The South Korean electronics giant expects 6G would need to be designed to utilize up to the 3THz band and predicts the technology should be capable of supporting up to 10 million devices per square kilometer due to the explosive growth in connected devices.
Whereas 5G requirements mainly focused on performance aspects, Samsung defines three categories of requirements that have to be met to realize 6G services – performance, architectural and trustworthiness requirements. Examples of 6G performance requirements are a peak data rate of 1,000 Gbps (gigabits per second) and air latency less than 100 microseconds (?s), 50 times the peak data rate and one-tenth the latency of 5G. A comparison of key performance requirements between 6G and 5G is shown in the diagram below.
Of course, 6G is still far into the future. Samsung predicts 6G will be ready for commercialization by 2028, with mass adoption somewhere around 2030. More details at Samsung.
