MobileAccess WiMAX Indoor Coverage Solution provides a complete, cost effective, scalable
indoor coverage solution for up to two MIMO WiMAX.
The MA-WiMAX solution enables distributing signals from a WiMAX BTS located at a central
location over fiber optic connections to remote locations (different floors or areas) throughout
the building infrastructure.
The solution can be used as stand-alone - providing only WiMAX coverage via a dedicated
antenna infrastructure, or in conjunction with MA-1000 or MA-2000 MobileAccess systems –
combining WiMAX with other wireless services for distribution over a common antenna
infrastructure.
MA WiMAX system provides a truly integrated solution offering a combined services approach to
distribute WiMAX and cellular/PCS through a single antenna infrastructure while maintaining a
reliable application independent environment.
The following block diagram illustrates the stand-alone MA WiMAX solution elements: the MA
WiMAX front end equipment is installed near the WiMAX BTS. In the downlink, it conditions the
signal and converts it to fiber optic for transmission to each remote site over the optic fiber. At
each remote site it is reconverted to RF and distributed by two WiMAX antennas.
Each MA WiMAX element is set up and monitored through a local connection from a computer
running the MCT application.

Features and Capabilities
• Supports two WiMAX MIMO
• Scalable: Easily expands as needed to cover several million square feet
• Enterprise Value: Solution is easily integrated with other wireless applications – opportunity
to amortize deployment costs
• Reduced Barrier to Entry: Modular design enables pay-as-you-grow model – add sectors and
components as needed
• End-to-end Management: Proactive management and control maximizes uptime
• Local and remote end-to-end monitoring and control through interface to MA 410 controllers
• Monitoring at the head-end through interface to MA-RIU
1.1 System Architecture
The system is based on front-end elements that condition and convert the BTS WiMAX signal to
an optic signal for transmission over single mode fiber optics to the head-end elements, and on
head-end elements that reconvert the WiMAX optic signal to RF and distribute it over the
antenna infrastructure at that location. In addition, Controllers located at the front-end provide
end-to-end remote control and management.
The MA WiMAX system can be converged with another MA mobile service indoor distribution
systems (such as MA2000, MA1000, etc.), where the systems run in parallel and share some of
the same front-end elements and the antenna infrastructure.
The MA WiMAX system front end elements are:
• MA WiMAX RIU – conditions the RF signal from the BTS to the level required by the Base
Unit. Each RIU supports two WiMAX channels (for MIMO) and two base 4 units (for 8 remote
units). See section 2.1.1 for unit description.
• MA Multi-service Base Unit – converts the WIMAX channels to optic signal for transmission
over one set of optical fibers. See section 2.1.2 for unit description.
• MA 410 controller – provides management and control functions to all system elements. The
Controller is directly connected to the RIU modules and to the BUs. See section 2.1.3 for unit
description.
Note: The RIU, Base Units and Controller are located at the head-end (i.e. communication room).
The WiMAX systems remote location elements are:
• WiMAX RHU – located at each remote location, IDF or telecom closet. Performs the optic to
RF conversion of the WiMAX signals and provides the interface (power and communications)
to the remote antenna unit (RU) via which the signals are distributed. See section 2.2.1 for
unit description.
• Remote Antenna Unit (RA) – provides final preparation of the WIMAX signals for distribution
via the ceiling antenna(s). The RU has three antenna ports to support 2 MIMOs and one
passive cellular antenna. See section 2.2.2 for unit description.

1.2 WiMAX Standalone Solution – Basic System
Operation
Figure 1-2 shows the architecture of a stand-alone MA WiMAX system. The WiMAX system
receives the services from the operator’s BTS converts them to an optical signal and runs them
over optic fiber to each remote location. There, the WiMAX RHU reconverts the services to RF
and distributes them to WiMAX antennas via the MA Remote Antenna Unit. The latter provides
remote control and management to the passive WiMAX antennas.

