1.1 About MobileAccess™ 2000
MobileAccess™ 2000 converged wireless networks solution provides scalable in-building
coverage for multiple wireless data and voice services through a single coax and broadband
antenna infrastructure.
The solution is based on combining a number of services, both voice and data, at each
covered location. The services, supported by remote units are combined and interfaced to a
common antenna infrastructure.
Figure 1-1. MA 2000 System Overview
Voice services are transmitted between the BTS side and the locations via optic fiber after
the appropriate conversion from RF to optic, and reconverted to RF at each end. The MA
2000 scalable solution is available in various configurations designed to meet the needs of
sites of various sizes:
• Remote Cabinets – The remote cabinet is designed for larger sites requiring future
safe support for several operators. The remote units supporting the services are
compactly housed inside a cabinet that provides the required interfaces, filtering and
combining functionalities.
• 2000 Lite – The 2000 Lite is designed to provide coverage for smaller sites with
fewer services, or as an entry-level solution for larger sites. This solution provides
support for a few services implemented by one or two remote units. The remote
units in this configuration are installed externally to the enclosure.
Wireless 802.11/a/b/g coverage may be integrated into the MA 2000 system (either
configuration) using the MA 850 remote module (that supports wireless LAN service
distribution).
Installation and Configuration Guide 1
Introduction
To optimize system coverage under changing environmental conditions or load, as well as to
enable remote monitoring of all system elements from a central location, MobileAccess
provides the following MA 2000 system enhancement solutions:
• Manageable BTS interface devices that control the level of the BTS signal fed into
the system (Radio Interface Unit)
• Network Management System (NMS) consisting of controllers, adjustment and
management software
1.1.1 Features
• All services are distributed through a
single
coax and antenna infrastructure
• Each Remote Cabinet can house up to five remote units supporting up to 20 services
including 3G and 802.11a/b/g
• Each 2000 Lite supports up to two remote units to which MA 1200 add-on modules
may be connected, providing support for up to 8 services
• 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
• Scalable and future-safe – additional remote units can
easily
be installed
• Support for remote monitoring through MA 410/430 controllers
• All active components are located in the communication closet/room
1.2 System Architecture
The MA 2000 solution is based on the following main elements:
• MA Base Units (BUs) – The BUs perform RF to optic conversion on the BTS side.
• MA Remote Units (RUs) 2000 – The MA 2000 performs the RF to optic signal
conversion at the antenna side for up to two services corresponding to the RU
model. A third service can be added by connecting an add-on remote hub unit (MA
1200) to the RU 2000. The RUs are housed in the 2000 Remote Cabinet.
• MA 850 – The MA 850 is a wireless LAN module that provides secure and
centralized connections for 802.11a/b/g Access Points and distributes the wireless
services over the same coax and broadband infrastructure as the voice services.
All services are combined and distributed through the same antenna broadband
infrastructure.
2000 Lite which can support two RU 2000 modules (and MA 1200 add-on units) may be
used as an entry point for sites that support a minimal number of operators. This installation
is future safe and can easily be upgraded to support additional operators or services (using
MA Remote Cabinet configuration).
To provide optimum coverage at all times and monitoring and control of all system elements
from a central location MA provides the following devices:
• MA Radio Interface Units (RIUs) – The RIUs provide interfaces for up to three
BTS/BDA signals, and automatically adjusts the output signal in respose to input
signal level in order to provide optimal coverage.
• MA 410/430 controllers – The controllers enable remote monitoring of the
system elements from a
single location
via advanced intuitive GUI.
2 Installation and Configuration Guide

