![]() Power refers to the overall need for device power consumption within the system. Mobility defines whether devices are physically fixed or mobile. Keep in mind that throughput requirements could differ depending on which part of the system we’re talking about. Throughput is the maximum data rate supported by connections between devices within the system. We define range as the maximum distance at which a reliable connection between two devices within the system could be achieved. Device-to-Cloud: Devices within the network need to communicate with a cloud-based backend server.Device-to-Gateway: Devices within the network need to connect to one or more gateways within the system.Device-to-Device: Devices within the network need to communicate with each other.In this context, we are considering the following types of communication models. The communication model describes the requirements for communication from end devices in a system. The most important attributes of an IoT system include: Communication Model An attribute is a property that defines the behavior of devices within an IoT system and how they interface and interact with each other. Now let’s define what we mean by an attribute in this context. Cloud: Refers to a public domain network (the general internet) or a private domain network, such as in cellular networks.The gateway in this scenario would be used to bridge the Bluetooth connected door locks to the internet or a local Wi-Fi network. For example, a gateway may be installed in a building that has a dozen Bluetooth ® enabled door locks installed. ![]() Gateway: A device built with the purpose of bridging two or more networks (that normally cannot communicate with each other).Examples include smartphones, connected light fixtures, connected sensors, door locks, and smartwatches. Device: A piece of electronic equipment capable of wirelessly communicating with other peers within a network.For simplicity, we define IoT as the capability of devices to communicate with each other over one or more wireless networks. IoT (Internet of Things): There’s a lot of confusion around this term, and you will likely see many, sometimes conflicting, definitions.Some of the most common types of industrial and commercial applications include:Ĭondition Monitoring Sensor Networks: For example, a system to monitor the status of machinery in a factory.Ĭontrol and Automation Systems: Commercial lighting, security systems, video cameras, etc.Īsset Tracking: For example, tracking locations of medical equipment/devices in a hospital.īefore we go over the list of attributes of an IoT system, let’s define the different terms that will be used in this series. In this article, we’ll focus on the most popular IoT applications in the industrial and commercial space, define the terminology we’ll use throughout the series, outline the most important attributes that affect the choice of wireless technologies for an application, and identify the most popular candidates for wireless connectivity that will be discussed in the series. Naturally, the requirements of a project depend on the type of application in question. In the end, the final choice of a connectivity technology (or technologies) for a project comes down to the needs and requirements of that specific project. When it comes to wireless connectivity, an IoT developer has a slew of options to choose from, but not every technology is fit for a specific project, and no technology is a one size fits all. The following article is Part I in a series on wireless connectivity options. ![]()
