• Introduction MobileAccessHX WCS 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.
1.1 Key Features and Capabilities • Service Platform: Accommodates LTE and provides SISO/MIMO configuration for WCS band. • Cost-Effective High Power: Optimizes and reduces the number of antennas required to cover open areas by offering up to 33 dBm (2 W) composite power per frequency band. • Scalability: Supports either SISO or MIMO service in a single compact enclosure.
1.2 System Architecture MobileAccessHX WCS provides a complete solution consisting of HX remote unit(s) at the remote locations and headend elements. 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 Base Unit (BU) to an optical signal for transport over single or multi-mode fiber to the HX remote unit, located at the remote location. In the uplink, the process is reversed.
1.3 System Monitoring and Management The HX WCS remote unit is centrally managed via the SC-450 Controller (v7.2 and higher). Note that HX is not directly connected to the controller. The HX is managed and configured via the BU to which it is connected Figure 1-3 shows the Configuration tabs of the selected HX unit. Refer to the SC-450 Controller User Manual (v7.2 and higher) for information on how to configure and manage the HX WCS remote unit.
1.4 HX Unit Description The HX WCS unit consists of the following main modules: • RCU – Remote Control Unit; Includes status LEDs for each module and control ports • HX-WCS MUX – Multiplexer [ANT. 1 MUX (right) for SISO; ANT. 2 MUX (left) for MIMO] including interfaces to RF antennas and to MA1000/MA2000 units; combines signal sources additional external RF signals (when connected to HX unit and MA1000/MA2000 remote) while providing the proper filtering into a single antenna port • HX Module – [ANT.
1.4.1 HX WCS External Interfaces The HX WCS front panel includes the multiplexer interfaces (e.g. antenna port, DL Test port, wideband RU port), system level status LEDs and service maintenance ports. Note: Both SISO and MIMO models include two sets of multiplexer RF interfaces. For SISO models, the RF connections will be performed via the connectors corresponding to the installed HX remote unit module (inside chassis): Left MUX for Left HX WCS Module and Right MUX for Right HX WCS Module. (See section 1.
Refer to Figure 1-6 and Table 1-2 for description of HX status LEDs. HX WCS RCU Module Status LEDs Figure 1-6 Note: Module 1 and Module 2 LEDs correspond to installed modules [Module 1 for ANT. 1 (SISO); Module 2 for ANT. 2 (MIMO)].

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 WCS output signal. The module includes a 1:4 splitter for the high band (i.e. WCS) and four internal diplexers that combine the 2.3 GHz signal with the wideband signal received from the MA1000/MA2000 remote.
• Installation Guidelines This chapter describes the installation procedure for the HX WCS remote unit. 1.6 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. 1.
1.9 Fiber Optic Requirements 1.9.1 Authorized Optic Cables • Only single mode fiber can be used with HX WCS 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. 900 microns pathcord for splicing, 2 Meters, 2xSC/APC Diamond p/n ENC/1045341 Beige boots, 62.
• 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. 1.10 RF Coaxial Cable Guidelines 1.10.1 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).

1.17 Connections Note that the HX WCS is an upgrade unit and as such the RF and fiber connections also interface the existing MA1000/MA2000 remote units. Where relevant, the RF and fiber connections reference existing HX and MA2000 QX as examples of connections to existing remotes. 1.17.1 RF and Fiber Connections 1.17.1.1 Installations with Additional HX Unit 1. Connect the HX WCS MUX “WB RU” 4.3-10 Type duplexed RF port to the HX duplexed antenna port.

1.17.1.2 Installations with MA1000/MA2000 Remote This section provides instructions on how to perform expansion connections between the HX WCS unit and an MA1000/MA2000 remote unit. The RF connections between the HX WCS unit and an MA1000/MA2000 remote require an EPM unit which interfaces between the HX WCS and the service combiner unit (SCU) required for the MA1000/MA2000 remote. IMPORTANT! Port. Two EPM units are required for MIMO installations – each one connects to an HX WCS ‘ANT.
2. Connect the four rear panel EPM low-band N-Type input ports to the corresponding SCU N-Type ANTENNA PORTS”. Note: The location of the SCU ‘ANTENNA PORTS” differ depending on model: • SCU-4/SCU-8 units - antenna ports located on rear panel • SCU-F/SCU-FT - antenna ports located on front panel Example of Connection between HX WCS and EPM Figure 3-24 3.

Note: EPM and SCU not shown in Figure 3-17 for clarity. 1.17.2 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.
1.17.3 Power Connections WARNING! Before connecting or disconnecting ground or power wires to the chassis, ensure that power is disconnected from the DC circuit. To disconnect power, locate the circuit breaker on the panel board that services the DC circuit, and switch the circuit breaker to the OFF position. Verify zero voltage at the power terminals on the chassis before proceeding.
• Identify the positive and negative terminals on power source feed positions. The wiring sequence is positive to positive and negative to negative. • Open the terminal block screw and insert appropriate feed into the terminal block plug • Torque the terminal block captive screw (above the installed wire lead), using a ratcheting torque screwdriver. Recommended torque is 0.49N•m. • Repeat above steps for all feeds • Insert the plug into HX WCS PSU DC terminal block. 1.
