# Wired conversion (Ethernet, corded peripherals)

> Replacing radios with cable is the only measure that removes an RF source instead of attenuating it, and it is usually cheaper than shielding the room the source sits in.

## Key values

- **Form:** filter
- **Targets:** radiofrequency
- **Grounding required:** No

## Failure modes

- Devices often keep their radios on after being cabled; the radio must be explicitly disabled
- Power-line networking adapters replace an RF source with a conducted-harmonics source
- Unshielded patch cable near a bed can carry common-mode noise; use shielded cable and a single bonding point
