IntroductionSU-R Installation Manual 1 BreezeACCESS MMDS Series1. INTRODUCTIONThis manual describes installation guidelines for BreezeACCESS MMDS SU-R Subscriber Units.The BreezeACCESS Broadband Wireless Access system allows access service providers toprovide high-speed IP connectivity services to their subscribers. To support IP-based serviceseffectively BreezeACCESS systems employ wireless packet data switching technology.The BreezeACCESS MMDS line of products uses Frequency Hopping Spread Spectrum radiosthat operate in Time Division Duplex (TDD) mode in the 2.500GHz – 2.686GHz frequencyrange.The SU-R-MMDS line of Subscriber Units comprises compact units that are designed for indoorinstallation. SU-R units are available in several models differing from each other in the type ofsupported data networks and availability of voice services as follows:• SU-R-8D units support up to 8 Ethernet workstations / PCs (8 MAC addresses).• SU-R-BD units provide a full bridge functionality supporting up to 512 MAC addresses.• SU-R-8D1V support up to 8 Ethernet workstations / PCs and have an interface to a standardtelephone set.SU-R-MMDS units are available either with an indoor wall/window mountable 7 dBi UNI-7antenna (-A7 models) or with an adapter for an external separate antenna.Note: The information contained in this manual is applicable to BreezeACCESS SU-R-MMDSunits with software release 3.0 and up.

Basic InstallationBreezeACCESS MMDS Series 2 SU-R Installation Manual2. BASIC INSTALLATION2.1 Packing ListThe SU-R units are shipped with the following units and accessories. The exact packing listvaries depending on system configuration and ordered equipment.• SU-R unit• An SMA adapter• A 7 dBi UNI-7 antenna eith a 3 m cable and a wall mounting kit (with A7 models only)• A power supply• Wall mounting kit for the SU-R unit (two anchors and screws)• An Ethernet cable (straight)2.2 Other Required ItemsThe following items must be available for the installation• Antenna*and RF cable*for models that are supplied without an antenna• An Ethernet cable (crossed) if the unit should be connected to a hub (the straight Ethernetcable supplied with the unit is intended for connecting it directly to a PC or to a hub’s uplinkport)• A PC with terminal emulation program• A monitor cable* for configuration and testing via the Monitor interface• Installation tools and materialsItems marked with an asterisk (*) are available from BreezeCOM.

Basic InstallationSU-R Installation Manual 3 BreezeACCESS MMDS Series2.3 Installation OverviewStandard installation involves the following steps:1. Verify that all components of the packing list, described in Section 2.1, are intact and verifyavailability of the required items listed in Section 2.2.2. Install the unit and antenna in optimal locations as described in Sections 2.4 and 2.5 and inthe instructions supplied with the antenna.Note: To avoid drilling unnecessary holes, it is recommended to verify good connectivity with thebase station prior to drilling holes in the locations intended for the SU-R unit and/or theindoor antenna.3. Connect the antenna to the unit as described in Section 2.6.4. Connect the power supply and the user’s equipment to the unit as described in Section 2.7 .5. Configure the basic system parameters as described in Section 3.6. Align the antenna for optimal connectivity and configure the Maximum Data Rate ifapplicable, as described in Chapters 4 and 5.7. Check the functionality of the unit as described in Chapter 6.2.4 Installation GuidelinesThis section describes the installation guidelines and the various considerations that must betaken into account when planning the installation.2.4.1 Location of the Unit• The unit can be placed on a desktop or a shelf, or can be attached to a wall.• The unit should be installed as neat as possible to the antenna (-A7 models). The RF cableconnecting the unit to the antenna should be as short as possible to guarantee minimum powerloss.

