We are experiencing today an explosion in wireless network traffic driven by the rapidly growing number of mobile devices and bandwidth hungry applications. Industry research predicts a 1000-fold increase in aggregate bandwidth demands by 2020. In spite of decades of research on improving spectrum efficiency in WiFi and cellular networks, existing techniques can only offer short-term solutions. The millimeter-wave (mmWave) technology, e.g., in the unlicensed 60 GHz band supported by the IEEE 802.11ad standard, has recently emerged as an alternative to legacy WiFi, promising multi-Gigabits per second throughput. Although the commercial use of 60 GHz hardware has been limited until recently to short-range line-of-sight scenarios, e.g., wireless docking, due to the high attenuation and vulnerability to blockage of mmWave signals, this project envisions the use of mmWave technology for building general purpose, multi-Gigabit wireless Local Area Networks for home and enterprise environments that will offer always-on connectivity but an order of magnitude higher throughput than today's 2.4/5 GHz WiFi networks. One major factor that has hindered research efforts towards this vision is the lack of testbeds due to the unavailability of 60 GHz hardware that can simultaneously offer both high performance and high levels of reconfigurability and control. This project will build X60, a software defined based 60 GHz testbed that will offer high level of reconfigurability at the PHY, MAC, and network layer, and, at the same time, support channel widths and speeds commensurate to those of the IEEE 802.11ad standard. Each testbed node consists of an FPGA-based mmWave Transceiver from National Instruments integrated with a 12-element phased antenna array from SiBeam Inc. With no other testbeds of similar capabilities available in the wireless networking community, the use of FPGAs lends full flexibility and enables one to implement a broader range of communication and networking solutions, ranging from the current standard itself to radically new communication and networking solutions. Starting from the broadband characterization of the channel, innovative modulations that maximize the spectral efficiency and new physical layer (PHY) synchronization mechanisms will be developed as part of this project. At the Medium Access Control (MAC) layer, novel beam forming/beam steering and rate adaptation algorithms as well as loss differentiation algorithms will be studied. At the network layer, the project will investigate the use of wireless relays and smart reflector arrays to improve connectivity, coverage, and network capacity, as well as explore a radically new integrated PHY/MAC cross-layer architecture founded on soft code-division multiplexing/multiple access principles - an approach fundamentally different from that of the IEEE 802.11 standards. The project will make the the developed software for the X60 testbed and the measurement data generated from research projects enabled by this infrastructure available to the wireless networking community.

今天，我们正在经历无线网络流量的爆炸，这是由迅速增长的移动设备和带宽饥饿的应用程序驱动的。行业研究预测，到2020年，总的带宽需求增加了1000倍。尽管有数十年的研究提高了WiFi和蜂窝网络的光谱效率，但现有技术只能提供短期解决方案。毫米波（MMWAVE）技术，例如，在由IEEE 802.11AD标准支持的无牌60 GHz频段中，最近已成为传统wifi的替代方案，有望每秒吞吐量。尽管直到最近才将60 GHz硬件的商业用途限制在短期视线线程中，例如，由于衰减且易受阻止MMWave信号的较高的衰减和脆弱性，该项目设想使用MMWave技术在构建多数无线网络的范围内，以构建MMWave技术，以便在较高的范围内构建范围，这些秩序始终提供范围的范围，但会提供巨大的范围，但要提供范围的范围，但要提供范围内的范围，但要提供范围内的网络连接2.4/5 GHz WiFi网络。阻碍了对该愿景的研究工作的一个主要因素是由于60 GHz硬件无法同时提供高性能和高水平的可重构性和控制力，因此缺乏测试台。该项目将构建X60，这是一个基于60 GHz测试的软件，它将在PHY，MAC和网络层提供高度的可重构性，同时支持与IEEE 802.11AD标准的频道宽度和速度。每个测试床点由基于FPGA的MMWave收发器与来自Sibeam Inc.的12个元素分阶段天线阵列集成的国家仪器的收发器组成。没有其他类似功能的测试台可在无线网络社区中可用，FPGAS的使用完全灵活性，并可以实现跨越跨越的沟通范围，以新的沟通和网络范围进行了跨越范围的跨性别范围。从通道的宽带表征开始，将作为该项目的一部分开发出最大化光谱效率和新物理层（PHY）同步机制的创新调制。在中型访问控制（MAC）层，将研究新颖的束形成/梁转向和速率适应算法以及损耗分化算法。在网络层，该项目将调查无线继电器和智能反射器阵列的使用，以提高连接性，覆盖范围和网络容量，并探索建立在软代码多路复用/多个访问原理上的根本新的集成PHY/MAC跨层架构 - 与IEEE 802.11标准标准的方法根本不同。该项目将使已开发的X60测试床的软件以及由无线网络社区提供的基础架构启用的研究项目产生的测量数据。
