Abstract
As the demands for information telecommunications increase, various technologies of wireless communications, which are not restricted by time and space, are applied in actual life. For Example, RuBee, Bluetooth, RFID(Radio Frequency IDentification), MIMO(Multiple Input Multiple Output), UWB(Ultra-Wide Band), Wi-Fi(Wireless-Fidelity), WLAN (Wireless Local Area Network), WLL(Wireless Local Loop), WiMAX(World Interoperability for Microwave Access), and Zigbee can be illustrated. Service diversification and data increase of mobile communications demand technology trends of broadband and high quality badly in need. To meet these demands, it is required to maximize the performances of wireless equipments and wireless networks.



For such improvements of information telecommunication equipments (ITEs), accurate test methods and test data are important factors. Currently, The measurement method technology standard of domestic wireless facility regulations, specifies that with the antenna separated from wireless test sample, the measuring equipment is connected to the final RF terminal of the test sample for the tests of antenna power and antenna power density(conductive power). But, it is difficult for the small equipment with internally installed antenna (intenna) to check accurate electrical characteristics. So, the necessity for ERP and EIRP measurement is required for a few years.



In this paper, the theory and introduction necessity of EIRP, and several national standards are mentioned. Also, measurement procedures, considerations in measurement and the results utilizing “Substitution EIRP/ERP Measurement System which is proposed as an automated measurement system based on EIRP theoretical background, are described. In conclusion, if the automated measurement technology, proposed in this paper, is standardized, it is considered that this method can be an accurate measurement method for miniaturized RF application equipments, and limited RF sources can be utilized efficiently.
