The study aims to identify the technological potential and limitations of various types of Wireless Power Transfer (WPT) applications specific to the electric utility industry. The paper presents an analysis of the technology, the classifications and the key drivers for WPT, based on available technologies. A summarized assessment of risks and obstacles facing the technology is presented.
A study of airport WiFi band usage and wireless device capabilities reveals that the 5 GHz WiFi bands are significantly underused, compared to the 2.4 GHz band. After uncovering this data trend in studies of airport channel usage, a search of newly manufactured wireless devices showed that many new devices do not possess the capability to operate in the 5 GHz bands. Furthermore, the UNII bands allocated...
Recent measurements find that 80% of WiFi devices crowd into the 2.4 GHz band, ignoring the greater bandwidth and reduced congestions available in the 5.8 GHz band. Even worse, within the 2.4 GHz band a few channels carry the majority of the traffic. This spectral crowding makes no technical sense when there are other channels and far less congested bandwidth available to these devices. The trend...
Nuclear power plants (NPPs) in the United States have been upgrading their instrumentation and control (I&C) equipment from analog to digital systems over the past 10 to 15 years. Upgrades have been occurring on the plant floor for I&C systems including generator controls, turbine supervisory controls, and chiller controls as well as for plant control systems in control rooms. Because of the...
