Can wireless networking devices affect pacemakers or other medical devices?
There is no evidence that the radio waves in the band used by wireless networking devices (2.4 GH range) cause any health risk. In addition, wireless networking devices work at very low power levels (30 – 100 Mw), the same level as cordless phones. By contrast, a typical hand held-cell phone has a RF power output of 600mW or almost 20 times more output power than most wireless networking devices.
