Would it be possible to create some kind of network of wifi receptors all over the city? Or use an existing network (Tikona, for example) to scan for distress signals from phones or other devices? The range of a wifi being relatively small, it shouldn't be too complicated to mark a fairly accurate area to dispatch cops.
This is the hardware.
The software will be on multiple levels.
On the user's end, it can be a simple phone application. Or it can be an alarm installed in a building or it can be sent from a laptop or other computer. When an alarm is triggered, basic information on location if any from the device GPS, phone number and the call for help should be broadcast from wireless, as well as SMS. It should continue to broadcast periodically on wireless as well as send SMS if any information changes (location, phone number, whatever). The phone must automatically start recording audio and switch to silent mode.
The application in all its forms should have the ability to pick a distress signal and communicate information to the police - or, in the absence of both phone and internet connectivity, bounce the signal further and enhance its reach. It should relay any return signal back as well in a similar manner. In this manner, all available wifi enabled phones could be used to support the police network.
On the police end, receiving a signal should result in the police network being informed and dispatched as per their protocols - treating it like a phone call to the police line with address information attached. The operator must attempt to call and confirm the emergency. This call May or may not be picked by the person depending on circumstances.
Police vans must have wifi capabilities of smaller range, to be able to further narrow down the location.
Such a solution should not be too difficult to design. Wifi capabilities exist as well as mesh networking research. This will not need anything major. In fact, the more primitive, the less open to exploitation.
Such a system also has fewer chances of misuse, as it will be designed to transmit all possible personally identifying and locating information. This would be scalable as well as reproducible in other parts of India.
Basic networks once established could aid in all kinds of things.
Will refine the idea as needed, but what do you think? Good idea?
