System Overview 3.3.3 E-Hub ● Receive the WLAN and small cell signals base station via 6 GigE Ethernet ports. ● Reframe with optical signal from the C-hub. ● Transmit the composite signal to next level E-hub and RU. Fig. 5: E-hub front view 3.3.4 HPRU...
WLAN Access (Wi-Fi) Each E-hub has 6 electrical ports, GE1 to GE6, which support up to 6 LAN signals. LAN signals are input on the GE1 to GE6 ports and output from the corresponding OP1 to OP6 ports. The signals are then transmitted to the RUs via optical signals over optical fibre and output from the GE port on the RU.
