Frequency bands
The antenna is available for broadband. It can therefore be used for two different frequency bands that have been specified
for the regions of Europe and China/USA respectively.
● The antenna for Europe (EU, EFTA countries) operates in the frequency band of 865 to 868 MHz.
● The antenna for China, the USA, and Canada operates in the frequency band of 902 to 928 MHz.
Function
The SIMATIC RF640A is used for transmitting and receiving RFID signals in the UHF frequency band. The antennas are
connected to the SIMATIC RF600 readers via antenna cables that are available in different lengths.
