M2M stands for Machine-Machine, which means the exchange of data between a remote mobile or fixed machine and the back-end IT infrastructure. The automatic transmission of data can be bi-directional: upwards are the gathering of information from sensors in the field, and downwards are the broadcasting of instructions, updating of configuration or monitoring of equipment from a centralized control center.
M2M was first used in the telemetry field to enable remote measurements and report performance data to system operators. In the past, only large financial organizations were able to use telemetry systems and use dedicated data networks. Today's M2M allows more people to implement remote data acquisition and control. Improvements in technology, miniaturization, and technical performance, as well as the development of communication networks, coupled with the accelerated promotion of IT systems in the entire society, have enabled organizations in all industrial fields to use wireless M2M today.
A typical M2M system has these key components: a set of devices that can automatically transmit data collected through various sensors, a communication link that connects these devices to a computer server, and a storage device for A database of data, and a software interface for analyzing, reporting, and executing data.
M2M seems to be boring - those monitors will periodically wake up, send some sporadic data and then continue to sleep. According to Frost & Sullivan, monthly wireless carriers’ revenue from these applications may be only a few dollars, only 1/10 of the voice service revenue, but the number of M2M devices is 10 times the number of voice users.
According to analyst firm Berg Insight, the number of devices connected to cellular networks in North America by the end of 2011 will reach 66 million units, up from 9 million in 2006 using cellular and satellite equipment. Harbor Research said that today there are 110 million M2M devices in use worldwide, communicating with each other in a "device Internet."
Analysts and industry insiders said that M2M has reached a turning point and will turn to faster development. Sam Lucero, ABI Research analyst with years of research experience in the cellular M2M industry, said that in the next few years, the M2M industry will grow at an annual rate of 25%, and its service revenue will grow from 2 billion US dollars last year to 2012. The annual 8 billion US dollars.
Wireless M2M in Factory Environment
In today's M2M technology, a new type of revenue that is growing rapidly is revenue from real-time maintenance, management, and industrial site control. Companies in many manufacturing industries are using this technology to permanently monitor overseas factory assembly lines and equipment with limited manpower and increase service productivity.
For example, manufacturers of construction machinery and warehouse logistics systems, as well as manufacturers of printers and copiers, have adopted M2M. Vendors who temporarily lease equipment to customers need to monitor their equipment on a regular basis. For example, machinery manufacturing companies that rent equipment or ship equipment to customers face the pressure to meet changing market demands.
What customers need is the best service and product availability and expects 24/7 service. New payment methods, such as pay-per-view fees, are putting increasing pressure on machinery manufacturers. Safe, accurate, and real-time data are the key factors for success in this business area. Such payment methods will inevitably be accepted by end users such as construction companies or construction companies. They will not need to spend money to purchase these machines, but they can rent or pay for it, and they can also get a worry-free repair service from the rental party.
In the industrial field, to control the low cost and operate the machine at the best efficiency, it is necessary to obtain the correct information before the failure occurs. Service personnel must be informed in advance about the relevant maintenance requirements. Providing the correct materials for the machine facilitates logistics cost control and environmental protection. The further penetration of electronic systems in the once purely mechanical industrial sector paves the way for various M2M services to enter the field.
The Aberdeen Group listed several advantages of M2M in its 2007 annual report "Impact of Smart Devices on Consumers and Business": higher customer stability, longer machine uptime, increased service revenue and profitability, and corresponding services The increase in speed, as well as the reduction in the number of maintenance and distribution technicians.
More and more industries are now applying mobile M2M to their businesses, including tracking raw materials and manufactured goods in global transportation routes, managing on-site mobile resources, and monitoring sensitive equipment or production environments.
