4 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 bre
and output from the GE port on the RU. Each RU connects to an AP device through their
respective GE port. Thus, 6 independent Gigabit Ethernet transmission channels can be
completed. See Fig. 7 for connection details and Fig. 8 for application scenario.
The ow path of the signal is: Input LAN signals ↔ E-hub ↔ RU ↔ AP ↔ POI ↔ Antenna-
feeder system. The following applies:
● Each electrical port (GE1 to GE6) must correspond to an optical port (OP1 to OP6),
i.e. GE1 should correspond to OP1, GE2 should correspond to OP2, etc. WLAN signal
input on GE1 is then sent out on OP1.
● If there are multiple access points (AP) that are connected to more than one cascading
RU in a signal chain, the WLAN signal will only be output from one of the RUs, with the
priority being RU1 > RU2 > RU3 when selecting which RU the signal will be output from.
● If there is only one AP device, then the WLAN signal is always output from the RU that is
connected to the AP.
