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.

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
• MA Multi-service Base Unit – converts the WIMAX channels to optic signal for transmission
over one set of optical fibers. See section
• 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
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
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
2.1.1 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.

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 ante nnas.
