RF Network Parameters

RF Network Parameters include:

• Fragment Threshold: This parameter defines a threshold

above which the RF packet will be split up or fragmented. If

a packet is fragmented or transmission of part of it is

interfered with, only the portion that was unsuccessful would

need to be re-sent. The throughput will generally be lower

for fragmented packets since the fixed packet overhead

consumes a higher portion of the RF bandwidth.

• Data Retries: This parameter defines the number of times a

packet will be re-sent if the initial transmission is

unsuccessful. If the network protocol automatically re-tries

itself, set this to a small value. A “bad” packet status will be

sent up the protocol stack more quickly so the application

can re-transmit the packet.

• Basic Data Rate: This parameter determines the data rate

used to transfer all management frames by the client device

when associated within a given Basic Service Set (BSS).

When operating in Infrastructure Mode, this parameter

should be set to correspond to the Access Point setting.

When operating in Ad Hoc Mode, all stations should have

the same setting. The allowable selections for this parameter

are: 1 Mbps or 2 Mbps.

• Supported Data Rates: This parameter specifies the data

rates that will be supported by a given radio device in the

BSS. The allowable selections are: 1 Mbps, 2 Mbps, or 1 and

2 Mbps.
