The broader impact/commercial potential of this I-Corps project covers nearly all applications related to next generation mobile communications technologies, such as connected cars, drones, robots, and smartphones. This wireless technology can unlock the true potential of higher frequency bands by establishing more efficient and robust connections that operate in the millimeter Wave (mmWave) spectrum above 28 GHz. The resulting increased wireless capacity and reduced latency will enable the key use cases that have been defined in the context of 5G, such as interactive Augmented Reality/Virtual Reality (AR/VR), autonomous driving, and unmanned robotics. Rapidly exchanging large amount of information wirelessly will be of paramount importance for AR/VR, as it will permit getting rid of the cables connected to the headsets, and for autonomous automotive and robotic systems, as it will enable beyond line-of-sight vision by broadcasting with minimal latency massive amount of data generated by sensors such as lidars, radars, and cameras.This I-Corps project focuses on the design of an all-digital transceiver radio for mmWave communications. The mmWave frequencies of above 28 GHz are necessary to alleviate the spectrum crunch in the traditional cellular bands, and to make ultra-fast 5G use cases a reality. However, challenging propagation characteristics at these frequencies necessitates the use of transceivers that not only operate over low power budgets, but also deliver the robustness that the wireless ecosystem demands. Existing state-of-the-art mmWave analog transceiver radios trade-off robustness against power: they allow the radio to transmit or receive in only one direction or a small number of directions at a time. Conversely, this all-digital beamforming technology allows to look in all directions simultaneously, resulting in more spectral-efficient and robust communications. The defining technical feature in this design is that the signals from each antenna chain are digitized independently, as opposed to existing techniques where the signals from each antenna are first combined in analog and then digitized.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力涵盖了几乎所有与下一代移动通信技术有关的应用程序，例如连接的汽车，无人机，机器人和智能手机。这种无线技术可以通过在28 GHz以上的毫米波（MMWave）频谱中建立更高效，更强大的连接来释放高频带的真正潜力。由此产生的无线容量和延迟减少将使在5G背景下定义的关键用例，例如交互式增强现实/虚拟现实（AR/VR），自主驾驶和无人驾驶机器人技术。 Rapidly exchanging large amount of information wirelessly will be of paramount importance for AR/VR, as it will permit getting rid of the cables connected to the headsets, and for autonomous automotive and robotic systems, as it will enable beyond line-of-sight vision by broadcasting with minimal latency massive amount of data generated by sensors such as lidars, radars, and cameras.This I-Corps project focuses on the design of an MMWave通信的全数字收发器无线电。以上28 GHz的MMWAVE频率是减轻传统细胞带中的频谱紧缩的必要条件，并使超快速的5G用例成为现实。但是，在这些频率上具有挑战性的繁殖特征需要使用不仅在低功率预算上运行的收发器，而且还提供了无线生态系统所需的鲁棒性。现有的最先进的MMWave模拟收发器无线电反对权力的稳健性：它们允许无线电一次仅在一个方向或少数方向上传输或接收。相反，这项全数字波束形成的技术允许同时朝各个方向展示，从而导致更加频谱和健壮的通信。 该设计中的定义技术特征是，来自每个天线链的信号是独立数字化的，而不是现有技术，该技术首先将每个天线的信号首先合并为模拟，然后数字化。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和广泛的影响来评估NSF的法定任务。
