Compute Module 4 cutting edge in Industrial IoT

Few months ago IoT Industrial Devices predicted a possible release date for Compute Module 4 in Standard and Lite version:

Upcoming Raspberry Pi Compute Module 4 possible release date
Raspberry Pi release timeline with probable Compute Module 4 release date

First Rasbperry Pi 1B model had it’s analogy in industrial Compute Module 1 after almost 2 years from it’s premiere. Compute Module 2 was probably omitted because the change from RPi1 to RPI2 mainly involved a minor change of the processor (Cortex-A7 900MHz), which was almost immediately replaced with Cortex-A53 1.2GHz in Raspberry Pi 3.

The premiere of Compute Module 3 occured a year after RPI 3 announcement, providing a significant boost of industrial market solutions. Since Raspberry Pi 4 was a great success in 2019, we might see it’s equivalent in industrial series of Raspberry Pi – Compute Module 4. A possible release date of Raspberry Pi’s Compute Module 4 is mid-2020.

Raspberry Pi is gaining recognition in Industry

Almost a year ago, in the beginning of 2019, Raspberry Pi Foundation presented Raspberry Pi Compute Module 3+, a successor to previous CM3 version of development board, aimed at businesses and industrial users. The Compute Module uses a standard DDR2 SODIMM (small outline dual in-line memory module) form factor. GPIO and other I/O functions are routed through the 200 pins on the board.

Only a few months later, in June 2019, came big premiere of Raspberry Pi 4 Model B, the long-awaited successor of customer RPi3+. With new processor, larger RAM options and many input/output changes, became new standard in small, embedded PC world.

Official Raspberry Pi’s information about upcoming Compute Module 4

In recent interview with Eben Upton, the CEO of Raspberry Pi Trading, we finally had Raspberry Pi Compute Module 4 release confirmation, probably in 2021. He shared some details about the upcoming CM4 features, such as single-lane NVMe support.

The Raspberry Pi Compute Module, CM4, we will support NVMe to some degree on that,  because of course, it [Raspberry Pi 4] has a PCI Express channel. (…) We have a single lane Gen 2 which is used to supply USB 3.0 on the Raspberry Pi [4].

  • Current flash memory (eMMC) options: 8GB / 16GB / 32GB from CM3+ will probably stay the same,
  • weight and factor will stay the same, to provide a possibility to upgrade current IoT applications of CM3 and CM3+

With much higher performance, the new Raspberry Pi Compute Module 4 will, for sure, support Gigabit Ethernet, USB 3.0 expansions with PCIe/NVMe single lane.

Advantages of Industrial IoT in modern manufacturing and smart environments

Industrial Internet of Things (Industrial IoT or just IIoT for short) uses Internet of Things technology to improve production and industrial processes. These processes increasingly require connected devices to perform their tasks effectively.

Data generated over the Internet of Things is growing exponentially faster than the traditional cloud environment where data is stored, so just the amount of data can justify the acceleration. In addition, in the cloud as the destination, problems related to data transfer (delay and bandwidth) occur, so travel speed is the main issue. This edge is necessary as a solution to the inefficiency of IIoT to Cloud architecture.

IIoT market predictions

Industrial IoT devices and edge computing have grown at impressive rates. Accenture predicts the IIoT market will reach $500 billion by 2020; and IIoT already generates 400 zetabytes a year. Gartner estimates that IoT currently generates about 10% of enterprise data; by 2022, Gartner has predicted this will increase to 50%.

According to IDC, IT’s annual investment on edge infrastructure will hit 18% of total IoT spending; and per last year’s Forrester Analytics Global Business Technographics Mobility Survey, 27% of global telecom decision-makers say their companies will either implement or expand edge computing this year.

Perimeter (edge) computing architectures bring computing processing closer to the users and devices that need it, rather than centrally processing it in a local data center or public cloud. This edge is important for industrial and production processes that use large amounts of data that require fast response times and tight security.

Fast data processing of Industrial IoT devices

When industrial IoT devices and edge processing work together, digital information becomes more powerful. Especially in contexts where you need to collect data in a traditional edge context, such as a smart meter, a parking meter or a connected trash can in a street apartment. The installation of sensors with internet access in metropolitan garbage containers is becoming increasingly common for smart urban engineers. You can then remotely monitor the container using the sensor. When it is full, the city sanitation service receives a notification and can register an order and empty the container.

