Fundamentals of Microwave, mmWave, and Massive MIMO

5-day training event
6100-3110

Microwave, mmWave, and Massive MIMO fundamentals center on how electromagnetic waves are generated, propagated, and manipulated to maximize wireless capacity and coverage: microwave frequencies (roughly 1–30 GHz) offer robust propagation and penetration for wide-area and backhaul links; mmWave bands (roughly 24–100 GHz) provide very large contiguous bandwidths enabling multi-gigabit throughput but require highly directional antennas and suffer greater path loss and susceptibility to blockage; Massive MIMO leverages large antenna arrays and advanced beamforming algorithms to spatially multiplex many users simultaneously, increasing spectral efficiency while mitigating interference and compensating for higher-frequency impairments through beam steering, channel estimation, and precoding; together these technologies demand careful system design—including antenna array geometry, RF front-end linearity, channel modeling, and link-adaptation strategies—to balance trade-offs among coverage, capacity, latency, and hardware complexity in next-generation wireless networks.
