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.
