Shielding & remediation

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.

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

Related records

  • Wi-Fi router (2.4 / 5 / 6 GHz)

    A consumer access point radiating roughly 100 mW EIRP per band, giving about 8,000 µW/m² at 1 m and 80 µW/m² at 10 m in free space.

    Sources & emitters

  • Wi-Fi security camera and video doorbell

    Continuously streaming 100 mW transmitters, usually mounted at head height near doors and windows, giving about 8,000 µW/m² at 1 m.
