8.7.12 SSID List

The SSID list screen allows you to create and manage SSID configurations that can be used by the
APs. An SSID, or Service Set IDentifier, is basically the name of the wireless network to which a
wireless client can connect. The SSID appears as readable text to any device capable of scanning
for wireless frequencies (such as the WiFi adapter in a laptop), and is displayed as the wireless
network name when a person makes a connection to it.

DESCRIPTION
Use RTS/CTS to reduce data collisions on the wireless network if you have wireless clients
that are associated with the same AP but out of range of one another. When enabled, a
wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send)
before it transmits. This stops wireless clients from transmitting packets at the same time
(and causing data collisions).
A wireless client sends an RTS for all packets larger than the number (of bytes) that you
enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn
RTS/CTS off.
The threshold (number of bytes) for the fragmentation boundary for directed messages. It
is the maximum data fragment size that can be sent. Enter an even number between 256
and 2346.
When a wirelessly networked device sends a beacon, it includes with it a beacon interval.
This specifies the time period before the device sends the beacon again. The interval tells
receiving devices on the network how long they can wait in low-power mode before
waking up to handle the beacon. This value can be set from 80ms to 1000ms. A high value
helps save current consumption of the access point.
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Active Power Management mode.
A high DTIM value can cause clients to lose connectivity with the network. This value can
be set from 1 to 255.
Set the output power of the AP in this field. If there is a high density of APs in an area,
decrease the output power of the AP to reduce interference with other APs. Select one of
the following 100%(Full Power), 50%, 25%, or 12.5%. See the product specifications
for more information on your NXC5200's output power.
Note: Reducing the output power also reduces the NXC5200's effective broadcast radius.
This section controls the data rates permitted for clients.
For each Rate, select a rate option from its list. The rates are:
• Fast Select - Select an 802.11 broadcast frequency to determine the baseline rate
configuration.
• Basic Rate (Mbps) - Set the basic rate configuration in Mbps.
• Support Rate (Mbps) - Set the support rate configuration in Mbps.
• MCS Rate - Set the MCS rate configuration.
This section allows you to associate an SSID profile with the radio profile.
Select and SSID and click this button to reassign it. The selected SSID becomes editable
immediately upon clicking.
Indicates which SSID profile is associated with this radio profile.
