Description
Allows you to configure a zone per radio band for IAPs in a cluster. You can also configure an RF zone per IAP.
Aruba recommends that you configure RF zone for either individual AP or for the cluster. Any discrepancy in the RF zone names may lead to configuration errors.
Turn on the toggle switch. When enabled, the IAP runs the radio in the non-802.11n802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz. mode. This option is disabled by default.
Turn on the toggle switch. When enabled, the radios advertise their 802.11d802.11d is a wireless network communications specification for use in countries where systems using other standards in the 802.11 family are not allowed to operate. Configuration can be fine-tuned at the Media Access Control (MAC) layer level to comply with the rules of the country or district in which the network is to be used. Rules are subject to variation and include allowed frequencies, allowed power levels, and allowed signal bandwidth. 802.11d facilitates global roaming. (Country Information) and 802.11h802.11h is intended to resolve interference issues introduced by the use of 802.11a in some locations, particularly with military Radar systems and medical devices. Dynamic Frequency Selection (DFS) detects the presence of other devices on a channel and automatically switches the network to another channel if and when such signals are detected. Transmit Power Control (TPC) reduces the radio frequency (RF) output power of each network transmitter to a level that minimizes the risk of interference. (Transmit Power Control) capabilities. This option is disabled by default.
Configures the beacon period for the IAP in milliseconds. This indicates how often the 802.11802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. beacon management frames are transmitted by the AP. You can specify a value within the range of 60–500. The default value is 100 milliseconds.
Configures the immunity level to improve performance in high-interference environments. The default immunity level is 2.
- —No ANI adaptation.
- —Noise immunity only. This level enables power-based packet detection by controlling the amount of power increase that makes a radio aware that it has received a packet.
- —Noise and spur immunity. This level also controls the detection of OFDMOrthogonal Frequency Division Multiplexing. OFDM is a scheme for encoding digital data on multiple carrier frequencies. packets, and is the default setting for the Noise Immunity feature.
- —Level 2 settings and weak OFDM immunity. This level minimizes false detects on the radio due to interference, but may also reduce radio sensitivity. This level is recommended for environments with a high-level of interference related to 2.4 GHz appliances such as cordless phones.
- —Level 3 settings, and FIR immunity. At this level, the AP adjusts its sensitivity to in-band power, which can improve performance in environments with high and constant levels of noise interference.
- —The AP completely disables PHY error reporting, improving performance by eliminating the time the IAP spends on PHY processing.
Increasing the immunity level makes the AP lose a small amount of range.
Configures the number of channel switching announcements to be sent before switching to a new channel. This allows the associated clients to recover gracefully from a channel change.
Configures a minimum (Min Power) and maximum (Max Power) power range value for the 2.4 GHz and 5 GHz band frequencies. The default value is 3 dBmDecibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors.. Unlike the configuration in the ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. profile, the transmit power of all radios in the Radio profile do not share the same configuration.
Turn on the toggle switch. When enabled, VHTVery High Throughput. IEEE 802.11ac is an emerging VHT WLAN standard that could achieve physical data rates of close to 7 Gbps for the 5 GHz band. is enabled on the 802.11ac802.11ac is a wireless networking standard in the 802.11 family that provides high-throughput WLANs on the 5 GHz band. devices for the 5 GHz radio band. If VHT is enabled for the 5 GHz radio profile on an IAP, it is automatically enabled for all SSIDsService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. configured on an IAP. By default, VHT is enabled on all SSIDs.
If you want the 802.11ac IAPs to function as 802.11n IAPs, clear this check box to disable VHT on these devices.
Turn on the toggle switch to combine an antenna array with a digital signal-processing capability to transmit and receive in an adaptive, spatially sensitive manner.
When is disabled, the Instant AP will always process frames for WIDSWireless Intrusion Detection System. WIDS is an application that detects the attacks on a wireless network or wireless system.. WIDS is an application that detects the attacks on a wireless network or wireless system. purposes even when it is heavily loaded with client traffic. When is enabled, the Instant AP will stop processing frames for WIDS.