Introduction
1.3 MA 410/430 Remote Management
The MobileAccess (MA) Network Management System (NMS) provides complete site
coverage and network management. It can be used to provision coverage that can
compensate for changing loads. It also provides real-time monitoring, control and
diagnostics capabilities for
MobileAccess
devices from a single location.
NOTE: The MA NMS System is fully described in the MA NMS System Configuration and
Operation Guide.
The MA NMS system consists of:
• MA 410/430 Controller – The controller provides the interface between the
system elements and the management and control mechanism. Two controller
models are available:
MobileAccess 410™ – enables management of the connected devices through a local
or point-to-point dial-up connection. It can be remotely managed through a
connection to the MobileAccess 430 controller.
•
•
•
•
MobileAccess 430™ – enables management of all connected elements and all
connected MA 410 controllers and the corresponding elements. Supports SNMP
(Simple Network Management Protocol) over TCP/IP connection.
MA 430 may be managed through the Network Operator Center (NOC) through
Manager of Mangers element such as HP OpenView via SNMP.
• MCT – a Java based GUI application provided with both controllers. The MCT is
used after the installation procedure to adjust MobileAccess devices according to the
installation site characteristics in order to optimize coverage for the site.
The application is installed and ran from a computer that is connected either locally or
via remote dial-up modem to the controller site to be adjusted or monitored.
• MobileAccess Manager™ – a Java based GUI software application that provides
enhanced monitoring and control capabilities for all your
MA 430™
sites from a
single location; each site can consist of a standalone MA 430 controller, or a MA 430
controller in a Master topology with a number of MA 410 controllers connected as
slaves. The MobileAccess Manager application is not supplied with the controller –
it is
purchased separately.
The MA NMS application is installed on a server and is accessed from any client by
connecting to the server from any Web Browser with enhanced Java VM capabilities.
MA NMS manager provides the following features and capabilities:
• Remote SNMP management from a single location
• Client/server management capability over a TCP/IP network with enhanced
monitoring and control capabilities
• Intuitive GUI that enables end-to-end fault sourcing from RIU to antennas. The GUI

2.1 Infrastructure Preparation
This following installation rules are based on the assumption that site survey and installation
planning (
including power requirements
) have been completed.
2.2 Installation Requirements
The infrastructure preparation consists of two main phases:
A. Floor Planning: Planning the distribution of the antennas on each floor to provide the
required coverage.
B. Telecom Closet Planning: Planning the layout of the devices and cables in the
telecom closet or shaft. This includes the MA 850, 802.11 Access Points, cabling and
other voice service distribution systems that are relevant to the specific installation.
2.3 Coaxial Cable Connections
2.3.1 General Cable Installation Procedures
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). Each length of cable from the risers to each antenna must be concealed above
ceiling.
The cable must be properly supported and maintained straight using tie-wraps, 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” coax cable should be 7”.
• Cable that is kinked or has a bending radius smaller than 7” 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.
Installation and Configuration Guide 7
Site Preparation
2.3.2 Fiber Optic Rules
• Use only single mode fiber for indoor applications.
• Use only 8-degree SC/APC connectors (green color).
• Use only fusion splice for connecting two fibers.
• Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB).
• 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 connections should be cleaned prior to attaching to termination points
using a dry cleaning device like the Cletop.
• Fiber connector protective caps should be installed on all non terminated fibers and
removed just before they are terminated.
• Verify the Fiber Optic connections. You may use the Optical Test Procedure
described at the end of this manual.
• Pay special attention while connecting the SC/APC connectors - you must hear the
“click” when the connection is made.
2.3.3 RF Rules
• Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for
connecting to RU and RHU ports.
• Use coax RG223, 50ohm, male-to-male N-type for connecting RF side from the Base
Unit to the BTS/RBS side.
• When using the MobileAccess™ system in an environment in which other indoor
coverage systems are installed, pay special attention to the isolation between
antennas (distance must exceed 2 meters).
• Use special attention while bending coax cables, the bending radius must not exceed
the coax specifications.
• Use any antennas suitable to the desired frequency.
• Use VSWR meter (Site Master) for checking coax cables, including the antennas.
(<2). The VSWR must be measured prior to terminating the RUs in the remote
communication rooms
• Terminate all unused RU and RIU ports with a 50 ohm load.

