Look at each model’s speedfusion encrypted max throughput too.
I’m not close to cell towers, and I found that a peplink max br1 mini LTEA version can get much faster and more reliable speeds than the att or verizon jetpacks or smartphone for me. Your results may vary of course, but a BR1 with external antenna has worked really well for me where my cell signal is weak.
Speedfusion works great for providing an unbreakable connection. You can also utilize some links for upload only and some for download only for example too although I haven’t done that much. In my limited experience since starting with speedfusion this summer, I’ve struggled with links that are highly variable. A slow link seems to drag the others down. You may find that bonding your worst cell links isn’t additive but instead makes it worse.
You could do a combination of bonding for unbreakable and load balancing sending some low-priority traffic over the worst cell links too. I haven’t done this year, but am thinking my ideal setup may be to create two speedfusion tunnels.
Priority has my best connection used mainly and overflows to my slower link.
Guest has my slower link used mainly and overflows to my best connection in case the slower link fails. This would be used for netflix, various less important devices for them to update, etc.
Let us know how you get it setup and how it goes!
