NEW QUESTION # 29
What is the attenuation value of a human body on a wireless signal?
- A. 6 dB
- B. 12 dB
- C. 4 dB
- D. 3 dB
Answer: D
Explanation:
Signal Attenuation
Signal attenuation or signal loss occurs even as the signal passes through air. The loss of signal strength is more pronounced as the signal passes through different objects. A transmit power of 20 mW is equivalent to 13 dBm. Therefore, if the transmitted power at the entry point of a plasterboard wall is at 13 dBm, the signal strength is reduced to 10 dBm when exiting that wall. This table shows the likely loss in signal strength caused by various types of objects.
Signal Attenuation Caused By Various Types of Objects
Object in Signal Path
Signal Attenuation through Object
Plasterboard wall
3 dB
Glass wall with metal frame
6 dB
Cinder block wall
4 dB
Office window
3 dB
Metal door
6 dB
Metal door in brick wall
12 dB
Human body

Each site surveyed has different levels of multipath distortion, signal loses, and signal noise. Hospitals are typically the most challenging environment to survey due to high multipath distortion, signal losses and signal noise. Hospitals take longer to survey, require a denser population of access points, and require higher performance standards. Manufacturing and shop floors are the next hardest to survey. These sites generally have metal siding and many metal objects on the floor, which result in reflected signals that recreate multipath distortion. Office buildings and hospitality sites generally have high signal attenuation but a lesser degree of multipath distortion.
