The goal of the project is developing a low-power Internet-of-Things (IoT) enabled smart sensor node that is capable of generating, processing, and storing locally generated sensor data (i.e. position, identification, sensory info, etc.) and communicating through optical means to an optical wireless communication (OWC) hub.
Problem Definition[edit | edit source]
event 5G will provide extended wireless connectivity and capacity, it is expected that massively deployed IoT devices will require data traffic that would not be met by only RF based wireless technologies. The wireless connectivity based on wide optical bands, termed as Optical Wireless Communication (OWC),is considered to be promising solution for the development of high density and high capacity 5G and IoT networks of the future. In comparison to RF-based networks, OWC-based network technologies offer unique advantages such as high data rate, low latency, high security, and low energy consumption without interfering with RF communication channels.
Background[edit | edit source]
The life of a citizen of the early 21st century takes place simultaneously in physical and cyber space. In couple of years more than 50 billion devices will connect more than 7.6 billion people with exponentially increasing connectivity demand. As the demand for data heavy wireless applications and services are increasing, the RF spectrum will get more congested resulting in slower wireless browsing or worse. This necessitates communication service technology to shift from fourth generation (4G) to fifth generation (5G). It is expected that the 5G will be deployed many part of the world by 2020. Comparing with the 4G, the 5G will offer new services with high quality of services (QoS) and quality of experience (QoE), high user capacity (1000x), higher data rates (100x), lower power (10x), and lower latency.
Deliverables[edit | edit source]
Figure 1. Envisioned IoT enabled sensor node with Optical Wireless Communication (OWC).
Minimum expectation is to design and verify a compact IoT enabled optical transceiver sensor nodes that could respond to commands received from OWC hub in visible spectrum, achieving up to 10m optical wireless communication (OWC) distance and more than 100Kb/s upload data rate with less than 10-3 BER as shown in Figure 1. Transmitter unit has to be able operate with off-grid power sources (i.e. battery) for extended period of time (i.e. weeks), and should be compact enough to be deployed remote locations. The unit should have smart processing (i.e. MCU), storage (i.e. store sensory data every hour for a month), and integrated sensor(s) (i.e. temperature, humidity, etc.). Available development
