You need a router that can take 4G/5G SIM with Wi-Fi AP connectivity. Integrated battery might not be a good idea as continuously establishing a cellular connection and offering a Wi-Fi hotspot simultaneously, would drain battery quickly.
You could try connecting the device with a portable battery pack.
The [TP-Link TL-MR3020](’
) seems like a suitable solution. But it is limited to 4G. In fact, most of such devices seem to be restricted to 4G, presumably because 5G is power hungry.
Alternatively, you can purchase a pre-owned 5G-capable smartphone. This would ensure you are primary phone is free to take calls. The secondary device would act as a battery-powered 5G modem with Hotspot capabilities.
If you have an older JioFi, you can root it to work with any SIM provider. I’ve rooted and installed the firmware on mine, and it seems to work on Airtel, though I’ve only tested it once. I don’t need it much, but I’m not sure where I kept it lol
I’ll be returning to Pune next week or so, and can search and test if you want to go down this route.
No 5G though. The best option for a 5G modem + hotspot is a cheap Android phone + a powerbank. And a cool place, because running both 5G and Hotspot makes the device hot. Really hot.
Yes.. the 5G + Wi-Fi hotspot on a smartphone + continuous usage + moving constantly could be a dangerous combination.
4G JioFi would be a much more reliable and safer option. It is quite easy to install third-party firmware too.
Which is basically rolling your own. I was referring to a router with OOTB 5g functionality.
Those 5G modules are very costly. The ones selling in Ali appear to be engineering samples.
