Regularities seen in the calls of frogs can be used to improve radio communications systems, according to the findings of a Japanese scientific team led by Ikkyu Aihara, an assistant professor at the University of Tsukuba.
The findings were published in the British science journal Royal Society Open Science issued Wednesday. The mechanism of the behaviour is expected to help avoid so-called packet collisions, a data communication failure in smartphones and other devices, and could eventually contribute to energy savings.
Packet collisions occur when multiple devices simultaneously emit radio waves that interfere with each other, preventing the sending and receiving of data. The reduction of such collisions is key to improving telecommunication technology.
According to the team's announcement, the scientists recorded and analysed the sounds of three Japanese tree frogs. They found that a group of frogs delays, or "trolls," the timing of their calls so as not to interfere with each other, and the group overall regularly switches between calling together and resting together.