Site Preparation
2.5 Installation Conventions
Some of the basic installation conventions are listed below for the MA 2000 system:
• Base Units – are usually concentrated in the same location, most often in the main
communication room.
• Remote Cabinet (or 2000 Lite) – usually placed in the communication shaft or
closet of a corresponding floor so they can be easily located. Each cabinet (2000
Lite) can typically cover a floor of up to 30,000 sq ft.
• Fiber optic cable - Bundled fiber is terminated into the Base Unit in the main
communication room. This fiber is then ran vertically throughout the building
through a communication shaft or vertical riser. Individual fibers terminate on floors
into a slice box. The splice box couples the installed fiber into the remote units. Not
all fibers will terminate on a single floor. A portion of the vertically ran fibers will
terminate on each floor. Fiber cables should be purchased with enough spare fibers
terminated on each floor to support future growth.
NOTE: For example, for three remote units, six fibers are required. However to allow ,
for future upgrades, it is recommended to install additional optic fibers to be connected
to additional RUs.
• For remote power supply configuration - single source power cable – a
single cable bundle is ran from the main communication room. This bundle will
consist of a number of 18 gauge wire pairs (typical). Individual wire pairs are
terminated into the power feed of individual units.
By providing power from a single distribution point maintenance can be reduced and UPS
backup can be easily provided. The maximum distance from the source to the
termination spot is 1000 feet using 18 gauge wires. Power is typically less than 100
watts.
In many locations local codes do not require power to be run through conduit if 100
watts or less is used. Please consult the regulations within your local jurisdiction prior to
deploying remote power. When power cables require distances greater than 1000 feet
14 or 16 gauge wire may be used. 14 or 16 gauge wire offers less impedance than 18
gauge wire. While this wire is more expensive the nominal price increase far outweighs
the purchase of additional hardware.
• On each floor, the antennas are connected to the Remote Cabinet or 2000 Lite
system using coax cables.

3.1 Overview
This chapter describes how the communication room and cabinet are installed. The individual
system elements and connections are described in the Chapter 4.
3.2 Communication Room Installation
NOTE: Usually, each operator installs the equipment that supports their services in a
separa e rackt .
It is recommended to install the following MobileAccess system modules in a 19” rack in the
communication room
• RIU 3U
• BU 1U
• MobileAccess 410/430 controller 1U
• Fiber Optic patch panel and splice tray
• Power supply/supplies (MobileAccess – 3U for each unit; units from other
manufacturers may vary in size)
Verify that the rack height can support all the units to be installed, where you may also
want to consider future expansions.
12 Installation and Configuration Guide
Rack and Cabinet Installations
The following image displays the recommended physical deployment of the MobileAccess
elements in the rack in order to facilitate and simplify the cabling
connections.
r
The configuration is for a single operator. If the site is serviced by more than one operator,
each operator often installs their equipment in a separate rack.
Note that the MobileAccess 410/430 controller is at eye level to provide an easy view of
the LED indicators and LCD display and easy access to the local and remote monitoring
connections.

3.2.1 Single Building Rack Installation
This section provides an example of a single building main communication room
installation for the a 24-floor building which will distribute three services: Cellular, iDEN/PCs
(where Cellular and iDEN/PCS are supplied by the same operators).
Since there are 24 floors, then 24 RCs will be needed: one on each floor. Each RC will house
two RUs.
In addition, the following equipment will be installed in the main communication room:
• Six BUs – three to support 24 RCs for Cellular/PCS RU, and three additional BUs to
support iDEN/PCS RU
• Two MA 410/430 controllers to support the BUs: one MA 430 controller configured as
Master, and one MA 410 controller configured as slave.
NOTE: This example shows a Maste /Slave configuration, but if a network is easily
available, two MA 430 controllers may be directly connected to the network and
monitored from a single location.
• RIU – to interface to the BTS/BDA

3.2.2 Multi-Building Rack Installation
Figure 3-4 provides an example of a multi-building solution which distributes three bands
over a main site and two remote sites. Each site consists of an 8-floor building, requiring 8
RCs per building (one on each floor). Each RC will contain two dual-band RUs.
The following equipment is required in the main communication room of each building:
• Two BUs – each BU distributes a high-band and low-band signal from a dedicated
operator to eight RUs (housed in eight separate RCs – one on each floor).
• One MA 430 controller configured as Master in the Main building, and two MA 410
controllers configured as slaves in the Remote buildings.
• MA 300 Main in the main building, and MA 300 Slave in each of the remote buildings.
The MA 300 units extend the RF signal from the Main to the Remote buildings over a single
strand of fiber. Uplink and downlink signal are placed on the single fiber at 1310 and 1550
respectively.

3.3 Remote Cabinet Installation and
Connections
Mount and install the Remote Cabinet (RC) either on the wall in the communication shaft or
communication room or in a 19” rack in the
communication room
allocated to that area
(sometimes referred to as a secondary communication room).
The procedure varies slightly depending on whether the RC is an
integrated
or
ex ernal
power supply model. The following sections describe both procedures.
