Hi: ALL.
I want to do some research about link adpatation via snr.I have one
problem to look for answer here. In this scenario, A and B are two nodes
in one same IEEE 802.11 wlan. when node A send one packet to node B,how
can I make node A get the snr value of the packet when the packet reachs
node B.
{{{
struct ath_tx_status {
u_int16_t ts_seqnum; /* h/w assigned sequence number */
u_int16_t ts_tstamp; /* h/w assigned timestamp */
u_int8_t ts_status; /* frame status, 0 => xmit ok */
u_int8_t ts_rate; /* h/w transmit rate index */
#define HAL_TXSTAT_ALTRATE 0x80 /* alternate xmit rate used */
int8_t ts_rssi; /* tx ack RSSI */
u_int8_t ts_shortretry; /* # short retries */
u_int8_t ts_longretry; /* # long retries */
u_int8_t ts_virtcol; /* virtual collision count */
u_int8_t ts_antenna; /* antenna information */
};
}}}
In this structure, there is one memeber named ts_rssi, what is it for? who
can explain it to me detailedly, not only the comment tx ack RSSI.
Thanks for your help very much!
