WL1837MOD: Calibrator tool to verify 5GHz functionality

Raeesa Ashique

Part Number: WL1837MOD


I am using the calibrator commands to put the module into a particular mode of operation, as described here: http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing

For testing 802.11a band, I set the channel using: calibrator wlan0 wl18xx_plt tune_channel 36 1 1

I am unsure how to set the transmission rate (for setting data rate and modulation scheme), to correspond to a particular 5GHz channel. For example, if channel 36 corresponds to a data rate of 6 Mbps, then why shouldn't I set rate =4?

Thanks

    Hi,

    There is no relation between the channel number and the data rate.

    The tune channel is used to set the channel (for example to 36):

    Then the plt_start_tx is started with the value of 19:

    19 = 65.0 Mbps (MCS7)

    so it will transmit on channel 36 at an MCS7 rate.

    5GHz TX:
    20MHz 

    calibrator wlan0 wl18xx_plt stop_tx
calibrator wlan0 wl18xx_plt tune_channel 36 1 1
calibrator wlan0 wl18xx_plt set_tx_power 20000 0 1 36 0 0 0 1 0 0 0 0
calibrator wlan0 wl18xx_plt start_tx 400 19 3000 0 0 0 0 0 00:11:22:33:44:55 01:02:03:04:05:06 0
