An Indian student at the University of Leicester is making waves with his research on mobile signals that has implications for countries with long coastlines such as India.
Salil Gunashekar, who graduated in Physics from St Stephen's College, New Delhi, has completed his doctoral study on mobile signals and will present key findings of his research at a public lecture on June 5.
His study discovered a particular window of time when mobile signals and radio waves become stronger, allowing them to be clearer and travel greater distances.
The research, examining the signal strength of radio waves travelling over the sea, identified late afternoons and early evenings in spring and summer as a time when enhanced signals occur.
The research has implications for the design of cellular telephone networks operating in marine and coastal regions.
"In today's world, radio waves are an indispensable means of communicating information without wires from one place to another, be it for radio broadcasts or cell phones, television transmissions or airport radars," Gunashekar, who is now a post-doctoral research associate in the Radio Systems Research Group of the university, said.
When radio waves travel for long distances over the sea, their strength can be affected by the weather. The constantly changing weather conditions over the sea mean that marine and coastal environments, in particular, are prone to unusual atmospheric phenomena that enable radio waves to travel longer distances and have higher strengths than expected, he said.
