First of all, the question is really why would anyone need a cellular router? They could be useful as a backup mechanism in case your landline internet goes down.
That’s why I first thought of this blog. Everyone on the street was WFH, kids were “going to school” on the internet, and, poof, the internet goes down. Sheer panic, right? What does everyone do? I heard screaming for sure. And more. But soon everyone goes outside to see if anyone else is having the same problem, and soon, the whole street was outside (6 feet away from each other, of course)! Yes, we felt good it wasn’t just us, but it was good the internet came back on soon enough. Some people, though, just used their 4G/LTE phone as a hotspot and kept going…
But there could be another use for a 5G router – there is WiFi, and the data needs to go out on a cellular network. This could be because some IoT data needs to be transmitted, or because it’s more secure going on a cellular network. There are numerous use cases where a cellular to Wi-Fi router/gateway could be useful.
5G is coming, and just like Wi-Fi 6 (which I wrote about a month and a half ago), you’ll need devices and networks that support 5G to take advantage of it. So if you have 5G service in your area, it could be an option on how to get internet to your house. It could be the primary method, or maybe it’s a good backup method if you tend to have spotty landline service. And like I said above, it could work the other way around to get local Wi-Fi information back out.
In this case, a 5G to Wi-Fi router might make sense as a last mile option.
