—With the continuous growth in connected devices and the need for larger bandwidth channels and greater data speeds, operating at high frequencies can be advantageous for future mobile communications in general, and for 5G-networks in particular. In this paper, the indoor coverage at different high frequencies, namely 10, 30 and 60 GHz has been analyzed in(More)
—To meet future demands on user experience and traffic volumes, mobile networks need to evolve towards providing higher capacities and data rates. In this paper we investigate the feasibility of incorporating higher frequency bands (15 GHz) and beamforming to support this evolution. We see that using user-specific beamforming, the challenging propagation(More)
In electrical systems, the battery, which is a device converting the stored energy as chemical to electrical one, is composed of one or more electrochemical cells. Nickel Cadmium batteries (Ni-Cd) are used in different applications as emergency lighting, mobile phones and others. The "high surge current" obtained in these batteries is depending on the(More)
