ABSTRACT:
A method for communication includes transmitting a first datum using an electromagnetic wave of a first wavelength, and, while transmitting the first datum, detecting an energy level of an electromagnetic wave of a second wavelength. A collision is declared if the energy level of the second wavelength exceeds a threshold value.
