New NIST Tools to Help Boost Wireless Channel Frequencies and Capacity

Smartphones and tablets are everywhere, which is great for communications but a growing burden on wireless channels. Forecasted huge increases in mobile data traffic call for exponentially more channel capacity. Boosting bandwidth and capacity could speed downloads, improve service quality, and enable new applications like the Internet of Things connecting a multitude of devices. Kate Remley To support wireless communications at higher frequencies offering more channel capacity, NIST engineer Kate Remley led development of this new 94 gigahertz calibrated signal source for testing receivers and other devices.