By introducing AI (artificial intelligence) into the device itself, edge computing can also make more context-sensitive, quick decisions at the edge. Data gathered from the sensors can be transferred to the cloud at any time after local work has been completed, contributing to a more global AI process, or archived. With the combination of industrial IoT devices and advanced technology, high quality analysis and small footprint will become the AI standard in 2020.

Industrial IoT use of ESP32 chip in eModGATE

Latest innovations used in industrial solutions

One of many uses of IoT can be edge devices, dedicated to data management, process control (e.g. with MQTT protocol) and monitoring. Latest ESP32-based eModGATE controller from TECHBASE company is a series utilizing MicroPython environment to provide data management solutions for end-points applications. The eModGATE has built-in Wi-Fi/BT modem and can be equipped with additional NarrowBand-IoT, LoRa, ZigBee, etc.

For example eModGATE eqipped with wireless NB-IoT modem are perfect for industrial automation solutions, e.g. data logging, metering, telemetrics, remote monitoring, security and data management through all Industrial IoT applications.

Upcoming Wi-Fi 6 802.11ax and Wi-Fi 7 802.11be forecast for industrial IoT

The new Wi-Fi 6 standard, also known as 802.11ax, is the latest stage in the development of this technology. Based on the benefits of the 802.11ac standard, this standard also provides performance, flexibility and scalability, which in new and existing networks means an increase in speed and bandwidth for new generation applications.

Wi-Fi 6 is now coming to telephones, laptops and network equipment. But engineers are already looking at: Wi-Fi 7. With a high speed of 30 gigabits per second, the new generation of Wi-Fi will offer better video streaming, longer distances and reduced problems with data traffic.

What is Wi-Fi 6?

The Wi-Fi 6 standard enables enterprises and service providers to support new and emerging applications within the same wireless LAN (WLAN) infrastructure while ensuring higher standards of support for older applications. This scenario prepares the ground for new business models and increased use of Wi-Fi.

Upcoming Wi-Fi 6 and Wi-Fi 7 forecast for industrial IoT
Source: TP-Link

This is exactly the same standard as 802.11ax. The Wi-Fi Alliance has launched a campaign to give the IEEE 802.11ax standard the name „Wi-Fi 6”. This name suggests that this standard is a 6th generation Wi-Fi network. The justification for this idea was to simplify the marketing message of the 802.11ax standard in order to gain an image advantage over the standards of the Third Generation Partnership Project (3GPP) used in cellular network technology (e.g. 5G).

Wi-Fi 6 – 802.11ax features

The Wi-Fi 6 network will be based on the success of the 802.11 ac standard. This standard will allow access points to support more clients in dense environments and provide higher standards of use for typical wireless LANs. It will also provide more predictable utility properties for the needs of advanced applications, e.g. for 4K or 8K video playback, high density and high resolution collaboration, fully wireless offices and the Internet of Things (IoT). The Wi-Fi 6 standard will allow Wi-Fi networks to face the challenges of the future accompanying the development of wireless networks.

As with any new product in the area of Wi-Fi technology, the Wi-Fi 6 network is backward compatible with older technologies on which it is based and which makes it more efficient.

Expectations about Wi-Fi 7 standard

During a speech during the August Wi-Fi Qualcomm Day and subsequent interviews, V.K. Jones, vice president of technology, shared details about the operation of Wi-Fi 7. He expects a three-step improvement over today’s Wi-Fi 6, called 802.11ax in the world of technology.

The first improvement expected will increase Wi-Fi 6 bandwidth and use new radio waves that will allow the governments of the United States and Europe to start wireless transmission soon next year. Secondly, the Wi-Fi 6 update in 2022 should improve speed, especially for those who transfer data such as videos from phones and computers. The third, and perhaps the most interesting, is the Wi-Fi update collection expected in 2024, known only under the technical name 802.11be.

Is LoRa a 'must be' for Industrial IoT?

As the remote application market is growing rapidly, technology also needs to progress, ensuring greater range and transmission speed while reducing energy consumption. Technological progress makes it possible to create innovative standards for new, sophisticated applications that facilitate our life and work. One of wireless connection choices can be LoRa technogoly.

