Smallest embedded cellular modem on the market

Skywire uses a standard XBEE form factor and 1xRTT CDMA operating mode to help developers minimize hardware and network costs, and a U.FL port to ensure antenna flexibility. The Skywire modem features the Telit CE910-DUAL and is available with bundled CDMA 1xRTT data plans from leading carriers. Compared to other embedded solutions on the market, Skywire is smaller — about 1/3 the size. Future versions will support GSM and LTE.  

The Skywire baseboard is an Arduino shield, allowing direct connection to an Arduino microcontroller. Skywire is available with a complete development kit that includes the cellular modem itself, baseboard, antenna, power supply, debug cables, and cellular service plan.

Skywire modems are available individually for $129 and in quantities of 1000 for $99. A complete development kit, including the modem, costs just $262.  They can be purchased through Symmetry Electronics at TechnologyPizza.com and SemiconductorStore.com.
