Millimeter Wave Massive MIMO Beamforming with Hybrid Precoding
Quick fact
Millimeter wave signals are extremely fragile, losing energy over distance, but with massive antenna arrays, the power can be focused like a flashlight instead of spreading like a light bulb, delivering dramatic gains in signal strength and data rates.
Why this is interesting
Your phone already uses multiple antennas to speed up data, but at millimeter wave frequencies you might need 64 of them—so why doesn't your phone have 64 separate radios? The answer lies in a clever blend of two techniques.