Basic InstallationBreezeACCESS MMDS Series 4 SU-R Installation Manual• Keep the units well away from sources of heat, such as radiators, air-conditioners, etc.2.4.2 Location of the Antenna• Any physical object in the path between two units can cause signal attenuation. Commonobstructions are buildings and trees. If a unit’s antenna is installed indoors, the walls and/orwindows between the two sites are physical obstructions. If the antenna is positionedoutdoors, any buildings or other physical structure such as trees, mountains or other naturalgeographic features higher than the antenna and situated in the path between the two sites canconstitute obstructions.• Install indoor antennas as close as possible to a window (or wall if a window is notaccessible) facing the required direction. The UNI-7 antenna may also be attached to a fixedwindow. Avoid metal obstacles such as metal window frames or metal film anti-glarewindows in the transmission path. Install outdoor antennas high enough to avoid any obstacles,which may block the signal.• Position the antennas clear of metal furniture and away from moving metal objects such asmetal fans or doors.2.4.3 Antenna DiversityIn applications where no multipath propagation is expected, a single antenna is sufficient to ensuregood performance levels. However, in cases where multipath propagation exists, BreezeCOMrecommends that two antennas be used. This takes advantage of space diversity capabilities. Byusing two antennas per unit, the system can select the best antenna on a per-packet basis (everyseveral milliseconds).Multipath propagation is to be expected when there are potential reflectors between the AccessUnit and Subscriber Units. These reflectors may be buildings or moving objects such as airplanesand motor vehicles. If this is the case, the radio signal does not travel in a straight line, but isreflected or deflected off of the object, creating multiple propagation paths.When installing a single antenna, modify the transmit diversity option to either antenna 1 orantenna 2, according to the antenna being used.2.4.4 Antenna PolarizationAntenna polarization must be the same at either end of the link. In most applications, the preferredorientation is vertical polarization. Above-ground propagation of the signal is better when it ispolarized vertically. To verify antenna polarization, refer to the assembly instructions supplied

Basic InstallationSU-R Installation Manual 5 BreezeACCESS MMDS Serieswith the antenna set. For the detached UNI-7 antenna (A7 model) follow the instructions includedwith the antenna.2.4.5 Antenna SealWhen using outdoor antennas, you must seal the antenna connectors against rain. Otherwise, theantennas are not suitable for use in outdoor installations.2.4.6 Lightning ProtectionLightning protection is designed to protect people, property and equipment by providing a path toground for the lightning’s energy. The lightning arrestor diverts the strike energy to ground througha deliberate and controlled path instead of allowing it to choose a random path. Lightningprotection for a building is more forgiving than protection of electronic devices. A building canwithstand up to 100,000 volts, but electronic equipment may be damaged by just a few volts.Lightning protection entails connecting an antenna discharge unit (also called an arrestor) to eachcable as close as possible to the point where it enters the building. It also entails proper groundingof the arrestors and of the antenna mast (if the antenna is connected to one).The lightning arrestor should be installed and grounded at the point where the cable enters thebuilding. The arrestor is connected to the unit at one end and to the antenna at the other end.The professional installer you choose must be knowledgeable about lightning protection. Theinstaller must install the lightning protector in a way that maximizes lightning protection.AL 1 Lightning Arrestor - Part No. 872905 5 ft (1.5m), “N” Male to “N” Female is available fromBreezeCOM.Note: Detached outdoors antennas should be installed ONLY by experienced antenna installationprofessionals who are familiar with local building and safety codes and, whereverapplicable, are licensed by the appropriate government regulatory authorities.Failure to do so may void the BreezeACCESS Product Warranty and may expose the enduser to legal and financial liabilities. BreezeCOM and its resellers or distributors are notliable for injury, damage or violation of government regulations associated with theinstallation of detached antennas.

Basic InstallationBreezeACCESS MMDS Series 6 SU-R Installation Manual2.5 Wall Mounting the UnitNote: To avoid drilling unnecessary holes, it is recommended to verify connectivity with the basestation prior to drilling holes in the locations intended for the SU-R unit and/or the indoorantenna.The drill template on the packaging box can be used to mark the locations of the screws on thewall (drill right through the markings on the drill template).After insertion of the anchors and screws, hang-on the unit on the two screws with the bottompanel (the side with the connectors) facing downward.2.6 Connecting the Antenna1. Connect the special adapter to antenna port 1 (marked 1) on the side of the unit. Push theadapter carefully into the hole using the alignment markings on the adapter and the unit, andturn it 180 degrees to firmly lock it.2. Connect the antenna cable to the adapter. If you use a heavy cable, secure the cable so as toprevent applying excessive force on the adapter and connector.2.7 Connecting the Unit to the Power Supply and to the CPEThe unit operates on a power input of 5V DC, supplied by the power transformer included withthe unit.1. Plug the output jack of the power transformer into the DC input jack (marked DC IN)located on the bottom panel of the unit.2. Connect the supplied universal power transformer to a power outlet - 110/ 220VAC.3. Use a straight Ethernet 10BaseT cable to connect the Ethernet port (marked ETH) to a PC orto a hub’s uplink port. Use a crossed cable to connect to a hub.4. For units with voice support, use the standard cable connected to the telephone set toconnect the telephone to the telephone port (marked TEL).

