Safety
WARNING! To comply with FCC RF exposure compliance requirements, antennas used for this product
must be fixed mounted on indoor permanent structures, providing a separation distance of at least
20 cm from all persons during normal operation.
1. Each individual antenna used for this transmitter must be installed to
provide a minimum separation distance of 20 cm or more from all persons
and must not be co-located with any other antenna for meeting RF
exposure requirements.
2. The design of the antenna installation needs to be implemented in such a
way so as to ensure RF radiation safety levels and non-environmental
pollution during operation.
Compliance with RF safety requirements:
•MobileAccess™ products have no inherent significant RF radiation.
•The RF level on the downlink is very low at the downlink ports. Therefore, there is no
dangerous RF radiation when the antenna is not connected.

1.1 About MobileAccess MA 850A1
Figure 1-1. MobileAccess 850
The MA-850 Wi-Fi Module enables 802.11b/g and 802.11a Wi-Fi signals to be combined with
other wireless services for simultaneous distribution over the MobileAccess Universal Wireless
Network.
The MA-850 can be deployed in a stand-alone mode for Wi-Fi only environments, or it can be
connected to other MobileAccess elements (MA-1000/2000) to deliver Wi-Fi along with other
wireless services including cellular/PCS, public safety, and WMTS.
Unlike traditional Wi-Fi deployments, where 802.11 Access Points (APs) are installed on ceilings
and walls throughout the facility, the MA-850 enables organizations to cluster their 802.11 APs
together in secure telecom closets.
With the clustering approach, IT managers can more easily access APs, which ultimately reduces
the operational costs of managing the Wi-Fi network and minimizes disruption within the facility.

About MobileAccess MA 850A1
MA 850A1A1 Installation and Configuration Guide 2
1.1.1 MA 850A1 Features and Capabilities
•Multi-use infrastructure:
The same cables and antennas used for Wi-Fi can be used to support the simultaneous
extension and distribution of other wireless voice and data services, as follows:
oData services from four 802.11b/g APs and 802.11a APs
oMobile services from MobileAccess 1000/2000, ModuLite or Litenna remote units
•Simple installation and maintenance:
oAll active elements are in the telecom shaft or closet
oAll data and voice services distributed via a common coax cabling and broadband
antennas
oAP Clustering - 802.11 access points (APs) connect to the MA-850 in telecom closets
•Management:
oRobust system management - Familiar SNMP-based management provides proactive
visibility and control of the MA-850 based Wi-Fi infrastructure.
oManagement through local RS232 connection and remote WEB management
•WI-Fi applications transparency - The MA-850 uses discrete, passive antennas to
radiate 802.11 signals, providing a coverage architecture that replicates the behaviors
necessary to transparently support advanced AP features and location-sensitive Wi-Fi
applications.
•High-power - With integral constant gain amplifiers combined with its low-loss
architecture, the MA-850 offers scalable support for demanding applications such as wireless
VoIP and 802.11a.

Unit Architecture
MA 850A1A1 Installation and Configuration Guide 3
1.2 Unit Architecture
MA 850A1 consists of the following main
functional
modules:
•Interface: Provides interface to the 802.11b/g AP ports.
•Gain control mechanism: Gain control to adjust 802.11b/g signals to specific site
•Combining and separating mechanism: On the downlink, combines the amplified
802.11b/g signals with the 802.11a AP signals and those of mobile services. On the
uplink, separates the signals and routes them to the corresponding ports.
•Monitoring and control: Support for WEB monitoring, SNMP MIBs displayed via a
standard Web browser and local RS232 and service options.
Figure 1-2. MobileAccess 850 Functional Block Diagram
NOTE: If the MobileAccess 850 is operated without cellular service, it is required to connect
50Ωtermination points to each of the remote connectors in the unit. A 50 Ωtermination is
also required on each unused AP port.
1.3 Installation Configurations
The MA 850A1 can be installed as a standalone unit or integrated with MA 1000/2000 systems
and its signals converged with the mobile services to be distributed through the MA 850A1
antenna connections.
MA 850A1 can be installed in the following configurations:
•Standalone – to provide coverage only for 802.11a/b/g services
•Add-on to a MobileAccess 1000 series RHU (with and without MA 1200 add-on)
•Add-on to MobileAccess 2000 system
NOTE: In all installation types, all the signals are converged via the MA 850A1 and distributed
via the antennas connected to the MA 850A1 antenna ports.

