5G, to realize the interconnection of all things.
5G is the fifth-generation mobile communication standard, formulated by the International Telecommunication Union (ITU). The official name of 5G is IMT-2020.
The WRC19 meeting discussed and determined that the spectrum resources of 24.25 GHz-27.5 GHz, 37 GHz-43.5 GHz, 66 GHz-71 GHz, in total 14.75 GHz bandwidth will be used worldwide to the future development of 5G and the International Mobile Telecommunications System (IMT); In 5G, two regions of spectrum resources FR1 and FR2 are allocated. (FR: Frequency Range). FR2 frequency band, its wavelength range is between 1 mm and 10 mm, we call this frequency band millimeter wave.
According to the characteristics of electromagnetic waves, the propagation of electromagnetic waves does not require medium. The same frequency electromagnetic waves have different speeds in different media. When electromagnetic waves of different frequencies propagate in the same medium, the higher the frequency, the higher the refractive index, the lower the speed, the weaker the penetration ability. Therefore, for the millimeter wave in the FR2 band, the signal loss is much larger than that in the Sub-6G band of FR1 band. It’s also highly susceptible to rainy weather.
With the development of high-capacity, high-speed, and low-latency services, the communication frequency band is bound to extend in the direction of millimeter waves.The basic architecture of 5G mobile communication will be a combination of low frequency band (Sub6G) + millimeter wave band (mM).
The signal coverage of popular scenarios with concentrated crowds, customized private network services and the application requirements of fixed access put forward flexible, economical and integrated requirements for millimeter-wave deployment scenarios and deployment scales.
Focusimple digs deep into industry pain points, relying on its own advantages in R&D and production integration, further focusing on the business fields needs and scenarios needs，launching a high-bandwidth, low-loss and stable RF signal connection application integration solution that fits 5G networking to accelerate the promotion of 5G millimeter waves Industrial chain development.
