Dial-a-frog – researchers develop the ‘FrogPhone’ to remotely call frogs in the wild

Researchers have developed the ‘FrogPhone’, a novel device which allows scientists to call up a frog survey site and monitor them in the wild. The FrogPhone is the world’s first solar-powered remote survey device that relays environmental data to the observer via text messages, whilst conducting real-time remote acoustic surveys over the phone. These findings are presented in the British Ecological Society Journal Methods in Ecology and Evolution today.

The FrogPhone introduces a new concept that allows researchers to “call” a frog habitat, any time, from anywhere, once the device has been installed. The device has been developed at the University of New South Wales (UNSW) Canberra and the University of Canberra in collaboration with the Australian Capital Territory and Region Frogwatch Program and the Australian National University. 

The FrogPhone utilises 3G/4G cellular mobile data coverage and capitalises on the characteristic wideband audio of mobile phones, which acts as a carrier for frog calls. Real time frog calls can be transmitted across the 3G/4G network infrastructure, directly to the user’s phone. This supports clear sound quality and minimal background noise, allowing users to identify the calls of different frog species. MORE
