Smartphone FM RDS Based Disaster Warning System

By HW Design Labs OPC Private Limited

The solution uses the in-built FM Receiver in Smartphones. FM is free, real-time, doesn’t need any
network and also uses very low battery power. The FM Radio also has another feature to send text messages by
using the RDS feature, a not so popular feature used in India. By encoding the messages to be broadcasted over
RDS, mass public (practically unlimited) can instantly view the messages on screen along with the location details
without internet or any type of data network.
The proposed solution comprises of a Hardware Device and a Mobile Application (Works offline)
1) The Hardware Device is capable encoding messages in RDS format, include the GPS location and broadcast to
long distances (e.g. 10-15km). The device can also be installed on a vehicle, boat or emergency rescue vehicle and
send the live messages while on move. It uses the vehicle battery for its function.
2) The Offline Mobile Application functions similar to the FM Radio app, and in addition it can receive the messages
broadcasted by the disaster management team, provide audio alerts, show the location in the map and live GPS
tracking of the rescue vehicle or boat. The user need only to plug the earphones. By switching the phone in Flight
Mode, the battery drain is low and the phone can provide updates for extended days. (Usually all smartphones die
within 12-24 hours)
3) The proposed solution also provides industry standard encrypted (AES256) messaging for govt officials, rescue
operation teams and selected groups, so as to effectively manage within the team or department in a given
