Abstract

A transmitter system is provided. In one embodiment, the transmitter system includes a data modulation unit, which generates a stream of data that is synchronized with a master clock. The transmitter system additionally includes a transmitter that transmits the stream of synchronized data by way of an attached antenna. In another embodiment the transmitter system includes a Medium Access Control (MAC) layer. 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.
