NeTS: Medium: Massive Mobile Broadband Communications with Millimeter Wave Picocellular Networks

该项目考虑基于毫米波（mmWave）频段的蜂窝系统，在30到300 GHz之间，可用带宽比现在宽得多。S蜂窝网络[4-6]。事实上，这些频率的可用频谱可以轻松地比目前3ghz以下所有蜂窝分配的频谱多200倍。此外，毫米波信号的非常小的波长与低功率CMOS射频电路的进步相结合，使大量的小型化天线能够被放置在小尺寸上。这些多天线系统可用于形成非常高增益、可电操纵的阵列，可在基站、手机外壳甚至芯片中制造。由于毫米波信号的范围有限，该提案设想基于大量毫米波皮细胞的蜂窝系统。（半径100到200米），每个都使用高定向天线，以提高范围和空间分离。将大幅增加的带宽与高维多天线传输（如毫米波皮蜂窝系统）的空间复用增益相结合，可能提供比当前商业网络多1000倍的容量。该项目将为将毫米波技术引入多用户、多蜂窝环境提供基础，并使毫米波系统能够用于具有移动性的广域网。与该领域领先的设备供应商合作，pi旨在推动设备和协议开发方面的创新，并在这一新兴的无线通信领域培养新一代研究生和本科生。增强的吞吐量增益可能接近当前无线蜂窝网络吞吐量的1000倍，这将彻底改变无线宽带行业，并改善向用户提供的网络服务。

This project considers cellular systems based in the millimeter wave (mmWave) bands, between 30 and 300 GHz, where the available bandwidths are much wider than today?s cellular networks [4-6]. Indeed, available spectrum at these frequencies can be easily 200 times greater than all cellular allocations today under 3 GHz. Moreover,the very small wavelengths of mmWave signals combined with advances in low-power CMOS RFcircuits enable large numbers of miniaturized antennas to be placed in small dimensions. These multiple antenna systems can be used to form very high gain, electrically steerable arrays, fabricated at the base station, in the skin of a cellphone, or even within a chip. Due to the limited range of mmWave signals, the proposal envisions cellular systems based on large numbers of mmWave ?picocells? (100 to 200m radius), each using highly directional antennas for improved range and spatial separation. Combining dramatically increased bandwidths with spatial multiplexing gains from the high-dimensional multiple antenna transmissions such mmWave picocellular systems offer the possibility of of 1000 times more capacity than current commercial networks.This project will provide a basis for bringing mmWave technologies to a multiuser, multi-cellular setting and enable mmWave systems for wide-area networks with mobility. With partnerships from leading device vendors in this space, the PIs aim to drive the innovation forward in terms of device and protocol development, and train a new generation of students at the graduate and undergraduate level in this emerging area of wireless communications. The enhanced throughput gains that could approach 1000x current wireless cellular network throughputs would revolutionize the wireless broadband industry and lead to improved delivery of network services to users.
