RTS threshold
Transmitted wireless packets larger than this size will use the RTS/CTS
protocol to (a) maintain performance in noisy wireless networks and (b)
prevent hidden nodes from degrading performance. To minimize the
potential packet collision associated with hidden nodes in a wireless
network, IEEE 802.11 standard has the option to complete a “Request to
Send (RTS)” and “Clear to Send (CTS)” two-frame exchange prior to
sending the real data. This reduces the throughput of the real data. Since
the probability of packet collision increases with the size of the packets
transmitted, an optimum trade-off between data-throughput and data-
integrity may be reached by turning on the two-frame exchange only for
data packets exceeding a certain size. The number entered in this field is
that threshold packet size in Bytes. For example, if “500” is entered, data
packets with sizes less than 500 bytes are transmitted without being
preceded by the RTS-CTS exchange and thereby taking a small risk of
getting corrupted by packet collisions. If “2432” (the maximum 802.11 data
frame size) or a larger number is entered, then every data packet is
transmitted without being preceded by the RTS-CTS exchange and
thereby maximizing the data throughput. The valid range of RTS threshold
is 1 to 3000.
