Abstract
Official abstract text for this publication.
Segmented frames of data may be transmitted from a transmitting device using conflict free slots (CFS) within a carrier sense multiple access with collision avoidance (CSMA/CA) protocol on a noisy media. At a receiver, a segmented frame of data is received. The data is represented by a plurality of tones. If requested by the transmitter, a tone map response command is prepared that specifies a set of optimized tone map parameters by analyzing the received frame of data. Any previously determined tone map response commands to the transmitting device are deleted. A sequence of frame segments may be received in conflict free slots, but only one tone map response is transmitted to the transmitting device after receiving the entire sequence of frame segments.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transferring frames of data using carrier sense multiple access with collision avoidance (CSMA/CA) on a noisy media, the method comprising: receiving a frame of data via the noisy media from a transmitting device, wherein the data is represented by a first plurality of tones; receiving a tone map request with the frame of data; preparing a first tone map response command that specifies a set of optimized tone map parameters by analyzing the…
