Sahyadri Innovation Hub designs Li-Phone

The Sahyadri Innovation Hub, has conceptualised and designed a Li-Phone, which uses light source instead of radio waves, and is patented by RDL Technologies, at Sahyadri College of Engineering, Mangaluru.

Addressing reporters here, RDL Technologies Founder Director and CEO Raghavendra G Shetty said that Li-Phone is simply a phone with a difference, but with highly advanced technology. It uses a light source to communicate instead of the radio frequency used by normal cell phones.

"Exposure to cell phone radiation have aroused considerable public attention and scientific debate on health issues. The World Health Organization classified cell phone radiation as "possibly carcinogenic to humans," he added.

In view of the health issues involved in the usage of cell phones, RDL Technologies, sponsored by Sahyadri Innovation Hub, took up the exhaustive research work to find an alternative for RF waves. With a highly talented team of engineers, headed by Raghav Shetty, RDL made a breakthrough after a decade of painstaking research in cell phone technology using a light source, effectively nullifying the health hazard of normal cell phones.

"Cell phones use radio waves to communicate. Radio waves transport digitised voice or data in the form of oscillating electric and magnetic fields called the electromagnetic field (EMF). Radio waves carry the information and travel in the air at the speed of light. Cell phones and other mobile devices emit radiofrequency (RF) waves, a type of non-ionising electromagnetic radiation (commonly called "cell phone radiation"). When you hold or carry a mobile device close to your head and body, you can absorb over half of the transmitted RF energy," he said.

Li-Phone is a mobile device operatively coupled with a base station, which includes a first port for transmitting first data through a communication medium which uses visible light (LED) or Infrared based communication medium. This medium will be a light source. This light source converts the signals from cell phone to the Li-Phone effectively blocking the RF frequency waves. The Li-Phone provides a secure, radiation-free environment, safeguarding humans particularly children from hazardous RF radiation effects.

Li-Phone is a result of high-tech research work, yet it is simple and user-friendly. One just has to keep their mobiles at a secured place or at a corner of their house or office. Switch on the LED light, couple their Li-Phone with their cell phone and start working. It also saves mobile battery while delivering speedy and secure communication. It's sleek and comfortable to handle, he added.
