| 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 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.
|
| 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.
