Abstract

An ultra-wideband communications network and methods for communication are provided. In one embodiment, an ultra-wideband transceiver transmits video data that is in a lossy or lossless compression format. The lossy or lossless format may be a wavelet-based format. The transmitted ultra-wideband signal may be transmitted in a single or in multiple radio frequency bands. The network may further include a second ultra-wideband transceiver and a video display device. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
