The Internet of Things

The Internet of Things (IoT) sounds like a futuristic concept. But it's already happening all around you. Internet-based maps are pulling anonymous data from motorists' cell phones to record real-life driving patterns and provide accurate travel time information. Doctors are using portable monitoring technology to keep track of their patients' health. And it's not unusual for homeowners to control the thermostat, lights, or other home features from their smartphone.

Billions of devices are already linked to the Internet, and the number continues to skyrocket. These connected devices are communicating with each other or a data cloud and providing an unprecedented array of services and information. And there's new applications for IoT being thought up every day. Mouser provides the latest devices from Intel, Freescale Semiconductor, Altera, Nordic Semiconductor, and other leading suppliers to help designers on their way to creating the next intelligent design that further expands the ever-developing IoT.

IoT Overview

The IoT is generating unprecedented opportunities for developing new services, enhancing productivity and efficiency, improving real-time decision making, solving critical problems, and developing new and innovative user experiences. For example, wireless sensors on cattle and other livestock could send a message to a rancher when an animal is pregnant or ill. A wireless heart monitor could let doctors remotely gauge a patient's health. Such intelligent devices and "things" rely on intelligent communications systems and networks that make it easy to send and receive secure data. Another crucial element of the IoT is being able to analyze and interpret the wealth of intelligent data and apply that information to solving problems or providing services.

IoT Services

The Internet of Things means different "smart" services and technologies that will be used in many everyday situations (see above infographic). The technological innovations it offers include miniaturization and advances in packaging technologies, advances in flash, a new class of powerful, yet low-cost and low-power, processors, and an ever-expanding range of cloud-based services.

Intelligent Devices

Name a household appliance, machine, or other thing consumers use regularly -- their car, an insulin pump, a washing machine ... any physical object. These devices when embedded with sensors and microprocessors are gaining the ability to sense their environment and communicate with computers or other intelligent equipment. And these intelligent "things" are sending signals and information without requiring human input. Designers are working to make devices more intelligent but also performing the vital task of ensuring the information is secure and can be reliably filtered and managed.

Wearables: One class of intelligent devices that stands to impact many consumers' daily lives is wearables. Wireless-enabled wearable devices have sensors tracking calorie burn, body mass index, or even sleep levels. Cloud-based wellness programs are interfacing back and forth with wearables, allowing for self-monitoring, management, and data sharing with healthcare providers and others.

Digi Semi IoT Diagram

Different types of devices comprise different types of networks that can communicate with a variety of applications over the Internet (see above infographic). These applications may have multiple interfaces. These device networks connect with the Internet and then communicate with the applications through a backhaul network. This backhaul network is the communications backbone of the Internet infrastructure.

Remote Patient Monitoring Example
Freescale Remote Patient Monitoring

Medical devices of all kinds are getting smarter and better connected, enabling the transmission of data that can be compiled and analyzed. Doctors can, remotely or in a hospital, leverage that data to make better-informed decisions to direct patient care more quickly and efficiently than ever before. The essential processing technologies are becoming pill-sized to speed this evolution along.

New Ideas Thanks to IoT
New Ideas Thanks to IoT - from Intel

The Internet of Things is allowing for a broad range of new possibilities, including digital locks in which you can grant or restrict access to a door using a few rapid keystrokes on your phone. Smart buildings are another innovation. These fully networked structures let owners and occupants monitor various aspects of a building that determine comfort or energy usage.

Intelligent Communication

Connectivity is critical to unleashing the power of the IoT. Systems of intelligent devices must be connected to each other or to a network to send and receive secure data. Sophisticated cloud-based processing can help facilitate this connectivity but requires a new generation of communications processors that can keep track of connected devices, communicate with them, and translate their functionality into useful services. Gateways and hubs aggregate data from intelligent devices and pass the information across a network.

Data is communicated from smart devices on a local level through Body Area Network (BAN), Personal Area Network (PAN), and Local Area Network (LAN) communications that may adopt a number of current and proposed wireless protocols optimized for a different mix of power use, bandwidth, cost and reliability. Wide Area Networks rely on technologies such as Ethernet or up-and-coming technologies such as the Weightless Standard. Cellular technology also has a role for WAN coverage, but only when available.

The Various Layers of the Internet of Things
The Various Layers of the Internet of Things - from Altera

The Internet of Things actually comprises at least three layers, each with its own medium and protocols. Specific applications may require considerable local processing in the hubs. The outside layer of this network comprises the things -- physical devices that touch (or almost touch) the real world. These include sensors -- optical, thermal, mechanical, and so on -- measuring the physical states of houses, machines, or people. But this level also includes some complete control systems, such as thermostats, smart appliances, or drone helicopters. The presence of these more complex devices introduces a debate posed by the IoT: What is the actual first level: sensors and actuators, or complete systems?

Today's Wireless Landscape
Today's Wireless Landscape - from Freescale

Numerous communication topologies exist today, from wireless body area network to wide area network and all of the options in between. Many of the companies offering wireless and wired solutions are positioning their products as "the communication engine of choice" for the IoT market. IoT will also add the concept of wireless sensor and actuator networks, which are networks that contain sensing and embedded processing nodes that can control their environment.

Current Communication Technology
Communication Technology - from Freescale

Bluetooth® Low Energy is being adopted by the health care industry for portable medical and lifestyle devices. ZigBee® and low-power Wi-Fi® technologies are competing for the industrial control and automation marker. Wi-Fi technologists are already using 802.11ah (Wi-Fi on ISM bands below 1 GHz) to tailor it for infrastructure independent ad-hoc, mesh networking, and longer-range control of sensor networks. There could also be brand-new technologies better suited for certain aspects of IoT communication that displace the existing standards for the IoT.

Intelligent Analytics

The enormous volumes of data generated and shared across intelligent devices and systems need to be analyzed, and the value extracted from the information to serve a business's needs. This allows companies to offer better products and services, enabling new business models and enriched consumer experiences.
