ABSTRACT
The rapid growth of Internet content and media streaming options, coupled with increasing bandwidth of broadband access (AC) technologies, has created an ecosystem of products and services that creates a demand for media in the home. The Institute of Electrical and Electronics Engineers (IEEE) 1901 standard specifies the physical layer (PHY) layer and medium access control (MAC) layer functionalities for high-speed communication over electrical power lines. The IEEE 1901 PHY and MAC layers correspond to the lowest two layers of the basic reference model for open systems interconnection specified by the International Organization for Standardization (ISO). The higher layer entity (HLE) corresponds to all the layers responsible for generating traffic to be transmitted using the IEEE 1901 fast Fourier transform-Orthogonal frequency division multiplexing (FFT-OFDM) device. The HLE communicates the data and the control information using the service access points (SAPs). The OFDM is a modulation technique that easily adapts to frequency-selective channels.
