- Today, the wirelesscommunication systems areused for many vitalapplications. Asconsequence of thenetworked society and anincreased use of wirelesselectronical equipmentemphasized by 5G PPP,common ambient assistedliving home platform(CAALHP) for aged peoplewas developed.- In 2010, it was reported byresearchers from CaliforniaCancer Center that RFIDreaders help to enhancepatient experiences#.

5G PPP will drive the future

networked society

The innovative RFID solution allows to reduce

stress and to improve facility efficiencies in the

hospitals#.

- Solution to avoid heavy bureaucracy:

All patient data is kept in an electronic

file on the central database server#.

- In the internal medicine departments of German hospitals,

29,000 patients die each year as a result of being given the wrong

medication, according to a study made by the Medical University

of Hanover##.

- Moreover, every year, the medication errors and wrong

treatments cost the health system several million dollars###.# “Healthcare transformation”, Asian Hospital & Healthcare Management, No. 29, 2014## T.

- The patient treatment was considerably improved with the correcttransfusion in exactly the prescribed quantity after use of RFID readers #.

- Using mobile devices, the doctors can access easily all the medical data,such as case history, diagnoses, lab reports, allergy results, via thepatient number and WLAN at any time ##.

- Currently, initiatives to forecast for standardization of new telemedicinecommunication system were launched # # #.

- Need for the platform offers a friendly environment and guarantees anaccurate management with less human errors for medical services inhospitals and homecare*.

Facing up to such needs, the CareStore platform#,## is proposed inthe frame of FP7-SME program. It is an user friendly online e-healthcare platform. Its innovative aspect lies particularly on:� The easy deployment of applications and device drivers within

the Healthcare domain� The possibility to increase homecare efficiency, reduce costs and

provide a higher degree of flexibility to users� The improvement of living standards and independent life of the

elderly population� The integration of wireless communication interfaces for the

data transmission� And to forecast for standardization of new telemedicine

communication system

Radiated EMC emission test (Std EN55022): experimental setup

for the emission test

- In the ½ anechoic room, the DUT was placed on the 360° turn

table at the standardized distance for the emission antenna.

The system was moved in order to check the maximum peak of

the emission in all direction from 30MHz to 1GHz. To cover this

wide frequency range two different antennas were used.

- The overall system in the ½ anechoic room was controlled from

outside. Then, the measured data are stored via the acquisition

and calibration tool ACCSYS-EMCTM from HAMERA RF.

- To check, the functionality of the overall system, the

experimental setup was permanently visualized with a survey

camera.
