3、e non-standalone version of the fifth wave of wireless radio communications technology.5G radio access networks(5G RAN)saw the introduction of new radio transmission technology,the licensing of new higher-frequency bands in the electromagnetic spectrum,and the introduction of new hardware technology

4、 such as massive MIMO antennas to improve spectrum efficiency and performance.This phased approach to 5G was a necessity born of the fact that 5G Core(5GC)network functionality was still being defined.However,the concept of introducing 5G network slicing had already set the seeds of expectation as a

5、 route to new revenue opportunities:network slicing,it was argued,could catalyze extensive business diversification.And as our recent report Telco revenue growth:taking it to the next level shows,core connectivity business for CSPs has not seen significant growth for more than a decade,making servic

6、e models beyond simply connectivity imperative.But CSPs face some significant challenges when transitioning to 5GC.These range from the technical complexity of developing cloud-native infrastructure and implementing the 5G Core,to having sufficient 5G RAN coverage and the availability of 5G standalo
