DTIM Interval
The interval for sending the Delivery Traffic Indication
Message (DTIM). A DTIM field is a countdown field
informing clients of the next window for listening to
broadcast and multicast messages. When the WRP500
has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM
Interval value. Its clients hear the beacons and awaken
to receive the broadcast and multicast messages. Enter
a value between 1 and 255.
Default: 1
RTS Threshold
The WRP500 sends Request to Send (RTS) frames to a
particular receiving station and negotiates the sending
of a data frame. After receiving an RTS, the wireless
station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission. If you
encounter inconsistent data flow, only minor reduction
of the default value,
2347
, is recommended. If a
network packet is smaller than the preset RTS threshold
size, the RTS/CTS mechanism will not be enabled.
Default: 2347
