2 System Overview
MicroMAX is a highly upgradeable Micro-cell base station, based on the Sequans System On a
Chip (SOC), with a pole/roof (wall) mounted radio system and antennae. This high performance
chip can support up to 28 + 28 MHz channels (full duplex) forms part of the AIRSPAN WIMAX
portfolio of WiMAX network infrastructure equipment. It is compatible with the Airspan EasyST
and ProST subscriber terminals and other manufacturer's CPEs that are fully WiMAX compliant.
The MicroMAX BSR is an outdoor radio that is mounted outside on a pole or wall. The BSR
provides a wireless link with subscribers and interfaces with the provider's backbone. The
MicroMAX BSR is available in two models. These models differ by antenna design (providing
integral flat-panel antennas, or an N-type port for attaching third-party external antennas).
MicroMAX BSR is available in numerous frequency bands, operating in FDD and TDD modes in
numerous channels see: MicroMAX Frequency Ranges.
The BSR connects to the indoor Ethernet switch by a CAT-5e cable, which carries the Ethernet
signal, and DC power. For a MicroMAX Base Station consisting of multiple BSRs, there are two
(2) options. The BSRs can be connected to individual Subscriber Data Adapters (SDA-4S) or to
Base Station Distribution Units (BSDU). For a Base Station consisting of a single BSR, the BSR
typically connects to a single Subscriber Data Adapter (SDA-4S or SDA-4SDC).
MicroMAX BSR provides a low cost, high-performance point-to multipoint packet-based
Broadband Wireless Access (BWA) solution. MicroMAX BSR Provides wireless connectivity
designed to deliver high-speed data, voice over IP (VoIP) and multimedia services to residential,
SOHO (Small Office/Home Office), and SME (Small to Medium Enterprises).
The MicroMAX is an encased outdoor radio providing access to the MicroMAX's communication
ports on its bottom panel. The MicroMAX's back panel provides holes for mounting.
MicroMAX BSR interfaces with the service provider's backbone through either:
¾ The SDA-4S Type II or the SDA-4SDC (referred henceforth as SDA-4S) integrated LAN
switches.
• SDA-4S Type II: integrated LAN switch, providing power and four 10/100BaseT ports
for interfacing with the subscriber’s network
• SDA-4SDC Type II: integrated LAN switch, providing power and four 10/100BaseT
interfaces and especially designed for implementation where available power supply
is DC (10 to 52 VDC), e.g. from a solar panel. This model provides regulated –48
VDC power to the BSR.
¾ Base Station Distribution Unit (BSDU) - provides an interface between multiple BSRs
and the service provider's backbone.
MicroMAX can be managed by an SNMP-based network management system (Netspan) using
standard and proprietary MIBs. In addition, external third-party management systems such as HP
OpenView can also manage the MicroMAX using these MIBs. Basic management can be
performed using any standard Web browser.
Note: For management refer to MicroMAX Web Management documentation.

3.3 Radio Site Planning
Proper site selection and planning before installing your MicroMAX will ensure a successful
deployment of your AIRSPAN WIMAX system. A summary of the main site planning
considerations is provided below:
¾ Minimum obstructions (e.g. buildings) in the radio path between base station and the
subscriber terminals.
¾ Mount radio as high as possible to avoid obstructions in the wireless path.
¾ Check possibility of future obstructions such as plans to erect buildings and trees that
may grow tall enough to obstruct the wireless path.
¾ Align radio for maximizing received signal strength (RSS).
¾ Consider nearby sources of interference that could degrade performance of radio.
¾ Mount radio as far from sources of interference as possible.
¾ Ensure base station and subscriber terminals (i.e ProST/EasyST) are within maximum
coverage range of reception.
¾ Maximum standard CAT-5e cable length connecting the MicroMAX to the indoor SDA-4S
or BSDU is 100 meters.
¾ Ensure that you have sufficient wiring conduit and cable ties to channel and protect the
CAT-5e cable connecting the outdoor MicroMAX to the indoor SDA-4S.
3.3.1 Radio Antenna Alignment
ProST
Once the subscriber unit (i.e. ProST) is installed and aimed in the general direction of the BSR, it
is recommended to measure the received signal strength (RSS) to determine the signal strength
received from the BSR, and to precisely align the ProST for maximum signal strength.
You need to orientate (up/down, left/right) the ProST until the maximum RSSI levels are achieved,
and then secure the ProST.
EasyST
Once the subscriber unit (i.e. EasyST) is installed and aimed in the general direction of the BSR,
simply move the EasyST to the position that gives optimal reception.

