This version of the Continua Design Guidelines (CDG) includes guidelines for the Personal Health Devices interface (PHD-IF), the services interface known as the Services-IF and the Healthcare Information System interface (HIS-IF).

These guidelines for PHD-IF also include design guidelines on the use of a transport technology i.e., Near-Field Communication (NFC), USB, Bluetooth Basic Rrate (BR)/Enhanced Data Rate (EDR), Bluetooth Low Energy (LE) and ZigBee for a specific certified capability. An overview of the capability classes defined under each of these transport technologies.

Services-IF guidelines (see [H.812]) are defined for capability classes using different transport technologies such as simple object access protocol (SOAP), RESTful HTTP and message queuing telemetry transport (MQTT).

HIS-IF guidelines (see [ITU-T H.813]) are defined for capability classes using different transport technologies such as IHE XDR, IHE XDM and DIRECT.
