M2M explained in detail for engineers

In this era of IoT understanding M2M is also very important. M2M as name suggest is Machine 2 (to) Machine. What?: Communication. Communication between 2 or more machines is M2M.

Machine to machine refers to direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the data it records (such as temperature, inventory level, etc.).

Application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer.

We’ve heard a lot of talk about the Internet of Things (IoT) and all its benefits for subscribers and service providers alike, but there has been an increasing level of confusion going around the communication service provider industry between IoT and machine-to-machine (M2M) communication. This confusion stems from misconceptions when referring to both the similarities and differences between the two distinct concepts.

Here are few key difference between M2M and IoT:

As businesses have realized the value of M2M, it has taken on a new name: the Internet of Things (IoT). Both have similar promises: to fundamentally change the way the world operates. Just like IoT, it allows virtually any sensor to communicate, which opens up the possibility of systems monitoring themselves and automatically responding to changes in the environment, with a much reduced need for human involvement. They are almost synonymous—the exception is IoT (the newer term) typically refers to wireless communications, whereas M2M can refer to any two machines—wired or wireless—communicating with one another.

it is among the fastest-growing types of connected device technologies in the market right now, largely because this technologies can connect millions of devices within a single network. The range of connected devices includes anything from vending machines to medical equipment to vehicles to buildings. Virtually anything that houses sensor or control technology can be connected to some sort of wireless network.

M2M Applications

  1. Manufacturing
  2. Home Appliances
  3. Health care
  4. Smart utility
  5. and more… 

There is a technology of Machine to machine about which I want to  talk about.

Machine to Machine SIM

It refers to the technology that enables devices and sensors or “things” to communicate with each other – and with other internet-enabled devices and systems.
Even though it refers to “non-human” communication, devices still should have interchangeable protocol which is used for receiving and sending data. Connectivity is achieved by either inserting or embedding a Machine-to-Machine SIM in the device that is later configured with the home server where all the usage data is collected and can be analyzed for company’s beneficial purposes.

Why M2M sim instead of normal sim?

In order to connect our machines to the internet we can’t always rely on a fixed internet connection. In many circumstances a cellular connection would be far more beneficial. That being said, a standard mobile SIM card doesn’t offer you the same critical features and functionalities that an M2M SIM does.

An M2M SIM card is primarily used for sending and receiving data. Not for voice and texts (although some providers are able to attach SMS bundles to your solution). These SIMs are able to provide you with GPRS, 2G, 3G and also 4G connectivity, depending on your chosen tariff.

Machine to Machine SIM cards also allow you aggregate data across your SIM estate. This gives you the flexibility to share data across all of your connected devices. If one of your devices is overusing data and another is under-using, they’ll both take data from the same pot. Therefore you can rest knowing that overspending is far less likely.

Final Points

Many big cell operators, like AT&T and Verizon, see the potential in IoT and are rolling out their own M2M platforms. Whereas Intel, PTC, and Wipro are all marketing heavily in M2M; and working to take advantage of this major industry growth spurt. But there is still a great opportunity for new technology companies to engage in highly automated solutions; to help streamline processes in nearly any type of industry;. We’re certain we’ll see a huge influx of companies who begin; to innovate in this area in the next five years.

Currently, M2M does not have a standardized connected device platform and many M2M systems are built to be task- or device-specific. It is expected that as M2M becomes more pervasive, vendors will need to agree upon standards for device-to-device communications.