7 GPS Description
This section provides a description of the Global Positioning System (GPS).
Note: Even if there is a single isolated BS with multiple sectors the GPS is
required.
The third-party GPS antenna is a rugged, self-contained GPS receiver and antenna that receives
a universal GPS satellite clock signal. The GPS connects to the BSDU. The GPS synchronizes
(based on frequency hopping) multiple Base Stations, ensuring that the entire Airspan WiMAX
network operates with the same clock based on a universal satellite clock signal. This is crucial in
eliminating radio frequency ghosting effects.

9 Mounting the Base Station Radio (BSR)
The MicroMAX BSR can be pole-mounted or wall-mounted (optional). Pole mounting allows the
BSR to be easily adjusted in the horizontal (azimuth) and vertical (elevation) planes for antenna
alignment.
For either mounting method, the MicroMAX provides mounting holes (displayed in the figure
below), molded into its back panel for attaching the mounting brackets.
Note: The BSR fully complies with IP Code - IPX6 for product enclosure
protection.
Warning: The BSR device is an outdoor radio unit, and therefore, must only
be mounted outside.

13 Cabling the BSR
Network cabling at the Base Station depends on the devices implemented to provide the BSR
with connectivity to the provider's backhaul and power source. These devices can be one of the
following:
¾ SDA: AC/DC powered and consisting of a single BSR
¾ BSDU: AC/DC powered and consisting of multiple BSRs
Note: SFTP (Shielded Foiled Twisted Pair) CAT-5e outdoor cable is
recommended.
Note: If FM interference is discovered during installation, install a Ferrite
suppressor on the CAT-5e cable, near BSR. See Lightning and Surge
Protection. Refer to Commissioning Guide (Troubleshooting section) for
further instructions.
13.1 Connecting the BSR to the SDA-4S
The SDA-4S provides -48 VDC power to the BSR as well as the Fast Ethernet interface between
the BSR and the provider's backhaul network. The outdoor Base Station Radio and modem are
powered over a CAT-5e cable by the SDA-4S Type II IDU (or the SDA-4SDC) in the minimum
configuration. For larger configurations N* SDA-4Ss and N* BSRs are required or connection to
BSDU(s).
Figure 42 - BSR front panel
The BSR interfaces with the subscriber's Ethernet network through the SDA-4S. To connect the
BSR to the SDA-4S, you need to connect the BSR's 15-pin D-type port to the SDA-4S's 15-pin D-
type port using CAT-5e cable.
The cable setup for MicroMAX-to-SDA-4S connectivity is as follows:
¾ Cable: Straight-through CAT-5e Ethernet cable
¾ Connectors:
• MicroMAX: DB15-to-RJ45 outdoor adapter (black color)
• SDA-4S: DB15-to-RJ45 indoor adapter (for connecting to DATA&PWR&SYNC D-type
connector)
• CAT-5e cable with 8-pin RJ-45 male connectors on either end
¾ Connector pinouts:
MicroMAX Hardware Installation User Guide
Page 60 Commercial in Confidence UWB-D00068 Rev J
Figure 43 - Pinouts
Note: The wire color-coding described in the table is Airspan's standard for
wire color-coding. However, if you implement your company's wire color-
coding scheme, ensure that the wires are paired and twisted according to pin
functions listed in the table above (e.g. Rx+ with Rx-).
Note: The maximum CAT-5e cable length for ODU/IDU connectivity is 100
meters.
To connect the BSR to the SDA-4S:
1. Connect the 15-pin D-type male connector, at one end of the CAT-5e cable, to the BSR's 15-
pin D-type port labeled DATA&PWR&SYNC.
2. Connect the 15-pin D-type male connector, at the other end of the CAT-5e cable, to the
SDA-4S's 15-pin D-type port.
13.2 SDA-4S Type II
The SDA-4S Type II (or the SDA-4SDC) provides one to four RJ-45 (100BaseT) ports for
interfacing with the subscriber's LAN network.
The ports of the SDA-4S model support Auto Negotiation, allowing automatic configuration for the
highest possible speed link (10BaseT or 100BaseT), and Full Duplex or Half Duplex mode. In
other words, the speed of the connected device (e.g. PC) determines the speed at which packets
are transmitted through the specific port. For example, if the device to which the port is connected
is running at 100 Mbps, the port connection will transmit packets at 100 Mbps. Conversely, if the
device to which the port is connected is running at 10 Mbps, the port connection will transmit
packets at 10 Mbps
In addition, the SDA-4S ports support MDI/MDI-X automatic crossover, allowing connection to
straight-through or crossover CAT-5e cables. Therefore, these ports can be connected to either a
hub (i.e. using crossover cables) or a PC (i.e. using straight-through cables).
The cable setup for SDA-4S LAN connectivity is as follows:
¾ Cable: Straight-through (e.g. when connecting to PC) or crossover (i.e. when connecting
to a hub) CAT-5e Ethernet cable
¾ Connectors: 8-pin RJ-45 at both ends
¾ Connector pinouts:
• Straight-through cable (e.g. connecting to a PC)

