Wireless 11n Properties
The wireless feature of the Access Point enables you to use the new technology called Multiple Input Multiple Output
(MIMO), that uses several antennas to transfer multiple data streams thus enabling more data to be transferred in the
same period of time. The wireless architecture is based on the cellular architecture where the systems are divided into
cells, and each cell is called the BSS.
The Wireless LAN (WLAN) can be formed of a single cell or of many cells. Each of the WLAN has an entry point which is
called Virtual Access Point (VAP). The VAP has a unique BSSID and other relevant protocols that make these VAP as
independent entity. Each of the BSSID can be configured independently so that the user can provide unique
authentication and security feature.
VAP Features
• VAP (Virtual Access Point): This is a logical entity that exists within the physical WLAN access device. The VAP
enables a single device to be divided into layers and each layer gets assigned to different users with their usage
rights.
• VAP SSID (Service Set Identifier): The VAP SSID is a unique network name used to identify a wireless network.
• VAP BSSID: This parameter represents the VAP MAC address.
• VAP Broadcast SSID: The continuous announcement of the SSID in the beacons by an AP stating that is available is
called broadcast SSID. The SSID is also broadcasted in probe response frames. Broadcasting the SSID also depends
on the type of network that the AP is running on.
• Auto Rate: Auto Rate automatically selects the data transmission rate depending on the traffic condition.
• Retries: Indicates the number of times the data packets should to be retransmitted over the wireless network.
• Legacy Rate: Indicates the rate at which the AP communicates with the Legacy Stations.
• HT (High Throughput) Rate: Indicates the rate at which the AP communicates with the HT Stations.
• Multicast Rate: Indicates the rate at which Multicast data packets are transmitted over the wireless network.
• Fragmentation Threshold: The process of dividing a MAC Service Data Unit (MSDU) into smaller MAC level frames
for transmission over the wireless network is called Fragmentation. This reduces both the probability and adverse
effects of wireless packet corruption, and thereby improving the overall wireless network performance. You can
fragment the Unicast receiver address, whereas Broadcast/Multicast frames cannot be fragmented, even though they
exceed a fragmentation threshold. You can configure fragmentation threshold up to 2346 bytes.
• Security Profile Name: This parameter allows you to configure the Security profile name for Wireless VAP. It has to
be a valid security profile configured under Wireless Security.
• RADIUS Profile Name: This parameter allows you to configure the RADIUS profile name for Wireless VAP. It has to
be a valid Radius profile configured under Security.
• VLAN ID: This parameter is used to represent the VLAN ID for the wireless VAP. Select any value between 1 - 4094 to
tag the VLAN ids and -1 to untag the VLAN ids. From VLAN perspective, the wireless port acts as an Access Point.
