Characteristics of IoT (Internet of Things)

The Internet Of Things or IoT has appeared to be a transformative force in the technology domain. IoT has enabled many businesses to manage, monitor, and automate their operations with more control and in an efficient way. There are numerous key characteristics of IoT that establish a standard of innovative services and autonomous operations across numerous industries. 

However, before we begin with the characteristics of IoT, Let us quickly discuss What the Internet Of Things (IoT) is, how it works, and the importance of IoT. 

What Is IoT (Internet Of Things)? 

IoT is a network of interrelated devices such as physical devices, appliances, vehicles, or other physical objects that are rooted with software, sensors, and network connectivity intended to connect and share data with other IoT devices over the internet.

There are more than 10 billion connected to IoT devices and is expected to grow to 22 billion by 2025. IoT has a significant impact on our lives by automating household tasks making a smart home to industrial applications that help in monitoring and optimizing manufacturing processes. IoT has transformed various industries including healthcare, manufacturing, transportation, and energy. 

IoT enables persistent integration between the digital and physical world by utilizing the power of machine learning, artificial intelligence, and big data analytics. IoT also helps in transferring data through a network that does not require interaction between human-to-human or human-to-computer. 

Sensors that are inserted into the physical object will collect and transmit data from the cloud from where it is processed and analyzed. The information gathered empowers businesses to make informed decisions, optimize processes, and also to deliver better services to their customers.

The perfect blend of software advancement, physical design, and intelligent algorithms has paved a path of possibilities for boosted efficiency and convenience. Some examples of Internet of Things (IoT) Includes:

  • Connected cars.
  • Smart appliances.
  • Connected security systems.
  • Smart agriculture equipment.
  • Connected retail.
  • Connected healthcare monitors.
  • Connected manufacturing equipment.
  • Connected cities.

How Does IoT Work?

The important aspect of IoT systems includes sensors, software, and network connectivity technologies for the purpose of collecting, sending, and acting on the data they gathered from their context. 

Sensors are in charge of collecting data from physical devices and they are able to measure humidity, motion, temperature, light levels, and many more. IoT devices then share the collected sensor data by connecting it to an IoT gateway- which is a hub in which IoT devices share data. 

Before sharing the data, they can also be sent to an edge device for the purpose of analyzing the data locally. This is to minimize bandwidth consumption by reducing the data volume sent to the cloud. 

The collected data needs to be transmitted and shared – That is when connectivity technologies play their part. The technologies permit these devices either to connect to the internet or communicate directly with one another within the local network. Some of the examples include Bluetooth Low Energy (BLE), Wi-Fi, and cellular networks like 3G, 4G, or 5G. 

There are times when the device communicates with other devices that are related and act based on the information they receive from one another. Most of the work done by the devices is without human intervention. However, humans can also interact with the devices, for example, setting up them, accessing data, or giving them instructions.
