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.
To help solve the wireless crowding conundrum and support the next generation of mobile technology—5G cellular—researchers at the National Institute of Standards and Technology (NIST) are developing measurement tools for channels that are new for mobile communications and that could offer more than 1,000 times the bandwidth of today’s cell phone systems.
Like pioneers who found land by going west, telecom researchers can find open spectrum by going up—to higher frequencies. Mobile devices such as cell phones, consumer WiFi devices and public safety radios mostly operate below 3 gigahertz (GHz) (see infographic). But some devices are starting to use fast silicon-germanium radio chips operating at millimeter (mm) wavelengths above 10 GHz. Researchers at NIST and elsewhere are eyeing channels up to 100 GHz and even beyond.
