SYSTEM OVERVIEW
MicroMAX-SOC is a highly upgradeable Micro-cell base station, based on the Sequans System On a
Chip, 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 AS.MAX 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-SOC 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-SOC 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-SOC BSR is available in numerous ETSI frequency bands, operating in FDD and TDD
modes in numerous channels, see: MicroMAX-SOC Frequency Ranges.
The BSR connects to the indoor Ethernet hub/switch by a CAT 5e cable, which carries the Ethernet
signal, and DC power. For a MicroMAX-SOC Base Station consisting of multiple BSRs, the BSRs
connect to individual Subscriber Data Adapters (SDA-4S). For a Base Station consisting of a single
BSR, the BSR typically connects to a single Subscriber Data Adapter (SDA-4S).
MicroMAX-SOC BSR provides a low cost, high-performance point-to multipoint packet-based
Broadband Wireless Access (BWA) solution. MicroMAX-SOC 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-SOC is an encased outdoor radio providing access to the MicroMAX-SOC's
communication ports on its bottom panel. The MicroMAX-SOC's back panel provides holes for
mounting.
MicroMAX-SOC BSR interfaces with the subscriber's LAN through the SDA-4S Type II (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
MicroMAX-SOC 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-SOC using these MIBs. Basic management can be
performed using any standard Web browser.

Radio Site Planning
Proper site selection and planning before installing your MicroMAX-SOC will ensure a successful
deployment of your AS.MAX system. A summary of the main site planning considerations is
provided below:
Minimum obstructions (e.g. buildings) in the radio path between base station and the
subscriber terminals
Mount radio as high as possible to avoid obstructions in the wireless path
605-0000-742_MicroMAX-SOC_Installation_Rev_D
10
Check possibility of future obstructions such as plans to erect buildings and trees that may
grow tall enough to obstruct the wireless path
Align radio for maximizing received signal strength (RSS)
Consider nearby sources of interference that could degrade performance of radio
Mount radio as far from sources of interference as possible
Ensure base station and subscriber terminals (i.e ProST/EasyST) are within maximum
coverage range of reception
Maximum standard CAT-5e cable length connecting the MicroMAX-SOC to the indoor SDA-
4S is 100 meters
Ensure that you have sufficient wiring conduit and cable ties to channel and protect the CAT
5e cable connecting the outdoor MicroMAX-SOC to the indoor SDA-4S
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.

MOUNTING THE BASE STATION RADIO (BSR)
Mounting the MicroMAX-SOC
The MicroMAX-SOC 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-SOC 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.
Warning: Mount the MicroMAX-SOC in an orientation such that its ports (located on
the bottom panel) faces downwards. This prevents rain water from settling on the ports, and
thereby, avoiding damage to the unit such as corrosion and electrical short-circuiting.
Note: The standard BSR kit, provides pole-mounting brackets. If you want to wall-mount
the MicroMAX-SOC, contact your Airspan distributor for pricing and ordering of wall-mounting
brackets.
Pole-Mounting the BSR
Pole mounting allows the MicroMAX-SOC to be easily adjusted in the horizontal (azimuth) and
vertical (elevation) planes for antenna alignment. The BSR is mounted using the mounting holes
located on the BSR's back panel and the supplied pole-mounting brackets. The pole-mounting
bracket is designed to support the BSR on a round pole of 45 mm in diameter.
The figure below summarizes of the MicroMAX-SOC's pole-mounting procedure.
Mounting the Base Station Radio (BSR)
17
To pole mount the MicroMAX-SOC BSR:
1. Attach the mounting bracket to the MicroMAX-SOC:
a. Align the mounting bracket with the MicroMAX-SOC's mounting holes so that the mounting
bracket's side with the built-in nut is aligned with the BSR's mounting holes furthest from
the MicroMAX-SOC's bottom panel, as shown in the figure below.
b. Slide an M10-flat washer and M10-spring lock washer onto an M10-hex head screw (ensure
spring lock washer is closest to the bolt's head). From the external side, insert the M10-hex
head screw through the mounting bracket and MicroMAX-SOC's mounting holes. Fasten the
M10-hex head screw (one is provided with a built-in nut while the other requires you to
insert an M10-hex nut into the MicroMAX-SOC's mounting hole).
