What is Spectrum Cap?

The spectrum cap is the limit of radiowaves a telecom operator can hold for providing wireless services. Spectrum cap rules prevent an operator from buying additional spectrum in a respective band. The idea is to prevent operators from acquiring a disproportional amount of spectrum compared to its peers thereby preventing market dominance. As per existing ..

India’s Mobile Tower Radio Emission Norms

Telcos say that they are not allowed to expand tower network due to emission issues. Emissions from mobile towers are considered safe as it is non-ionising or “low energy” radiation, which cannot alter the human DNA. At most, it can only induce thermal effects by way of mild arming of the body. Only ionising or ..

CERN’s LHC discovers new class of particles called Pentaquarks

Scientists at CERN’s Large Hadron Collider (LHC) have discovered a new class of exotic subatomic particles called the Pentaquarks. The discovery was made by the scientist’s after watching the decaying of a subatomic type particle known as the Lambda B baryon. Facts about Pentaquark Pentaquark was first predicted to exist in the 1960s and its ..
