Unicom accelerates 5g co construction and sharing: or will expand to 2.1GHz frequency band

Based on various considerations, China Unicom and China Telecom announced to build and share 5g. According to the content of the 5g Network Co Construction and sharing framework cooperation agreement reached by both parties, both parties will build and share the 3.5GHz 200MHz 5g frequency band (3400mhz-3600mhz) nationwide.

Ma Hongbing revealed that in addition to 3.5GHz, China Unicom and China Telecom also intend to share the 2.1GHz frequency, "this can achieve high, medium and low-frequency coordination, provide better coverage, and reduce the number and cost of coverage with low-frequency in some wide areas, which is also our consideration." 2.1GHz is now mainly used in 4G network. With the gradual promotion of 5g network, spectrum re cultivation will be an inevitable choice.

It should be noted that from the current progress of the industrial chain, the system equipment supporting 200MHz has gradually matured, but it is not fully in place on the terminal side. China Unicom and China Telecom are promoting the establishment of relevant standards in the standards organization. In terms of networking mode, China Unicom and China Telecom have also reached a consensus to work together to accelerate the maturity of SA. In SA mode, the network structure will be more concise, and also has the ability of end-to-end network slicing, which can better adapt to 2B business development.
