The rack-mountable Host Unit is typically located
at a Base Station or a facility housing a suite of
Base Stations. On the forward path, the Host Unit
receives the RF signal from the BTS and digitizes
the designated RF band and digitally transports it
over singlemode fiber or a millimeter wave link to
a Remote Unit. In the reverse path, the Host Unit
receives the digitized RF signal from the Remote
Unit and converts it back to RF for the BTS.
The URH Host Unit is completely modular in
design, with all major modules; SeRF (Serial RF)
card, DART (Digital/Analog Radio Transceiver)
card, Power Supply, System board and Fan being
hot swappable.
The URH Host Unit supports up to eight DART
cards (supporting up to eight remote units) and is
capable of simulcasting signals up to as many as
eight Remote Units.
The Host Unit utilizes an embedded element
management system for system configuration
and network monitoring. The embedded EMS
collects alarm information from both the Host and
Remote Units. For multiple link deployments,
multiple Host Units can be networked together at
the same BTS site. Host Units can be
daisy-chained together to allow monitoring and
control of multiple Remote Units from a single
user interface.
In addition to sending alarm notifications to the
Element Management System (EMS) through
software, the URH Host Unit also features front
panel alarm reporting. LEDs on the front panel of
the Host Unit will change color depending on the
status of the unit. LED displays provide
information regarding the following items:
Power
System mode (active/standby)
Indicate faulty unit
RF conditions

The URH Remote Unit utilizes a modular
design, which supports up to three bands.
Each side panel/door represents a single
band allowing for future upgrades and easy
field access. Mounting options for the
Remote Unit include: pole-mount, inside
pole-mount, wall-mount, strand-mount
(singe-band unit only), and sub-terrain
vault-mount.
The URH Remote Unit is a fully sealed IP-65
rated enclosure, which minimizes
maintenance and is ideal for harsh
environments. Fiber, antenna, and power
input/output connectors are all sealed for
maximum protection.
On the forward path, the Remote Unit
receives the digitized spectrum from the
Host Unit and converts the spectrum back
into RF to be distributed via an externally
mounted antenna system. On the reverse
path, the Remote Unit digitizes the
designated RF spectrum and digitally
transports it over singlemode fiber or MMW
to the Host Unit.
In addition to sending alarm notifications to
the EMS software, the URH Remote Unit
also features LED alarm reporting. An LED
on the bottom of the Remote Unit will
illuminate upon a fault condition.