Installation Configurations
MA 850A1A1 Installation and Configuration Guide 4
1.3.1 Standalone
The standalone installation configuration provides coverage for 802.11a/b/g services only and
distributes the signals over the antennas.
Figure 1-3. MA 850A1 Standalone Installation Configuration
1.3.2 Add-On to MA 1000 RHU
The MA 850A1 can be installed as an add-on unit to a MA 1000 RHU. In this type of installation,
the MA 1000 RHU services are routed to the MA 850A1 inputs where they are integrated with
the MA 850A1 Wi-Fi data services and, through the MA 850A1 antenna connections, distributed
through the same coax broadband antenna infrastructure. The following figure shows the
architecture.
Figure 1-4 MA 850A1 as Add-On to MA 1000 System
1.3.3 Add-on to MA 2000 System
The MA 850A1 can be installed as an (external) add-on unit to the MA 2000 system. In this type
of installation, the combined MA 2000 services are routed to the MA 850A1 inputs where they
are integrated with the MA 850A1 Wi-Fi data services and, through the MA 850A1 antenna
connections, distributed through the same coax broadband antenna infrastructure. The
following figure shows the architecture.

Signal Distribution in the MA 850A1
MA 850A1A1 Installation and Configuration Guide 5
Figure 1-5. MA 850A1 Add-On to MA 2000 System
1.4 Signal Distribution in the MA 850A1
The MA 850A1 distributes the 802.11a/b/g signals from each AP port to the corresponding
antenna port and mobile services (where MA 1000/2000 systems are integrated with the MA
850A1), over all connected antennas. For example, the signals from an AP connected to 802.11
port-2, is routed to antenna port-2; signals from an AP connected to 802.11b/g port-4, is routed
to antenna 4, etc.
The following figure shows an 802.11a distribution example. Signals of AP connected to 802.11a
ports 2 and 4 are routed to the corresponding antenna ports (2 and 4). Areas covered by
antennas 1 and 3 do not receive 802.11a signals.
Figure 1-6. Example of 802.11a Signal Distribution
The following figure shows an 802.11b/g distribution example. Signals of AP connected to
802.11b/g ports 2 and 3 are routed to the corresponding antenna ports (2 and 3).
Figure 1-7. Example of 802.11b/g Signal Distribution

Signal Distribution in the MA 850A1
MA 850A1A1 Installation and Configuration Guide 6
The following figure shows an 802.11a/b/g distribution example. Signals of AP connected to
802.11a ports 1 and 2 are routed to the corresponding antenna ports (1 and 2). Signals of AP
connected to 802.11b/g ports 2 and 3 are routed to the corresponding antenna ports (2 and 3).
In the example, antenna-1 zone supports 802.11a services, antenna-2 zone supports 802.11b/g
services and antenna-3 zone supports 802.11a/b/g services.
Figure 1-8. Example of 802.11a/b/g Signal Distribution
The following figure shows an 802.11a/b/g and mobile distribution example. Mobile services
from 1000 RHU are distributed over all four antenna zones. In addition, antenna-1 zone supports
802.11a services, antenna-2 zone supports 802.11b/g services and antenna-3 zone supports
802.11a/b/g services.

Commissioning and Monitoring
MA 850A1A1 Installation and Configuration Guide 7
1.5 Commissioning and Monitoring
MA 850A1 AP and antenna connections can be remotely monitored by opening a WEB session to
the IP address of the unit. The unit is assigned a default IP address (labeled on its network port)
which can be remotely redefined using the procedure in section 4.2.1. No other setup procedure
is required: after the unit ports and cables are connected, the unit can be remotely accessed.
In addition, MA 850A1 provides MIBs that enables viewing traps and configuring the unit
through standard SNMP (Version 2.0) managers such as HP OpenView.
NOTE: In addition, the unit can be locally configured by MA service personnel, through a
connection from a computer running the Configuration Tool application supplied by MA.
