The results speak for themselves -
This is done using multiple 4G modems and a poor performing 30/5 FTTC line being combined to give one fat pipe...
My setup -
ee - Mikrotik CAT5 SXT-LTE pointed directly at the mast. (95%+ signal) - could probably do better wih a higher CAT modem with CA?
three - Sierra Wireless MC7455 with Carrier Aggregation (Band3, Band 20) with a USB3 adapter cradle running on a WDR3600 (much cheaper option than the SXT, and better performing)
talktalk - 30/5 FTTC (going to cancel it if this solution proves reliable)
VPS - internet aggregation point for the connections. using 'portfast' here but have tried 'OVH' too which works just as well.
Virtual machine running https://www.openmptcprouter.com/. This is awesome - instead of traditional load balancing it uses multipath TCP to combine multiple internet connections into a single connection and seems to work well with 'unbalanced' connections of different speeds/latencies.
all connections appear on the internet from a single IP - no problems with SSL and able to get full speed on a single stream.
OpenMPTCPRouter can run on any OpenWRT capable device I believe - going to move it from physical server hardware when i get another router ordered that can handle it.
Might help someone else get high-speed internet in the sticks. Total cost is < £100/pm including the VPS.