605-0000-742_MicroMAX-SOC_Installation_Rev_D
18
2. Attach the clamping bracket to the mounting bracket:
a. Slide an M6-spring lock washer onto an M6-hex head screw. Align the mounting bracket's
and clamping bracket's pivot holes, such that the clamping bracket is aligned to the inside
of the mounting bracket. From the external side of the mounting bracket, insert the M6-hex
head screw into the pivot holes and then fasten, but not tightly. (The clamping bracket
provides a built-in nut.)
b. Choose an elevation hole on the mounting bracket and then align it with the corresponding
hole on the clamping bracket. Slide an M6-spring lock washer onto an M6-hex head screw,
and then from the external side of the mounting bracket, insert the M6-hex head screw
through the elevation hole on the mounting bracket and into the clamping bracket's
corresponding hole. Fasten but not tightly the M6-hex head screw (the clamping bracket
provides built-in nut). The elevation hole can later be changed according to desired antenna
orientation in the elevation plane.
Mounting the Base Station Radio (BSR)
19
3. Attach the U-bolt to the pole:
a. Place one U-bolt around the pole, and then insert the U-bolt screw side through the two
corresponding holes (horizontally parallel) on the clamping bracket. Slide an M8-flat washer
and M8-spring lock washer onto each U-bolt screw side (ensure that the flat washer is
adjacent to the clamping bracket). Fasten each U-bolt side with the two M8-hex nuts.
b. Attach the second U-bolt as described above.
4. Perform final MicroMAX-SOC orientation:
a. Adjust the vertical position of the MicroMAX-SOC by choosing a final elevation hole as
described in Step 2. Lock the MicroMAX-SOC at the desired position by inserting the locking
bolt in the desired position and fastening it tightly. Fasten tightly the bolt in the pivot hole.
The figure below illustrates the angles (in degrees) of each elevation hole. As shown, the
MicroMAX-SOC pole-mounting bracket allows elevation between -18.5° and 26.3°.
605-0000-742_MicroMAX-SOC_Installation_Rev_D
20
b. Adjust the horizontal position of the MicroMAX-SOC by rotating it about the pole, and then
tightening the nuts of the U-bolts.
Note: A thread-locking compound must be used to prevent the bolts from working loose.
MicroMAX-SOC positioning is obtained in two planes by adjustment of the mounting bracket
assembly as shown below.
It is important to provide strain relief and drip loop for Cat-5 cables. Create a drip loop and strain
relief using cable tie, to tie cable to pole, as displayed in the figure below:
Mounting the Base Station Radio (BSR)
21
Wall-Mounting the BSR (Optional)
Note: The standard BSR kit provides pole-mounting brackets. If you want to wall-mount
the MicroMAX-SOC BSR contact your Airspan distributor for pricing and ordering of wall-
mounting brackets.
Note: A minimum of 3-meter separation is required between mounted MicroMAX-SOC's
and existing customer radio equipment when transmitting on different sectors (see figure
below). However, only a 1-meter separation is required between MicroMAX-SOC's when on
the same sector and transmitting to the same base station radio without requiring shielding.
The figure below illustrates the minimum separation between mounted MicroMAX-SOC's when
transmitting on different sectors:
MicroMAX-SOC wall mounting consists of two main stages:
Attaching the mounting bracket to the MicroMAX-SOC's mounting holes
Attaching the mounting bracket (already attached to the MicroMAX-SOC ) to the
wall (or pole)
To wall mount the MicroMAX-SOC:
1. Position the unassembled mounting bracket on the mounting surface (e.g. wall), and then
use a pencil to mark the position of the four mounting holes. Ensure that the distance
between the hole centers are 120 mm (height) and 60 mm (width), as displayed in the
figure below showing the MicroMAX-SOC's fixing dimensions.
