Sahyadri Innovative Hub invents Li-phone which works from LED light
Mangaluru, July 16: A team of young scientists led by Raghava Shetty of RDL Company, sponsored by Sahyadri Innovative Hub, invented a ‘Li-phone’ which works from LED light being used in house.
Speaking to reporters here on Monday, RDL Technologies Private Limited Founder Director and CEO Raghavendra G Shetty said that the Li-phone would function using the light waves of the LED bulbs. Li-phone is a simple, but invented from highly modern technology. This is different from other phones available in the market. Normally, the cell phones work through radio frequency waves. But in Li-phone would work from LED light. The phone would convert the voice or other sounds into electric signals which then transmitted through radio frequencies in the wind. The cell phone would receive such radio frequencies and reach them to the listeners. This was called radio frequency medium. The ultraviolet rays emitting from such radio frequencies would be more dangerous as they might cause dreaded diseases like cancer. The World Health Organisation (WHO) has also warned against this development. So, he has got the patent for this invention. Now, this phone was invented under the sponsorship of Sahyadri Innovation Hub and it could be used in houses and offices, he said.
The SIM card being used in mobile phones should be connected to the cellular gateway under the LED light. All calls and messages of your cell phones will appear on the screen of the Li-phone. The users could use all their cell phone works. The processing of special frequencies of LED light would convert radio frequencies into data and pass on to Li-phone. The manufacturers could use this technology in all cell phones like WiFi technology, he said.
Pradeep Kumar, Ramachandra Shetty, Kanval Karkera and others were present at the press conference.

According to the Mumbai Metropolitan Region Development Authority (MMRDA), Line 9 is expected to cut travel time between Mira-Bhayandar in Thane district and Mumbai to around 30 minutes from the current one to two hours. Built at Rs 6,607 crore, it will eventually provide seamless connectivity to south Mumbai through interlinking with other lines.
With the addition of the two new lines, Mumbai’s operational Metro network has expanded to six corridors, including Line 1 (Ghatkopar-Andheri-Versova), Line 2A (Andheri West-Dahisar East), Line 7 (Dahisar East-Andheri East) and the underground Line 3 (Colaba-Bandra Kurla Complex-SEEPZ).
As per MMRDA, the revised timetable for Line 2A and Line 7 came into effect on Wednesday, aimed at improving frequency, predictability and overall commuter experience.
It said that with the inauguration of Line 9, Metro Line 2A will now operate as a standalone corridor between Andheri West and Dahisar East, with services from 5.50 am till around 11 pm and a peak frequency of about six minutes.
The integrated Line 7-9 corridor (Gundavali to Kashigaon), spanning 19.79 km, will operate from 5.50 am to 11 pm, with a peak frequency of under six minutes and 276 services on weekdays.
Metro Line 2B (Phase 1) services commenced at 6 am and will run till around 10.30 pm at intervals of approximately nine-and-a-half minutes, operating 209 services daily, according to officials.
MMRDA said the integration of Line 7 with Line 9 enables direct connectivity from Andheri East to Mira-Bhayandar, while Lines 2A and 7 will function as separate corridors.
A seamless interchange facility at Dahisar station will allow passengers to switch between Lines 2A and 7 without exiting the “paid” (ticketed) area.
