What is IoT?
  • Internet of Things simply means “taking all the physical places and things in the world and connecting them to the internet”. Kevin Ashton who is sometimes called the “Inventor of IoT” put it this way “It meant using the Internet to empower computers to sense the world for themselves”.
  • IoT is a solution to a big, real problem – the problem of knowing everything you need to know about the physical world. That could be where things are, or where customers are, or whether things need maintenance, or something else.
  • The IoT solution is all about understanding what you need about the physical world, then figure out how to get and use that information
Why Does IoT Matters? When something is connected to the internet, that means that it can send information or receive information, or both. The ability to send and/or receive information makes things “smart”. For a thing to be smart is to get connected to super storage or to a supper computer. In IoT, all things that are being connected to the internet can be put into three categories
  • Things that collect information and send it
  • Things that receive information and then act on it.
  • Things that do both.
What are the Potential Economic Impact of IoT?
  • For all the attention this emerging technology has received, McKinsey believes the hype may actually understate the long-term potential of IoT systems. They estimate that by 2025, IoT will have a potential total economic impact of as much as $US11.1 trillion per year. In fact, they argue IoT will be the biggest source of value of all disruptive technologies, ahead of mobile Internet, knowledge-work automation, cloud computing, and advanced robotics.
  • BI Intelligence estimated there will be up to 22.5 billion IoT devices in 2021, up from 6.6 billion at the end of 2016, representing $US4.8 trillion in investment from businesses and consumers.
What are the Components of IoT or Its Framework? A typical IoT system represents the integration of four distinct components: sensors/devices, connectivity, data processing, and a user interface.
  • Sensors /Devices: In the first step, sensors or devices collect data from their environment. This data could be as simple as a temperature reading or as complex as a full video feed.
  • Connectivity: Next, that data is sent to the cloud, but it needs a way to get there! The sensors/devices can be connected to the cloud through a variety of methods including: cellular, satellite, WiFi, Bluetooth, low-power wide-area networks (LPWAN), connecting via a gateway/router or connecting directly to the internet via ethernet.
  • Data Processing: Once the data gets to the cloud, software performs some kind of processing on it.
This could be very simple, such as checking that the temperature reading is within an acceptable range. Or it could also be very complex, such as using computer vision on video to identify objects (such as intruders on a property). User Interface: Next, the information is made useful to the end-user in some way. This could be via an alert to the user (email, text, notification, etc). For example, a text alert when the temperature is too high in the company’s cold storage. A user might have an interface that allows them to proactively check in on the system. For example, a user might want to check the video feeds on various properties via a phone app or a web browser. Where are the Potential Application Areas of IoT?
  • These are areas where IoT brings benefits or vales to the customers. Global Consulting firm McKinsey has set out a list of potential uses for the Internet of Things (IoT) and where the IoT could add value.

Classification of IoT Solutions
  • Consumer IoT: This refers to things like wearables, ingestible, smart home devices, etc., all of which are marketed directly to consumers.
  • Enterprise IoT: Enterprise IoT refers the use of IoT in improving an organization’s existing systems and processes and enabling organizations to increase operational efficiency or unlock entirely new value. (e.g. by launching new business lines or products)
What are the Careers Opportunity in IoT?
  • Data analytics: One of the key features of an IoT system is the amount of data generated. With the sheer number of devices involved, and nothing to make sense of it, it’s as good as a pile of junk. Data Analytics are in high demand within the IoT industry with expertise in both structured and unstructured data.
  • Networks and Architecture: An IoT system can be viewed as a complicated mesh of connected gadgets and objects that ultimately makes no sense if it is not planned properly before implementation. Due to the wide variety of implementations being done and will be possible in the future, there are different types of sensors and transmitters that communicate differently within the system. This is where the network specialisation would come in. There will be a broad array of methods of communicating data.
  • Cyber Security: With the sudden explosion of device and sensor implementation, the industry has only now realised that all that data and all those devices also need to be protected from malicious external sources
  • Device and Hardware. Hardware engineers are the people who actually put together the various components available to manufacture the device in terms of design. The same is applicable to IoT as well, albeit with a large number of sensors and transmitters.
  • Mobile and UI development: The IoT boom has come at a time where our lives are closely integrated with smartphones. And since the whole point of IoT is to connect everything all-the-time, smartphones and mobile devices are ideal candidates for the platform of choice to control IoT devices.
