Ultra wideband communication system and method

摘要

A method of transmitting a data file between a communication device and a portable device in a wireless ultra-wideband communication system using multi-band orthogonal frequency division multiplexing is disclosed. The method comprises: concatenating two or more frequency bands; transmitting data via the two or more concatenated frequency bands to the portable device; and providing means for positioning the portable device in a predetermined positional relationship to the communication device during the data transfer operation.
