A combination satellite-cellular communication device emerged last week at the Cellular Telecommunications & Internet Association conference, where Elektrobit Corp. showcased reference designs for mobile handsets, PDAs and a general purpose "connectivity module."

The company claimed its reference designs will help laptops, automobiles, remote users with a USB port to have Internet connectivity regardless of location by automatically switching between cellular and satellite networks.

OEMs are currently examining the reference designs, according to Jani Lyrintzis, director of wireless solutions, Elektrobit. "Applications for the connectivity module include everything from laptops to service vehicles to remote meters that can be read wirelessly," he said.

Earlier this year, the company said TerreStar Corp. selected its mobile handset reference design for an integrated communications network TerreStar is designing in cooperation with AT&T. The TS-1 satellite, which will provide 2GHz mobile satellite-phone service, is currently being built by Space Systems/Loral Inc. The TS-1 will be launched in Q2 09.

Elektrobit also has shown its new module connected to a laptop computer via a USB port to provide VoIP, streaming video, Web browsing and e-mail access that can be switched between cellular and satellite connections.

The company also showed its combination quadband GSM and triband W-CDMA/HSPA-compatible PDA reference design, which requires no external antenna, along with its satellite-terrestrial mobile handset reference design. The design will be available to TerreStar subscribers for automatic switching between AT&T's cellular network and the satellite service after it is launched on the TS-1 satellite in 2009.
