1 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.
1.1 Key Features and Capabilities • Service Platform: Accommodates LTE TDD and provides SISO/MIMO configuration for the 2.5 GHz TDD 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 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.
Figure 1-4 shows an example of MIMO 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. MIMO configurations require one line of fiber for each MIMO stream and one EPM for each stream in installations with MA1000/MA2000 remotes. HX 2.
1.3 System Monitoring and Management The HX 2.5 GHz TDD remote unit is centrally managed via the SC-450 controller (v7.3 and higher). Note that HX is not directly connected to the controller but managed and configured via the OCH to which it is connected. Figure 1-4 shows the main configuration window for the selected HX 2.5 GHz TDD unit. Note: Refer to the SC-450 controller user manual (v7.3 and higher) for information on how to configure and manage the HX 2.5 GHz TDD remote unit. Example of HX 2.
1.4 HX Unit Description The HX 2.5GHz TDD unit consists of the following main modules: • RCU – Remote control unit; Includes status LEDs for each module and control ports • ANT (MUX) – Multiplexer [ANT. 1 MUX (right) for SISO; ANT.
1.4.1 HX 2.5 GHz TDD External Interfaces The HX 2.5 GHz TDD 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 2.5 GHz Module and Right MUX for Right HX 2.
Refer to Figure 1-7 and Table 1-2 for description of HX status LEDs. HX 2.5GHz TDD RCU Module Status LEDs Figure 1-7 Note: Module 1 and Module 2 LEDs correspond to installed modules [Module 1 for ANT. 1 (SISO); Module 2 for ANT. 2 (MIMO)].
1.4.2 Internal Module Interfaces The HX internal modules include two main modules (see Figure 1-8): • PSU – Power supply module; includes DC In connector and status LEDs • HX Module – one for SISO cabinets and two for MIMO (the interfaces are the same for each module); comprises an optical module and power amplifier; interfaces to the base unit; Left HX Module 2 (MIMO) corresponds to left HX MUX and right HX Module 1 (SISO) corresponds to right MUX. HX (MIMO) Internal Modules – PSU (Left) and HX 2.

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.
2.4 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. 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. 2.5 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).
