Which technology enables multiple antennas to transmit/receive simultaneously for higher data rates in 4G/5G?

  1. OFDM
  2. MIMO
  3. CDMA
  4. TDMA

Answer: MIMO

MIMO (Multiple Input Multiple Output) uses multiple antennas at transmitter and receiver to send/receive multiple data streams simultaneously over same frequency. Increases spectral efficiency, data rates, and link reliability. Evolution: SU-MIMO (single user) to MU-MIMO (multi-user). Foundational for 4G LTE-Advanced and 5G NR performance.
