Subject: [PATCH 12/28] rt2x00: reduce tx power to nominal level on RT6352
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
Current implementation of RT6352 support provides too high tx power
|
|
at least on iPA/eLNA devices. Reduce amplification of variable gain
|
|
amplifier by 6dB to match board target power of 17dBm.
|
|
Transmited signal strength with this patch is similar to that of
|
|
stock firmware or pandorabox firmware. Throughput measured with iperf
|
|
improves. Device tested: Xiaomi Miwifi Mini.
