1.1 Key Features and Capabilities
 Multi-Frequency/Multi-Service RF Transport Platform: Accommodates GSM, UMTS,
HSPA, LTE, EDGE, EV-DO, and more. Three model-dependent bands per enclosure.
 Cost-Effective Higher Power: Optimizes and reduces the number of antennas required to
cover open and outdoor areas by offering 46dBm (GX-40 W) composite power per
frequency band.
 Operator-Grade Operation: Advanced signal handling and management ensures
operator-grade performance.
 Unique, space-saving non-obtrusive design: Blends into the environment and avoids
costly tower builds outdoors when covering campus scenarios, parking lots, tunnels and
indoor-adjacent outdoor space.
 Designed to withstand harsh environments - Fully sealed Remote Unit (RU) enclosure
ensures superior performance in harsh environments and worry-free electronics
maintenance. Compliant to IP65/NEMA standard.
 Management and control – alarm forward to NOC or standard EMS via SNMP, software
controlled output power and Optical link auto gain control

System Architecture
MobileAccessGX-Quad provides a complete solution consisting of GX-Quad remote units at the
remote locations, and head end elements, which are shared with any existing or new
MA1000/MA2000 deployment.
MobileAccessGX-Quad Remote Unit consists of a uniquely designed, non-obtrusive unit that
includes all of the required RF, F/O and power interfaces. All mobile services are distributed
through service/band dedicated RF connection ports over antennas installed at the remote
locations.
The following figure illustrates a scenario in which MobileAccessGX-Quad is installed alongside
MobileAccess2000 remotes and MobileAccessHX remotes. Note that all site elements are
managed and controlled via a single SC-450 Controller. All site elements (in this scenario
example), are controlled and managed by the SC-450 Controller that enables local and remote
management, and provides single-source, centralized „common head end‟ controls of MA1000,
MA2000, HX and GX-Quad elements.
In the downlink, at the head end, the BTS or BDA signal is conditioned by the RIU, ensuring a
constant RF level. The conditioned signal is then converted by the OCH-GX (GX Optical Central
Hub) to an optical signal for transport over single mode to the GX remote units, which are
located at the remote locations. In the uplink, the process is reversed. The SC-450 Controller
enables local and remote management, as well as controls all GX-Quad, MA1000 and MA2000
elements from a single, centralized location.
