WAN Protocol 2
Purpose – Move the data from the local
environment elsewhere
•WAN Sender
– Collocated on the AHD in the home environment
– Converts IEEE 11073 representation to HL7 2.6 form
– Sends data using IHE PCD-01 transaction
•WAN Receiver
– Sits in the web services of a professional organization
– Collects data from the WAN Sender
– IHE PCD-01 transaction