Aligning the AntennaBreezeACCESS MMDS Series 12 SU-R Installation Manual4. ALIGNING THE ANTENNAWhen using high gain antennas with a narrow beam width, an alignment procedure is necessary inorder to optimize the quality of the link with the Access Unit.For a Subscriber Unit with a directional antenna, you can either use the LED indicators on thefront panel of the unit or view the Received Signal Strength Indication (RSSI) using the monitorprogram. In most installations, alignment using the LEDs is sufficient. The RSSI reading can beused when finer alignment is required (see 3.2).Note: Antenna alignment of the Subscriber Unit is possible only after the Access Unit you wish toassociate with is operational and the basic parameters were properly configured asdescribed in Section 3.2.4.1 Aligning the Antenna Using the LEDs1. The H (high), M (medium) and L (low) LEDs on the front panrel of the unit indicate thequality of the link. The higher the number of illuminated LEDs the better is the quality of thelink.2. Rotate the antenna left and/or right until you reach the point of maximal signal qualityreading on the H, M and L LEDs. Make sure that at all times, the front of the antenna facesthe general direction of the Access Unit. In some cases, e.g. when the unit is very close tothe base station you may need to tilt the antenna upward or downward.3. For proper operation, at least one (L) LED should be illuminated. If this is not possible,improve the link quality by placing the antenna at a higher point or in a different location.4. After the antenna is optimally aligned, secure the antenna to guarantee that it will remain inthe selected position.4.2 Aligning the Antenna Using the Site Survey Menu1. Start the Monitor program as described in Section 3.1.

Aligning the AntennaSU-R Installation Manual 13 BreezeACCESS MMDS Series2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start the ContinuousLink Quality Display. Each line in the display includes the number of frames that werereceived since the last measurement (total Rx) and the average RSSI for these frames.3. Rotate the antenna left and/or right (or tilt it upward/downward) until you reach the point ofmaximum RSSI reading. Make sure that at all times, the front of the antenna faces the generaldirection of the Base Station.4. For proper operation, the RSSI reading should be at least 38 units. When the maximumreading is less than 43 units, try to improve it by placing the antenna at a higher point or in adifferent location. For best performance it is recommended that the RSSI be higher than 65.5. Press the Esc key to stop the test.6. Secure the antenna to guarantee that it will remain in the selected position.

Maximum Data Rate ConfigurationBreezeACCESS MMDS Series 14 SU-R Installation Manual5. MAXIMUM DATA RATE CONFIGURATION1. If the average RSSI reading using the Continuous Link Quality Display (see Section 4.1) islower than 65, the unit should be configured in accordance with the following table:RSSI RecommendedMaximum Data RateRSSI > 65 3Mbps53 < RSSI < 65 2MbpsRSSI < 53 1Mbps2. From the main menu, type 3 to access the Basic Configuration menu. Type 5 to access theMaximum Data Rate menu.• Type 3 (3Mbps) if the RSSI reading is higher than 65 units.• Type 2 (2Mbps) if the RSSI reading is between 53 to 65 units.• Type 1 (1Mbps) if the RSSI reading is lower than 53 units.3. Reset the unit for the new configuration to become effectiveSee Appendix C for more details on the Maximum Data Rate parameter.

The ESSID is a string used to identify a wireless network. It prevents theunintentional merging of two co-located wireless networks. An SU can only associate with anAU that has an identical ESSID. Use different ESSIDs to segment the wireless access networkand add security to your network. The default value is ESSID1.

