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)
This paper presents the energy performance of a new radio access technology (RAT) component in 5G, here denoted as 5G-NX. The 5G-NX RAT encompasses massive beamforming and an ultra-lean design as two of its key technology components. The user throughput, resource utilization of the cells and daily average area power consumption are evaluated by means of(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)
The standardization of 5G New Radio (NR) has started and addresses a wide range of use-cases. The 5G application demands include among others, very high data rates, support for huge number of low-power devices and mission critical communication. NR design supports operation in both traditional licensed frequency spectrum bands as well as unlicensed(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)
