QuestionQ4

Mobile backhaul architecture and technologies

Which technology uses two or three antennas to receive (input) a signal and two or three radios to transmit (output), along with special signal processing to improve range, reliability, and throughput?

  • A HSPA
  • B CDMA
  • C LTE
  • D MIMO
Explanation

MIMO (multiple-input multiple-output) uses multiple antenna/radio paths and signal processing techniques such as diversity, array gain, and spatial multiplexing. These improve signal reliability and range while increasing throughput compared with a single-antenna system.
