3.0 Installation Procedure
3.1 Hubs
The Hub(s) should be located as close as possible to the donor BTS. Observe
all environmental specifications for the hub to avoid damage from moisture, heat,
cold, etc.
3.2 Remotes
Ensure that each remote location is correct according to the system design
drawings. Observe all environmental specifications for the remote to avoid
damage from moisture, heat, cold, etc.
3.3 Pre-installation
Prior to installation, a carefully planned system layout should be documented. At
a minimum, this document should include the location of the Hub, the location of
the Remotes, the Antenna locations, the fiber locations and lengths, and the
location of the power supplies for both Hubs and Remotes.
The Hub is located at the Building Base Station or BTS. The Hub interfaces with
the user's PCS System. The Remote units are distributed in the building and
provide signal coverage. Optical fiber cables connect the Hub to the Remote
units. The Hub can be powered with +24 VDC from the BTS, or with an optional
power supply providing +48 VDC, 90-130 VAC, or 190-270 VAC. The remote AC
power supply will power up to 16 Remotes.
Two optical fibers are required for each remote unit; each Hub can connect to up
to eight Remote units. Angle-polished SC/APC connectorized optical fiber cable
must be installed in the building. Any optical connector used between the Hub
and the Remote units should be an angle-polished connector specified for return
loss >55 dB. Fusion splices to connect fibers are also suitable. Flat polished
connectors anywhere along the optical fiber path will degrade the system
performance.