WiMAX System User Manual
MobileAccess WiMAX System User’s Guide 14
1.3 WiMAX Overlay Solution
Overlay with Cellular and WiMAX.
Figure-
1-3
shows the architecture of an installation supporting the indoor distribution of WiMAX,
together with cellular services over a common coax and antenna infrastructure.
The figure shows two systems running in parallel: Cellular system along side of a WiMAX system
(at the bottom). Both systems received the services from the operator’s BTS or BDA, convert
them to an optical signal and run them over optic fiber to each remote location. There, the
cellular RHU reconverts the cellular services to RF and the WiMAX RHU converges the cellular
and WiMAX services and distributes them to the WiMAX and cellular antennas via the MA
Remote Antenna Unit. The latter provides remote control and management to the passive
WiMAX and cellular antennas.

1.4 Converged Cellular-WiMAX system
The WRIU can support a cellular RIU. The cellular RIU is connected to the WRIU threw a
dedicated port. The cellular RIU can support up to 3 BTSC. The WRIU combines the cellular
traffic with the WiMAX signals and transmits them together to the BU. At the end, a passive
antenna can be connected to the RA in addition to the MIMO1 and MIMO2 antennas.

1.5 Commissioning and Control
The current version of the system is configured and managed via a local connection from a
computer running the MA MCT application. See

4.1 Overview
The commissioning procedure for WiMAX systems consists of four basic phases:
1. General Checks – verifying that all units are operational and that the infrastructure is in
tact allowing signals to be transferred between the units.
2. Performing Continuous Wave downlink gain adjustments
3. Performing a Continuous Wave test under each antenna.
4. Commissioning carriers onto the system
Each of the above phases will be detailed in the following sections.
4.2 Requirements
Testing Equipment/Documentation Required
• Signal Generator for generating 2695 MHz
• Optical Power meter 1310nm & 1550nm
• MobileAccess Documentation
• MobileAccess Data Sheets
4.3 General Checks
The procedures described in this section are used to verify that all units are operational and that
the infrastructure is intact allowing signals to be transferred between the units. Please read the
entire document before you attempt to commission a MobileAccess system
A summary of all the general checks is given below. Each step is detailed in the following
sections.
1. Verify connections.
2. Set up MCT monitoring - from the MCT application, logon to the MA410.
3. Verify the controller clock settings – this enables correctly time stamping any generated
events
WiMAX System User Manual
MobileAccess WiMAX System User’s Guide 34
4. Verify end-to-end link in the topology tree by ensuring that all RHUs all visible.
5. Set the base line – ensuring that disconnected units are also displayed.
6. Check each RHU DL optical level from the Base Unit and verify the band configuration for the
RHU.
7. Check Base Unit Optical Levels from the RHUs.
8. Name each BU, each RHU and each RIU.
4.3.1 Verify Connections
1. Check all RF, Fiber and Power connections before powering-up the units.
2. Apply power (first to the Bus and then to the RHUs) and verify all power and optical link
lights are on for the RIU, 410, RHUs and Base Units. Swap between the connections
between the To and From fiber ports if the link LED does not light.
3. Remove the fiber connected to each “From” port on the Base Unit(s) and use an Optical
Meter to measure the signal.
Expected level: >0dBm @ 1310nm.
Corrective action: If the signal is not at the expected level, clean all connectors, if problem
persists carry out a full sweep of the fiber connection using an Optical Time Domain
Reflectometer (OTDR)
WiMAX System User Manual
MobileAccess WiMAX System User’s Guide 35
4.3.2 Set Up MCT Monitoring
To set up monitoring via MCT
1. Install the MCT application (from the CD provided with your kit) on the computer from which
you will be performing the commissioning procedure.
2. Connect to the RS232 port on the front of the MA Controller 410(as illustrated below).
3. Launch the MCT and Log in using Field Eng user and eng password.
Note: You may have to use a USB cable with a serial connection if your computer lacks a DB9
serial port.
4.3.3 Verify the Controller Clock Settings
Verify the Controller date and time settings are correct as follows:
• In the Network Topology, double-click on the controller.
• In the invoked dialog, choose the General tab.
• In the Time and Date area, verify the correct time (24 hour clock) and date are
defined. The date is represented as DD/MM/YYYY.
• To modify, click on Modify and make the required changes in the invoked dialog.

