Background: Distracted walking is a major cause of pedestrian fatalities. Along with the expansion and popularity of mobile phones, their impacts on pedestrian safety, especially when crossing urban intersections have attracted a lot of attention. The purpose of this study is to evaluate the effects of mobile-phone use on pedestrians’ crossing behavior when passing signalized intersections. Ma...

The deployment of a miniature mobile-phone base station or small cell in a train car significantly improves the coverage and the capacity of a mobile network service on the train. However, the impact of the small cell on the passengers' exposure to radio-frequency electromagnetic fields (RF-EMF) is unknown. In this study, we assessed experimentally the RF-EMF exposure of a mobile-phone user who...

The cell phone is one of the potential Information Communication Technologies (ICTs) in agricultural development especially in developing countries like Bangladesh. Thus, this paper deals with the farmers’ communication with the agricultural extension agents using mobile phone. The study was conducted in Mymensingh District in Bangladesh. Data were collected from a sample of 110 farmers while b...

The prediction of the handover in mobile wireless networks is an easy way of optimal disposing with radio resources and efficient increase of quality of services. The prediction can be based on the several approaches. This paper is focused on the monitoring of the history of serving and target base stations while the handover is executed. The information about previous handovers of all users ar...

We address the problem of detecting a rogue base station (BS) in WiMax/802.16 wireless access networks. A rogue BS is a malicious station that impersonates a legitimate access point (AP). The rogue BS attack represents a major denial-of-service threat against wireless networks. Our approach is based on the observation that inconsistencies in the signal strength reports received by the mobile st...

Abstract In order to cut off the connection between mobile terminal and communication base stations or Wi-Fi, it is necessary improve electromagnetic shielding efficiency of phone cabinet. This paper analyzes resonant characteristics cabinets. The test method has been introduced. Through Maxwell wave equation boundary conditions, cavity frequency every small drawer on cabinet derived, rectangul...

The most attractive feature of WiMAX is arguable the mobility capability that IEEE 802.16e (IEEE, 2004) standard adds to the previous standard. With mobility support, handover has become one of the most important factors that impact the performance of IEEE 802.16e system. Handover is the process of maintaining active sessions of a mobile station when it migrates from current base station to tar...
