Fig. 1From: Machine type communications: key drivers and enablers towards the 6G eraMTC requirements and service classes towards 6G. Evolution of MTC requirements from the 5G triangle to the 6G hexagon (top), potential MTC specific service classes in 6G (bottom). The qualitative performance indicators of the potential new MTC services classes in 6G are collected from the different numbers predicted in various initial 6G vision papers (e.g., [13, 14, 18, 23])Back to article page
