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 wireless 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. In recent years, SMS has become an increasingly important transmission mechanism for M2M communication, with the ubiquity of GSM and the relatively low cost of SMS being cited as advantages. Concerns have been raised over the reliability of SMS as an M2M channel, however the rise of direct Signaling System 7 (SS7) connected SMS gateways, which can offer increased reliability and the ability to confirm delivery, have allayed many of these fears.
