Wireless Site Survey

Question

As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which two areas is the engineer most likely to find sources of 2.4 GHz and 5 GHz RF noise? (Choose two.)

Options

  • Amagnetic resonance imaging
  • Bkitchen
  • CGamma Knife radiation treatment
  • DX-ray radiography
  • Epatient room

Explanation

MRI scans emit at a frequency of 1MHz-300MHz, which is below the frequency of Wi-Fi (2.4GHz and 5GHz). Gamma rays (Exahertz) and X-rays (Petahertz) are happening at frequencies much higher than RF as well. Kitchens can be source of 2.4GHz interference with microwave ovens. People have mobile devices in patient rooms such as tablets and cellphones which adds to the rf noise on 2.4Ghz and 5Ghz.
