The article discusses the challenges in using orthogonal frequency division multiplexing (OFDM) technology for mobile systems. Radio channel environments for mobile communications environments are analyzed to present an outlook for fourth-generation (4G) cellular data networks. The issues of practical transmit power, the need for co-channel interference management and challenges in realizing optimal levels of per-subcarrier power control are areas of network engineering relevant to OFDM-based mobile systems.
