WIFI_TX_RATE
This command macro specifies the maximum transmit rate for the Wi-Fi device. This rate is
reduced as necessary depending on the quality of the wireless connection. The options are:
WIFI_TX_POWER
Sets the transmit power for the Wi-Fi device. A higher transmit power will result in higher
dBm. Use the
country where the device will be used.
WIFI_FRAG_THRESH
Sets the threshold (in bytes) beyond which a frame must be fragmented when transmitted.
This can be useful on a very busy or noisy network, since frame corruption will be limited
to the size of a fragment rather than the whole frame. This means that only the fragment
will need to be retransmitted. To be effective, the fragmentation threshold will need to be
set on all wireless devices on the network as well as on the access point.
WIFI_RTS_THRESH
Sets the threshold (in bytes) beyond which an RTS (request to send) frame must be sent
before the data frame can be sent. This can sometimes help performance with busy net-
works, although it is not used frequently.
