What is IoT ?

Internet of things (IoT) provides IP connectivity to various Things apart from general Desktops, Laptops and Mobile Devices. The term “things” means any physical parameter that could be sensed and connected to Internet. For example a device monitoring temperature and humidity at certain location and relaying the data will become a “thing’” in IoT domain.

Internet of things is a connecting bridge between physical world and cyber world and Machine to Machine communication i.e. without human intervention is one of the subset of it. IoT Refers to uniquely identifiable objects and their virtual representations in an Internet like structure. IoT all together a new environment in which current Internet will be smartly utilized by all new range of embedded connected things.

Sensors are the building blocks of Internet of things which can collect parameters and low power wireless embedded systems transmit information to gateway devices. Gateway device will make the parameters available over internet so that parameters are globally accessible. Till now there is no dedicated network stack defined for IoT, as it is a heterogeneous network of networks. The most popular protocols used for realization of IoT are Zigbee and 6lowPAN (IEEE 802.15.4), Bluetooth and Wi-Fi.

According To Wikipedia

The Internet of things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled.

The definition of the Internet of things has evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and others all contribute to enabling the Internet of things. In the consumer market, IoT technology is most synonymous with products pertaining to the concept of the “smart home”, covering devices and appliances (such as lighting fixtures, thermostats, home security systems and cameras, and other home appliances) that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem, such as smartphones and smart speakers.


Let’s see how different Technology giants define their Internet of things initiatives –

Cisco’s Definition of Internet of Everything:

Cisco defines the Internet of Everything (IoE) as bringing together people, process, data, and things to make networked connections more relevant and valuable than ever before-turning information into actions that create new capabilities, richer experiences, and unprecedented economic opportunity for businesses, individuals, and countries.

Ericsson’s Definition of Networked Society:

In the Networked Society, Information and Communication Technologies (ICTs) have taken us to a critical stage – an inflection point – enabling transformative and disruptive change across industries and society, catalyzing an entirely new economic model. The Networked Society promises to deliver growth and prosperity based on greater social cohesion and environmental sustainability.

GE’s Definition of Industrial Internet Of Things (IIoT):

The Industrial Internet allows you to combine brilliant machines with best-in-class analytics to deliver valuable new insights that were never before possible.  The results of these powerful analytic insights can be revolutionary for your business by transforming your technological infrastructure, helping reduce unplanned downtime and maximize profitability and efficiency.

IBM’s Definition of Internet of things:

“It’s not so much about the emergence of new technology, it’s the convergence—the ability to use sensors for everything in the world to basically be a computer, whether it’s your contact lens, your hospital bed, or a railway track.” – Harriet Green (GM, IBM Watson IoT)

Microsoft’s Definition of Internet of things:

The Internet of Things (IoT) starts with your things—the things that matter most to your business. IoT is about making your data come together in new ways. Tap into data with IoT dashboards. Uncover actionable intelligence. And modernize how you do business. Welcome to the Internet of your Things.

BOSCH’s Definition of Internet of things:

After file transfer, e-commerce, and social media, connecting things is the next generation of the internet: the Internet of Things (IoT). Connected things be anything from sensors and security cameras to vehicles and production machinery – Bosch Software Innovations expects there to be 14 billion connected devices by 2022.

According to Happiest Minds

Why Internet of Things?

An article by Ashton published in the RFID Journal in 1999 said, “If we had computers that knew everything there was to know about things – using data they gathered without any help from us – we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best. We need to empower computers with their own means of gathering information, so they can see, hear and smell the world for themselves, in all its random glory.” This is precisely what IoT platforms does for us. It enables devices/objects to observe, identify and understand a situation or the surroundings without being dependent on human help.

What is the scope of Internet of things?

Internet of Things can connect devices embedded in various systems to the internet. When devices/objects can represent themselves digitally, they can be controlled from anywhere. The connectivity then helps us capture more data from more places, ensuring more ways of increasing efficiency and improving safety and IoT security.

IoT is a transformational force that can help companies improve performance through IoT analytics and IoT Security to deliver better results. Businesses in the utilities, oil & gas, insurance, manufacturing, transportation, infrastructure and retail sectors can reap the benefits of IoT by making more informed decisions, aided by the torrent of interactional and transactional data at their disposal.

How can Internet of things help?

IoT platforms can help organizations reduce cost through improved process efficiency, asset utilization and productivity. With improved tracking of devices/objects using sensors and connectivity, they can benefit from real-time insights and analytics, which would help them make smarter decisions. The growth and convergence of data, processes and things on the internet would make such connections more relevant and important, creating more opportunities for people, businesses and industries.
