This year we’ve attended several technical meetings and conferences in the design, engineering, and manufacturing realms and have heard one concept/phrase repeated much more than anything else – Internet of Things (IoT). That said, we consider IoT to be the most significant technology of the year for 2014.
Simply, IoT is a newer implementation and outgrowth of an older technology known as Machine-to-Machine (M2M).
The Internet of Things (IoT) refers to uniquely identifiable objects and their virtual representations in an Internet-like structure. The term Internet of Things was proposed by Kevin Ashton in 1999, although the concept had been discussed since 1991.
Radio-frequency identification (RFID) was seen as a prerequisite for the Internet of Things in the early days. The initial thought was, if all objects and people in daily life were equipped with identifiers, they could be managed and inventoried by computers.
Today, the term IoT is used to denote advanced connectivity of devices, systems, and services that goes beyond machine-to-machine (M2M) communications and covers a variety of protocols, domains, and applications. Both of the technologies are expected to enable billions of new devices in the near future (I’ve seen forecasts of 20-100 billion connected devices by 2018 or 2020).

In most M2M and IoT scenarios, the device being monitored and/or controlled contains an integrated sensor and wireless transceiver connected through a cellular, WiFi, or other wireless link to the Internet. Keep in mind that all devices are assigned an Internet Protocol (IP) address for unique identification and role purposes. The Internet connection communicates with a remote server that contains the application software. The monitoring device then makes an Internet connection to the same server to complete the service request loop.
Data from the communication is then captured, displayed, stored, and control commands are issued as a result of it.

In mechanical design and engineering, while many of the hardware and software vendors have expressed interest in IoT, PTC has really embraced it and positioned it as a major part of their overall strategy going forward.
