I understand your point about USB tethering, but using WiFi tethering is simpler and delivers comparable outcomes.
I notice you're concerned about WiFi radiation. Would you like tips on reducing exposure or information about its effects?
Microwaves are non-ionizing, yes, but they still can't strip electrons from atoms. Their harm comes from rapidly vibrating water molecules, generating heat. This is the principle behind a home microwave: water in food heats up, transferring warmth to the surrounding food. If exposed, you'd experience similar effects—cooking from within due to your body's high water content. Regarding Wi-Fi or other radio waves, they usually lack enough power and have different frequencies to cause harm. The FCC limits Wi-Fi to just 1 watt, which is minimal, while most microwaves operate at around 1000 watts. Also, the frequencies differ, so they don't heat water effectively. In short, the main concern is with microwaves, not typical wireless signals.
I believe a mobile internet hub is the most effective solution. You connect a SIM card—either your current one or a new one—to the device, enabling it to access the mobile network and function as a router. Some models offer Wi-Fi connectivity, which you can utilize through your phone’s built-in hotspot, though performance may be reduced. Others provide additional ports like Ethernet or USB. This approach isn’t the most affordable option, but it delivers reliable functionality.
The only solution is using WiFi. Your cell phones emit more radiation than typical wireless routers. The best option is to enable the hotspot function on your phone. Alternatively, look for a router that supports USB 4G connections. You can also use USB to Ethernet adapters. If you don’t plan to rely on the phone’s hotspot, you’ll need a router.
