1. A method for collision avoidance in a wireless network wherein a first protocol and a second protocol are utilized by a plurality of data transfer terminals to transmit data over at least partially overlapping frequencies, the method comprising:

  • acquiring timing statistics reflective of a first data schedule for the first protocol and the second protocol during the data transmission between the plurality of data transfer terminals;

    analyzing the timing statistics of the first data schedule to identify impending collisions resulting from frequency-overlap in data transmission in the first and the second protocols;

    constructing a second data schedule in which the data transmission in the first and the second protocol are arranged in a non-colliding order; and

    transmitting a jamming signal to manipulate the data transmission in at least one of the protocols thereby conforming the data transmission to the second data schedule such that subsequent data transmission occurs without collision.
