Current state of M2M (machine-to-machine) systems

Currently, wireless technologies are widely used, with which most devices already work. New systems are developed in such a way that as little as possible depends on human actions.

This review gives the general concept of the M2M system, what it consists of and where it is used, to identify the advantages and disadvantages of this system, as well as to identify its further development.

M2M - stands for machine-to-machine - literally means "from machine to machine", i.e. Data transfer is carried out directly between devices. For example, transmitting data from sensors to a processing server.
The M2M system includes peripheral nodes, communication equipment and software.
The peripheral nodes include all sorts of sensors that determine the parameters necessary for the client. For example, in fuel consumption control systems, these are liquid level sensors.

When the necessary information from the sensors is received, it is converted into digital signals and transmitted over the network. Signal transmission is provided by communication equipment. For data transmission, the GSM network, which is a developed infrastructure in almost all regions, has high reliability, low cost and the ability to transfer data to stationary or moving objects is currently used mainly as the medium. GPRS / EDGE, CSD / HSCSD and SMS are used as transport for data transmission in M2M solutions.

The software allows you to analyze the data received from the sensors, make any decisions and send commands to devices.

Diagram 1 shows the main areas of application of M2M systems, based on the analysis of MTS.

The main and main advantage of M2M is the possibility of the existence of a system that does not require human intervention. For example, systems that independently transmit data from indicators of household meters to housing and communal services, which simplifies the process of collecting and further paying utility bills.

Another promising example of the use of M2M systems is the project of the “Shop of the Future” - the so-called “smart” carts, as well as a common information system that controls the interaction of all elements of the store. Goods are marked with RFID tags, and readers are installed on carts that automatically transmit information about the composition and quantity of goods. Thus, the “smart” cart informs the cashier how many and what goods you have taken, and the cashier will automatically make settlements and accept payment from your card. On the scale of large retail chains, this will optimize logistics, significantly reduce staff costs, and shopping will become more convenient for customers and will take less time.

The disadvantages of the M2M system at the moment include the lack of generally accepted standards for machine-to-machine interaction at the application level. The lack of a single protocol makes direct interaction, for example, a refrigerator and a supermarket impossible.

Another disadvantage is the high cost of services of telecom operators, in the case of creating a wireless M2M system that transmits data over a GSM network. The complexity for implementing such an M2M also creates an incomplete network coverage area. The key problems for the Russian market are presented in Diagram 2.

Further miniaturization and cheapening of the components of the inter-machine interaction systems will reduce their cost and expand the intellectual capabilities of individual elements and M2M systems as a whole. At the same time, the use of cloud computing will reduce the requirements for the intelligence of M2M devices. As a result, the cost of the entire M2M systems will decrease.
