LTE network access as back up for cable

I was investigating the possibility of somehow running a Cell network access to the internet as a back up access for any time that the cable network is having any local or system outages when I found the Netgear LB2120 LTE Modem which has the specific feature of setting up between the cable modem and the router and becoming a roll over connection to the internet automatically whenever the connection fails. This will be used in a retail environment where the internet is essential for item look ups, credit card processing, telephone, and more. Does anyone have experience with this device or thoughts (for or against) its implementation? It does sound like a very cost effective option to achieve near 99.999% reliable uptime for all systems (even if slightly slower at times).

System specs on account are mine, not related to this issue. This issue is for where I work daily, 12-14 Windows 10 computers, 7 credit card terminals, 5 phone lines, server, router, Wifi AP's, etc.

sound pretty good to me.

We at my office have 2 cables from 2 different providers configured in fail-over.
probably a bit to expensive for you guys tho

we do have about 120 employees and another 1500 people (cargo vessels) abroad. i believe we have about 99.97% up-time(for the office), but we always have a plan C for when when someone really needs to be online. (mobile network)

currently looking with a colleage of mine at a company similar to skyroam, for cheaper wifi for vessel that are close to or in a harbour

They did have a DSL line for fall over but after 2 years of never needing it, it was removed as being too expensive. If this works, it will be a $20. /mo. add on to the owner's personal cell bill.

I wouldn't trust mobile networks that much, unless you can get guaranties on bandwidth and throughput from the mobile operator.
In a scenario where the cable dies, chances are high everybody on that cable segment starts using mobile connections resulting in congestion.
I would go for a second internet provider (no fiber yet??) with a different physical cable route away from your prime internet provider.
Still 99.9% availability implies your internet providers have power backup on their infrastructure in case of a power disruption, not forgetting your own backup power systems....

I understand the points you bring up but a second ISP is a much larger bill every month and as mentioned, the last time until recently that there was an issue was over two years ago (maybe more) and they do not want to have that continuous billing going to effectively nothing.
The issue we are having is very localized, probably a single issue on one pole that is either a single bad wire, or other component. This single line may serve a 3-5 block square area and it gets bad intermittently, maybe wind, rain, temp change, etc. and maybe fixed permanently within a few weeks when they finally track down the errant component.
We are talking about an area that has at least 4 major cell services with strong signals so a small outage area like this would probably not significantly effect their service and slow is better than nothing.
This is New York/Long Island area and there is one cell company servicing the area, FIOS, and DSL as the only choices where none is really significantly less expensive through competition.
Finally, this is an upscale lighting store (though a large one) and if the power is down, there cannot be sales anyway and power back up is limited to keeping everything running through short power interruptions and then an orderly shut down if major. This is unfortunately out of our control so 99.9% in that light is not possible but short of that, we still are looking at significant protection, even if only for credit card processing.

I am not dismissing your points but we have to work within cost constraints and the likely hood that this once fixed may not be needed again for a couple of years.
