Nowadays the spectrum regulations landscape is changing towards more flexible spectrum management schemes, such trends are expected to make additional spectrum resources available and lowers the spectrum access hurdles. In this paper, different spectrum aggregation scenarios have been compared focusing on the tradeoff between the total cost of ownership and the targeted QoS under different market...
Mobile operators nowadays tend to deploy dense heterogeneous layers of 3G and 4G networks in outdoor and indoor environments by adding more macrocells and small cells (e.g. microcells, picocells and femtocells) in response to the increasing demand for coverage and capacity. Another main driver and enabler behind this tendency is the phenomenon that around 80% of power consumption in mobile communication...
As the main emitter of CO2, power sector is becoming the primary focus for carbon reduction. However, existing researches mainly focus on power generation side, for example, renewable energies and nuclear, the role grid plays is often ignored. This paper assesses carbon reduction impact of cross-region power transmission in China by establishing a multiregion Integrated Resource Strategic Planning...
The deployment of low cost and low power base stations has been recognized in recent years as a promising cost-efficient solution and energy-efficient strategy. In this paper the femtocell and macrocell deployment options have been compared in the context of indoor mobile broadband deployment, with focus on the effect of different backhauling solutions in power consumption and the total deployment...
We have compared the total cost of an innovative elastic network with respect to the conventional WDM ones operating in realistic network scenarios. The results give an insight of the cost benefits that can be obtained with an elastic OFDM-based network for the operation of future optical transport networks with different protection schemes.
This paper is aimed at calculating the power demand of a combined irrigation and domestic load in Toshka area, Toshka, Egypt. The pipe line system for irrigation is designed. An economic feasibility study has been made for hybrid PV-wind system to power this combined load. Sizing of the hybrid system components was investigated using MATLAB Code and HOMER Package. The energy cost values of the hybrid...
An aging population, coupled with choices on diet and lifestyle, is causing an increased demand for portable, wearable, and implantable medical devices that enable chronic disease management and wellness assessment. Battery life specifications drive the power consumption requirements of integrated circuits in these devices. Microcontrollers provide the right combination of programmability, cost, performance,...
3-D integration technology is emerging as an attractive alternative to increase the transistor count for future chips. The majority of the existing 3-D integrated circuit (IC) research is focused on the performance, power, density, and heterogeneous integration benefits offered by 3-D integration. All such advantages, however, ultimately have to translate into cost evaluation when a design strategy...
