About wireless modules

Wireless modules are the component of an M2M device which produce, transmit and decode data over a cellular network. There are two basic wireless networks for which modules and M2M solutions are developed – GSM and CDMA. It can be differentiated by the cellular standard (GSM/UMTS/CDMA), the cellular data standards (GSM, UMTS, GPRS, EDGE, HSDPA), as well as by technologies (Java, GPS, SIM access profile). It is always used in a poor environment, so there’s always a high demand on the quality and reliability of wireless modules.

About M2M

M2M is an abbreviation for machine-to-machine, or technology that supports wired or wireless communication between devices. Wireless M2M comprises all wireless network technologies, even though the term is generally used in reference to systems connected to cellular networks.

Adoption of wireless M2M technology is still in a very early phase. As a share of total cellular connections, M2M generally accounts for 1–3 percent in developed markets and less than one percent in emerging markets. Some individual markets have higher adoption rates as a result of large-scale deployments such as GM OnStar in North America and smart metering solutions in Scandinavia. Automotive and fleet remains the largest vertical market and is expected to increase its share of the total market as more and more OEMs adopt telematics technology. Smart metering and other utility industry applications continue to grow, with initiatives triggered by the challenges facing the energy industry in all parts of the world. Fixed to mobile substitution drives the growth in the POS-terminal and security alarms segments. There are also high expectations for significant deployments of remote product and asset management solutions. (Incited from M2M Research Series 2008 by Berg Insight.)
