Chandy was to inaugurate this event through mobile after he could not reach the venue, hence he connected over phone.
"There were two things that we saw today in CM's address. One he was able to connect to the conference even after bad weather.
"The other thing is his call dropped because signal levels are lower in the country because of low radiation emitted by mobile towers," telecom regulator TRAI member R K Arnold said while speaking at the event.
"Stringent standards have been adopted in India for mobile radiation by India than preferred in US and Europe. There is misinformation among common public which I believe this event will help to resolve," he said.
