- Subject: [PATCH 1/2] rt2x00: reduce tx power to nominal level on RT6352
- Date: Thu, 27 Dec 2018 15:05:25 +0100

- X-Mailing-List: [email protected]
- X-Virus-Scanned: ClamAV using ClamSMTP
- 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.