Appendix C. Basic ParametersBreezeACCESS MMDS Series 26 SU-R Installation ManualNote: The ESSID string is case-sensitive.• Maximum Data Rate – Displays the current maximum data rate, and allows entry of a newvalue for the maximum data rate.BreezeACCESS units operate at 1 Mbps, 2 Mbps or 3 Mbps. Under certain conditions(compatibility reasons or range/speed trade-off), you may decide to limit the use of higherrates. If the quality of the link is not good enough, it is recommended to decrease the value ofthese parameters (the higher the date rate, the higher the error rate). Otherwise, there is a highprobability that the unit will have to retransmit many frames several times before temporarilyreducing the data rate. A high number of retransmissions reduces the overall throughput forthe selected SU as well as for all the other SUs served by the same AU.The link quality can be estimated based on the RSSI measurement using the Continuous LinkQuality Display in the SU. If the measured RSSI is less than a certain threshold, it isrecommended to decrease the Maximum Data Rate of the SU in accordance with the followingtable:Recommended Maximum Data Rate 3Mbps 2Mbps 1MbpsBreezeACCESS MMDS SU-I/ID RSSI>65 53<RSSI<65 RSSI<53The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.The AU learns the Maximum Data Rate used by each SU during the association process, anduses this rate for transmissions to the specific SU.• Flexible Hopping Definition – Allows adding and removing frequencies to the list ofhopping frequencies; displays the selected hopping frequencies and the current hoppingsequence (based on the previous selections made before the last Reset). The new selectionswill come into effect only after the next Reset.The Flexible Hopping is based on using the standard MMDS 6MHz channels and frequencies.See Appendix C for a detailed list of the standard channels, as well as the frequency band andthe hopping frequencies for each of these channels.The Flexible Hopping menu includes the following options, allowing adding/removingstandard MMDS channels or adding/removing discrete standard hopping frequencies.

Appendix C. Basic ParametersSU-R Installation Manual 27 BreezeACCESS MMDS Series⇒ Add Frequencies – Allows adding discrete hopping frequencies or frequency ranges.Enter a list of frequencies and/or frequency ranges to be added, e.g. 2501.500,2507.500-2519.500, 2525.500.Use a comma to separate between entries (no spaces). The allowedentries are from 2500 to 2688 in steps of 0.5MHz. The frequencies (either the start andstop frequencies of a range or discrete frequencies) can be in the following formats: MHz Resolution, e.g. 2520 kHz resolution, e.g. 2501.000,2505.500 (you must enter 3 digits after the dot). The minimal channel spacing between frequencies is 3MHz. When entering a range, this willbe the default channel spacing (e.g. for the range 2510-2516 the hopping frequencies willbe 2510, 2513 and 2516 MHz). It is recommended to use the standard MMDS frequencies. See Appendix C for a list of thestandard MMDS frequencies.⇒ Remove Frequencies - Allows removing frequencies from the existing list. Enter a list offrequencies and/or frequency ranges to be removed, using the same guidelines as in AddFrequencies above⇒ Add Channels – Allows defining a new list of channels or adding channels to an existinglist. Enter a list of channels to be added, e.g. A1,B3,D2. Use a comma to separatebetween entries (no spaces). See Appendix C for a list of the channels and the hoppingfrequencies for each of the channels.⇒ Remove Channels – Allows removing channels from existing list. Enter a list of channelsto be removed, using the same guidelines as in Add Channels above.⇒ Erase All – Allows erasing all the entries from the list.⇒ Show Flexible Hopping Parameters – Allows viewing the following information:∗ An updated list of the defined sub-bands and discrete frequencies to become effectiveafter the next Reset. A sub-band is defined by the first and last hopping frequency in aseries of consecutive frequencies, with 3MHz separation between frequencies.∗ An updated list of all the hopping frequencies to be used after the next Reset.∗ The current sequence of operational hopping frequencies• Transmit Antenna – Displays which antennas are used for transmission. SU-R units supporttransmit antenna diversity (2 antennas). During reception, a BreezeACCESS unit that isconnected to two antennas dynamically selects the antenna where reception is optimal. Incontrast, if the transmit antenna diversity is enabled, the unit selects the antenna from which it

Appendix C. Basic ParametersBreezeACCESS MMDS Series 28 SU-R Installation Manualwill transmit before the actual transmission. It usually uses the antenna last used forsuccessful transmission. In installations where a model that can support antenna diversity isconnected to a single antenna, Transmit Antenna Diversity should be configured to transmitonly from that single antenna. Available selections are:⇒ Use Two Antennas⇒ Use Antenna No. 1⇒ Use Antenna No. 2The default selection is Use Antenna No. 1 for SU-R units where a single antenna isconnected to antenna port 1.
