what is Internet of Things?

In short, IoT are the control, management, and awareness of the environment that we intend to control. However many phenomena and events are out of our control and their lack of timely awareness can have irreparable damage to us. IoT uses various sensors to investigate various phenomena and report data to the Control and Processing Center using data transmission technologies. The Center for Control and Decision Making takes many forms. This control center can be next to the same sensor or somewhere else away from the sensor and even to one center at one point on the Earth.

In the world of Internet of Things, what should we do?

This is a question many people ask me. Let me tell you clearly. All people in the world need the Internet of Things. Are you at home sitting on the couch in front of your TV watching your favorite program? You may be interested to see your young child sleeping on his bed in his room or playing with his toys. Or you might want your brewed coffee to have a cup of coffee, or even wash your dirty laundry.

Is your room temperature right? With cameras installed inside and outside your home, you are sure that you can keep your living space safe at any moment. Do you want to take a look at your workplace and not get bored getting up from the sofa? These examples and thousands more make us think of the Internet of Things. Isn’t it time to move on with the technology world and change our world? I think we need to wake up and take a step forward and bring this technology into our world and enjoy it.

What do I need to get into the world of Internet of Things?

The answer to this question is very simple. First, You have to change your mind. Think of these changes, accept them, and then bring them into your life. Scientists have brought technologies to humankind to make human beings more prosperous. IoT is one of the achievements of scientists will change our lives today and tomorrow.

Secondly, you will have to arrange things inside your home so you can control them remotely. Ask your vendor today if you are buying any device whether it can connect to the Internet of Things. Thirdly, it’s time to install the device. Install them yourself if you can find some training in this area. If you do not have any training on how to install it, consult a consultant. Once installed and used, you’ll be sure to enjoy it.

Finally, after installing and using the first IoT device, develop your IoT and try to get more IoT knowledge day by day. Babolifes is trying to make you familiar with IoT knowledge step by step. Enter the world of IoT with Babolifes products, install them and enjoy life there.

Internet of Things Components

Internet of Things Components

What are the components of IoT?

In general, IoT architecture consists of three parts.

  • Device
  • Gateway
  • Data system

Devices in the Internet of Things

Devices are the part from which we extract data. We divide the equipment into two parts.

  • Hardware
  • Software.

Hardware is everything that exists in the world around us. We start with home and workplace hardware such as lighting, cooling and heating, kitchen appliances and home security cameras. Logistics such as road transport, traffic, sea transport, shipping, air transport, rail transport. Industries and factories are extensively in production lines, quality control, warehousing. In medicine, many medical devices nowadays are able to connect to the Internet of Things.

In the software sector, many accounting, warehousing, finance, customer relationship management, energy and consumption issuance, diagnostics and information and many existing software generate data for the IoT.

Gateway in the Internet of Things

The gateway is the place for data entry into the internet world. However, the data moves to the data center where it is processed and stored. Let me talk a little deeper at this point. All data coming into the Internet platform is in a specific format to the Internet network. This is called the packet format. Packets are transported under certain protocols. Because some protocols have different lengths and data rates are very high at the same time, much power is needed to transmit data, which is not suitable for IoT data. So at this point we have other protocols. We will discuss these in future articles.

Data system in the Internet of Things

Data systems include data centers. In these centers, a lot of data comes in and out. Suppose you are going to ask your child’s nurse about a child with a Babolifes product such as a IP Surveillance Security Camera 1080p HD at your office. Here your data is your child’s room picture frames. This data cannot be imported directly to your mobile phone from home, but data will first enter data centers and then come to your phone.

Data center processing is your baby’s image processing and storing your data. The location of the data center is very important. Your phone is connected to the nearest data center and your home is connected to the nearest data center to your home. So there is data transfer between these two centers.

