I’m testing a Yuncore XD3200 in comparison to an UAP-AC-LITE, both running snapshot r3226-726e45d.
They have (nearly) identical hardware setup (QCA9563+QCA988x, 2 streams each), but the XD3200 has additional, external LNAs and PAs (SKY65174-21).
Both are running on channel 11, HT20, same txpower (10dBm) and same distance to the client (~2m)
While I’m only getting 18-22MBit (TCP, AP>Client) with the XD3200, the UAP-AC-LITE is stable at 38-45MBit, with the ‘stock’ XD3200 QSDK firmware and proprietary atheros driver I’m getting stable 39-41MBit.
Client readings (AP SNR):
XD3200: -53 dBm
XD3200 QSDK: -41dBm
AP readings (Client SNR):
XD3200: -48 dBm / -95 dBm (SNR 47)
XD3200 QSDK: -34 dBm / -95 dBm (SNR 61)
UAP-AC-LITE: -37 dBm / -95 dBm (SNR 58)
Rate control seems to work without problems, while I see a bit more jitter they both end up at the highest MCS rate.
My guess would be that the onboard LNA/PA are not powered on, is there any way to verify this?
(update: redid the tests with ‘stock’ QSDK Firmware, results above)
