Qualcomm has resurrected its mobile healthcare service less than a year after pulling the plug on the joint venture.

Lifecomm will be reborn as a joint venture between Hughes Telematics, Qualcomm and American Medical Alert. The company will operate as a majority-owned subsidiary of Hughes Telematics and plans to launch a mobile Personal Emergency Response Service (PERS) focused on seniors and their caregivers in the United States in 2011.

“The mobile PERS solution will allow seniors to maintain their independence by providing them immediate, push-button access to emergency services,” said Qualcomm President Steve Altman in a statement. “Mobile PERS is a compelling offering that Lifecomm is well positioned to provide and we’re pleased to help enable.”

The mobile PERS device provides its wearers with one-touch access to an emergency assistance call center. Inside the device, a cellular modem will enable wireless voice and data communications while an embedded GPS and other sensors will enable location-based tracking and monitoring of the person wearing the device. A personalized Web portal for the users and caregivers will provide access to information about user activity and location.

The mobile PERS device will use Qualcomm’s Wearable Mobile Device module and wireless chipset technology. Hughes’ back office architecture and call center network will form the backbone of the Lifecomm service while American Medical Alert will handle distribution.

Lifecomm was first incarnated by Qualcomm as a healthcare-focused mobile phone service. Qualcomm pulled out of the initiative last summer after it failed to raise enough third-party capital to develop a product for launch.
