Machine to machine (M2M) refers to technologies that allow both wireless and wired systems to communicate with other devices of the same type M2M is a broad term as it does not pinpoint specific wireless or wired networking, information and communications technology. This broad term is particularly useful for business executives.
M2M can include the case of industrial instrumentation - comprising a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.) that is relayed through a network (wireless, wired or hybrid) to an application (software program) 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 personal computer.
However, modern M2M communication has expanded beyond a one-to-one connection and changed into a system of networks that transmits data to personal appliances.
The expansion of IP networks across the world has made it far easier for M2M communication to take place and has lessened the amount of power and time necessary for information to be communicated between machines. These networks also allow an array of new business opportunities and connections between consumers and producers in terms of the products being sold.
Considering M2M communications as a central point of future Internet, European Commission creates standardization mandate M/441. The mandate M/441, issued in 2009 to CEN, CENELEC and ETSI, in the field of measuring instruments for the development of an open architecture for utility meters ( water, gas, electricity, heat ), involving communication protocols enabling interoperability, is a major development in shaping the future European standards for smart metering and Advanced Metering Infrastructures.
The Winsonic WIDS ( Wifi IP Device Server) provides easy and reliable serial to Ethernet connectivity for the industrial automation market. The WIDS can be used to connect any serial device to IEEE 802.11 b/g network, and provide TCP server and TCP client modes to ensure the compatibility of network software. The WIDS provides the serial device server for Windows hosts to control serial devices located virtually anywhere through a TCP/IP Ethernet connection. The WIDS has the asynchronous serial port connection on one side, and a 10/100 Mbps Ethernet connection on the other side. Applications include industrial/factory automation, automatic warehouse control, and hospital/laboratory automation. The WIDS Windows driver installs a virtual COM on windows which maps the virtual COM port to the IP address of the WIDS device across the network, enabling the Windows applications to access remote serial devices over Ethernet.

The ZigBee 2012 specification has two implementation options or Feature Sets: ZigBee and ZigBee PRO.The ZigBee Feature Set is designed to support smaller networks with hundreds of devices in a single network.The ZigBee PRO Feature Set is the most popular choice of developers and the specification used for most Alliance developed standards. It maximizes all the capabilities of the ZigBee Feature Set, plus facilitates ease-of-use and advanced support for larger networks comprised of thousands of devices ZigBee PRO now offers an optional new and innovative feature.
The ZigBee specification enhances the IEEE 802.15.4 standard by adding network and security layers and an application framework. From this foundation, Alliance developed standards can be used to create a multi-vendor interoperable solutions. For custom application where interoperability is not required, manufacturers can create their own manufacturer specific standards.
