description: Orthogonal Frequency Division Multiplexing (OFDM) is a technology used in the physical layer of wireless communication systems. It encodes digital data on multiple carrier frequencies, allowing for efficient bandwidth use and resistance to interference. In this context, OFDM is used for physical channel mapping, dividing the frequency band into sub-bands with multiple OFDM subcarriers. This enables transmission of multiple parallel OFDM units within an OFDM symbol interval.
explanation: OFDM is classified as a Technology because it's a method used in wireless communication systems to efficiently transmit data. Its application in physical channel mapping, dividing the frequency band for efficient data transmission, further solidifies its classification.
