|
|
+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.
