Hi Vincent,
I have tried short distance with ddwrt and i get 1733/1733 datarates and about 1Gbps real traffic using iperf. Ubiquiti and MikroTik have 80MHz outdoor radios and they work good. I don't want to use 160MHz which is very wide and there are lot of 20MHz channels within that will create interferences. Actually i want to benefit from VHT-NSS4 so at 80MHz channel i will get 1560Mbps. Ben Greear also thinks that is something wrong with ACK timing.From: Vincent Wiemann <[email protected]> Sent: Friday, 20 September 2019, 21:56 To: [email protected]; [email protected] Subject: Re: [OpenWrt-Devel] QCA9994 outdoor 13km link Hi Klevis, have you tried it with a short distance? If you did you should better ask Ben Greear directly. By the way ath10k gen 2 chipsets don't work very well with long distance links without a special feature which implementation is only available to companies like Ubiquiti and very few people who have an own reverse-engineered implementation. It works on IPQ401X, QCA9886 and QCA9888 based chips only. And it is not possible to set a coverage class for gen 2 devices, yet as far as I know due to missing documentation and implementation (correct me if that information is outdated). Furthermore a high channel width often results in problems due to lower receiver sensibility. We have better experiences with lower channel widths and sometimes get more throughput with that. Actually I think this does not explain your connection issues as 13 km is not that much.
