2G Radio Profile

Context

A 2G radio profile is used to configure and optimize the 2G radio of an AP, but does not take effect on the 5G radio. Create a proper radio profile and bind it to an AP specific profile or AP group. In this way, the AP provides better radio signal transmit and receive capabilities.

Procedure

Create a 2G radio profile.

Choose Configuration > Wireless Services > Profile > Radio Management > 2G Radio Profile. The 2G Radio Profile List page is displayed.
Click Create. The Create 2G Radio Profile page is displayed.
Enter the name of the new 2G radio profile in Profile name.
To copy all parameters from another profile to the new profile, select the name of the profile in Copy parameters from other profiles. If None is selected, parameters are not copied from another profile.
Click OK. The parameter setting page of the new 2G radio profile is displayed.

Set parameters for the 2G radio profile. Table 1 describes the parameters for creating a 2G radio profile.

**Table 1** Parameters for creating a 2G radio profile
Parameter	Description
2G Radio Profile	Name of the 2G radio profile, which cannot be modified.
Radio type	Radio type.
Automatically disable radio	Whether to enable the automatic shutdown function of a radio.
Automatic disabling time	Start time and end time during which a VAP is disabled.
Meanings of Wi-Fi indicator status	Parameter reflected by the blinking frequency of the Wireless indicator. Signal strength: The blinking frequency of the Wireless indicator on an AP indicates the signal strength. When the Wireless indicator blinks fast, the signal strength is strong. Service traffic: The blinking frequency of the Wireless indicator on an AP indicates the service traffic volume. When the Wireless indicator blinks fast, the service traffic volume is high.
Channel switching announcement	Whether channel switching announcement is enabled.
Channel switching announcement mode	Channel switching announcement mode, which can be: Stop traffic transmission: stops data transmission from STAs on the current channel during channel switching. Proceed traffic transmission: continues data transmission on the current channel during channel switching.
Packet-based power control	Whether per-packet power control is enabled.
Packet fragmentation threshold	Package length threshold for fragmentation.
RTS-CTS mode	RTS/CTS operation mode, which can be: Cts-to-self: When an AP needs to send data to STAs, it sends a CTS packet with its IP address as the source and destination addresses. Then none of the devices within the AP's coverage area sends data within a specified period. In cts-to-self mode, an AP only needs to send a CTS packet to avoid channel conflicts in most scenarios. However, if there is a device within the STA's coverage area but not within the AP's coverage area, a channel conflict may still occur. Rts-cts: When an AP needs to send data to a STA, the AP sends an RTS packet to all STAs associated with it. After receiving the RTS packet, none of the devices within the AP's coverage area sends data within a specified period. After the destination STA receives the RTS packet, it sends a CTS packet. After receiving the CTS packet, none of the devices within the STA's coverage area sends data within a specified period. Using the rts-cts mode to avoid conflicts requires two packets (RTS and CTS packets), increasing packet overhead. Disable: disables RTS-CTS.
RTS-CTS threshold	RTS/CTS threshold.
Support short preamble	Whether short preamble is supported.
Beacon interval	Interval at which an AP sends Beacon frames.
Utmost power	Whether a radio sends packets at the maximum power. Only radios of the AD9431DN-24X (including the mapping RUs), AD9430DN-24 (including the mapping RUs), AD9430DN-12 (including the mapping RUs), AP2030DN, AP4030DN, AP4130DN, AP5030DN, AP5130DN, AP7030DE, AP8030DN, AP8130DN, AP9131DN, AP9132DN and AP9330DN can send packets at maximum power.
Self-adaptive polarization of agile antennas	Self-adaptive polarization of agile antennas.
802.11n
GI mode	Guard interval mode. Short: short guard interval Normal: normal guard interval
Beamforming	Whether beamforming is enabled.
HT AMPDU	Whether MPDU aggregation is enabled.
Index of maximum length of HT AMPDUs	Maximum length of an A-MPDU. The value ranges from 0 to 3. 0: indicates that the maximum length of the A-MPDU is 8191 bytes. 1: indicates that the maximum length of the A-MPDU is 16383 bytes. 2: indicates that the maximum length of the A-MPDU is 32767 bytes. 3: indicates that the maximum length of the A-MPDU is 65535 bytes.
802.11bg Rate Set
Basic rate (Mbps)	Basic rate set of 802.11bg.
Supported rate (Mbps)	Supported rate set of 802.11bg.
Multicast rate (Mbps)	Multicast rate of wireless packets on the 2.4 GHz radio.
Interference Detection
Interference detection	Whether interference detection is enabled.
AP co-channel interference alarm threshold (%)	Alarm threshold for co-channel interference.
AP adjacent-channel interference alarm threshold (%)	Alarm threshold for adjacent-channel interference.
STA interference alarm threshold	Alarm threshold for STA interference.
WMM
WMM	Whether WMM is enabled.
Restrict access of non-WMM terminals	Whether to allow WMM-incapable STAs to connect to a WMM-enabled AP.
Area	Provides different preset values for the EDCA parameters in different scenarios. You can directly select a specific scenario or make an adjustment to the preset values. Default: specifies the default of an EDCA parameter. Voice: indicates that voice packets preempt a channel. Voice and video: indicates that voice and video packets preempt a channel.
Packet Type	Type of packets.
AIFSN	Arbitration inter frame spacing number (AIFSN), which determines the channel idle time. In the distributed coordination function (DCF) protocol, the DCF inter frame space (DIFS) has a fixed value. WMM provides different DIFS values for different ACs. A larger AIFSN value indicates that the STA must wait for a longer time and has a lower priority.
ECWmin	Exponent form of the minimum contention window. ECWmin and ECWmax determine the average backoff time. A larger value indicates a longer average backoff time and a lower priority.
ECWmax	Exponent form of the maximum contention window. ECWmax and ECWmin determine the average backoff time. A larger value indicates a longer average backoff time and a lower priority.
TXOPLimit	Transmission opportunity limit (TXOPLimit). It determines the maximum duration in which an STA can occupy a channel. A larger value indicates a longer duration. If the TXOPLimit value is 0, the STA can send only one data frame every time it preempts a channel.
ACK Policy	ACK policy, which includes: Reply: During 802.11 packet exchange, the receiver sends an ACK packet to confirm the receiving of a packet from the sender. No reply: The receiver sends no ACK packet to confirm the receiving of a packet from the sender. It applies to scenarios where communication quality is good and interference is low.
