Iridium Communications Inc. (Nasdaq:IRDM) announces that it has signed agreements with five new value-added partners to market Iridium-based data solutions for the mobile machine-to-machine (M2M) sector. These new partnerships, including the company’s first-ever consumer Iridium short-burst data (SBD) relationships, open up numerous customer opportunities.

“Alliances with well-established, world-class partners will spearhead our growth, and solidify our market leadership, in transportation, industrial, security, consumer and other higher-volume sectors,” said Greg Ewert, executive vice president, global distribution channels, Iridium. “The companies will leverage Iridium’s global, low-latency, two-way satellite data links and our next-generation Iridium 9602 SBD transceiver to create innovative, low-cost M2M solutions for broad-based government, commercial and consumer markets.”

The new partners are:

* ACR Electronics (www.acrelectronics.com), a subsidiary of Cobham plc, manufactures safety and survival products for marine, aviation and military markets.

“With these partnerships, Iridium is aligning itself with best-of-breed companies that are the clear market leaders in remote tracking, monitoring and control applications,” said Patrick Shay, vice president of data services, Iridium. “These are industry-leading M2M companies with the expertise, customer relationships and market clout that will further accelerate market growth for Iridium’s satellite data business.”

Tim Farrar, president of TMF Associates, commented, “Iridium’s new low-cost SBD transceiver and partnerships with established world-class players in the mobile data industry will further accelerate Iridium’s already rapid growth in the M2M sector. We believe the company is well positioned to capture a significant share of the market for low-data-rate mobile satellite devices, which is projected to grow by more than 20 percent annually to more than 3.4 million units in service by the end of 2014.”
