I think that's more or less a Qualcomm reference design, and an old one at that. It's a little surprising that they went with a 2013 MIPS based SoC instead of ARM. The PCIe wireless cards are also a bit disappointing - QCA9582, which only does 802.11n. In theory, if the PCIe cards are really socketed, you could swap in a faster wireless card, but I suspect that the SoC wouldn't keep up.
- wtallis 8y agoThey're probably using 802.11n WiFi because all 802.11ac NICs require proprietary firmware, but Qualcomm-Atheros 802.11n hardware doesn't, and can be used just with fully open-source drivers.
- walrus01 8y agoI am a big believer these days in letting radios be radios - if you want a high capacity, relatively low cost 5.x GHz band PTP link, something like two ubnt AF5XHD radios and a pair of RF Elements Ultrahorn antennas. Put the routing intelligence and anything that requires a good amount of CPU and RAM in something dedicated to that purpose at each site, such as a Mikrotik RB3011 or RB4011 ($199). https://mikrotik.com/product/rb4011igs_rm https://mikrotik.com/product/rb4011igs_rm Or a home-made hacked together x86-64 system running VyOS or FRR, if you want, which can be assembled for zero dollars in many cases. Or zero dollars plus the cost of a few Intel 1000BaseT NICs.
