In the Internet of Things, you can communicate with inanimate objects and they talk to you too. Sensors collect the required data – temperature,humidity, ambient light, speed,engine wear and tear, inventory levels, etc. – and share it with the cloud using wireless or wired communication protocols. https://www.embitel.com/product-engineering-2/mobility-iot/iot-services

In the Internet of Things, you can communicate with inanimate objects and they talk to you too. Sensors collect the
required data – temperature,humidity, ambient light, speed,engine wear and tear, inventory levels, etc. – and share it with
the cloud using wireless or wired communication protocols. But this collection and sharing of data is only the beginning of
an amazing chain of sequences that’s making everything come alive these days.
It’s the gateway that makes these ‘things’ connect to the Internet, acting as the nervous system of the entire IoT ecosystem.
True to its name, it acts as a gate/bridge between the ‘thing’ and the back end cloud or server infrastructure by wrapping
the data into packets that can be easily processed by your back end infrastructure. The gateway plays a vital role in bringing
sensors and legacy devices to the cloud.
Devices with different physical properties can be connected to the internet, even while using the existing hardware system.
Whether it’s controlling the temperature or lights of your home, automating the machines in your factory, or monitoring the
status of various parts of your car, without the sensors and gateway none of this is possible.

Gateways for the Internet of Everything
The type of sensor and the gateway protocols that need to be designed and deployed depends on the application. Here are
some examples:
• Smart home automation – This usually involves automation of lights, temperature, entertainment systems and security.
Home automation can be implemented using wired or wireless sensors, depending on one’s need.
• Smart factory automation – The factory floor usually requires coverage of a large area and needs large capacity, so the
gateways usually use wired protocols like RS482 and profibus to get connected to the sensors.Depending upon the
factory environment, wireless protocols like Zigbee or the energy-harvesting EnOcean sensors can be used. Sensors for
factory automation should be chosen carefully considering parameters in the deployment area like temperature, dust
levels, noise level, radiation levels etc.
• Vehicle automation – For vehicles, the gateway uses a modem with 3G or 4G connectivity , or a connection is
established through Bluetooth tethering or a Wi-fi hotspot with mobile internet. Protocols such as CAN, LIN, FlexRay,
Ethernet etc. are used to capture data like speed, vehicle health parameters, fuel level, tire pressure and more.

But to put a gateway to best use, you need a tech partner who can customize it to suit your requirements. “There’s almost
no end to the level of customization possible on a gateway,” says Sujith V., senior software engineer in Embitel’s IoT team.
Sujith and his teammates, who have built gateways solutions in Android and Linux, have been able to design custom
gateways compatible with Zigbee, EnOcean, BT, Modbus, Profinet and more. They have also designed gateways for different
levels of complexity – from automating an office room to an entire building or retail inventory automation.
With increasing implementation of IoT in various spheres of life, the need for a well-orchestrated interplay between sensors
and gateways is apparent. A technology partner, with the right knowledge and experience, can deliver a well-designed
gateway and related protocol solutions to reduce time-to-market and help you deliver a state of art IoT experience to your
customers.
Decoding How IoT Works: Cloud & Mobility
This is part 2 of our series on decoding the components of the IoT ecosystem/set-up. The data flow starts when sensors
fetch raw data from your devices and send it to the IoT gateway, as explained in Decoding how IoT works : Sensor Networks
and IoT Gateways. Here is what happens next.
From the gateway, this data is sent to the cloud, where it’s made actionable, and finally to your mobile or desktop.

The cloud is an amazing thing—besides storing data, it’s where sense is derived from all this information, which can be then
put to use, and you can give commands from web dashboard. How does all of this happen, and how can you make it work
for you? Embitel’s experienced engineers explain.
Software engineer Omprakash Punumalli terms the cloud as the ‘brain’ of IoT. “Communication can happen (with some
restrictions) without the gateway, but all data processing happens because of the cloud.” Raw data is transmitted to the
cloud through MQTT protocol, on which machine learning algorithms and other big data analysis is performed, and
information is derived.
What time are the lights switched on every day, at what temperature is the AC set regularly, how many hours has your
appliance run, how much longer before the device is due for servicing—these are some of the useful pieces of actionable
information the cloud can derive from the data, and make predictions for you.
This information is then transmitted to the mobile app or web dashboard using RESTful APIs and JSON query. “An adept
engineer can apply the right algorithms or even write new ones to help you make the best use of the data in cloud, best
suited to your needs,” says Om.

Mayank Joshi specializes in working on mobile applications for IoT. “The app is not only a platform for the end-users to
connect with, control and monitor the devices, but it is also the only touch-point to perform tasks like sending push
notifications to users, and implementing location and proximity specific features like beacons,” explains Mayank.
Embitel’s team has succeeded in designing apps that have a universal look and feel across different devices (mobiles and
tablets) and versions of the devices. The apps support a variety of features.
One can group events to run in tandem, such as turning off the lights at 5am, while turning on the hot water, opening the
blinds and playing soft music—all aligned to, say, ‘good morning’ mode. One can equip them with beacon technology, so if
you’re a garment retailer, your customer (who has your app on his phone) is alerted about the new discounts in the store
when he comes within a specified proximity. If the cloud has gathered data on the run time of your appliance, the app will
display a warning as the end of its life draws near. So while the primary role of the app is represent information, the kind of
information it disseminates and the timely push notifications it can provide make all the difference.
