HX 2.5 GHz TDD is a m id-po wer, rem ote s olution des igned t o be in tegrat ed into exis ting M obileAc cess 1000 (MA1 000)
and MobileAccess2000 (M A2000) Distributed Antenna S ystems (DAS) already deployed in the f ield. It is a fiber fed,
compact and scalable multi-service platform designed to complement the MA1000/MA2000 and other HX4 and HX
WCS remotes while prov iding complete RF open space coverage f or large-scale public venues such as cam puses,
stadiums, convention centers, hotels, airports and train stations.
Using low-loss fiber opt ic c abling, r em ote units can c over d istances of up to 1.4 mi (2 km ) f rom the BT S sig nal sour ces
at the headend. HX 2.5 G Hz TDD requires minim um addition of hardware to the headend (BT SC 2500) and utili zes
existing fiber and antenn a overlay. It also includ es test ports, enabling to measure the s ignals at the remote without
disconnecting the antenna cable and affecting services on the main stream. HX 2.5 GHz TDD MIMO takes full
advantage of MIMO technology by using spatial multiplexing to deliver higher s pectral efficiency and preventi ng the
degradation of quality while significantly increasing throughput on the same spectrum.

1.2 System Architecture
Figure 1-2 shows an example of SISO scenarios in a system topology where the HX 2.5 GHz TDD is connected to
existing HX4 and M A2 000 Q X rem otes . The HX 2.5 GHz TD D remote is installed bet ween the ex isting remote unit ( e.g.
HX, MA2000 QX) and the optical converter unit (i.e. OCH) and interfaces them both via fiber connections.
In the downlink, at th e headend, the BTS or BDA si gnal is condit ioned by the RIU, ensuring a cons tant RF level. T he
conditioned signal is then converted by the optical central hub (OCH) to an optical signal for transport over single mode
fiber to the HX, located at the remote location. In the uplink, the process is reversed.
The system controller (SC-450 v7.3) enables local an d rem ote m anagem ent, as wel l as co ntrols all MA1000 , M A2000,
and HX elements from a single, centralized location.

2 Installation Guidelines
This provides guidelines for installing the HX 2.5 GHz TDD remote unit.
2.1 Site Considerations
• The distance between the HX service antenna and the coverage area should correspond to LOS (Line of Sight)
requirements for maximum coverage area.
• The maximum fiber path loss is 3 dB.
• The system delay of the optical system must be taken into consideration when there are neighboring BTS sites
overlapping in coverage.
2.2 Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in
locations having stable temperature and unrestricted air-flow.
The installation location f or the system should be well ventilated. The equipm ent has been designed t o operate at the
temperature range and hu midity level as stat ed in the produc t specifications with a relative hum idity of max. 90% and
temperatures range of -20° to +60°C (-4° to 140°F).
2.3 Installation Requirements
• Mounting surface shall be capable of supporting the weight of the equipment.
• In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize
interference from electromagnetic sources such as large electrical equipment.
• Working space available for installation and maintenance for each mounting arrangement. Ensure unrestricted
airflow.
• Ensure grounding connector is within reach of the ground wire.
• Ensure a power source is within reach of the power cord and the power source has sufficient capacity.
• Where appropriate, ensure unused RF connectors are terminated.
• Do not locate the equipment near large transformers or motors that may cause electromagnetic interference.
• Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
• Ensure the equipment will be operated within the stated environment (refer to datasheet).
• Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.
• Observe handling of all cables to prevent damage.

2.4 Fiber Optic Requirements
2.4.1 Authorized Optic Cables
• Only single mode fiber can be used with HX 2.5 GHz TDD product
• All fiber in a given length of fiber must be of the same core diameter.
• All bulkhead adapters must be single mode SC APC (green) adapters.
• All terminations, cross connections or patches must be direct fusion splice or Corning specified patch cords listed
below.

2.4.2 Fiber Optic Rules
ATTENTION!
Please also refer to the laser safety section in the document preface.
• Fiber optic cables require proper handling. Do not stretch, puncture, or crush the fiber cable(s) with staples, heavy
equipment, doors, etc.
• Always maintain the minimum bending radius specified by the cable manufacturer. The minimum bend radius is
usually 10 times the cable's outer diameter. In the case of single optical fiber that is not in a cable, the minimum
bending radius to be observed is 30 mm.
• Use SC APC connectors (green color) 8 deg only.
• Pay special attention w hile c onnec ti ng the SC APC connectors - ensure that you hear a “click”, indicating a secure
connection
• Use minimum splicing/connectors to achieve minimum losses on the fibers.
• Use precaution while installing, bending, or connecting fiber optic cables.
• Use an optical power meter and OTDR for checking the fiber optic cables.
• Make sure the environment is clean while connecting/splicing fiber optic cables.
• All fiber optic connectors should be cleaned prior to connecting to the system
• Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are
terminated.
• Check the fiber optic connections.

• Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can
damage your eyes.
2.5 RF Coaxial Cable Guidelines
2.5.1 General Cable Installat ion Procedures
Note: The installer should be familiar with the ANSI/TIA/EIS-568 Cabling Standard guidelin es .
Observe the general cable installation procedures that m eet with the building codes in your ar ea. The building code
requires that all cablin g be installed ab ove ceiling le vel (where appl icable). The l ength of c able from the ris ers to each
antenna may need to be concealed above the ceiling.
The cable must be properly supported and maintained straight using velcro cable ties, cable trays and clamps or
hangers every 10 feet (where practical above ceiling level). Where this is not practical, the following should be
observed:
• The minimum bending radius of the supplied ½-in coax cable should be 7-in.
• Cable that is kinked or has a bending radius smaller than 7-in must be replaced.
• Cable runs that span less than two floors should be secured to suitably located mechanical structures.
• The cables should be supported only from the building structure.
• All cables shall be weather-resistant type
• Cable length - determined by the system installation plan. When calculating the cable length, take into account
excess cable slack so as not to limit the insertion paths.
.
2.5.2 RF Rules
• Use coax RG-223, 50 ohm, for RF connections between HX units and DAS antennas.
• When using the Corning system in an environment in which other indoor coverage systems are installed, it is
recommended (where possible) that the antennas are placed at least two meters apart
• When bending coax cables, verify that the bending radius does not exceed the coax specifications.
• Use wideband antennas supporting a range of 700 MHz to 2600 MHz
• Terminate all unused HX RF ports with a 50 ohm load
• Make sure that the VSWR measured at the coax cable meets the product specification The VSWR must be
measured prior to terminating the HX RF ports in the remote communication rooms.
2.5.3 Coax Cable Lengths and Losses
Use the compatible jumper to connect the coax connector to the external antenna.
Note: The required distance between the antennas (installed in the ceiling) depends on the infrastructure and
calculated path-loss.

3.3.3 Ground Connection
Required tools and components
The following additional (not supplied) tools and components are required for connecting the system ground:
• Grounding wire - grounding wire should be sized according to local and national installation requirements. The
provided grounding lug supports 14 AWG to 10 AWG stranded copper (or 12 AWG to 10 AWG solid) wire
conductors.
Note: The length of the grounding wire depends on the proximity to proper grounding facilities.
• Phillips-head screwdriver
• Crimping tool to crimp the grounding wire to the grounding lug.
• Wire-stripping tool to remove the insulation from the grounding wire
To ground the HX 2.5 GHz TDD remote
1. Use a wire-stripping tool to remove approximately 0.4 inch (10.9 mm) of the covering from the end of the
grounding wire.
2. Insert the stripped end of the grounding wire into the open end of the grounding lug.
3. Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to
the ground lug by holding the ground lug and gently pulling on the ground wire.
4. Prepare the other end of the grounding wire and connect it to an appropriate grounding point at the site to
ensure adequate earth ground.

OverPower Protection Mechanism
HX 2.5GHz-TDD have limiter mechanism in order to limit and maintain the output level to level.
DL limiter threshold shall be the same as “Max output target” value and the range shall be at least 6dB.
To prevent HX 2.5GHz-TDD UNIT system from damage due to output over power, an automatic shutdown mechanism shall be
implemented into the HX 2.5GHz-TDD UNIT and it shall continuously monitor its output power.
Overpower criteria - In case DL output power is higher than Max output power by more than 3dB for more than 5 seconds or HX
2.5GHz-TDD UNIT Overpower state identified - unit shall turn off service in order to prevent damage.
Recovery from overpower protection shall occur by estimating Output RF power by measuring input power and taking
attenuation status into account. If estimated output power is < (Max output power -3) than service shall be recovered.
Power Down Mechanism
• Over Current Protection ( OCP)
In order to avoid danger from overcurrent due to output load failure or short-circuit, over current protection is triggered at the
range above 110% of maximum output current in which turns the power to output current down. It will automatically recover the
current at normal current range (below 100% current load). (RCU + 12V)
In case of SLOT1 and SLOT2, E-FUSE mechanism blocks the current. (3.3A~3.6A/Each mechanism works independently.) and must
be recovered by actuating signal of RCU.
• Over Voltage Protection (OVP)
When output current are being operated above the rated voltage within the range of input current, over voltage protection are
triggered at 110% ~ 140% of rated output voltage and the device is shut down.
•
Input Terminal Circuit Protection
This circuit protects the PSU from being damaged by the over current when inverse polarity are connected to the input terminal.
• Short Circuit Protection(SCP)
Even if circuits are shorted while in operation, short circuit protection protects semiconductor devices within and in case of
SLOT1, SLOT2, E-FUSE mechanism blocks the current(3.3A~3.6A/Each mechanism works independently.) and must be recovered
by actuating signal of RCU.
