Technology advancement is occurring at a rapid pace and so does technology innovation. “M2M” and “IOT” are 2 innovation terms which are common discussion points of the technical innovation community.
Notable is that M2M may be called the predecessor of IoT. Let’s understand the terms & difference in M2M and IOT in more detail.
M2M or Machine to Machine –
M2M concept refers to two or more machines can communicate with each other and carry out certain functions without human intervention. Some degree of intelligence can be observed in the M2M model. Some of key applications which leverage M2M technology to provide services are –
- Warehouse Management Systems (WMS)
- Supply Chain Management (SCM)
- Harvesting energy like oil and gas
- Customer billing like smart meters
- Traffic control
- Remote monitoring
IoT or Internet of Things –
IoT refers is an ecosystem of connected devices (via the Internet) where the devices have the ability to collect and transfer data over a network automatically without human intervention. IoT helps objects to interact with internal and/or external environment which in turn control the decision making. Some of applications and services of IOT Technology are –
- Smart Home
- Connected cars
- Agriculture and Retail
- Smart cities
- Poultry and Farming
M2M vs IoT
In M2M vs IoT, M2M solutions contain a linear communication channel between various machines that enables them to form a work cycle. It’s more of a cause and effect relation where one action triggers the other machinery into activity. Conversely, in case of IoT, multiple devices communicate with each other through sensors and digital connectivity.
While M2M (machine to machine) is commonly associated with isolated solutions like a solution of Wi-Fi thermostats, a vehicle location system or home automation, IoT (Internet of Things) works by stretching its boundaries and integrating multiple disparate systems into outputs beneficial for Business goals.
Another key differentiator is that M2M’s key focus is on direct point-to-point connectivity across mobile networks or fixed-line while IoT communication involves IP networks and will usually employ cloud or middleware platforms
When we consider the scalability in M2M vs IoT, clearly IOT wins the race since it works on Cloud-based architecture and as we know Cloud can expand substantially.
Also, IoT makes use of Open APIs for communication across distinct systems while M2M mostly has limited or no open APIs.