4.3.4 Verify End-to-End Link in Topology Tree
Verify end-to-end link connection by ensuring that each RHU is displayed in the Network
Topology tree.
To view the RHUs in the Topology Tree
The RHUs are listed under the corresponding Base Unit, referred to as OPTM in the tree. (An
OPTM is a four port module of a BU – i.e. an 8-port BU is listed as two OPTMs). Each RHU is
listed according to the BU (OPTM) port to which it is connected. Each Add-on is listed under its
host RHU.
IMPORTANT NOTE! If the RHUs are not all visible, reset or power cycle the Base Units to
which it is connected. If this does not resolve the problem, troubleshoot the optical links for dirt
or other problems.
WiMAX System User Manual
MobileAccess WiMAX System User’s Guide 37
4.3.5 Set the Base Line
Once all equipment on site is visible in MCT, set the base line. This sets
all
the MobileAccess
devices currently displayed in the Network Topology pane as a reference and will continue
displaying them (in red versus gray) if communication is lost.
Note: Mobile Access devices that are not displayed in the tree when the Base Line button is clicked will
disappear if communication with them is lost.
To set the baseline for each controller
1. Double-click on the Master Controller in the Network Topology tree and in the invoked
dialog, click the MobileAccess tab.
2. In the MobileAccess tab, click the Set Base Line button.
4.3.6 Verify End Units Optical Signal and Service Band
To Verify End Units Optical Signal and Service Band
1. Select each RHU and in the invoked dialog, click the General tab.
2. Verify the downlink optical signal level on each RHU by reading the signal value under
Optical Link Level.
Greater
than 100 is very good. If it is less than 80, determine why (dirty fiber, too many
splices/patch panels). The system can compensate for optical levels down to about 70. If it
is that low, clean the fiber using CLETOP cleaners as appropriate for male connectors and
female receptors.
WiMAX System User Manual
MobileAccess WiMAX System User’s Guide 38
4.3.7 Name the BUs, RHUs and RIUs

Network Topology tree display differs from the NMS Network Topology Tree display.
The MCT Network Topology tree shows a
single
connected controller to which the session was
opened, and the hosted devices – RIUs, Base Units, RHU. The view displays both connected and
disconnected network devices in the appropriate hierarchy and colors corresponding to their
status.
The MCT Network Topology tree includes problem sourcing features such as:
• Color indication corresponding to the elements status
• Real-time updates of device status
• Upward propagated element status colors
• Arrows indicators leading towards the element that is the source of the problem
The devices are displayed as follows:
• CNTRL – controller
• BDAC/WRIU – RIU displayed according to BDAC or WRIU modules, where the suffix ‘L’
(i.e. BDACL) stands for RIU Lite.
• OPTM-1/OPTM-2 - Base Unit displayed according to 4-port modules, where each 4-port
module is referred to as OPTM. Each OPTM is displayed along with the Controller port to
which it is connected.
• RHU – Remote Hub Units. Each RHU is displayed under the OPTM to which it is physically
connected, along with the OPTM port to which it is connected.

5.7 Configuring MobileAccess Devices
Once the controller has been configured to operate with MobileAccess devices, these type of
devices are automatically identified by the controller and are displayed in the Network Topology.
Additional device parameters may then be configured according to the installation and site
requirements. For example, if your system includes an RIU, each BU must be configured to
receive its RF signal source via an RIU (since by default it is configured to interface with passive
interface).
The procedures are performed from the configuration dialog of each device. The dialog is
invoked by double-clicking on the element in the Network Topology or in the Device View
pane.
5.7.1 Configuring for a MobileAccess Device Hosting
In this mode, the controller activates an Auto detection mechanism that constantly monitors its
RS485 rear panel ports for BUs and RIU devices.
RHUs and add-ons are detected in a similar manner by their host OPTM (BU element)
every time
the BU is powered-up or reset from the MCT
and added to the Network Topology.
Note: Newly added RHUs or add-on’s will be detected by the OPTM only after the OPTM has
been reset. The reset can be software executed through the OPTM configuration dialog.
Zoom-in of auxiliary ports display. Defined ports are
displayed in Green (OK) or Red (fault detected).
Undefined ports are displayed in grey (not relevant).
