NTIA Report TR-98-349A Technological Rationale to Use Higher Wireless FrequenciesFebruary 1998John M. Vanderau, Robert J. Matheson, and Eldon J. Haakinson |
|
|
Abstract: Trends within the wireless and mobile communications industry are examined and extrapolated into the near future. The paper examines the relationships between propagation loss and antenna gain at higher frequencies, shows how dense intelligent infrastructure affects cell size and system capacity, and describes the improving high frequency capabilities of RF electronics technology. The authors conclude that frequencies above 3 GHz may be uniquely suited to many wireless applications, but that non-traditional system architectures and technologies will need to be used. |
Keywords: mobile communications, wireless communications, radio spectrum, microwave radio, MMIC, propagation, antennas, system capacity, technology trends |
