M2M vs IoT, what is the difference?

M2M and IoT are frequently mentioned in IT environments across all industries as key technology enablers in two relevant areas for innovation (Operations, where focus is to increase the operational efficiency, and Business Model, where focus is to innovate and establish new business models that generate additional value, creating differentiators for the company in the market). But when you ask what is M2M and what is IoT, even though you may find different descriptions of both topics, there is a tendence to confuse and mix both terms. I myself face this question very often, and I would like to provide here my personal opinion, also for readers not familiar with these topics. This is not necessarily right or wrong, but after several years in this area, I’m convinced  that this is a good way to define and differentiate M2M and IoT and hope it helps some people to build an opinion. 

First, it is necessary to clarify what the acronyms M2M and IoT stand for, and what is behind them:

  • M2M stands for Machine-to-Machine. It is important to note, that the term is not used to refer to the communication between any two devices (for example, a communication established between a mobile phone and a tablet through bluetooth). Even though semantically it could be said that this is machine to machine communication, the term in reality refers to the remote communication between a device and a central system that monitors and controls the device. One of the key characteristics, also, is that this communication takes place to a big extent without human intervention (needed for the previous bluetooth connection).

  • Turning to IoT, the acronym stands for Internet of Things, referring to a network of interconnected things. Intuitively, it could be be said that M2M is a one-to-one communication while IoT builds a network enabling a complexer communication environment. In the end, Internet was adopted as a term to refer to the network of networks. While in M2M we talk about a given type of devices remotely monitored and controlled by a central system, IoT opens a new world of dimensions, with different types of devices and integration of other sources of information interacting one with another through different technologies and networks.

Before diving deeper, it is good to clarify something about the term M2M. M2M is largely used by Mobile Network Operators to refer to wireless communication capabilities based on SIM Cards and the control of those communication capabilities, but M2M is not necessarily limited to that. In fact any connectivity media that enables the remote communication between machines can be used to enable M2M communication. Apart from already available and well established standardized technologies for long distance communication (mobile wireless communication, fixed line or wired communication, satellite…), there are many potential topologies where other technologies can play a role in M2M or IoT applications (Bluetooth, NFC, RFID, WiFi, …). There are also newcomers in the technology world to enable long distance communication for devices requiring to send & receive small pieces of information and have a long battery life. These are the so called Low Power Wide Area (LPWA) Networks, with technologies like SigFox, Neul, LoRa, … Although standardization will play a key role, we will most probably see a long period where different technologies will live together. One of the challenges that we will face in this environment will be ensuring security in this multi-dimensional environment, also due to the lack of maturity of new arising technologies. 

That has a sound business credit history, outstanding after-sales service and modern producing facilities, we have earned an superb popularity amid our buyers across the planet for Industrial Logger PLC WiFi ADSL 4G Modem Router Qca9531 Openwrt. We are looking forward to forming successful business relationships with you in near future.
