Which wireless communication problem is caused by electromagnetic waves?
- Fading
- Attenuation
- Interference
- Diffraction
Explanation:
Because the air is shared by all transmitters, transmissions by any device at the same frequency as an access point’s radio can cause interference. Because 802.11 wireless networks operate in unlicensed bands used by many technologies, such as microwave ovens, video surveillance cameras, cordless phones, they are subject to interference.
