Keysight Technologies Korea country manager Junho Choi said on Thursday that the company has over 50 years of research in mmWave.
Research in mmWave when the company was part of Hewlett-Packard and the firm’s headquarters of Santa Rosa is considered the Mecca of mmWave, Choi said on the online conference.
MmWave were previously used mostly for the military but is expected to be used in 5G networks.
Military is Keysight’s basic area of business and other companies lack behind in knowhow on mmWave as they haven’t been working until recently.
30GHz spectrum has a wave length of 10mm. The higher the spectrum, the shorter the wavelength. From 30GHz to 300GHz have mmWave.
5G networks use 28GHz, which strictly speaking isn’t mmWave but frequency range 2 (FR2), which is from 24GHz to 100GHz.
The currently commercialized 5G network is FR1 and is using 4G technologies together, Choi said. The main 5G services will those in the FR2 range such as 29GHz and 39GHz.
FR2 services will began in earnest starting in 2021. FR1 refers to sub-6GHz spectrum.
It is impossible to test mmWave with a cable and over the air (OTA) method is required.
OTA was difficult before but Keysight has compact antenna test range (CART) that allows for measurement in the chamber. The company had knowhows from the military market, the company said.
Keysight launched the mmWave simulation software Pathwave Design 2021 earlier this year. Simulation testing is expected to increase as mmWave makes testing more difficult, the company said.
