Machine to machine

<p>Machine to machine (M2M) is direct communication between devices using any <a href="/facts/Communications_channel/MtlxEShV">communications channel</a>, including <a href="/facts/Wired_communication/fPXbWAMU">wired</a> and <a href="/facts/Wireless/GfDoFwfo">wireless</a>. 
Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records (such as temperature, inventory level, etc.) to application <a href="/facts/Software/RP79lVSW">software</a> that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). 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 <a href="/facts/Personal_computer/koaYfNce">personal computer</a>.
</p><p>More recent machine to machine communication has changed into a system of networks that transmits data to personal appliances. The expansion of <a href="/facts/Internet_Protocol/Qq6VeEal">IP</a> networks around the world has made machine to machine communication quicker and easier while using less power. These networks also allow new business opportunities for consumers and suppliers.
