Max. RTS Retries
The maximum number of times the access point issues an RTS before stopping
the attempt to send the packet through the radio. Enter a value from 1 to 128.
Max. Data Retries
The maximum number of attempts the access point makes to send a packet before
giving up and dropping the packet.
Beacon Period
The amount of time between beacons in Kilomicroseconds. One Kµsec equals
1,024 microseconds.
Data Beacon Rate (DTIM)
This setting, always a multiple of the beacon period, determines how often the
beacon contains a delivery traffic indication message (DTIM). The DTIM tells
power-save client devices that a packet is waiting for them.
If the beacon period is set at 100, its default setting, and the data beacon rate is
set at 2, its default setting, then the access point sends a beacon containing a
DTIM every 200 Kµsecs. One Kµsec equals 1,024 microseconds.
Radio Channel
The factory setting for Cisco wireless LAN systems is Radio Channel 6
transmitting at 2437 MHz. To overcome an interference problem, other channel
settings are available from the drop-down menu of 11 channels ranging from 2412
to 2462 MHz.
Each channel covers 22 MHz. The bandwidth for channels 1, 6, and 11 does not
overlap, so you can set up multiple access points in the same vicinity without
causing interference.
Note Too many access points in the same vicinity creates radio congestion that can
reduce throughput. A careful site survey can determine the best placement of
access points for maximum radio coverage and throughput.