605-0000-742_MicroMAX-SOC_Installation_Rev_D
22
2. Drill holes for each hole that you marked in the step above.
3. Insert wall anchors (not supplied) into each of the drilled holes.

the screws. Slide the screws into the mounting hooks, by lowering the SDA-4S onto the
screws.
Note: For safety, both mounting hooks must be utilized when mounting the unit.
Note: The SDA-4S is supplied with a 1-metre AC power lead assembly. Therefore, ensure
the unit is mounted within reachable distance to the customer's mains power outlet.
Note: The maximum cable run between SDA-4S and MicroMAX-SOC is 100 meters.
Therefore, ensure the unit is mounted within reachable distance.
26
CABLING THE BSR
Connecting the BSR to the SDA-4S
he 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 CAT5e Cable by the SDA-4S Type II IDU in the minimum configuration. For larger
configurations N* SDA-4Ss and N* BSRs are required.
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 a CAT-5e cable.
The cable setup for MicroMAX-SOC-to-SDA-4S connectivity is as follows:
Cable: Straight-through CAT 5e Ethernet cable
Connectors:
o
MicroMAX-SOC: DB15-to-RJ45 outdoor adapter
o
SDA-4S: DB15-to-RJ45 indoor adapter (for connecting to DATA&PWR&SYNC D-type
connector)
o
CAT 5e cable with 8-pin RJ-45 male connectors on either end
Connector 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
Cabling the BSR
27
wires are paired and twisted according to pin functions listed in the table above (e.g. Rx+
with Rx-).
Note: The maximum CAT 5 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.
SDA-4S Type II
Using the SDA-4S Type II
The SDA-4S Type II 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:
Cable: Straight-through (e.g. when connecting to PC) or crossover (i.e. when connecting to
a hub) CAT 5e Ethernet cable
Connectors: 8-pin RJ-45 at both ends
Connector pinouts:
o
Straight-through cable (e.g. connecting to a PC)
605-0000-742_MicroMAX-SOC_Installation_Rev_D
28
CONNECTING THE SDA-4S TO THE POWER SUPPLY
Connecting the SDA-4S Type II
The SDA-4S adapters are plugged into a standard electrical wall outlet (110/240 VAC) using an AC
power cord. The appropriate AC power cord is supplied according to the country of use
The cable setup between the SDA-4S and power outlet includes the following:
Connector: AC IEC 60320 type (female)
Plug: The appropriate plug type is supplied according to the country of use
Cable: 3x1.z0 mm, 10A / 250 VAC (maximum length is 180 cm)
To connect the SDA-4S to the AC power supply:
1. Connect the power plug female, at the end of the AC power chord, into the AC power socket
located on the left panel of the SDA-4S.
2. Plug the power plug male, at the other end of the AC power chord, into the AC power outlet
(110-240 VAC).
3. Verify that the power is received by the SDA-4S by checking that the POWER LED light is
on.
Cabling the BSR
29
4. Verify that your SDA-4S is on and receiving power by checking that the LED labeled
POWER is lit (see SDA-4S LED description).
Connecting SDA-4S to Ethernet Network
The MicroMAX-SOC typically interfaces with the subscriber's network/computer using the SDA-4S
Type II which provides four (10/100BaseT) LAN ports for interfacing with the subscriber's LAN
network.
Connecting Lightning and Surge Protector
The optional third-party lightning and surge protector (PolyPhaser) is implemented in the following
deployment scenarios:
ODU-to-IDU cable length of 40 meters or more (mandatory to use surge protector)
605-0000-742_MicroMAX-SOC_Installation_Rev_D
30
Deployment of MicroMAX-SOC in geographical areas that frequently experience severe
lightning storms
The lightning and surge protector protects the ODU-to-IDU CAT 5e cable's six 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 CAT 5e cable that connects between the MicroMAX-SOC
and the SDA-4S Type II. In other words, two CAT 5e cables are required for the following
connections:
MicroMAX-SOC-to-protector connection
Protector-to-IDU connection
Warning: 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-SOC; the end labeled PROTECTED accepts the cable
from the SDA-4S.
