mmWave propagation challenges
§ Atmospheric gas
attenuation
• Water vapour
• Oxygen
§ Rain attenuation
§ Non-line-of-sight
• Foliage blocking
• Diffraction/fading
• Scattering

Why mmWave?
Everything gets more difficult above 24GHz:
§ Semiconductor process capabilities decline
§ Design difficulty increases
§ Propagation losses increase and non-line-of-sight
communications becomes a real challenge
§ System designs to address the above become more
challenging
So why choose to use mmWave frequencies?
§ Bandwidth: the best way to achieve the peak data rates of up to
10Gbps and wider channel bandwidths to increase the channel
capacity
