1 Introduction
Radio Hub Unit (RHU) is a part of the Hybrid Distributed Antenna Systems (HDAS) to provide RF link
solution between RF Source and Remote Unit (RU). This RHU receives RF signal over-the-air or wire line
and this unit filters, amplifies and converts RF signal into optic signal and transmits to child unit such as
FHU and RU through single mode fiber. RHU is built on a small form factor with six antenna ports for
700MHz, 850MHz, 1900MHz, AWS band and two GPS antenna ports with the following features
Support for a multi frequency band, multi-technology and multi-carrier
Wide band sub-channel selection by digital filter
Antenna isolation detection and oscillation protection function
Low Power consumption that can be operated by PoE or small AC/DC converter
20dBm Up Link composite power per band
SNMP based remote management support
Provide signal to remote unit(RU) site as far as 10Km distance that has 5dBo loss via single mode
fiber
Optic fiber sharing between different carriers

2 Product Description
Radio Hub Unit (RHU) is a part of the Distributed Antenna System (DAS) to provide link between RF
Source and DAS RU, to fill coverage gaps and to enhance the quality of service of extending coverage of
mobile service.
As shown in Figure 2-1, RHU is a compact platform with the natural heat convection. As unified form
factor, RHU services multiple technologies on a single platform with 700/850/1900/2100MHz
Quadruple-band and GPS L1 band frequencies reception. It can be mounted on the wall or 19” rack.
Variety of the donor antenna can be used from Yagi directional antenna to high F/B Ratio directional
antenna (or panel antenna).
Figure 2-1 RHU system
2.1 Network configuration
Four band RF signals such as 700/850/1900/2100MHz or 2 GPS L1 band from link and GPS antenna are
fed to RHU and RHU amplifies these RF signals and converts into optical signal, and transmits this optical
signals to child unit likes FHU or xRU. RHU can have up to 16 RUs and 5 FHU connections.
A fiber optic cable can be shared between different carriers or different band. Each frequency band
signals are combined to one wavelengths in a single fiber. Table 2-1 describes those wavelength
assignments. Maximum allowed optic loss between RHU and RU system is 10 dBo.

Locate the equipment with the space for the sufficient airflow to prevent build-up from
the overheating. Do not compromise the amount of airflow required for safe operation of
the equipment.
Verify the power connection and Fiber cables prior to turning on the systems.
WARNING: Equipment loading must be verified prior to mounting the equipment on the wall or 19”
rack.
3.1.1 General Safety Precautions
The following precautions apply to the RHU:
The units have no user-serviceable parts. Faulty or failed units are fully replaceable through
Intelibs.
When the Fiber cable is connected to the equipment, the connectors must be free from the dust
and connected according to the cable manufacturer’s instructions. (WARNING: For the safety,
DO NOT conduct eye-contact at the connector ends of the fibers or the port of the RHU and SRU
unless equipped with protection goggle. Invisible infrared radiation may be present at the front
panel of the RHU and SRU. Do not remove the fiber port dust caps unless the port is going to be
used. Do not stare directly into a fiber port.)

4 Configuration and Maintenance
RHU can be configured in three ways via remote internet connection or local serial port connection.
Local management interface through the internet and serial connection.
Web interface through the internet
SNMP interface through the internet
Master Unit is a remote management system that provides SNMP v3 and Web interface, and maintains
all functions of iDAS system including configurations, monitoring, and real time alarm reporting.
LMT (Local Management Terminal) is local management interface through serial interface.
The configuration and maintenance for RHU is performed by accessing RHU through any interfaces.
Figure below describes a typical iDAS management system network and the entities and management
system network of RHU-iDAS is a part of total DAS management. Red marked part is the management
network of RHU iDAS system.

4.3 Firmware download
Firmware download is performed when system needs to be updated.
Downloading improper images (executable file of repeater CPU) may cause harmful damages to
equipment.
4.4 Additional function of RHU
4.4.1 ASD (Auto Shutdown) Function
1. If UL output power level of RHU is above the shutdown level longer than 1 second, RHU
automatically turns off amplifier to protect undesirable transmission.
2. During shutdown state, monitor RU input power. If the level is below5dBfrom shut down level,
turns on UL amplifier automatically.

4.4.2 ALC (Auto Limit level Control) Function
1. If UL output power level of RHU reaches the ALC level, RHU decrease the output power to
maintain ALC level automatically.
2. When power level goes down under ALC level, RHU increase output power until ALC ATT is 0 by
500msec ~ 1sec speed.
4.4.3 AGC (Auto Gain Control) Function
1. In order to have stable output power, RHU has AGC function that can maintain constant output
power with setting output level.
2. When input level is decreased RHU increase gain to maintain continuous output level, when

input power is increase RHU decrease gain to have same output power automatically.
3. RHU works AGC function by 500msec ~ 1sec speed.
4.4.4 Sub-band selection Function
RHU can select sub-band up to 10 bands in 65MHz bandwidth using digital filter function. These sub-
band filters have very sharp cut-off characteristics and RHU can provide the signal of selected band of
65MHz BW to coverage area. This digital signal processing function also provide input signal information
and antenna isolation information between link and coverage antennas.

5 Human RF Exposure and Antenna placement guide
Actual distance is determined upon gain of antenna used. Please maintain a minimum safe distance of at
least 40 cm while operating near the donor antennas with the maximum permissive antenna gain up to
18 dBi and 8.45 dBi for the 1710-1755 MHz frequency band.
Note: According to Part 27.50 (d)(4), fixed stations operating in the 1710-1755 MHz band are limited to a
maximum antenna height of 10 meters above ground.

Limited Warranty
Intelibs, Inc. (“Intelibs”) offers a standard two year warranty from defects in material and installation. INTELIBS may at any time
exclude from this Agreement any Hardware or Software which (1) has been modified, repaired or serviced by anyone other than
Intelibs’ service staff without the prior written approval of Intelibs, (2) has been subjected to unusual physical or electrical stress,
whether such stress results from accident, neglect, misuse, lightning, failure of electrical power, air conditioning, humidity control,
transportation, the making of specification or configuration changes requested by Customer, or any other cause other than ordinary
use, and whether or not such stress is the fault of the Customer, (3) has been purchased from another Vendor and is networked,
linked, attached or otherwise intended to work with the System or (4) has been moved from the place of installation. When the
system has been improperly modified, repaired, stressed, used or moved as described above, Intelibs may, at its option and subject
to the approval of the Customer, perform such corrective work, including any repairs, replacements and adjustments, as are in
Vendor’s opinion necessary to restore the System to the condition it would have been in if subjected only to normal wear and tear
at the Customer’s expense.
