What is M2M ? – A History
M2M is an acronym with many possible meanings from mobile-to-mobile and machine-to-mobile to man-to-machine, machine-to-man and machine-to-machine. From our perspective, M2M is an abbreviation for machine-to-machine communication.
M2M communication is, as the name suggests, an exchange of data or communication that takes place between two machines without human interface or interaction. M2M is in a way similar to the Internet of Things (IoT) in that both offer a similar promise, that is, to fundamentally change the way the world operates. As in the case of IoT, M2M allows sensors to communicate and operate on their own, thus opening up possibilities to monitor themselves and respond appropriately to the changes in the environment. They are different in that IoT typically refers to wireless communication while M2M can refer to both wired and wireless communication between any two machines.
The most well-known example of M2M communication is telematics which involves data transfer for commercial purposes. Pioneers of telemetrics first made use of telephone lines, and later, radio waves to transmit performance metrics that were gathered from monitoring instruments from remote regions.
Internal Work Process Improvements
Improvements in wireless technology and the Internet have ensured an expansion of the role of the technology from engineering and manufacturing to the cellular arena. Wireless M2M has been dominating the 2G cellular network ever since it was launched in the mid-2000s and several companies began offering M2M data plans. However, M2M is not entirely a cellular-only area – it finds use in products like home heating units, Internet-connected appliances and healthcare services among others. Products based on M2M technology are often marketed to end users as “smart” products.
Currently, most M2M systems are either built to be task-specific or device-specific. Going forward, as the use of M2M technology expands, vendors would need to draft and agree upon some common standards for machine-to-machine communications.
How M2M Works?
M2M technology includes the use of wireless modules or sensors, a Wi-Fi or cellular communications link and autonomic computing software program. The wireless or sensors are embedded in a device/s and they enable the transmission of data contained within these devises autonomously or as requested by other applications. A communication link connects the device/s to another device or computer server. A software application or program is then used to analyse the data and make decisions.
According to Forbes, M2M technology is one of the fastest growing technologies in the world given that it can connect millions of devices in a single network. Virtually everything that houses a sensor can be connected to a wireless network and then to a machine with software for data analysis and interpretation, and consequently, further action.
M2M is similar to LAN and WAN networks but is used to connect machines to allow them to communicate. The technology allows for humans or a control unit to monitor and assess the communication across the entire network and issue appropriate instructions to member devices, as necessary.
M2M Application – Manufacture
Technology finds extensive use in the manufacturing industry as it enables companies to cut costs, automate their processes and execute them efficiently. In the manufacturing arena, M2M can be used to automate maintenance of equipment. As a case point, maintenance personnel can be alerted via SMS when an equipment needs servicing. This allows them to address issues as soon as they arise. To go further, the M2M networks can also be programed to automate the placing of orders for replacement parts.
Healthcare device management
Hospitals can put M2M technology to use to provide the highest level of care to their patients. For instance, when a person’s vital signs fall below normal, an M2M-capable device can automatically administer oxygen and additional care till the time a healthcare professional arrives at the bedside to take over. Time is precious during an emergency and immediate response can help to save a life. Then again, the technology allows patients to be monitored in their homes rather than being in the hospitals. In this context, M2M-enabled devices can be used to track a patient’s movements and alert a healthcare professional in case his vitals undergo a change or he suffers a mishap.
M2M Application – Limitations
Organisations across the globe are considering or implementing M2M solutions to improve production and performance, and cut costs. Hertz uses the technology to track rental cars and even unlock them if a renter has left the keys inside. Businesses such as manufacturers of high-value items, temperature-sensitive medications, trucks and containers are increasingly turning to M2M. The possibilities of use are limitless – however, there is a catch – a number of factors can stall the use of the technology. Security is the most critical of these factors. Businesses still rely on external partners to deliver mission-critical services and in such a situation, data and personal privacy can be threatened. Then there are other issues such as reliability, availability, scalability, interoperability and cost that need to be addressed.
M2M is witnessing an impressive growth in the market and experts predict that low power, wide-area network (LPWAN) connections will grow from 11 million in 2014 to 5 billion, amounting to $7.1 trillion in 2020. Many major cellular operators such as Verizon and AT&T are already rolling out their M2M platforms to take advantage of this major industry growth spurt. M2M offers a great opportunity for companies to automate their solutions and streamline their processes in almost all industries. Going forward, in the next five years, a huge influx of companies innovating in this arena will be witnessed.
