• NFC

As a network engineer, Matthew has installed a wireless connection in a newly constructed office floor for Yuvi Mediaworks. The office of the managing director of Yuvi Mediaworks is located at the end of the hallway, and he has raised a complaint about slow data transmission and occasional dropped connections. According to Matthew, the issue should be related to obstacles blocking the signal's passage. Analyze which of the following phenomena must be used to ideally describe this scenario.

• Attenuation

• Fading

• Interference

• Refraction

Name the phenomenon where a wireless signal is split into secondary waves, when it encounters an obstruction?

• Reflection

• Diffraction

• Refraction

• Scattering
