IoT Then & Now

IoT Then and Now

One of the most significant IT innovations in recent years is the IoT. In our daily lives, all of us rely on a range of technologies, which is everywhere, from waking up to a mobile alarm clock to playing music by uttering ‘Alexa’; but how did it all begin? How far has it come? What will the future hold for it? What is the role that IoT app development companies play in it? Let’s see…


The timeline of significant events in the growth of IoT is depicted in the infographic from HQ Software. Kevin Ashton, co-founder of MIT’s Auto-ID Centre, is credited with coining the term in the 1990s. His concept was to connect devices using RFID technology. Nowadays, the IoT service providers predominantly use IP networking to communicate between devices.

The RFID concept proposed by Ashton failed to gain momentum. Instead, in 2000, the first internet-connected refrigerator was released, which used a LAN connector to connect to the internet. More information about that, as well as other devices that came in the 2000s, can be found in the Wikipedia entry.

Some claim that it really took off in 2009, when Google started testing self-driving cars. A year later, China emphasized the IoT as critical to addressing financial difficulties. In 2015, the Global Standards Initiative was established, and governments began to consider IoT security in 2017.

Hype Cycle for emerging technologies, 2018


In 2019, there were 9.5 billion active IoT devices, which was substantially larger than expected. IoT connections grew in 2020 because of the use of laptops & computers.

From thermostats to autos, all types of gadgets are now connected to the internet. Many things have contributed to this, including the growth of networking capabilities. The rise of the cloud has been maybe the most important cause. IoT devices have since grown far less expensive, with cloud servers providing massive storage capacity.


According to Statista, by 2025, the total number of installed connected devices will be 75.4 billion worldwide. This represents a fivefold increase since 2015.

These figures suggest that the future of IoT development services will be more innovative and revolutionary than the present. It seems inevitable that IoT will be adopted by a growing number of domains. Let’s look at some of the IoT trends that will shape the future:

  1. 5G integration:

Existing networks’ capabilities would be greatly enhanced by 5G. The current network would not be replaced by 5G, but rather enhanced. 5G, whether old or new, would allow for lightning-fast data transmission to and from cloud servers.

  • Single interface:

As previously stated, an increasing number of devices with various capacities are joining IoT networks every second. Instead of a basket of remotes and interfaces, individuals and businesses would require a single interface that allows end-to-end access.

  • Multi-level privacy and security

Data privacy and security will become increasingly more critical. Data security has traditionally been implemented at the device level, whether it’s a smartphone, laptop, or other smart device connected to an IoT network. Privacy and security protections will be introduced at several tiers between IoT endpoints in the future.

  • Shift from products to services ecosystem

The data generated by any IoT system is its primary driver. Companies that produce products would gradually shift to delivering services based on data insights.

Advancements in three technologies; Cloud Computing, Big Data, and Artificial Intelligence have aided the rapid rise of IoT. The IoT appears to have a bright future. 5G is poised to significantly disrupt the IoT by bringing high-speed transmission capabilities to both existing and future IoT networks.
