OFDMA as the Technology for the Next Generation Mobile Wireless Internet

The development of wireless systems, with the profound focus on the Internet, and mobile computing platforms has generated much interest in mobile data network access, particularly the Broadband wireless communication system. The choice for the appropriate technologies that will specifically suit the applicability for the Next Generation mobile wireless internet system will be based on various factor from high speed connectivity to mobility. Since OFDMA (orthogonal frequency division multiple access), based on OFDM, can overcome signaling transmission barriers and increase transmission speed, while coping with unpredictable changes of the radio frequency environment, it is well suited for mobility applications in the wireless broadband network.
