What is it about?
For wireless experiments, comparison of native performance of transceivers has been difficult because frequency, modulation, antenna gain, data rate and communication distance are all different. By normalizing these different parameters, we have successfully compared native performances of transceivers. By comparing our 300-GHz CMOS transmitter with other 300-GHz transceivers with this method, it is shown that the performance of the former device is comparable to the other conventional devices.

Why is it important?
We have clarified a figure of merit (FoM) determined from trade-off between communication distance and data rate. This makes it possible to compare native performance of transceivers, which has not been easy to compare conventionally. Furthermore, it is shown that the performance of the CMOS transmitter, which seemed inferior in performance to a transmitters made of conventional compound semiconductor, is comparable to the others.
Perspectives
In wireless experiments, the length of the communication distance was sometimes claimed in conventional reports. However, because the communication distance varies depending on the communication parameters, it does not directly represent native performances of transceivers. We believe that our proposal will be an essential tool for comparing various wireless experiment results on the same field.
