6 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.

16 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. 4. Align the mounting bracket's four holes with the wall anchors, and then insert a screw (not supplied) through the mounting bracket holes into each wall anchor, and then tighten. Note: Airspan does not provide screws for attaching the mounting bracket to the wall. The screw size depends on the structure of the building to which the bracket is to be attached. When selecting screw sizes, consideration must be given to the weight of the MicroMAX-SOC and load that may be induced in windy conditions.
Mounting the Base Station Radio (BSR) 23 5. Attach the MicroMAX-SOC to the mounting bracket by performing the following: a. Slide an M10-spring lock washer and then an M10-plain washer onto each M10-hex head screw (ensure lock washer is nearest to head of screw bolt). b. Align the mounting bracket's holes with the MicroMAX-SOC's mounting holes as displayed below. (The mounting bracket side that provides a groove for inserting a nut must be aligned with the MicroMAX-SOC's mounting hole that is nearest to the MicroMAX-SOC's bottom panel.) c. From the external sides, insert the M10-hex head screws through the mounting bracket's holes and MicroMAX-SOC's mounting holes. Loosely fasten with the M10-hex nuts.
605-0000-742_MicroMAX-SOC_Installation_Rev_D 24 6. Adjust the horizontal positioning of the MicroMAX-SOC (see "Web-Based Management" for MicroMAX-SOC antenna alignment using RSS measurements), and then tighten the two M10-hex head screws with the M10 hex nuts. Note: A third-party thread-locking compound must be applied to the M10-hex head screws to prevent the bolts from working loose. Note: For wall mounting, rotation is restricted in the horizontal plane only. Installing the SDA-4S Type II The SDA-4S Type II is mounted vertically on a wall. Wall Mounting Wall mounting is made possible by the existence of two mounting hooks molded into the SDA-4S's bottom panel, as displayed in the figure below.
Mounting the Base Station Radio (BSR) 25 To wall mount the SDA-4S: 1. On the wall, mark the position of the two mounting hooks. The dimensions of the wall-mounting hooks are displayed in the template below. 2. Drill holes for each hole that you marked in the step above. 3. Insert wall anchors (supplied) into each of the drilled holes. 4. Insert the 9-inch screws (supplied) into the wall anchors. Ensure at least 2 mm of the screw is exposed to allow insertion into the SDA-4S mounting holes. 5. Hold the SDA-4S with both hands, and align the entrance to the two mounting hooks with 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.

Telephone (44) 1 895 467450. 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.
