Calcutta tops the chart in generating e-waste after Mumbai, Delhi-NCR, Bangalore and Chennai.

Concerned over possible health risk posed by cell phone towers, the National Green Tribunal today directed the Centre to inform it whether the construction of these towers in residential areas woul

Inmarsat, which provides mobile telecommunications, is attempting to put up the third spacecraft in its next-generation global network.

Non-thermal microwave/lower frequency electromagnetic fields (EMFs) act via voltage-gated calcium channel (VGCC) activation. Calcium channel blockers block EMF effects and several types of additional evidence confirm this mechanism. Low intensity microwave EMFs have been proposed to produce neuropsychiatric effects, sometimes called microwave syndrome, and the focus of this review is whether these are indeed well documented and consistent with the known mechanism(s) of action of such EMFs.

London-based Inmarsat hopes to get its latest next-generation spacecraft into orbit at the end of the month.

Reforming fossil fuel subsidies could free up enough funds to finance universal access to water, sanitation, and electricity in many countries, as well as helping to cut global greenhouse-gas emissions.

There is no decisive data or evidence so far to show that radiations from mobile phones or towers have adverse health or environmental effects in India, a top BSNL official here said.

In August, millions of Sprint customers will receive letters from the telecom giant that will look like ordinary pieces of white paper, but will be made from fibers from wheat fields instead of for

This paper presents viability study of integrated renewable power system for telecommunication applications. Rapid depletion of fossil fuel resources necessitated research on alternative energy sources. A wind solar integrated system is a reliable alternative energy source because it uses solar energy combined with wind energy to create a stand-alone power system. Incremental Conductance and Fuzzy Logic Maximum Power Point Tracking is proposed in this paper for solar and wind power system to provide a constant voltage with the help of DC-DC Single-Ended Primary-Inductance Converter.

BHOPAL: National Green Tribunal (NGT) has ordered Bhopal municipal corporation (BMC) to carry out fresh survey of mobile towers in its jurisdiction to find out whether they are in 100 metres of vul
