- 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.