Recommended good practices:

¾ Proper Bonding
¾ Proper Grounding
17.1 Lightning Protection
This is to describe the known mitigation defenses in general terms for application to
telecommunications facilities. A hierarchy of recognized application methods should be applied
according to site realities. This matrix is depicted below:
Table 28 - Application matrix
Exterior locationInterior LocationPeople SafetyStructure Safety
Air Terminals Yes No No Yes
Down Conductors Yes Yes No Yes
Bonding Yes Yes Yes Yes
Grounding Yes Yes Yes Yes
Surge Protection Yes Yes Yes Yes
17.1.1 Air Terminals
Lightning usually terminates on grounded objects sticking up in the air. This part of a lightning
protection system (LPS) is based upon the principles of Path of Least Impedance. On telecom
towers, ordinary sacrificial rods can protect sensitive antennae. In the main, the tower is the air
terminal. the height (“H”) of the Air Terminal tip above the highest element on the tower or pole,
typically the antenna, must be at least twice the distance (“2 x d”) between the outer surface of
the antenna and the tower or pole. This will ensure a "protection cone" of 45º around the tower or
pole. In areas of high lightning activity, the length (“H”) should be increased to up to 5 times the
distance. The Down Conductor must be installed straight and vertically in order to provide the
shortest and most direct path to earth. The formation of bends must be avoided.
We recommend that the Down-Conductor be at least 50 mm2 or AWG 0 in all cases.
MicroMAX Hardware Installation User Guide
Page 80 Commercial in Confidence UWB-D00068 Rev J
Figure 71 - Air Terminal
Figure 72 - Termination and Tower
17.1.2 Grounding
Low-resistance grounding provides an efficient destination for the "lightning." If the site soils are
composed of sand or rock, they are resistive, not conductive. If the surrounding soils are clays or
dirt with moisture present, they likely are conductive. "Good Grounds" are achieved by volumetric
efficiencies. We recommend buried bare 4/0 copper wire – the so-called ring electrode or ring.
The grounding of the Down Conductor to earth must be of ground resistance no higher than 5 Ω.
This is achieved by using Earth Terminations and wherever possible, grounding to the steel re-
enforcement bars of the concrete base of the tower. This constitutes a part of the safety network
adapted to the electricity laws of the country, the terrain conditions, and the accepted and relevant
standards for the country.
MicroMAX Hardware Installation User Guide
Page 81 Commercial in Confidence UWB-D00068 Rev J
Note: The Grounding system must be maintained and checked periodically in
accordance with local regulations.
The Interconnecting cables shall be acceptable for external use and shall be
rated for proper application with respect to voltage, current, anticipated
temperature, flammability, and mechanical serviceability.
Hazardous network voltages are present in LAN ports regardless of whether
power to the unit is ON or OFF. To avoid electric shock , use caution when
near LAN ports. When detaching the cables, detach the end away from the
device first.
Do not work on the system or connect or disconnect cables during period of
lightning activity.
17.1.3 Surge Suppression
Surge suppression devices (LPS’s aka TVSS) all function either by absorbing the transient as
heat or forcing the transient to ground (or some combination thereof). Data line building entry
points for critical electronic equipment. Included here is Catting 5 lines, and twin lead and other
copper wire circuits.
The Lightning Protection architecture is considered, as follows:
¾ Subscriber Indoor Units connected to outdoor antennas. System, where Indoor/Outdoor
connections are via shielded CAT-5e cables that carry the baseband signals and a DC
supply voltage.
¾ The Lightning Protection System comprises grounding methods and Transient
suppression techniques (TVS).
Airspan products contain embedded Lightning Protectors at all their input ports. If additional
protection is required, for example, in high lightning activity areas, external Lightning Protectors
should be installed at strategic points at the site.
The CAT-5e shielded outdoor cable consists of twisted pair wires for Ethernet data, pair of wires
for the DC supply and pair of wires for sync. The Cable connects to the indoor unit via a grounded
Lightning Protection Box. The Lightning Protection Box is connected to an Earth Termination via a
Down-Conductor.

