Introduction
HX 2.5 GHz TDD is a mid-power, remote solution designed to be integrated into existing MobileAccess1000 (MA1000)
and MobileAccess2000 (MA2000) Distributed Antenna Systems (DAS) already deployed in the field. 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 providing complete RF open space coverage for large-scale public venues such as campuses,
stadiums, convention centers, hotels, airports and train stations.
Using low-loss fiber optic cabling, remote units can cover distances of up to 1.4 mi (2 km) from the BTS signal sources
at the headend. HX 2.5 GHz TDD requires minimum addition of hardware to the headend (BTSC 2500) and utilizes
existing fiber and antenna overlay. It also includes test ports, enabling to measure the signals 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 spectral efficiency and preventing 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 MA2000 QX remotes. The HX 2.5 GHz TDD remote is installed between the existing 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 the headend, the BTS or BDA signal is conditioned by the RIU, ensuring a constant RF level. The
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 and remote management, as well as controls all MA1000, MA2000,
and HX elements from a single, centralized location.

1.5 External Passive Module (EPM)
The external passive module (EPM) is required when in installations with an existing MA1000/MA2000 remote unit (e.g.
MA2000 QX). The EPM is used to combine up to four low band output wideband signals with the high band HX 2.5
GHz TDD output signal. The module includes a 1:4 splitter for the high band (i.e. 2.5 GHz TDD) and four internal
diplexers that combine the 2.5 GHz TDD signal with the wideband signal received from the MA1000/MA2000 remote.
The EPM interfaces to the HX 2.5 GHz TDD and to the service combiner unit (SCU) of the MA1000/MA2000 remote.

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 while connecting 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.

RF Coaxial Cable Guidelines
2.5.1
General Cable Installation Procedures
Note: The installer should be familiar with the ANSI/TIA/EIS-568 Cabling Standard guidelines.
Observe the general cable installation procedures that meet with the building codes in your area. The building code
requires that all cabling be installed above ceiling level (where applicable). The length of cable from the risers 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.

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.
