Quantum Communication

Quantum communication refers to an almost hackproof communication with use of quantum cryptography. The most common application of quantum cryptography is Quantum Key Distribution (QKD in which the quantum mechanical effects are used to perform cryptographic tasks. Quantum communication boasts ultra-high security communication and uses subatomic particles to securely communicate between two points. In case intruder (hacker) ..


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 ..

Recently, the Cold Atom Laboratory team announced that they have succeeded in producing a Bose-Einstein condensate at NASA’s Jet Propulsion Laboratory. This is being touted as a key breakthrough for the CAL which shall debut on space station in late 2016. This backgrounder discusses the basics of CAL. What is Cold Atom Laboratory? The Cold ..

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 ..