17.2 Cable Preparation (for grounding)
The CAT-5e SFTP cable is supplied unassembled. Therefore, you need to crimp the drain wire to
the ring terminal and paired wires to the connector's contact pins.
Required:
¾ CAT-5e SFTP cable
¾ Ring terminal and red insulation boot
¾ Crimping tool
To crimp the CAT-5e SFTP “drain” wire to the ring terminal:
1. Carefully strip the insulation from the SFTP cable (5 – 10cm).
Caution: Do not damage the insulation of the inner twisted pair wires.
2. Peel back the foil from around the wires.
3. Isolate the “drain” (ground) wire.
4. Crimp the ring terminal to the drain wire. Insert the wire into the ring terminal’s barrel, and
then, with a standard crimping tool crimp the barrel tightly onto the wire. Fold back the drain
wire with the ring terminal attached.
5. Strip the ends of the paired wires according to the connector.
6. Connect ground wire (with extension if required) to the tower.
The figures and connections are displayed below:
MicroMAX Hardware Installation User Guide

Figure 76 - Ring terminal
Figure 77 – CAT-5e SFTP cable with ring terminal
Figure 78 - Complete assembly with Ferrite (optional)
17.3 FM Interference & ESD Protection Recommendations
When FM Interference is a factor:
¾ Ferrite suppressor (displayed in figure above) on the CAT-5e cable, near BSR
¾ Loop the CAT-5e cable on the BSR end
When ESD is an issue:
¾ Verify that the CAT-5e SFTP cable properly grounded at both ends
17.4 Connecting Lightning and Surge Protector
The optional third-party lightning and surge protector (Polyphaser) is implemented in the following
deployment scenarios:
¾ ODU-to-IDU cable length of 40 meters or more (mandatory to use surge protector)
MicroMAX Hardware Installation User Guide
Page 86 Commercial in Confidence UWB-D00068 Rev J
¾ Deployment of MicroMAX in geographical areas that frequently experience severe
lightning storms
The lightning and surge protector protects the ODU-to-IDU CAT-5e cable's six or eight
(depending on configuration) (for GPS synchronization all 8 CAT-5e wires are used) used wires
(two -48 VDC wires and four Ethernet Tx and Rx wires) from any electrical surges due to lighting
strikes.
The protector is installed outdoors on the CA-5e cable that connects between the MicroMAX and
the SDA-4S Type II (ODU). In other words, two CAT-5e cables are required for the following
connections:
¾ MicroMAX-to-protector connection
¾ Protector-to-IDU connection
Caution: Do not install the lightning and surge protector during adverse
weather conditions when the threat of lightning strike is possible.
Note: The protector unit must be grounded to a low-impedance (low R and
low L) ground system to operate properly.
Note: For pricing and ordering of the Polyphaser lightning and surge
protector, contact your Airspan representative.
To install the lightning protector:
1. Connect the protector in the direction according to the labels. The end labeled SURGE
accepts the cable from the MicroMAX; the end labeled PROTECTED accepts the cable from
the SDA-4S, or BSDU.
2. Feed the CAT-5e cable through the grommet (for each side). If the RJ-45 connector is
already crimped to the other end, ensure that you have fed the cable through the gland nut
beforehand. The gland nut secures the cable to the grommet.
3. Strip about 0.25" (6.35 mm) of the cable sheath and expose about 0.03" (0.8 mm) of the
strands/wires.
4. Secure the wires to the protector's terminal block using the two spot ties. Each side of the
data and DC assembly has + or – markings to ensure lines entering (surge side) match lines
exiting (protected side).
Note: Polyphaser should be installed close to the units but only externally.

