NYU Polytechnic's Wireless Research Center (NYU Wireless) is actively pushing millimeters in response to the industry's Brooklyn 5G Summit, which was held in New York earlier this year, to launch a wave of 5G cellular plans. The wave (mmWave) band serves as a new field of wireless communication. The center believes that millimeter-wave frequencies between 10 and 300 GHz provide critical connectivity for densely populated urban areas and meet the fifth-generation services expected to begin in 2020.
“Many companies have released very important 5G development plans. They are really committed to trying to develop this technology,†said Sundeep Rangan, deputy director of NYU Wireless, which confirms that the field represents significant business impact. Researchers at the Brooklyn Summit show end-to-end transmission of high-resolution video streams over the 60 GHz frequency range. The system includes various modules for synchronization, equalization, and enhancement coding.
"The technology will be fully developed by 2020. We are not too far away from that time. Many activities have been carried out for early prototypes," said Theodore Rappaport, Director of NYU Wireless, "Expecting 5G and Millimeter Wave Systems Standardization will begin in the coming year, and you will see 5G becoming a convergence technology that extends the current 4G LTE standard in a gradual way."
Test new antennas and receivers
NYU Wireless has been testing next-generation communications for many years, measuring and modeling millimeter waves, especially at 28 GHz and 38 GHz. The researchers found 75 and 8 locations in Manhattan and Brooklyn, and placed base stations with less than 100 miliWatt directional antennas on the roof, looking far below the power level of today's base stations.

“You don't have to be completely in line of sight. You can also install it on a few streets or even near the corner, but the energy still works. It actually provides a lot of multipath, powerful reflections and surprisingly large amounts of scattering. Rappaport added that his team used a combination of beams to extend the antenna range to more than 1,000 feet. "If you replace the receiver's omnidirectional antenna with a directional antenna, you can actually overcome the challenges of space loss, conduction, and cellular systems."

Directional antennas can penetrate leaves and reflect buildings, but it can be more difficult to penetrate buildings and floors with metre waves. In addition to the access points required for the building, Rappaport believes that 64 units can be installed at a base station 200 meters away per square foot in a densely populated area such as New York City. By then, such a architecture will achieve a data rate of 2-6 Gbit/s, but users may experience tens of Gbit/s of progress.
"We are also studying LTE and how to improve existing LTE systems, beamforming technology, signal processing technology to achieve a new millimeter wave future - wireless devices have dozens of antenna units, and the base station has thousands of Antenna units." The Wireless Research Center has partnered with other NYU agencies and radiologists to study the biological effects of millimeter waves and to improve signal processing techniques such as accelerated nuclear magnetic resonance and real-time imaging. In addition, NYU professor JusTIn Cappos designed a solution to protect personal passwords from hackers; CapposYanyan Zhuang is also working to reduce the risk of hacker attacks on smartphone sensors. “Early measurements really made our eyes shine, and we are making these measurement achievements push our research program to even greater possibilities,†Rappaport said.
