Background Epilepsy is a major neurological disorder that affects approximately 65 million people worldwide. Globally, the burden of epilepsy is not evenly distributed, with more than 80% of sufferers residing in low- and middle-income countries. This study estimates the burden of epilepsy in mainland China from 1990 to 2015 and explores the variations of burden by age and gender. Methods We ...

Energy Efficiency (EE) of base stations (BSs) in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall environment effects and economic issues for wireless network operators. In this paper, we highly focus on the EE evaluation of LTE BSs. Then, the parameters that are affecting the EE and the coverage area of LTE BS in d...

MmWave communications are expected to play a major role in the Fifth generation of mobile networks. They offer a potential multi-gigabit throughput and an ultra-low radio latency, but at the same time suffer from high isotropic pathloss, and a coverage area much smaller than the one of LTE macrocells. In order to address these issues, highly directional beamforming and a very high-density deplo...

MIPAS is a limb viewing fourier transform spectrometer operating in the infra-red. It scans the tangent altitude range 6-68 km at a vertical resolution of approximately 3km. CO has various natural and anthropogenic sources including forest fires and industry. In the troposphere, CO is the main sink of the principal oxidising agent the hydroxyl radical and so reduces its capacity for the removal...

We address a unique security vulnerability in long term evolution (LTE) advanced and high speed packet access (HSPA+) wireless networks due to carrier/channel bonding. This vulnerability is shown to result in various amounts of service disruption based on the radio network parameters and the user locations. Typically, channel bonding have been perceived as a means to enhance the bandwidth and t...

This paper intends to look deeper into finding an ideal mobile broadband solution. Special stress has been put in the South Asian region through some comparative analysis. Proving their competency in numerous aspects, WiMAX and LTE already have already made a strong position in telecommunication industry. Both WiMAX and LTE are 4G technologies designed to move data rather than voice having IP n...

Abstract Utilization of unlicensed spectrum under licensed assisted access ensuring fair co-existence with Wi-Fi networks is a good solution to address immense usage mobile data. Radio communication operation LTE in frequency band referred as LTE-unlicensed (LTE-U) or LTE-licensed access. In this paper, we consider HGNW which coverage area Wireless-Fidelity (Wi-Fi)’s Access Point integrated wit...

The main objective of this paper is to simulate the throughput of the new generation of mobile networks and check if the results are consistent with theoretical values. The LTE network and its evolution, LTE-Advanced, were studied. Using two different simulators, the parameters that had a greater impact on maximum throughput were studied and the conclusion was that these parameters are the Band...

LTE (Long Term Evolution) networks have been introduced in 3GPP (Third Generation Partnership Project) release 8 specifications, with an objective of high-data-rate, lowlatency and packet-optimized radio access technology. The QoS for multimedia services are defined in LTE specification. However the scheduling algorithms for supporting real time and non-real time application services are not sp...

In order to minimize the amount of energy consumption at the user equipment (UE) level, the 3rd Generation Partnership Project (3GPP) presented in the Long Term Evolution (LTE) an approach called discontinuous reception (DRX). Nevertheless, existing models for the LTE DRX and their extension to scenarios that support carrier aggregation (CA) and multi-stream carrier aggregation (MSCA) have seve...
