Abbas School of Electrical and Electronic Engineering. First, worldwide state-of-the-art measurement solutions are presented. Selected Active Projects. VHF (30 MHz to 100 MHz) With low power and small antennas, primarily for local use. Absence of any mmWave radio platforms with phased arrays in the networking community.
