BACKGROUND Use of mobile phones has rapidly risen among adolescents despite a lack of scientific certainty on their health risks. Risk perception is an important determinant of behavior, and studies on adolescents' risk perceptions of mobile phones or base stations are very scarce. This study aims to evaluate high school students' risk perceptions on mobile phones and base stations, their trust...

Individuals who report sensitivity to electromagnetic fields often report cognitive impairments that they believe are due to exposure to mobile phone technology. Previous research in this area has revealed mixed results, however, with the majority of research only testing control individuals. Two studies using control and self-reported sensitive participants found inconsistent effects of mobile...

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption. Therefore, this paper investigates changes in the instantaneous power consumption of GSM (Global System...

To allow for wireless communications among a specific geographic area, base stations of communication network must be deployed to allow sufficient radio coverage to every mobile users. The base stations, successively, must be linked to a central hub called the MSC (mobile switching centre). The mobile switching centre allow connectivity among the PSTN (public switched telephone network) and the...

One of the main features of IEEE 802.16m is the relay transmission which could not only extend the service coverage, but also improve the quality-of-service (QoS) to the mobile stations. In this paper, we consider the cooperation among relay stations and mobile stations to improve the performance of relay transmission in IEEE 802.16m network. In this case, the relay stations and mobile stations...

800x600 as a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. today laptops are a great tool for education and learning, work and personal multimedia. millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). over the past several...

BACKGROUND In recent years, by tremendous use of mobile phone telecommunication, a growing concern about the possible health hazards has increased greatly among public and scientists. The mobile phone exposure has been shown to have many effects upon the immune functions, stimulating hormones, mammalian brain, sperm motility and morphology, and neurological pathologies syndrome. The aim of this...
