Background: Induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. An incoherent noise field is supposed to suppress the bioeffects of regular RF electromagnetic fields. The purpose of this study was to investigate the effect of GSM mobile phone-induced radiofrequency (RF) on the induction of oxidative stress in SP2/0 cell line. Materials and Meth...

Standardized in 3GPP as part of the GSM/WCDMA family, EDGE is a simple and cost-efficient upgrade that provides a more than threefold increase in both the capacity and performance of GSM/GPRS networks. EDGE is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM. The structure of EDGE resembles to that of GSM network that enabl...

An important characteristic of a mobile handset is its ability to receive and transmit power. One way to characterize the performance of a handset in this respect is to use measurements of the spherical radiation pattern from which the total radiated power (TRP), total isotropic sensitivity (TIS), and mean effective gain (MEG) can be computed. Often this kind of measurements are made with a pha...

speech coding in gsm pdf 260 bits.found that the use of GSM coding degrades significantly the identification and. Proposes an in-depth look at the influence of GSM speech coding on text. The full-rate GSM speech codec 2 is a lossy speech coding-decoding.In cellular communication technology, quality of voice output at destination depends on the channel condition. Bad channel condition will produ...

In this paper, we give a review of the tensor method for treating the propagation of scalar and electromagnetic Gaussian Schell-model (GSM) beams. Partially coherent complex curvature tensor is introduced to describe a scalar astigmatic partially coherent GSM beam with twisted phase (i.e., twisted anisotropic GSM beam). A tensor ABCD law for treating the propagation of scalar twisted anisotropi...

Objective(s) The possible risks of radio-frequency electromagnetic fields (EMF) for the living organisms and human body are a growing concern for our society. In this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. Materials and Methods During gestation per...
