Key Points
- Millimeter wave (mm-wave) band ranges from 30GHz to 300GHz
- capability to support multi-Gbps throughput
- many antennas elements in a single array
- decreased latency due to latger bandwidth
As millimeter wave operates at exmtremely high frequency. Higher-frequency transmissions have more bandwidth than lower-frequency transmissions. Millimeter-wave - an integral part of future wireless communication. High throughput & low latency of millimter wave communication is good for real time application.
Challenges
- poor link budget
- significant path loss
- penetration and reflection loss
- Doppler spread due to mobility
