MACHINE TO MACHINE (M2M)

M2M refers to technologies that allow both wireless and wired systems to communicate with other devices of the same ability. M2M uses a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application software that translates the captured event into meaningful information. Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a PC.

Wireless media can be GSM, satellite and RF. Devices need different interfaces that are used for communicating to sensors or other electronic devices. RS232, RS485, Ethernet, USB, BT, Canbus are primarily used in the M2M world.

BIOS can replace all of interfaces and wireless media in her designs.

M2M can serve to improve production and efficiency in various areas, including machinery that works on building cars and on letting the developers of products know when certain products need to be taken in for maintenance and for what.

A second application is to use M2M technology to monitor systems, such as utility meters. This would allow the owner of the meter to know if certain elements have been tampered with, which serves as a quality method to stop fraud.

A third application is to use M2M networks to update digital billboards. This allows advertisers to display different messages based on time of day or day-of-week, and allows quick global changes for messages, such as pricing changes for gasoline.
A fourth application is to use M2M networks to observe vending machines, elevators and generators.

Telematics and in-vehicle entertainment is an area of M2M solutions that includes the ability for the owner to monitor and control vehicle conditions, locate fuel stations, pre-heat or cool the car.
