Objective(s): The increasing rate of over using cell phones has been considerable in youths and pregnant women. We examined the effect of mobile phones radiation on genes expression variation on cerebellum of BALB/c mice before and after of the birth. Materials and Methods: In this study, amobile phone jammer, which is an instrument to prevent receiving signals between cellular phonesand base t...

In multiple-access communication systems co-channel interference can be mitigated by applying multiuser detection instead of treating the interference as additive noise [1]. In this paper we focus on downlink operation in a GSM-like TDMA network and investigate multiuser channel estimation and data symbol detection of two users that share the same physical channel in two adjacent cells. Such a ...

Passive Coherent Location (PCL) requires detailed knowledge about the geometric transceiver-receiver-constellations and the technical parameters for simulating the effective field of view. Geographic Information Systems (GIS) provide tools to fuse spatial information with technical metadata to evaluate individual geometric constellations and obtain optimal radar coverage. This paper presents a ...

As has been widely discussed, the GSM mobile telephony system only offers unilateral authentication of the mobile phone to the network; this limitation permits a range of attacks. While adding support for mutual authentication would be highly beneficial, changing the way GSM serving networks operate is not practical. This paper proposes a novel modification to the relationship between a Subscri...

Mobile cellular CDMA networks for tactical applications require mobile base stations in order to provide communications on the moue. Because of the mobility of the base stations, power balancing among the transmitters at different base stations is more dificult than in commercial cellular CDMA systems. Handoff of mobiles among base stations is also more difficult, primarily due to the mobility ...

BACKGROUND The purpose was to investigate mobile phone interference with implantable deep brain stimulators by means of 10 different 900 Mega Hertz (MHz) and 10 different 1800 MHz GSM (Global System for Mobile Communications) mobile phones. METHODS All tests were performed in vitro using a phantom especially developed for testing with deep brain stimulators. The phantom was filled with liquid...

OBJECTIVE To test whether people who report being sensitive to mobile phone signals have more symptoms when exposed to a pulsing mobile signal than when exposed to a sham signal or a non-pulsing signal. DESIGN Double blind, randomised, within participants provocation study. SETTING Dedicated suite of offices at King's College London, between September 2003 and June 2005. PARTICIPANTS 60 "...

 Poor accuracy of frequency references used in GSM Base Transceiver Stations (BTS) can lead to dropped calls, slow handover between cells and even co-channel interference. In this paper, we report some results of an experimental trial carried out in the Omnitel-Vodafone test plant in Milano (Italy). In authors' knowledge, this is the first paper confirming with experimental data that lack of B...

OBJECTIVES The objective of this study was to examine whether acute exposure to radio frequency electromagnetic fields (REFs) emitted by mobile phone may affect subjective symptoms. METHODS Three large groups of volunteers (total 496) were exposed to REFs emitted by mobile phones in one session and sham signals in a different session. REF and sham exposure sessions were counterbalanced and do...

Wireless Mesh Network (WMN) is an ad-hoc network with a fixed network infrastructure (see an example in figure 1). The physical structure of a WMN includes base stations, a backbone and mobile stations. The base stations (also known as mesh routers or mesh points) are static wireless nodes, forming the network infrastructure and providing wireless network access to the mobile stations. The back...
