Future of IoT

Future of Electronics is Internet of Things but future of Internet of Things is LoRa. Internet of Things (IoT) is an emerging technology where the world is moving towards. Once upon a time we thought Embedded system is the greatest innovation because it measure, it Think, it control and it automates everything. But now it becomes very simple and the world moved to next level called IoT. Where, Internet of Things is 'Connecting of Things' together using Internet. 

What do you mean by things?

Things may be a sensor or it may be an actuator or it may be any device. So connecting of Sensors, actuators and device together using an internet is said to be an Internet of Things.

What makes the evaluation of IoT?

If you consider the embedded system, it simply measures the data and it immediately reacts for that by making some device control. But you can't measure or monitor what happened? How frequently it happens? When it happens? Or even in sometimes you may get a question that whether that particular event happened or not? So we can't able to measure, quantify or monitor the things which actually happening. So this makes the key start for evaluation of IoT. Using IoT we can able to monitor the things that what is happening? Even without our physical presence and that too anywhere from the world. Not only monitoring the device but also controls the things from your end. This makes the life simpler.

How do the things get connected together?

All the ‘Things’ can be getting connected together using cloud. Cloud is the place where the data can be stored and monitored at any time. And also it is the connecting medium of two or more ‘Things’.

Why do we connect the ‘Things’ together? 

If we want to control any devices it is generally said to be a point to point communication. Here, the major concept of IoT is that, we can able to monitor and control any IoT devices from anywhere around the world. So only when the ‘Things or connected together then only we can able to monitor and control such things. To make this communication between two or more IoT devices it needs some medium that’s what we are using Internet. So the device can connect to internet and using internet we can upload our ‘Things’ data to cloud and from cloud we can able to monitor that particular data from any devices by using internet. And that particular device can communicate to cloud using internet and it sends some data to cloud for controlling the ‘Things’ connected with internet.

In what ways internet can be provided?

Internet can be provided in any way using GSM, LAN, Wifi, USB Modems, etc., But what happen if one of your end device it doesn’t have internet connection at that particular place?

Where it fails or needs some improvement?

Just think, you are having some embedded system. It was continuously sensing some data using a sensor and it needs to be uploaded to cloud. But unfortunately you can’t able to provide internet to that particular system using any of the option mentioned above and you are in need to do automation at that particular place.

How this comes possible?

This can be achieved by using gateway integration pattern. The device can able to communicate to gateway using any of the communication technology and from gateway we can connect to cloud using internet. So the device and gateway can either connected together using a wired or wireless technology. In case, if it is a small distance and single device we can easily communicate using wired communication. But in case, consider more than 100 number of devices need to connect to a single gateway then it is not a correct way to choose wired communication. So we can go to wireless communication. But it has some limitation in its distance.

What happens if the distance between the device and gateway is more?

Each wireless communication technology has its own coverage distance to transmit and receive data. In this case, Bluetooth it covers up to 10 meters, Zigbee it communicates up to 20 meters, wifi can able to communicate up to 100 meters and it goes.

What happen if the range exceeds 1Km?

For example consider for 1Km radius around the end device we don’t have any internet facility then how it comes possible? Yes, here it come LoRa Technology.

What is LoRa?

LoRa is a long-range wireless communication protocol that competes against other low-power wide-area network (LPWAN). Compared to other communication protocols, LoRa achieves its extremely long range connectivity upto 3 Km in city area where we have less line of sight and more than 10 km in rural areas where we have line of sight, by trading off data rate. The data rates are below 50kbps and because LoRa is limited by duty cycle and other restrictions, it is suitable in practice for non-real time applications in which one can tolerate delays.

LoRa uses license free sub-gigahertz radio frequency bands like 865-867 MHz (India). LoRa enables long-range transmissions with low power consumption. The technology is presented in two parts: LoRa, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

Advantages of LoRa Technology

1. Long-range connectivity for Internet of Things (IoT) applications
