Smartphones Plus Satellites

Globalstar and Iridium units break new ground.

Globalstar and Iridium base units allow smartphones and tablets to connect wirelessly to communication satellites.
Globalstar's Sat-Fi unit employs a hard-line power connection and measures about 6-by-6 inches.
Iridium's GO! is battery powered and small enough to fit into a shirt pocket. It weighs about 11 ounces and comes with a small antenna on the terminal.