Data transfer technology

There are various ways to transfer data from IoT sensors to the control and processing center. These methods depend on the data transfer environment. Sometimes we can do data over a wire or a route, and sometimes through wireless technology. In this case, we use the standards and protocols of short-range wireless networks. If the control and processing center is far from the sensors, we can transfer data over the Internet. So in this case, we use the standards and protocols of the Internet network.

Wireless data transfer technology in Internet of Things

Today we use this method of data transfer in many of our communications. IoT is also used for data transfer in environments like smart home, smart city, smart car and smart office. For example:

  • GSM and LTE: For telemetry, smart city and remote control
  • Bluetooth and WiFi: For smart home and smart office
  • Lora/LoRaWan & SigFox: For telemetry, energy metering and smart city

GSM:

GSM is the second generation technology of wireless phones. However, extended type of 2G network This technology is GPRS. GSM uses the 900 and 1800 MHz frequency band to transmit voice and message data. The GPRS network also uses a 2500 MHz frequency band and can transmit data using the IP and WAP protocol. In both cases the data transfer rate is 20 kbps. With the advent of 3G technology, the third generation mobile phone came on the market. The frequency band used by this technology is 2100 MHz. It can reach speeds of up to 14.4 Mbps.

4G(LTE):

4G technology is the fourth generation of mobile technology. Data transfer speeds in this technology are ten times higher than those of the previous generation. Its frequency band is 700 MHz and 2600 MHz and data transmission speed is 75-250 Mbps. The technology is designed to use high-speed Internet on mobile phones.

5G:

This technology, also referred to as the technology revolution, is now the latest generation of mobile phones. Its frequency band is 26 GHz to 95 GHz and the data transfer rate reaches 10-20 Gbps. We intend to talk to you in detail about this technology in the near future.

Bluetooth:

This technology is designed to connect electronic equipment in the short distance, and it can be used to connect to the gateway. Its working frequency band is 2400 MHz and can transmit data at a maximum speed of 24 Mbps.

WiFi:

The WiFi network is dedicated to transmitting data over WLAN networks. Its low bandwidth and frequency band are 2400 MHz. Data transfer speeds are at best 150 Mbps. The technology is now widely used to transmit data across mobile networks, laptops, computers and the gateway connection.

Internet data transfer technology in Internet of Things

As the scope of IoT applications in the real world grows, newer problems arise and new solutions emerge. Engineers and specialists offer different options depending on the technology requirements. Each of these options creates different standards and protocols on the IoT. In the past we have known consistent solutions for transferring information. The standard TCP/IP networks we’ve been using for many years. And we still use them extensively. The main issue with using these types of networks is their inefficiency at some times and their high energy consumption. So professionals are looking for alternative solutions to deploy this technology. Here are some of these solutions.

Long Range Wide Area Network (WAN) solutions

Narrow bandwidth in Internet of Things 

NB-IoT new technology is a low-power wide-area network (LPWA). It generates very low power radio signals and produces high power signal connections so it is suitable for long range transmission. The battery life used in some cases can be up to ten years. Narrow-band IoTs are compatible with existing network infrastructures and guarantee universal coverage of quality signaling. The only problem is its low data rate.

LTE-Cat M1

LTE-Cat M1 technology, like the NB-IoT, uses a low-power wide-area network (LPWA) standard, but it is suitable for medium data transmission rates. It also does not require new infrastructure and is suitable for use on mobile phones.

Engineers designed the third technology to expand the long-range van networks. The technology also has really low power consumption and can support up to several million users. Ideal for smart city projects because it supports low-power bi-directional communications.

LoRaWAN

LoRaWAN technology also has a low data rate but its energy consumption is really low. The technology consumes 100 times less power than cellular and mobile modes, and the battery life can be extended to 20 years. The signal is also strong enough to be used in smart city projects for smart street lighting, patient monitoring, physical security and smart meters.

Conclusion

IoT is expanding day by day. Every day more and more hardware and software are used. The world around us is becoming more intelligent, and human needs have taken on a new form. So we need to find newer technologies to meet this growing need. Technologies that drive us to consume less energy and increase productivity.
