Machine-to-Machine (M2M) and Machine-Type Communications are among the Connected Devices that will be a part of the Internet of Things (IoT). Connected Devices also includes personal computing devices such as PCs, mobile handsets and tablets. They may be as simply defined as solutions that bundle together devices, network services, and applications to create, extract, act upon, or consume information. Machina Research defines Connected Devices as all devices used for transmitting and receiving packet data telecommunications via any wide-area or local area network. Connected Devices could be divided into three groups:
M2M and the Internet of Things: A guide. ZDNet, January 10, 2013
Yankee Group’s Global Cellular M2M Forecast forecasts 480 million cellular-enabled M2M connections by 2017 due to the technologies:
The 3GPP family of technologies offers M2M solution providers the most flexible range of high and low bandwidth network options that range from 2G GSM-General Packet Radio Service (GPRS) to 3G High Speed Packet Access (HSPA) to 4G Long Term Evolution (LTE). However, because the product life of M2M devices is often in excess of ten years, and due to the rapid expansion of LTE coverage and its unprecedented high adoption rate worldwide, LTE modules are making strong inroads into M2M devices that require built-in security along with robust traffic management capabilities. Additionally LTE is significantly more spectrally efficient than 2G or 3G, and thus transporting data over LTE can be done at a much lower cost per bit. Some analysis indicates that LTE is two to three times more efficient than 3G; and 20 times more efficient than 2G. This translates into cost efficiencies over the lifetime of the module. One analyst has estimated that data costing a dollar to send over a 2G network can be sent over an LTE network for only 5 cents. Due to this economic incentive, many operators worldwide are re-farming their 2G and 3G spectrum and moving to LTE.
LTE chipsets are the foundation of highly optimized IoT and M2M devices with the features and functionality required to build robust long-life devices for numerous applications at a low cost. Features may include a small footprint, ultra-low power consumption, a mature and software-customizable software suite, and ‘drop-in’ simplicity for ease-of-integration. Many operators offer multi-mode HSPA-LTE devices to provide service continuity for true international mobility and service.
