List some of the advantages and disadvantages of using mmWave in telecommunications?
Advantages of mmWave
1.The extremely wide bandwidth and narrow beam of millimeter wave communication.
Millimeter wave frequency range is 26.5～300GHz, and the bandwidth is as high as 273.5GHz, which is more than 10 times the full bandwidth from DC to microwave.
2.Strong mmWave detection capability and good security.
Broadband and broad-spectrum capabilities can be used to suppress multipath effects and clutter echoes. There are a large number of frequencies available to effectively eliminate mutual interference.
3.High millimeter wave transmission quality, small component size and all-weather communication
Because there are basically no interference sources in high-frequency millimeter wave communications, and the electromagnetic spectrum is extremely clean, the millimeter wave channel is very stable and reliable, and its bit error rate can be maintained at the order of 10-12 for a long time, which is comparable to the transmission quality of optical cables.
4.Drastic improvements in network performance represent the collective advantage of mmWave 5G
When compared to sub-6 GHz networks, as well as 4G LTE and LTE Advanced networks, users connected to networks running on the millimeter wave specification will experience faster data transmission speeds, higher bandwidth, and dramatic reductions in
network latency.
Disadvantages of mmWave
1.Devices equipped to use the millimeter frequency specification would also suffer from intensive power consumption, especially when connected to the fifth-generation network
2.Deploying mmWave 5G networks is fundamentally more expensive than deploying 5G networks based on the sub-6 GHz specification because of the need to place several smaller cells in strategic locations to ensure maximum coverage.
3.Compatibility is another drawback
