BPI-R4 new design for 5G gateway, support OpenMPTCPRoutuer.
any good project with this design???

Isn’t it a little too overkilled? Would the chip in question be able to manage + 5G modem at the same time? With the current mediatek chips the bottleneck is the cpu that does not know how to handle the interrupts of the usb/pcie well
Any plan of adding PoE-out on the RJ45 ports? I would like to have one of those rack mounted as a gateway and multiple BPIs as APs, like the AC+AP deployment. It would be helpful for multi floor townhomes,
I think having six M.2 Key B slots hosting six 4G/5G modems is excessive, especially since there is currently no hardware offload available for the USB interface. Based on what you’ve shared, those ports are connected to a USB 3.0 switch. Theoretically, with two USB 3.0 switches (each offering 5 Gbit/s) shared across the slots, the bandwidth per port would be around 4/5 = 0.8 Gbit/s. Additionally, we need to account for interrupts on the controller, which the CPU may struggle to handle efficiently.
Let me know if I’m saying something wrong or if this actually makes sense.
I think that those who can get 0.8Gbps from one modem don’t need mptcp.
What would be a real-world use-case for such a 5G gateway?
So you need 6 SIM cards/contracts - I guess this might not be that cheap? Or is it to circumvent carrier data caps - so you get some kind of prepaid data and just get 6 cheap prepaid SIM cards?
OpenMPTCProuter permit to aggregate multiple Internet connections with the help of Multipath TCP (MPTCP).
Yes I read that, but why would you aggregate six 5G connections? I‘m really curious, as this is very uncommon (nobody) here where I live, so I‘m really interested how this feature is actually used - it must make sense in some countries or for special use cases?
I see, wow 16 modems! So you do it, because there is no ISP providing wired access (cable, fiber, DSL, …) in your area? In my area, 16 modems = 16 contracts would cost 16x 20.- EUR = 320 EUR per month, so this would be way more expensive than wired access (30 EUR per month) or even satellite, even a single 5G connection would deliver 1G up/down, so there is some data/bandwidth cap per contract? It is really interesting, how the economics of internet is different in all regions on Earth…
OpenMPTCProuter currently support to aggregate up to 8 connections (or 8 IPs in fact). I’ve made a patch to support more but I don’t have so many connections to test…
BPI-R4 and BPI-R4 PoE are supported in v0.62 RC1 (I hope to be able to release v0.62 soon…)
please add PoE, that would really make sense instead of tons of RJ45
This is a special use case, specifically for 5G aggregation,
We will release another product that supports multiple 2.5G RJ45 and POE PD.
