Summary of HOW CAN 5G MMWAVE BENEFIT IOT APPLICATIONS
The millimeter wave (mmWave) is the 30–300 GHz extremely high frequency band used by 5G NR as FR2. Compared with sub-6 GHz, mmWave offers much wider bandwidth and abundant spectrum resources, enabling significantly higher data rates and lower latency for 5G. Its larger available spectrum and higher frequencies overcome the crowded sub-6 GHz bands, allowing many more simultaneous high-speed transmissions.
Parts used in the5G mmWave:
- Millimeter wave spectrum (30–300 GHz)
- 5G NR FR2 frequency band
- Sub-6 GHz frequency band (FR1) for comparison
- Spectrum resources (general term)
- Bandwidth (as a capacity component)
What is 5G mmWave
The millimeter wave (MM wave), also known as the millimeter band, is a spectrum band with wavelength ranging from 30 GHz to 300 GHz, which the International Telecommunication Union also refers to as the extremely high frequency (EHF) band.
According to 3GPP, 5G NR (New Radio) mainly uses two frequency bands: FR1, also called the sub-6GHz frequency band, and FR2, which is mmWave. 5G can have several times or even dozens of times the network speed of 4G LTE thanks to the utilization of mmWave.
Advantages of 5G mmWave
You might ask why 5G needs mmWave and why mmWave means higher network speed rate. There are two fundamental reasons: High bandwidth, and abundant spectrum resources.
- High bandwidth
Compared with sub-6GHz, the millimeter wave frequency band can provide higher bandwidth. The wider the bandwidth, the higher speed rate that can be supported. Take trucking as an example. The transmission of data is like the transportation of goods between two stations. The goods on the truck are the data that needs to be transmitted. The road between the starting point and the ending point is the electromagnetic wave we use.
In order to quickly deliver all the goods to the other end, we can increase the lanes to increase the number of trucks that can travel at one time, which is to increase the bandwidth. The more lanes, the more trucks can drive through in a unit time. In other words, the higher the bandwidth, the more data can be received in a unit time, which is undoubtedly a faster network speed as well as low latency.
- Rich resources
As the wireless communication technology developing from generation 1 to generation 5, the frequency of electromagnetic wave they used is getting higher and higher. The sub-6GHz frequency band is already very crowded, with plenty of wireless communication services interfering with each other.

- What frequency range does mmWave cover?
The millimeter wave band covers 30 GHz to 300 GHz according to the article. - Which 5G NR frequency band is mmWave?
mmWave corresponds to FR2 in 5G NR. - Why does 5G use mmWave?
Because mmWave provides higher bandwidth and abundant spectrum resources, enabling much faster network speeds and lower latency. - How does higher bandwidth lead to faster network speeds?
Higher bandwidth is like adding lanes to a road, allowing more data to be transmitted simultaneously, which increases speed and reduces latency. - How does mmWave compare to sub-6 GHz?
mmWave offers wider bandwidth and more spectrum resources, while sub-6 GHz is more crowded with many interfering services. - What is the other main 5G frequency band besides mmWave?
The other main 5G frequency band is FR1, also called the sub-6 GHz band.
