Evaluation and modelization of TVWS radio propagation channels for IoT applications in the context of NDT devices in remote areas

物联网（IoT）是全球通信网络的下一步， 连接到互联网并且可以彼此通信或者与电子设备的远程计算机通信。 据估计，全球正在出货超过1000亿台支持机器对机器（M2M）的设备 每年.除了远程监控方面，物联网系统通常还支持远程控制。的 智能设备和用户界面之间的连接通常通过有线或无线通信网络来完成。 基础设施演进作为示例，许多智能设备（例如，智能汽车）具有嵌入式3G或4G调制解调器，以 启用远程访问。然而，在一些应用中，设备被部署在没有无线网络的偏远地区。 基础设施是可用的（例如，农业农场、风力农场）。Nutaq提供远程连接解决方案 基于TV白色空间（TVWS）的区域。TVWS指的是电视频道频率是空置在一定的时间， 地理位置，即不被任何地面电视广播服务使用。特定应用 现场放置的无损检测（NDT）设备的连接。目前没有解决方案 了该项目将包括使用Nutaq的设备进行现场建模，评估和 技术的演示。该项目还将包括使用一个复杂的信道模拟 拉瓦尔大学开发的工具。这些测试将使Nutaq及其合作伙伴能够确定 在已经/将要部署NDT设备的真实的现场位置覆盖其解决方案;代表性 地点将由Nutaq及其合作伙伴提供。不同的信道模型、频率、功率电平和 天线将被考虑。通过这个研究项目，Nutaq将能够为加拿大工业提供 通过一个完整的解决方案，将远程设备连接到互联网，即使在没有基础设施的情况下， 地方虽然拟议项目的重点是无损检测，但这项研究的结果很容易被 外推到其他应用领域（农业，采矿，能源），将受益于低成本和低成本 为远距离无线电接入提供动力。

The Internet of Things (IoT) is the next step in the global communications network in which objects are connected to the Internet and can communicate with each other or with a remote computer of electronic device. It is estimated that over 100 billion machine-to-machine (M2M) enabled devices are being shipped globally each year. Beyond the remote monitoring aspects, IoT systems often support remote control as well. The connectivity between smart devices and the user interface is typically done through a wired or wireless infrastructure. As an example, lots of smart devices (e.g. smart cars) have embedded 3G or 4G modems to enable remote access. However, in some applications the devices are deployed in remote areas where no infrastructure is available (e.g., agriculture farms, wind farms). Nutaq offers a connectivity solution for remote areas based on TV white space (TVWS). TVWS refers to TV channel frequencies that are vacant at a certain geographical location, i.e., not used by any terrestrial television broadcast services. A particular application is the connection of Non Destructive Test (NDT) devices placed in the field. There is currently no solution for that. The project will include the use Nutaq's equipment to perform field modelization, evaluation and demonstrations of the technology. The project would also include the use of a sophisticated channel simulation tools developed by Laval University. These tests will enable Nutaq and its partner to determine the potential coverage of their solution in real field locations where NDT devices have been/will be deployed; representative locations will be provided by Nutaq and its partner. Different channel models, frequencies, power levels and antennas will be considered. With this research project, Nutaq will be able to provide the Canadian industry with a complete solution to connect remote devices to the Internet, even where there is no infrastructure in place. Although the focus of the proposed project is NDT, the results of this research could easily be extrapolated to other field of application (agriculture, mining, energy) that would benefit from low cost and low power radio access over extended distances.