What exactly is LoRaWAN?

LoRa (Long Range Radio) technology with low data throughput allows IoT and M2M applications to communicate wirelessly over 15 kilometers, with a battery life of more than 10 years. LoRa allows you to connect millions of wireless nodes with compatible gateways and has several key advantages over other wireless solutions. For example, it uses spectrum spreading modulation with the ability to demodulate a signal 20 dB below the noise level.

LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe) and 915 MHz (Australia and North America). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption.[4] The technology is presented in two parts: LoRa, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

Source: https://en.wikipedia.org/wiki/LoRa

Compared to 3G and 4G cellular networks, LoRa technology is also better scalable and more cost-effective for embedded applications. It has a much greater range than other popular wireless protocols, which allows devices to operate without amplifiers, reducing the total cost of the application.

Thanks to scalability, reliable communication, mobility and ability to work in difficult external conditions, the LoRa module is perfectly suited for use in a wide range of wireless monitoring and control applications that do not require high transmission speeds. Examples of applications may include smart city (street lighting sensors, motion sensors), energy (intelligent measurement of electricity / water / gas consumption) and industrial / commercial / home applications, among others HVAC, intelligent devices, security systems and lighting.

Use of LoRa in industrial automation

Use of wireless connection makes life and work easier for us every day – from radio stations and GSM to Wi-Fi wireless networks, Zigbee, short-range Bluetooth connectivity and LoRa. With the spread of internet access, the possibility of using wireless connectivity for a new type of service and application has opened. Terminology such as M2M (Machine to Machine) – remote communication between devices and IoT – a network of applications and devices communicating with the Internet have been created.

Device equipped with LoRa module is delivered with a LoRaWAN protocol stack, so it can be easily connected to the existing, fast-growing LoRa Alliance infrastructure – both in privately managed local area networks (LAN) and public telecommunications networks to create wide area low power WAN (LPWAN) on a national scale. LoRaWAN stack integration also allows connection to any microcontroller, such as ModBerry industrial device from TECHBASE.

Power Management HAT with RTC for Raspberry Pi

If you’re looking for a useful tool for long-lasting Raspberry Pi, such as longer battery life or automatic power on / off, this HAT power management is the perfect choice.

This HAT can significantly increase battery life by automatically starting the device for a certain time and automatically switching it off at another time. It can be configured to monitor the Raspberry Pi voltage / current status in real time and turn off the Pi according to the operating status. In addition, the kit includes a convenient power switch for easy on / off (soft shutdown of Pi by software), preventing data loss due to power disconnection.

The NB-IoT is becoming a standard in wireless communication of IoT devices, for standalone solutions and complex installations with thousands of units, coordinated with gateways. Will NarrowBand-IoT replace other wireless technologies in industrial automation?

What exactly is NarrowBand?

NarrowBand-IoT (NB-IoT) is a radio technology in the field of LPWAN (Low Power Wide Area Network) dedicated for IoT devices, operating on the licensed frequency band used by telecommunications operators.

The biggest advantages of NB-IoT include:

  • long battery life (up to 10 years),
  • efficiency in the amount of data transferred,
  • intra-building penetration,
  • the ability to connect even tens of thousands of devices in one system,
  • a global standard,
  • a high level of security and low cost

You can build mass solutions and those that until now were considered unprofitable. NB-IoT technology works in the licensed band, so there is no risk of interference and blocking communication by competing networks.

The service life of devices powered by two AA batteries is up to 10 years. However, the devices themselves are constructed in such a way that they can work for many years without the need for technical supervision and recharging the battery.

NB-IoT used in industrial solutions

One of many uses of NarrowBand-IoT wireless modems can be communication of edge devices, dedicated to data management, process control (e.g. with MQTT protocol) and monitoring. Latest ESP32-based eModGATE controller from TECHBASE company is a series utilizing MicroPython environment to provide data management solutions for end-points applications. The eModGATE has built-in Wi-Fi/BT modem and can be equipped with additional NarrowBand-IoT modems

eModGATE eqipped with wireless NB-IoT modem are perfect for industrial automation solutions, e.g. data logging, metering, telemetrics, remote monitoring, security and data management through all Industrial IoT applications.
