RFID is one of emerging short-distance wireless transmission technology. RFID is Radio Frequency Identification, which can widely apply to non-stop charge system for safety forgery-proof、industry and commerce automation、property protection、logistics industry、park and highway.
Testing standard: ETSI EN 300 220 which apply to short-distant wireless communication equipment, is suitable for 25MHz to 1GHz frequency range and wireless equipment’ RF requirement of the maximum power below 50mW.
According to this standard, short-distant wireless communication products in this range can be divided into three kinds: Receiver class1、Receiver class2、Receiver class3
Receiver class1：High reliability short-distant wireless communication technology
Receiver class2：Middle reliability short-distant wireless communication technology
Receiver class3：Standard reliability short-distant wireless communication technology。
Usually our common short distance wireless communication product belongs to Receiver the class3 kind. The testing requirement for this kind’ product as following:
