EMF Tips

An external wired keyboard lets you move the laptop away from your hands and forearms. Distance from the logic board and battery is what changes.

A hard surface between you and the laptop, like a desk or stand, mainly addresses heat and closeness. The radio signal itself is not the strong factor here.

Neighbors’ routers can add a low level of RF indoors, especially in apartments. Checking how strong they really are tells you if shielding is worth the effort.

The router can sit anywhere, so place it where nobody sleeps or sits for long. A cable carries the connection the last few steps to the devices you use.

A plug-in mechanical timer cuts router power on a schedule, so night shutoff does not depend on memory. It reliably removes the source for set hours.

Grounding a router concerns the electric field around its power cord, not its WiFi signal. Whether it helps depends on the plug and what the outlet supports.

WiFi and cellular data are both radio, and which is lower depends on distance. A close router usually asks less of the phone than reaching a distant tower.

Tethering a laptop to a phone over USB replaces the WiFi hotspot link with a cable. A long cable also lets the phone sit across the room from you.

Voicemail forwarding lets a phone stay in airplane mode for stretches while callers can still leave messages. The radio is off for as long as you choose.

With VoIP, a corded phone can serve as the home number over cable and the internet. That replaces the cordless base and handset radios with a wire.

Swapping a cordless handset for a corded phone removes the base station, which transmits continuously in stand-by. It also ends the radio link to the handset.

A router guard is a metal mesh enclosure that reflects part of the router’s output. It suits homes where the router has to keep running for WiFi-only devices.
