What is Telematics?
Telematics is a problematic auto innovation that uses IT and correspondence conventions to send, get and
store data relating to distant vehicles. The information is communicated over a remote organization
through secure methods and an in-vehicle electronic gadget or cell phone is utilized for building up far off
availability.
In this article, we investigate the different aspects of telematics and the central issues to consider while
building up a telematics framework.

When we say that a vehicle is integrated with telematics, it essentially means that it is fitted with a crash-
resistant black box with a complex electronic control unit inside. This black-box, also referred to as the T-
Box in automotive engineering parlance, is a telematics control unit.
Telematics Control Unit & IoT Cloud Connectivity
An automotive telematics solution fundamentally has four building blocks:
• Vehicle ECU Network
• Telematics Control Unit (TCU)
• IoT Cloud Server
• Telematics Applications
How Does Telematics Work?

Embitel Technologies International presence:
A vehicle’s telematics system can have a Telematics Control Unit or a Telematics Gateway Unit (TGU) based
on the functionalities that the system is expected to perform.
1. Telematics Control Unit – A Telematics Control Unit is designed on a Microcontroller Hardware
Platform. It is a low-power solution with low memory footprint. It also offers low data throughput. It
can store offline data only for a small period.
2. Telematics Gateway Unit – A Telematics Gateway Unit has a high-performing Application Processor
Hardware Platform at its core. It offers various advantages when compared to a TCU. This includes
higher data throughput and capacity to store offline data for a longer time.
