In the Filed of IT and Mobile Communications, there is huge demand of growing Data Rates and low latency in Communication Networks. In ref to the on going Research in the Next Generation Networks and practical field Experiences, I have analyzed Several Techniques, made own point view and proposed Recommendations that in which aspects and dimensions we can more focus to obtain the desired results for enhancing air-interface performance in future 6G networks. It built the analysis base of cellular evolution from 2G to 5G to identify current microwave transmission limitations and the upcoming performance demands of 6G, including high data rates, low latency and increased capacity.
