Descriptions

This training is the most detailed hardware training available on the platform. It is all about system design for Internet Of Things applications using cellular connectivity.

This training goes beyond just PCB design. It covers all the things that a hardware design engineer has to follow in their professional life to create a product.

The hardware taught in this training is based on a microcontroller from ST Microelectronics which is most widely used by professionals in industrial applications. For cellular connectivity, we will be using a 4G LTE Modem from SIMCOM.

Why should you take this training

High industry demand

Internet Of Things based products and their demand is increasing every day. Because of that, the demand for the people responsible for creating them is also increasing.

Industries want to connect their processes or products to the internet, to remotely monitor or control them. To achieve this they need people who can help them automate the process.

If you enjoy building an IOT product & want to work in electronics product development companies, then this training will help you achieve your goal.

It’s everywhere

2G, 3G or 4G cellular connectivity based devices are everywhere. Industries in domains like Automotive, media, petrochemical, consumer appliances or medical industry are heavily dependent on IoT.

Some of the examples of cellular connectivity based devices are

• a.

  Vehicle tracking Unit (VTU) or GPS trackers used by transport companies like Uber, Ola etc

• b.

  Wireless camera or IP cameras for remote monitoring

• c.

  In-built IoT systems in cars for vehicle telematics

• d.

  Remote monitoring or controlling devices used in industrial automation

Increasing future value

The total installed base of IOT devices worldwide is projected to be around 30 billion units by 2025. The demand for hardware designers and firmware developers is increasing day by day.