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).
5. Mount and ground the protector outdoors with the provided 2 x 8-32 screws according to
the fixing template illustrated below (showing distances between centers of the two
Cabling the BSR
31
mounting holes). The unit may be mounted/grounded on a nearby plate or bulkhead panel
that is bonded to an earth-ground system.
6. Attach the protector's lid by using the four M4 x 20-mm screws. Ensure that the neoprene
gasket on the lid is not loose or out of the groove.
7. Secure the CAT 5e cable to the grommet by fastening the gland nut.
The figure below illustrates the connectivity of the lightning and surge protector.

CONNECTING AN EXTERNAL ANTENNA
Connecting Third Party External Antenna
The MicroMAX-SOC 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-SOC BSR built-in antenna model.
Warning: Before connecting the external antenna, ensure that the MicroMAX-SOC is
not connected to the power source.
Warning: Before powering on the MicroMAX-SOC, 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-SOC device.
Warning: It is the responsibility of the person installing the MicroMAX-SOC 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.
Warning: The external antenna must not be co-located or operating in conjunction
with any other antenna or transmitter.
Warning: The MicroMAX-SOC and external antenna should be installed ONLY by
experienced installation professionals who are familiar with the local building and safety codes
and are licensed by the appropriate government authorities.
Note: The MicroMAX-SOC model that provides an N-type connector for attaching a third-
party external antenna does not contain an internal, built-in antenna.
The following lists the cable setup for attaching the external antenna:
Cable: RF coaxial
Connector: N-type male
To connect a third-party external antenna to the MicroMAX-SOC:
Connect the N-type male connector of the third-party antenna to the N-type receptacle
located on the MicroMAX-SOC's panel (labeled ANTENNA), as displayed below.

1.8 Lightning Protection
WARNING: The following notes are general recommendations for the system. The wireless
equipment should be installed by a qualified professional installer and must follow local and
national codes for electrical grounding and safety. Failure to meet safety requirements
and/or use of non-standard practices and procedures could result in personal injury and
damage to equipment. A direct lightning strike may cause serious damage even if these
guidelines are followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced
current from a near strike. Lightning protection and grounding practices in local and national
electrical codes serve to minimize equipment damage, service outages, and serious injury.
Reasons for lightning damage are summarized as:
- Poorly grounded tower/antenna sites that can conduct high lightning strike energy into
equipment.
- Lack of properly installed lightning protection equipment that can cause equipment failures
from lightning induced currents.
A lighting protection system provides a means by which the energy may enter earth without
passing through and damaging parts of a structure. A lightning protection system does not
prevent lightning from striking; it provides a means for controlling it and preventing damage
by providing a low resistance path for the discharge of energy to travel safely to ground.
Improperly grounded connections are also a source of noise that can cause sensitive
equipment to malfunction.
A good tower grounding system disperses most of the surge energy from a tower strike away
from the building and equipment. The remaining energy on the RF cable shield and center
conductor can be directed safely to ground by using a lightning arrestor in series with the RF
cable.
To limit the equipment damage due to a lightning strike, the following practices are
recommended for the wireless system:
- Provide direct grounding from the antenna mounting bracket, the radio and antenna and
the lightning arrestors to the same ground point at the base of the tower or a ground bus on
the building. Use the grounding screws on the antenna bracket and the radio and antenna for
terminating the ground wires.
605-0000-742_MicroMAX-SOC_Installation_Rev_D
42
- Install one RF lightning protector between the radio and antenna in series with the RF
cable.
- A lightning arrestor in series with the RF cable at the point of entry to the building.
- Install a lightning arrestor in series with the IF cable at the transceiver on the tower/mast.
- The AC wall outlet ground for the terminal must be connected to the same grounding
system as the radio and antenna lightning protectors.
