Definition, use cases, all about this technology?

Over the past few years, analysts have pointed to the rapid growth of the cellular Internet of Things. In fact, Ericsson says that by 2023, of the 20 billion IoT devices, more than 3.5 billion will run on a cellular network.

L ‘The Internet of things (IoT) connects over consumer products such as wireless speakers and smart lights. The majority of these connected organisms depend on cells. But what is cellular Internet of Things and how is it different from consumer connectivity? Discover the advantages of this nomadic network and the different types of cellular connections used in the Internet of Things.

Cellular Internet of Things: Definition

Cellular Internet of Things Uses mobile networks to connect physical devices to the Internet. This connection allows these devices to transmit and receive data and integrate it into the Internet of Things. In fact, the cellular Internet of Things is the most popular type of connection, mainly because:

  • Provides excellent coverage
  • Simplifies global publishing
  • Works right out of the box
  • Establishes a more secure connection than other shared networks
  • Works well in mobile, indoor and outdoor applications
  • Supports low and high bandwidth.

Like smartphones and other mobile devices, cellular Internet of Things It is based on LTE-M, NB-IoT 2G, 3G, 4G, 5G and Low Power Wide Area Networks (LPWAN) technologies. To transmit and receive data.

Cellular Internet of Things: Use Cases

The cellular Internet of Things is Well suited for a wide range of applications in indoor and outdoor environments. It is used in everything from self-driving cars and smart parking to self-driving agricultural equipment and consumer devices such as smart watches.

In fact, the cellular Internet of Things is so pervasive that if a device is used in a B2B application, it It probably depends on the cellular connection. Overall, it is ideal for logistics, manufacturing, asset tracking, supply chain management, emergency services, healthcare, and security.

In fact, cellular communication of IoT devices Provides the ability to send and receive signals from anywhere in the world. With 5G networks, mobile network operators (MNOs) can do just that Perform real-time data transfers while moving at high speed.

The biggest limitation on cellular connectivity has always been battery life and power consumption. But Low Power Wide Area Networks (LPWANs) and advances in technology save energy when not in use. In addition, modern cellular sensors can transmit small data packets without consuming a lot of power.

Cellular Internet of Things: How Communication Works

Cellular connectivity depends on several key components. To better understand this concept, one must Learn the basics. Including SIM cards, modems, frequency bands and mobile network ratings (2G, 3G, 4G, 5G, Nb-IoT, LoRaWAN).

IoT SIM cards

Like smartphones and other mobile devices, IoT devices Need a SIM card to connect to a cellular network. However, unlike a smartphone, an IoT device does not have to be limited to a specific network of the resource. Therefore, the latter must Plan to use SIM cards that are not connected to the network. This allows devices to connect to any system with the best coverage.

modems

using a modem Simplifies the development and certification of the Internet of Things. The selected SIM card identifies the provider’s networks. Therefore, the specific modem affects the frequency ranges with which the device can communicate.

Frequency bands

Frequency range is Range of frequencies in the radio frequency (RF) spectrum. It ranges from 30 hertz (Hz) to 300 gigahertz (GHz). Cellular uses a small portion of the spectrum between 800MHz and 5GHz for 2G, 3G and 4G connections. The 5G network can use bands of up to 35 GHz.

Cellular feature

its cellular networks Several main factors that make it so popular with IoT manufacturers. When it comes to convenience, coverage, and security, it’s hard for other connectivity solutions to compete with cellular networks.

global coverage

For large-scale global deployments, cellular connectivity M2M generally comes out as the most reliable and cost-effective method of communication. In fact, there is no need to build a new infrastructure for every new deployment. Just connect to an existing network.

Moreover, the cellular Internet of Things presents itself as Wide Area Network (WAN). he is Allows you to connect globally Through radio waves sent and received by cell towers. In comparison, a WiFi connection requires the device to remain very close to the access point/router, which prevents commuting over long distances.

Integrated authentication

Cellular networks use SIM cards for Authenticate devices, associate them with a legitimate subscriber, and provide a secure connection. Hackers can spoof IP addresses. However, they cannot hack the subscriber identity stored on the SIM card.

Types of Mobile Networks Used by Cellular Internet of Things

Over the years, cellular networks have grown faster and stronger. But for IoT manufacturers, power and speed are usually not the main factors to consider.

The next generation of cellular networks It can also mean more power consumption and fewer caps. In addition, the system used will affect the range, coverage, frequency, power consumption, cost, and longevity of the equipment.

Most users have at least heard of the terms 2G, 3G, 4G and 5G networks. However, to meet the needs of most cellular IoT devices, Carriers have also developed other types of networks that may seem less common. Here are some of them

5G networks

The 5G network It is the future of the Internet of Things. This technology It has a lot of potential for the Internet of Things. especially For data-intensive mobile applications where speed is critical. These include self-driving cars and emergency services.

5G networks can Advance near real-time data transmission. Moreover, they can maintain a stable connection with devices that move at very high speeds.

And while more advanced protocols generally require more power, 5G networks can Support cellular communication with low power consumption.

Low Power Wide Area Networks (LPWAN)

For the vast majority of IoT applications, manufacturers want to increase coverage while reducing energy consumption and costs. In recent years, they They have deployed new Low Power Wide Area Networks (LPWAN). Their goal is Meet the specialized needs of Internet of Things applications.

LPWANs enable IoT devices to Send or receive updates at specified intervals or in response to an external operator. This approach significantly reduces energy consumption.

There are two main types of LPWAN that IoT manufacturers need to be aware of for cellular connectivity.

NB-IoT (Narrow Bandwidth Internet of Things)

Narrowband IoT takes advantage of gaps in the radio frequency spectrum to Provide more efficient communication and avoid interference. Unused frequency bands are called ‘guardian bands’.

While cellular networks such as 4G LTE use broadband connections, Narrow-band communications isolate devices at “narrower” bands.

Narrowband IoT offers two main power saving features:

  • The Energy saving mode (PSM)
  • and the intermittent reception (DRX).

PSM causes the device to sleep when not in use, and DRX extends the active listening time of the signal. Therefore NB-IoT based devices It can have years of battery life.

LTE-M (Long Term Evolution of Machines)

LTE-M Allows IoT devices to connect to 4G networks. It provides them with more bandwidth and mobility than NB-IoT. In addition, it provides access to Voice over Long Term Evolution (VoLTE), a more advanced voice service. However, it is done at the expense of increased idle power consumption and more expensive modems.

Despite the increased power consumption, LTE-M can still take advantage of PSM and DRX to significantly extend the device’s battery life. LTE-M Uses less power than NB-IoT Because the higher bandwidth allows it to download data faster.

Is Cellular Internet of Things Right for Business?

For IoT makers, cellular connectivity offers many tremendous benefits. that they The solution could be to access the Internet of Things.

The advantage of using these mobile networks to connect devices is that“They are everywhere, just call them. This allows manufacturers to maximize coverage, maintain stable connections on the go, as well as increase the battery life of their IoT devices with LPWAN.

For manufacturers making IoT devices, cellular IoT isOne of the most reliable and accessible ways to enable internet connection.
