12.2.1.3.5 Configuring Transmission Properties
The procedure below describes how to configure wireless transmission properties.

To configure the transmission properties:
1. Access the Wireless tab screen.
Figure 12-60: Transmission Parameters in Wireless Tab Screen
2. From the ‘CTS Protection Mode’ drop-down list, select whether you want to enable or
disable this feature (Select ‘Always' to enable CTS or 'Auto' to have the device
automatically decide whether or not to use this feature). CTS Protection Mode boosts
your device's ability to intercept 802.11g and 802.11b transmissions. Conversely, CTS
Protection Mode decreases performance. Leave this feature disabled unless you
encounter severe communication difficulties between the device and 802.11g
products.
3. In the ‘Beacon Interval’ field, enter how often the beacon packet is sent. A beacon is a
packet broadcast by the device to synchronize the wireless network.
4. In the ‘DTIM Interval’ field, enter the Delivery Traffic Indication Message (DTIM)
countdown value that informs wireless clients of the next opportunity to receive
multicast and broadcast messages. This value ranges between 1 and 16384.
5. In the ‘Fragmentation Threshold’ field, enter the packet size threshold above which
packets are fragmented into multiple packets. Try to increase the fragmentation
threshold if you encounter high packet error rates. Do not set the threshold too low,
since this can result in reduced networking performance.
6. In the ‘RTS Threshold’ field, enter the packet threshold size below which the Request
to Send (RTS) / Clear to Send (CTS) mechanism are not active. This sends RTS
packets to the wireless client to negotiate the dispatching of data. The wireless client
responds with a CTS packet, signaling that transmission can commence. If you
encounter inconsistent data flow, try a slight reduction in the RTS threshold size.
