Hi TI Team,
We are doing WLAN RF Performance test for WL1831MOD chipset in our product. We are using backports-3.14-1 WiFi driver stack and wl18xx-fw-2.bin. We are calibrating wl18xx-conf.bin using steps given in http://processors.wiki.ti.com/index.php/WL18xx_Calibration_Process. We are configuring Data rate and Transmitter power as per "WLAN 2.4-GHz Transmitter Power" section in Datasheet (Version: SWRS152H), using steps given in http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing.
In our RF test, We are getting proper output power for Data rates from 5.5 Mbps to 54 Mbps. But for 1 Mbps and 2 Mbps DSSS data rates, when we configure 17.3 dBm Tx power, We are getting only 12.3 dBm and 12.9 dBm respectively. We are using Channel 9 in 2.4GHz band and 20 MHz bandwidth. Below are the commands used for this test:
calibrator wlan0 plt power_mode on
calibrator wlan0 wl18xx_plt tune_channel 9 0 1
calibrator wlan0 wl18xx_plt set_tx_power 17300 0 0 9 0 0 0 0 0 1 0 0
calibrator wlan0 wl18xx_plt start_tx 200 0 1024 0 0 0 0 0 84:dd:20:9b:e8:79 34:23:87:df:48:71 0
Please help us in fixing this issue.
