This paper presents a performance evaluation of 60 GHz high-speed radio systems under an application scenario related to a medical operation. The evaluation is based on the following specifications: IEEE 802.15.3c and IEEE 802.11ad, which have been designed to provide data rates of multi-Gbps at physical layer. First, by using measured power delay profiles (PDPs) in hospital environments, both inter-symbol-interference (ISI) and channel capacity are calculated. Then, system simulations are carried out in order to show achievable throughputs. The results reveal that OFDM systems provide the required throughput for the application scenario in all the measured PDPs. On the other hand, the single carrier (SC) systems without any equalization are limited to 85 % of the measured PDPs where the required throughput is achieved. Also, it is shown that the calculated channel capacity for each measured PDP reveals the similar trend with the available throughputs obtained from the system simulations.
