Did you know? 5G spectrum directly affects its future development vision [Copy link]

The 5G era is coming. Are you looking forward to what 5G will bring like me - faster mobile networks and better mobile life?

But do you know? In the field of mobile communications, spectrum resources are the core resources that drive industrial development and are the basis for carrying wireless services. Therefore, the -6GHz band, which can take into account the coverage advantages of low frequencies and the capacity advantages of high frequencies , is crucial for fully unleashing the potential of 5G in the next decade .

Therefore, last month , GSMA once again called on countries to use 6GHz as licensed spectrum, and warned that if governments fail to use 6GHz as licensed spectrum, it will jeopardize the development prospects of 5G around the world.

How important is the 6GHz band to 5G ?

6GHz is the ideal mid-band for 5G

The 6GHz frequency band ranges from 5.925 to 7.125GHz , which is the same as the current mainstream 5G frequency band of 3.3 to 4.2GHz . It has a continuous large bandwidth of 1200MHz , which can perfectly adapt to the 5G 100MHz channel bandwidth and carrier aggregation technology, greatly improving the capacity of future 5G systems. In terms of coverage, although the 6GHz is weaker than the lower 3.5GHz mid-band in terms of wireless propagation characteristics , the relevant simulation and analysis results show that if the continuous development of related technologies such as propagation loss compensation is taken into account, the coverage capability of 6GHz can be close to that of the 3.5/3.8GHz band. Therefore, the 6GHz band has both coverage and capacity advantages, and is an ideal mid-band for 5G , which is conducive to the continuous construction of a continuous coverage, large-bandwidth 5G network to meet the growing network capacity requirements.

6GHz frequency band helps narrow the digital divide

For some countries and regions where fiber-optic broadband has not yet been popularized, the coverage and capacity advantages of the 6GHz frequency band are very suitable for providing 5G fixed wireless services in rural areas, thereby replacing higher-cost fiber-optic access methods, which is conducive to the rapid popularization of broadband networks and narrowing the urban-rural digital divide.

3GPP global unified standards are more conducive to unleashing the potential of the 6GHz frequency band

From the perspective of the industry ecosystem, 3GPP is currently researching 5G standards for the 6GHz frequency band , and major manufacturers have also conducted a lot of research and development and testing on 5G technologies working at 6GHz . 6GHz is used for licensed spectrum, and based on more advanced 3GPP technology and the deployment and operation capabilities of operators, it can also better improve spectrum utilization efficiency and minimize potential frequency interference.

In short, 6GHz is an ideal 5G mid-frequency band, which can realize 5G universal large-bandwidth services at a lower cost per bit , enable the continued prosperity and growth of 5G emerging applications, and accelerate the digital transformation of the entire society.
