IntroductionBreezeACCESS MMDS Series 1 SU A/E Subscriber Units Installation Manual1. INTRODUCTIONThis manual describes installation guidelines for BreezeACCESS MMDS SU-Aand SU-E series of Subscriber Units.The BreezeACCESS IP Broadband Wireless Local Loop (WLL) system allowsaccess service providers to provide high-speed IP connectivity services to theirsubscribers. To effectively support IP-based services BreezeACCESS systemsemploy wireless packet data switching technology.The BreezeACCESS MMDS line of products uses Frequency Hopping SpreadSpectrum radios that operate in Time Duplex Division (TDD) mode in the2.500GHz – 2.686GHz frequency range.SU-A and SU-E series Subscriber Units are comprised of an indoor unit (SU-NI)and an outdoor unit. In the SU-A product line, the outdoor unit (SU-RA) containsthe radio module and an integral flat antenna. In the SU-E series, the outdoor unit(SU-RE) contains the radio module and an interface to an external antenna (notincluded). The indoor unit provides the interface to the user’s equipment and ispowered from the mains via its SU-PS power supply unit. The SU-NI alsocontains an IF (Intermediate Frequency) module and is connected to the outdoorunit via a 50-ohm coaxial IF cable. The IF cable serves for transmission of the440MHz IF signal between the indoor and the outdoor units. It also serves fortransferring power (12VDC), management and control signals from the indoorunit to the outdoor unit.The SU-A/E-D-MMDS series include the following products:• SU-A/E-1D-MMDS: supports a single Ethernet device• SU-A/E-8D-MMDS: supports up to 8 Ethernet workstations/PCs• SU-A/E-BD-MMDS: supports a LAN (a bridge functionality)Note: The information contained in this manual is applicable to BreezeACCESSMMDS units with software release 2.3.

BASIC InstallationBreezeACCESS MMDS Series 5 SU A/E Subscriber Units Installation Manual2.4 Guidelines for Selection of Equipment LocationsSelect appropriate locations for the Outdoor unit and for the Indoor unit using thefollowing guidelines.SU-RA• The SU-RA Outdoor unit should be mounted on a pole and should beinstalled on a rooftop or a side-wall where a direct line of sight with the BaseStation antenna can be established. The higher the unit, the better theachievable link quality.• The antenna (integrated on the front side of the SU-RA Outdoor unit) shouldbe directed towards the Base Station. The unit should be installed in a waythat allows optimal alignment towards the Base Station. The location shouldalso be selected to allow easy access to the unit for installation and testing.SU-RE• The SU-RE outdoor unit should be installed as near as possible to itsantenna.SU-RA/RE• The SU-RA/RE is connected to the SU-NI by means of an IF cable carryingsignaling, control signals and power. The IF frequency is 440 MHz. Themaximum allowed attenuation of the IF cable connecting the Outdoor unit tothe Indoor unit is 15dB and the maximum allowed DC resistance (the sum ofthe DC resistance of the inner and outer conductors) is 1.5 ohm. This allowsfor cable length of up to 30m when using the standard RG 58 cable. If longer cables are required, a cable with lower attenuation and/or DCresistance should be used. Table 1 provides details regarding some popularcables such as the RG 58 and RG 213. If the spectral environment is pollutedwith noise in the 440 MHz band, it is recommended to use a higher qualitydouble-shielded cable such as the LMR 240 or LMR 400 (manufactured byTimes Communications). Table 1: IF Cables Cable Type RG 58 RG 213 LMR 240 LMR 400

Aligning the AntennaBreezeACCESS MMDS Series 17 SU A/E Subscriber Units Installation Manual4. ALIGNING THE ANTENNANote: Antenna alignment using the RSSI bar display is possible only after theAccess Unit you wish to associate with is operational and the ESSID,Hopping Band and Frequency Offset parameters were properly configured.Otherwise the unit will not be able to synchronize and associate with theAccess Unit. As the RSSI measurement is performed on received frames, itsresults are meaningless as long as the unit is not associated with an AU.1. Verify that the Power indication (the Yellow LED of the BSSI bar display) isON. ETHALARM RSSIIFWLNKFigure 4-1. SU-RA/RE Outdoor Unit Bottom Panel2. Align the antenna (integrated into the front side of the SU-RA Outdoor unit,or separate if the unit is an SU-RE) to point towards the general direction ofthe base station.3. The RSSI bar display is located on the bottom panel of the Outdoor unit(refer to Figure 4-1). The 8 green RSSI LEDs are used for reading theReceived Signal Strength Indication. The higher the number of green LEDsthat are ON, the higher the level of the received signal. Rotate the antennaleft and/or right until you reach the point of maximum RSSI reading. Makesure that at all times, the front of the antenna faces the general direction ofthe base station.

Aligning the AntennaSU A/E Subscriber Units Installation Manual 18 BreezeACCESS MMDS Series4. For proper operation, at least one green LED should be ON. If you cannotreach a point where at least one green LED is ON, try to improve thereception quality by placing the antenna at a higher point or in a d9ifferentlocation.Note: In some cases (e.g., when the Subscriber Unit is very close to the BaseStation), the antenna might have to be installed at an appropriate angle, inorder to ensure that it is directed towards the Base Station antenna).5.
