Overview
The CrossFire system includes the Access Unit (AU), Expansion Unit (EU) and Remote Unit (RU).
Using digital processing and digital optical transmission technology, the AU frames radio-frequency signals from base
stations of different operators, and of different standards and frequency bands, and transmits the composite signal to
the EU. WLAN and small cell base station signals access the gigabit/megabit Ethernet port on the EU and are reframed
with optical signals from the AU and then transmitted to the RU. The RU conducts digital-analog conversion and power
amplification of the input signals and then achieves radio coverage through the antenna-feeder system for signals of all
standards and frequency bands.
