1. INTRODUCTION This manual describes installation guidelines for BreezeACCESS/MMDS SU-I and SU-ID Subscriber Units. The BreezeACCESS IP Broadband Wireless Local Loop (WLL) system allows access service providers to provide high-speed IP connectivity services to their subscribers. To support IP-based services effectively BreezeACCESS systems employ wireless packet data switching technology.
Basic Installation 2. BASIC INSTALLATION 2.1 Packing List The SU-I/ID units are shipped with the following units and accessories. The exact packing list varies depending on system configuration and ordered equipment. • • • • SU-I unit (with two integral antennas) or SU-ID unit (without antennas) A 5 VDC universal power supply transformer Mounting bracket for wall or ceiling installation A torque key for antenna connectors (SU-ID units) 2.
Basic Installation 2.3 Installation Overview Standard installation involves the following steps: 1. Verify that all components of the packing list, described in Section 2.1, are intact and verify availability of the required items listed in Section 2.2. 2. Install the unit and antenna(s) in optimal locations as described in Section 2.4. 3. Connect the antenna(s) to the unit as described in Section 2.6.(SU-ID units) 4. Connect the power supply to the unit as described in Section 2.7. 5.
Basic Installation • For most applications, the most convenient choice is to use SU-I units, equipped with two integral 2dBi omni antennas. 2.4.2 Location of the Antenna(s) • Any physical object in the path between two units can cause signal attenuation. Common obstructions are buildings and trees. If a unit’s antenna is installed indoors, the walls and/or windows between the two sites are physical obstructions.
Basic Installation When installing a single antenna, modify the transmit diversity option to either antenna 1 or antenna 2, according to the antenna being used. 2.4.4 Antenna Polarization Antenna polarization must be the same at either end of the link. In most applications, the preferred orientation is vertical polarization. Above-ground propagation of the signal is better when it is polarized vertically. To verify antenna polarization, refer to the assembly instructions supplied with the antenna set.
Basic Installation The professional installer you choose must be knowledgeable about lightning protection. The installer must install the lightning protector in a way that maximizes lightning protection. BreezeCOM offers the following high-quality lightning arrestor assembly: BreezeACCESS AL 1 Lightning Arrestor - Part No. 872905 5 ft (1.5m), “N” Male to “N” Female.
Basic Installation Figure 2-1. Wall Mounting the Unit Special slots have been added to the wall mounts to allow for unobtrusive cable installation. These slots should be used to fasten cables coming out of the unit to the wall mounts, eliminating loose or tangled cable installations. Convenience M ounting Slots Unit M ounting Slots Cable Fastening S lots Figure 2-2.
Basic Installation 2.6 Connecting Antenna(s) to the Units (SU-ID units only) For installation convenience, a torque key is included with all BreezeACCESS SU-ID units. WARNING: The use of improper tools for tightening antenna connection cables to BreezeACCESS SU-I units may result in damage to the cable connectors. Use the included torque key to tighten the cable(s) to the connector(s) on the side of the SU-I unit.
Basic Installation 2.7 Connecting the Unit to the Power Supply and to the CPE The unit operates on a power input of 5V DC, supplied by the power transformer included with the unit. 1. Plug the output jack of the power transformer into the DC input jack located on the rear panel of the unit. 2. Connect the supplied universal power transformer to a power outlet - 110/ 220VAC. 3.
Configuring System Parameters 3. CONFIGURING SYSTEM PARAMETERS After completing the installation process, as described in the preceding sections of this manual, proceed with configuration of the basic system parameters. This manual covers the configuration of basic installation parameters. Refer to the Administration Manual for information related to other parameters. Note: Optionally, the product can be configured using Telnet over the Ethernet port, after setting IP address.

If Flexible Hopping was selected in the Hopping Band selection menu, type F to access the Flexible sub-bands Definition menu. Use the Add/Delete subbands screens to define the required frequencies. See Appendix C for a list of the standard frequencies as a function of the allocated channel(s). 9. Type G to access the Transmit Antenna selection screen.
Aligning the Antenna 4. ALIGNING THE ANTENNA Omni and low gain antennas do not require alignment due to their wide radiation pattern. High gain antennas have a narrow beamwidth, necessitating an alignment procedure in order to optimize the link. For Subscriber Units with directional antenna(s), you can either use the LED indicators on the front panel of the unit or view the Received Signal Strength Indication (RSSI) on the monitor. In most installations, alignment using the LEDs is sufficient.
Aligning the Antenna 4.2 Aligning the Antenna Using the Site Survey Menu 1. Start the Monitor program as described in Section 3.1. 2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start the Continuous RSSI Display. Each line in the display includes the number of frames that were received since the last measurement (total Rx) and the average RSSI for these frames. 3. Rotate the antenna left and/or right until you reach the point of maximum RSSI reading.
Maximum Data Rate Configuration 5. MAXIMUM DATA RATE CONFIGURATION 1. If the average RSSI reading using the Average RSSI Continuous Display is lower than 76, the default data rate of 3 Mbps is too high and the data rate of the unit should be configured accordingly: 2. From the main menu, type 3 to access the Basic Configuration menu. Type 5 to access the Maximum Data Rate menu. L Type 3 (3Mbps) if the RSSI reading is higher than 76 units. LL Type 2 (2Mbps) if the RSSI reading is between 66 to 76 units.
Verifying Proper Operation 6. VERIFYING PROPER OPERATION After completing the installation, and after connecting the unit to the AC mains, the system starts operation. To verify proper operation, view the LED panel located on the front panel of the unit. Table 6-1 lists the various LED states. Table 6-1.
