Cambridge Consultants Ltd. has launched software to provide wireless connectivity between a medical device and online health services conforming to the Continua Health Alliance standard. The product combines a wearable mobile phone from Qualcomm Inc. with Cambridge Consultants’ Vena software stack. This arrangement enables data collection from Continua-certified devices over the Continua Personal Area Network (PAN) interface and data transmission over the Continua Wide Area Network (WAN) interface to online health services.

Qualcomm Wearable Mobile Device 1X, 1X EV-DO and UMTS modules support a variety of 3G networks and provide integrated GPS capability, an accelerometer and Bluetooth technology. With data and voice support, a standard USB 2.0 interface, defined APIs and a development kit, the modules are claimed to provide unprecedented functionality and streamlined 3G connectivity for M2M and CE devices.

The Vena wireless healthcare software stack embeds the Bluetooth Health Device Profile (HDP) and IEEE 11073 standards for the exchange of information between health devices. According to Nick Vassilakis, a business development consultant at Cambridge Consultants, the Vena software stack is designed to use emerging industry standards and enable the rapid development of compact, low-cost wireless health care devices.

The Continua Health Alliance is a non-profit, open industry coalition of healthcare and technology companies with more than 200 member companies. The Continua Design Guidelines specify how to use existing standards to build interoperable personal health care solutions. The group's version 1.5 design guidelines add the definition of the WAN interface and include two additional wireless technology standards for low-power radios.
