Which of the following is NOT a reason for low signal strength?

• A. Increased transmission power
• B. Obstructions between device and source
• C. Distance from the source
• D. Interference from other devices

Answer: (A)

Increased transmission power is associated with improving signal strength rather than contributing to a reduction in it. When the transmission power is increased, a device can transmit its signal over greater distances and potentially penetrate through obstructions more effectively, thereby enhancing the overall signal strength. On the other hand, obstructions such as walls or furniture can diminish the signal as they absorb or reflect the radio waves. Similarly, as the distance from the source increases, the signal weakens due to the natural attenuation of the waves. Interference caused by other electronic devices can also disrupt the signal, causing it to be received more weakly. These factors are known to lead to low signal strength, making increased transmission power the only option that does not apply to this scenario.
