MobileAccess 2000 provides a cost effective solution that enables multi-operator indoor coverage
of voice and data wireless services through a single coax antenna infrastructure. MA 2000
provides scalable indoor coverage for enterprises, where support for coverage from additional
operators in any band range, for example CELLULAR 800MHz band and GSM 900MHz band, may
be added as needed, without changing the infrastructure. Thus, subscribers of any operator (for
whom coverage is provided) may have excellent wireless voice reception at any point in the
building, as well as use of the network through 802.11a/b/g data services.
Two types of remote location systems are available:
• 2000 Lite – supports up to 8 services
• 2000 Cabinet – supports up to 20 multi-operator services
The MA 2000 system can be remotely controlled and managed from a single location through MA
410/430 Controllers.

System Architecture
Features and Capabilities
•Support for all current and future technologies such as TDMA, CDMA, WCDMA and GSM, and
services such as PCS/CELLULAR, Paging, iDEN and 802.11 (a/b/g) Wireless LAN
easily
• Scalable and future-safe – can
• Remote end-to-end monitoring through MA 410/430 controllers
• All active components are located in the communication closet/room
• Simple installation and commissioning
be upgraded to provide support for additional services
1.1 System Architecture
At the head-end, MobileAccess elements provide the interface to the wireless service provider’s
network, condition the signals, convert them from RF to optical and transport them over the
optic fiber infrastructure to the remote end.
At the remote end, MobileAccess elements receive the optical signal transmitted from the head
end, convert the signal back to RF, amplify and filter the signals and then combine them for
distribution over the broadband antenna infrastructure.
Introduction to the MA 2000 System
Controllers installed at the head-end provide direct interface to the MA elements and through
them, provide end-to-end control over the remote end elements.
1.1.1 Head-End Elements
The following elements are installed at the BTS/BDA side:
•MA Remote Interface Unit (RIU) – Receives and combines RF inputs from one or more
cellular networks via off-the-air repeaters or Base Transceiver Stations (BTS).
NOTE: Interface to the BTS/BDA may also be passive (i.e. Interface Box).
•Base Unit (BU) – Receives the combined signal from the RIU and converts it to an optical
signal for distribution over fiber optic cables to multiple MobileAccess Remote Hubs.
NOTE: These elements are not specific to the MA 2000 system. They are common to other MobileAccess
systems.
1.1.2 Remote Locations Elements
The following elements are installed at each remote location:
•Service specific units that are either housed internally in an MA 2000 Cabinet or connected
externally to an MA 2000 Lite device. Two types of units are available:
•Remote Units (RU) – supports two voice services and performs the optic to RF (and
vice versa) conversion, amplification and filtering at the remote locations. An third
service can be added through connection to an MA 1200 Add-on unit.
MA 2000 Installation and Configuration Guide 2
System Architecture
•MA 1200 Add-on – supports a single voice service. It enables a host RU to which it is
connected to provide an additional service.
•MA 850 – flexible and maintainable wireless transport platform that enables large-scale WiFi deployments and distribution of data services from 802.11a/b/g APs through the same
antennas as the voice services.
•MA 2000 Cabinet – houses up to five units (RUs and MA 1200 add-on), converges the
corresponding services (up to 20) and provides the interface to the coax antenna
infrastructure. (MA 850 can also be added externally)
•MA 2000 Lite – provides connections to two RUs, where MA 1200 add-on units may be
connected to the RUs to provide support for up to 8 services. (MA 850 can also be added).
•Antennas – wideband MobileAccess antennas
1.1.3 Management Elements
The following elements provide remote management for the MA 2000 system elements:
•MA 410/430 Controller – The controller provides the interface between the system
elements and the management and control mechanism.
•MCT – a Java based GUI application provided with both controllers. MCT is used to
setup the system elements and to provide basic management functions.

software application that provides enhanced monitoring and control capabilities for all

System Architecture
1.1.4 System Operation
Figure 1-2 shows a basic block diagram of the system operation. On the downlink, the services
from the BTS/BDA are transferred via interface to the Base Units. The interface, which may be
passive (i.e. Interface Box) or active (RIU), is used to attenuate the RF signals to the required
levels, converge them and distribute them to the BUs.
service specific.
At the BUs, the RF signals are converted to optical signals and transmitted over the optic fiber to
(service-specific) RUs at the remote locations. At the remote locations, the RUs, which are either
housed in an MA 2000 Cabinet or externally connected to an MA 2000 Lite, reconvert the optical
signal to RF. At the 2000 Cabinet/Lite, the services are converged and distributed over the coax
antenna infrastructure. Data services from 802.11/a/b/g APs may be integrated into the MA
2000 system at the remote locations. MA 410/430 provide monitoring and control of all active
system elements.
Introduction to the MA 2000 System
The BUs are wideband – they are not
Figure 1-2. Basic Block Diagram of System Operation
MA 2000 Installation and Configuration Guide 4
Application Example
1.2 Application Example
Figure 1-3 shows an example of an MA 2000 Cabinet based solution. Five services from two
different operators are distributed, where services from Operator A conflict with those from
Operator B.
The converted optical signal is routed from the BUs directly to the corresponding RUs in each
Cabinet over optic fiber. Each BU supports connections to 8 RUs. Additional BUs are required for
connection to more RUs.
Services 1 and 2 are distributed through the foremost RU in each Cabinet. Services 3, 4 and 5
are distributed through the second RU and the MA 1200 unit connected to that RU.
MA 850 converges 802.11a/b/g data services with the voice services to be distributed through a
common infrastructure of coax and wideband antennas.
