Collision rectification in wireless communication devices
First Claim
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.

Abstract
Wireless communication networks utilize various communication protocols to exchange data between wireless network devices. Overlapping communication frequencies between data exchange protocols present a collision problem when data transmissions interfere with one another during wireless transit. A device for moderating transmission traffic in a wireless network where overlapping communication frequencies coexist is described to reduce or avoid interference caused by signal collisions.

10. A data collision rectification device for use in a wireless communication network wherein frequency-overlapping protocols comprising a first protocol and a second protocol are used to exchange information between a plurality of data transfer nodes and result in periodic collisions when information is transmitted by the first and the second protocol in frequency-overlapping manner, the device comprising;
-
