Powering the various elements of IoT networks is a major constraint on the scale, installation and maintenance cost and sustainability, as IoT devices are typically either battery or mains-powered. Lightricity already addresses these limitations for the end-nodes (e.g. sensors/tracker tags), using its world-leading efficiency indoor photovoltaic technology to harvest energy from indoor and ambient lighting. This avoids the cost and inconvenience of ever having to change a battery, and the environmental impact of massive battery waste. Lightricity broadcast-only BLE-based tags/sensors are generally used in star topology IoT networks, where every tag communicates directly with a fixed (wired) gateway device receiving and passing data it to the backend (Cloud) for analytics. Gateways, however, are too power-hungry for harvested light energy. With typical BLE tags network range is limited by tag broadcast range, necessitating a gateway in every room, implying very large gateway numbers (many 100-1,000's) for big buildings e.g. airports, hospitals, warehouses, exhibition centres.Mesh networking topology addresses the cost, inconvenience and easy scalability of networks by adding battery-powered relays/anchors to massively reduce the need for gateways. These relays receive and send data from end-nodes and route network data optimally to a single or small number of gateways per building. They still require significantly more power than end-nodes. However, with recent improvements in mesh technology and a series of innovations we propose in this project, particularly to improve light capture, powering them with harvested light energy is now within reach. This project will make the vast majority of a mesh IoT network's infrastructure independent of battery or mains power thus achieving low cost, sustainable scalability.This proposed industrial stage R&D project aims to develop prototype light energy harvesting-powered BLE-based Wirepas Mesh relays and bidirectional sensor end-nodes. Crowd Connected will test the resulting devices in real environments that challenge the performance limits.

为物联网网络的各种要素提供动力是对规模，安装和维护成本和可持续性的主要限制，因为物联网设备通常是电池或电源供电的。 Lightricity使用了世界领先的室内光伏技术来从室内和环境照明中收集能量，从而解决了最终节点（例如传感器/跟踪器标签）的这些局限性。这避免了不得不更换电池的成本和不便，以及大量电池浪费的环境影响。 Lightricity仅基于BLE的标签/传感器通常用于星形拓扑IoT网络，每个标签都会与固定的（有线）网关设备直接通信，将其接收到后端（云）以进行分析。然而，网关对于收获的轻能太渴了。有了典型的BLE标签，网络范围受到标签广播范围的限制，因此每个房间都需要一个网关，这意味着大型建筑物的大型建筑物（许多100-1,000个），例如机场，医院，仓库，展览中心。网络网络拓扑通过添加电池供电的继电器/锚来大大减少网关的需求，从而解决了网络的成本，不便和易于可扩展性。这些继电器接收并从最终节点和路由网络数据最佳地发送到每个建筑物的单个或少数网关的数据。他们仍然需要比最终节点更多的功率。但是，随着网格技术的最新改进以及我们在该项目中提出的一系列创新，尤其是为了改善光捕获，现在可以用收获的轻能量为它们提供动力。该项目将使绝大多数网格IoT网络的基础架构独立于电池或电源电源，从而实现低成本，可持续的可伸缩性。该拟议的工业阶段R＆D项目旨在开发基于BLE BLE的Prototype Lightype-Energy Farter-Energy Farter-Energe-direps基于BLE的Wirepas网眼媒介和双向传感器End-Nodes。人群连接将在挑战性能限制的实际环境中测试所得设备。
