Puri: In a bid to curtail the communication hurdle during times of distress, a unique tool of communication 'Ham radio' has become handy in disseminating information. Also termed as amateur radio, the tool uses ionospheric propagation and direct web propagation to establish communication.
The non-dependence on any relay system makes the radio operate under any circumstance. With no interference or servers, the signals reportedly go straight from the sender to the ionosphere, from where it directly reaches the receiver.
