Explanation
In a hospital, Layer 1 RF interferers operating in the 2.4 GHz and 5 GHz ISM bands are most likely found in: (A) Emergency rooms - contain numerous portable electronic devices, wireless monitors, defibrillators, and other medical equipment that can emit broadband RF noise; (C) Laboratories - house a wide variety of scientific instruments, wireless sensors, and testing equipment that generate RF emissions; (F) Kitchens - microwave ovens are classic 2.4 GHz interferers as they operate at ~2.45 GHz and leak RF energy that directly overlaps Wi-Fi channels. MRI machines operate at very low RF frequencies (e.g., ~64 MHz for 1.5T) and are housed in RF-shielded rooms. X-ray and Gamma Knife equipment use ionizing radiation (X-rays and gamma rays), not 2.4/5 GHz RF, so they are not relevant Layer 1 Wi-Fi interferers.
