Report in a Nutshell

This report evaluates the CDMA technology from both the technical and operational viewpoints, including the history of the technology, current trends, and future prospects. It also analyzes the applications compliant with CDMA technology, including under-development applications. In addition, OFDM technology is evaluated, compared and contrasted with CDMA, along with the relationship between OFDM and OFDM-based 4G technologies. Finally, the report includes a comprehensive analysis for CDMA vendors, including recommendations for those vendors to grow their businesses. This report will benefit communications and RF engineers, CDMA design engineers, wireless communications vendors and service providers, any wireless technology company with applications based on CDMA, and those interested in learning more about wireless technologies.