18 Connecting Third-Party External Antennas
This section describes the procedures for connecting third-party external radio and Global
Positioning System (GPS) antennas to the BSR and BSDU, respectively. The implementation of
these antennas depends on the BSR model (with respect to radio antennas) and the need for
synchronization of the system (with respect to GPS antennas).
The MicroMAX BSR model without a built-in antenna provides an N-type port for connecting a
third-party external antenna. The addition of an external antenna allows greater RF sector
coverage than the standard MicroMAX BSR built-in antenna model.
Caution: Before connecting the external antenna, ensure that the MicroMAX
is not connected to the power source.
Caution: Before powering on the MicroMAX, ensure that some type of
equipment such as an antenna or an RF attenuator is connected to the N-
type receptacle. This eliminates the risk of irreversibly damaging the
MicroMAX device.
Caution: It is the responsibility of the person installing the MicroMAX to
ensure that only those antennas certified with the product are used. The use
of any antenna other than those certified with the product is expressly
forbidden.
Caution: The external antenna must not be co-located or operating in

18.1 Connecting GPS Antenna to BSDU
Caution: To avoid electrical or fire hazard, ensure that the connection to the
GPS is made prior to connecting the BSDU to the power supply.
Caution: A primary lightning protection device must be provided by the
operator/customer as part of an extra-building installation to ensure transient
voltage levels of less than 600 V maximum.
Caution: Changes or modifications to this equipment not expressly approved
by Airspan Networks Inc. could result in violation of Part 15 of the FCC rules.
Caution: This is a Class B product. In a domestic environment this product
may cause radio interference in which case the user may be required to take
adequate measures to correct the interference.
18.1.1 Connecting the GPS
The GPS antenna connects to the BSDU's 15-pin D-type port, labeled GPS, located on the
BSDU's rear panel, as shown below. The connection to the GPS is made through a 12-pin RS-
422 serial interface port that provides both communication and power interfaces.

Figure 88 - BSDU rear panel GPS port
Caution: To avoid electrical or fire hazard, ensure that the connection to the
GPS is made prior to connecting the BSDU to the power supply.
The GPS-to-BSDU cable setup is as follows:
¾ Cable: 12-pin conductor cable for RS-422 serial interface (multipair overall shielded -- 22
AWG) of 5, 15, or 30 meters in length depending on customer requirements (100 meter
maximum length)
¾ Connectors:
• GPS side: RS-422 weathertight 12-pin plug (Deutsch MMP26C-2212S1)
• BSDU side: 15-pin D-type male
• Connector pinouts: The GPS connector receptacle contains 12 male contacts, as
displayed below:

To connect the GPS antenna to the BSDU:
1. Connect the 12-pin female connector, at one end of the cable, to the 12-pin receptacle
located on the underside of the GPS.
2. Connect the 15-pin D-type male connector, at the other end of the cable, to the 15-pin D-
type port labeled GPS located on the rear panel of the BSDU.
Figure 90 - GPS-to-BSDU cable connection
Note:
• When installing the cable, secure the cable to the mounting
pole or bracket with a cable tie to hold the weight of the cable
(i.e. cable strain relief).
• A loop should be left in the dressed cable for maintenance
purposes and to prevent the cable weight being taken
directly on the connector itself.
• Ensure that the connector is waterproof.
18.1.2 GPS Alignment
Many GPS reception problems can be reduced, to some degree, by careful antenna site
selection.
¾ Place the GPS so that unobstructed line-of-sight reception is possible from horizon to
horizon and at all bearings and elevation angles from the antenna. This is the ideal
situation, which may not be possible under actual operating conditions.
¾ Try to place the GPS as far as possible from reflective objects, especially reflective
objects that are above its radiation pattern horizon. Close-in reflections cause strong
multipath signals.
¾ Care should also be taken to avoid coiling the GPS cable around the mounting base and
pinching the cable in windows or doors.
