First, the cost of M2M components has dropped considerably over the last two years. Although Juniper does not focus much on technology here, it does mention the role of cellular radios, as well as WiFi, ZigBee, Bluetooth, and NFC, listed here in order of descending wireless reach.
Of course, embedded boards are often required to control or communicate with such devices, so the M2M ecosystem appears to be fairly broad. As for cellular technology, Juniper notes that M2M devices do not typically require 3G bandwidth.

As noted in a 2007 ABI Research report on M2M, the reason operators have not shown greater interest before is the lack of profitability compared to human-driven voice and data services. "Since ARPU for M2M and embedded devices is lower than for standard mobile services," says Juniper, mobile operators are now realizing that large scale is essential to a profitable M2M business./p>
According to Juniper, new and expected restrictions on carbon footprint and energy use are increasing the demand for smart meters, which are designed to wirelessly communicate with central utility servers. In many cases, these devices also communicate with a new class of local, GUI-enabled monitoring and control devices, such as SilverPac's SilverStat 7 (pictured at right).
Power meters are expected to be the clear leader in driving the M2M business in the coming years, says Juniper. "The most widespread category will be connections related to smart metering, driven partly by government initiatives to reduce carbon emissions," said Anthony Cox, senior analyst at Juniper Research, in a statement.
After smart meters, vehicular telematics and "connected buildings" will track at a distant second at about the same fast-growing levels over the next five years, according to the study. The connected building market includes wireless sensors that track everything from temperature to security.
A late bloomer will be healthcare monitoring devices, which will begin to reach the commercial roll-out stage in 2012, says the research firm. Healthcare should be particularly lucrative, however, for providing add-on services, which is key for mobile operators' plans on making money off of M2M, notes Juniper. Services will also be the most costly component of M2M, representing over 70 percent of total costs.

Availability
The 97-page Juniper Research report, "Embedded Mobile & M2M Strategies: Healthcare, Telematics, Metering & Connected Buildings 2009-2014," is available now at prices starting at 1750 Pounds (about $2,860 U.S.). The report is said to include six-year forecasts and analysis for key mobile M2M parameters and attributable service revenues.
