One can imagine a world where a coffee maker talks to the alarm clock, a car communicates with the traffic signals, and healthcare devices share data with a physician’s system.

Though the technologies are similar in many ways, there is a fine line of difference between the two. This blog will underline the key differences between IoT and WoT and eliminate the ambiguity.

Understanding the Internet of Things (IoT)

IoT basically refers to the physical devices that are connected to the wireless network. These include mobile devices, laptops, speakers, vehicles, and even lighting. The devices are embedded with software, sensors, or other technologies that enable them to share data over the Internet. In IoT, everything is connected.

The heart of IoT lies in its diversity. From RFID tags, and QR Codes, to intricately designed smart devices, IoT combines everyday entities into a unified network.

The need for IoT

IoT has made our lives more convenient than ever. To operate more efficiently, organizations are increasingly relying on IoT technologies. IoT enables businesses to work more efficiently and make informed decisions.

The need for IoT (Internet of Things) stems from its ability to connect and automate devices. It enhances efficiency, convenience, and data-driven decision-making across industries. IoT enables smart homes, efficient logistics, and healthcare monitoring. And, sustainable resource management which makes it transform our routine lives.

The ease of IoT

Implementing IoT devices has become incredibly easy. This is why such devices have become popular across industries. Setting up smart devices like smart thermostats, security cameras, or fitness trackers is as simple as plugging them in and following a few straightforward steps on a smartphone app. This user-friendly approach means that anyone, even without technical expertise, can start using IoT devices.

How has IoT proved to be beneficial for a healthcare products company?

Kent RO used Airtel IoT to launch a video surveillance camera called Cameye. The IoT platform was needed for SIM lifecycle management. Kent also wanted the ability to categorize SIM cards based on their unique criteria.

Airtel offered an API gateway that would integrate the IoT data directly with the company’s CRM systems. This solution helped Kent to activate SIM cards, deactivate SIM cards and perform other functions directly through their CRM system.

What is the Web of Things (WoT)?

Enter the Web of Things (WoT), a novel evolution advancing beyond IoT. The World Wide Web Consortium or W3C has put in place a set of standards, referred to as WoT. It facilitates the fragmentation, interoperability, and usability of IoT. Basically, it is a subset of IoT that simplifies the connection of devices. It is created around software standards including HTTP, REST, and URIs.

The Web of Things (WoT) extends IoT by integrating devices and data into the web. WoT makes seamless device interaction possible. This way, it enables data sharing and interoperability. It makes IoT more accessible, scalable, and user-friendly for a wide range of applications and users.

The need for WoT

WoT was created to overcome the limitations of IoT. The IoT becomes complex when the number of devices connected together increases. Different IoT standards and protocols are incompatible with each other. This increases the complexity when the number of connected devices increases.

While IoT facilitates data exchange by sharing IP addresses, it doesn’t ensure that the device understands it. It is here that WoT comes in. HTTP comes with a universal protocol for transferring data. It allows sharing data in various formats including images, text, sound, and other formats. By adapting to web protocols, WoT can connect anything in the physical world and make it available over the World Wide Web.
