As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which three areas is the engineer most likely expect to find sources of 2.4 GHz and 5 GHz RF noise? (Choose three.)
A. emergency room
B. magnetic resonance imaging
C. laboratory
D. X-ray radiography
E. Gamma Knife radiation treatment
F. kitchen
Do not understand this one. I have done audits of many hospitals and Emergency/Labratory areas are not acceptional Layer 1 interferers. However X-Ray, MRI and Nuclear medicin areas are sheilded and often Wifi is banned in those areas. So I see no real good answer here and can find no colaboration online.
MRI, X-Ray, and Gamma frequency have more high frequency than the radio. It will not make the radio signal to interference with those frequency. And why MRI, X-Ray and gamma must shielded, it’s because if exposure to the outside room it will make the other person exposed by those harmful radiated wave.
