Corning Restricted - Draft for public release Introduction CMA-xxx-AEN Page 11 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. 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. HX 2.5 GHz TDD Figure 1-1
Corning Restricted - Draft for public release Introduction CMA-xxx-AEN Page 12 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. • Operator-Grade Operation: Advanced signal handling and management ensures operator-grade performance in multi-operator deployments. • Design and Deployment Flexibility: Antenna splitting schemes are possible due to the higher power output capability. • Compatibility: Connects to existing MobileAccess1000, MobileAccess2000 and additional HX4 and HX WCS remote units to allow common antenna overlay; Shares a common headend and EMS in a single deployment) • Monitoring and Web Management: All status LEDs are located on front panel; Web management via the SC-450 controller (v7.3 and higher)
Corning Restricted - Draft for public release Introduction CMA-xxx-AEN Page 13 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.

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.
Corning Restricted - Draft for public release Installation Guidelines CMA-XXX-AEN Page 24 • 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). 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.

Corning Restricted - Draft for public release Appendix A: System Specifications CMA-XXX-AEN Page 54 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.
