenna training |
Smart antenna training interval. The default value is Auto. |
Antenna training interval (s) |
Configure the self-defined smart antenna training interval based on actual situations. The value range is 10 to 600.
|
Lower valid PER threshold (%) |
The PER is a key basis for the smart antenna algorithm. After proper upper and lower valid PER thresholds are configured, the smart antenna algorithm can select a proper antenna combination to improve the coverage and anti-interference capability of a WLAN in indoor coverage scenarios. |
Upper valid PER threshold (%) |
The PER is a key basis for the smart antenna algorithm. After proper upper and lower valid PER thresholds are configured, the smart antenna algorithm can select a proper antenna combination to improve the coverage and anti-interference capability of a WLAN in indoor coverage scenarios. |
Throughput-triggered training threshold (%) |
In a smart antenna system, the device monitors performance (throughput) of transmit ends. If the detected throughput of a transmit end exceeds the sudden performance change threshold specified, a new round of antenna training is triggered.
|
Number of training packets |
To set the number of MPDUs sent by an AP to a STA during smart antenna training. If the traffic rate, bandwidth, and air interface rate of the STA are high, set a small value. Otherwise, set a large value. The value range is 10 to 1000. The default value is 640. |
