Installation and Operation Manual; Version 1.1 May 22, 2000 Harmonix Corp. 1755 Osgood St. N. Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com GigaLINK Introduction and Overview: Thank you for choosing the Harmonix GigaLINK radio system. You have selected the world’s fastest commercially available radio system, thereby demonstrating a discerning grasp of the unique utility of our product. The Harmonix GigaLINK millimeter wave radio system represents an entirely new approach to broadband communications. Based on our extensive experience with millimeter wave systems for military and research applications, we now apply these techniques to a commercially priced version with our ultra-broadband family of GigaLink radio products. The Harmonix GigaLINK broadband radio systems operate in the newly allocated ISM band covering the frequency range of 59.05 – 64.0 GHz. Due to the unlicensed status of this band, no FCC license or special authorization is required to operate our GigaLINK systems. In addition, the high atmospheric absorption of RF energy at this frequency virtually eliminates any chance of interference from competing systems or unauthorized interception of the broadcast signal. The installation procedures detailed within this guide are similar to those used to install any wireless system. In fact, certain attributes of the 59.05 – 64.0 GHz band actually simplify deployment. The key to any successful installation project is proper planning and design. The Harmonix GigaLINK radio product has been designed for ease of installation and trouble-free operation. We recommend that you read and fully understand this guide prior to initiating the actual installation work. As stated above, the key to successful installation is proper system planning and execution. As with most wireless systems, the GigaLINK radio system requires un-obstructed Line of Sight (LOS) to operate reliably. Because of the extremely high data bandwidth provided by the GigaLINK system (100Mbps, OC3 or OC12) it is likely that our radio systems will be utilized as a critical or primary network connection. This absolute reliance on our systems for connectivity demands a focused attention to detail in order to assure un-interrupted operation. Each GigaLINK Radio system configuration is designed to provide a statistical availability of 99.99% for a specific path length. Failure to adhere to the recommend path limits will result in greatly reduced reliability and quality of service. Please follow the installation guidelines contained within and contact Harmonix directly with any questions or problems. The staff at Harmonix Corp. is dedicated to providing our customers the maximum utility in performance, reliability and speed.

Figure 1; below, details the absorptive properties of atmospheric O2 at a center frequency of 60GHz (indicated by the red arrow). Fig. 1 Oxygen Absorption Properties Fortunately, the atmospheric concentration of naturally occurring diatomic oxygen (O2) is relatively constant and expected absorption can be modeled accurately. In addition, the absorptive properties of oxygen dramatically reduce the likelihood of converging interfering signals. The effects of oxygen absorption, while a curse for those seeking long-distance transmissions, is a blessing for those seeking interference free wide-band RF connections up to 1 mile in range.

Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com Antenna Gain / Antenna Beamwidth: To increase the level of RF energy available to the radio receiver, Harmonix employs high performance high gain (directivity) antennae specifically selected for a given range. The gain of an antenna is increased by focusing the RF energy into a more confined pattern beamwidth. The antenna beamwidth is defined in degrees of an arc between to end points where the signal level is half that at the center of the beam (-3dB). Antenna radiation Pattern ) The relationship between antenna gain and beamwidth for standard GigaLINK antenna configurations is detailed below. Configuration Antenna Gain (dBi) 3dB Beamwidth Standard Patch > 30dBi 3.5° 13” Parabola > 38dBi 1.7° As shown in the diagram above, as the distance from the transmitter increases the size of the 3dB radiation pattern increases as a factor of the beamwidth. The signal however, is attenuated quickly in free space predominately by the effects of oxygen absorption in the 59-64GHz ISM Band (16dB/KM). During terminal alignment, the challenge is to focus the transmitter as precisely as possible onto the center of the receiving antenna. The received signal strength drops by half between the center point of focus and the 3dB edges of the receive pattern “spot”. Signal level 3dB points Beamwidth °

Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com Section 4; GigaLINK Installation Procedure Confirming Line of Sight (LOS) Without exception all microwave and millimeter wave wireless systems require unobstructed “Line of Sight” to operate reliably. In most cases, LOS can be confirmed visually, particularly in the case of a short-range product like the Harmonix GigaLINK system where both ends of a proposed link should fall within visual range. As noted in the previous section, the spot size of the 3dB antenna transmission pattern increases proportionately with range. Therefore, it is important to insure that the RF path is clear of obstructions for the entire 3dB beamwidth at any point along the transmission path. The diagram and formula shown below can be used to determine necessary clearance at any point along the RF path.

Therefore, no complex calculations to account for free space losses or rain fades are required. The maximum recommended range limits were calculated for a minimum fade margin of 10 dB under the worst rain conditions possible (25mm/hr.). In practice, except for ranges at the extreme limit of the envelope, actual fade margins will be higher. The most critical factor in achieving the desired reliability level is precision of the antenna alignment during installation. Failure to align both terminals on the center (optimum) region of the receive area will greatly reduce the level of signal received and in turn the available fade margin. Likewise, if the GigaLINK terminals are not mounted securely enough, misalignment from terminal movement due to wind or vibration can also result in unreliable operation.

Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com Selecting GigaLINK Terminal Locations: Several factors must be considered when selecting each GigaLINK terminal location. The ideal location for the GigaLINK terminals is one that provides un-obstructed Line of Sight and a stable/secure mechanical attachment point. In order of precedence primary considerations should include. • Locations with unobstructed Line of Sight to target terminal • Locations affording secure mechanical mounting provisions • Locations isolated from sources of vibration • Locations away from possible moving obstructions (workers, cranes etc.) • Locations accessible to service personnel for maintenance • Locations convenient to necessary power and network services. Harmonix supplies several installation kits for a variety of mounting techniques. The best mounting location and attachment method should be determined prior to equipment order during a detailed site survey. Selecting the Optimum Terminal Mounting Method: The following sections detail available mounting methods and hardware for the GigaLINK product. Mounting hardware to be specified at time of order.

Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com Required Installer Equipment The Harmonix GigaLINK system was designed to require a minimum of specialized equipment for installation, precision alignment and maintenance. A comprehensive, step-by-step troubleshooting guide with detailed test procedures and additional equipment recommendations is included in a later section of this manual. RF Terminal Alignment: After completing the initial mechanical installation and visual alignment steps the GigaLINK radio system is ready for final precision alignment. In order to complete precision alignment, Electrical service must be available at the power supply box and the DC power cable installed. Final alignment is performed on each terminal separately, by making very small alignment adjustments to optimize (peak) the received signal level. Each terminal alignment will be made in two steps. Step #1 Elevation (Vertical) Alignment Step #2 Azimuth (Horizontal) Alignment AGC Monitor Port To facilitate terminal alignment and to provide a quantitative measurement of alignment quality, the Harmonix GigaLINK terminal is provided with an AGC output monitor port. The AGC monitor port provides a positive voltage range of 3 – 4 volts DC to indicate the power level of the received signal. A simple self-ranging digital multimeter is all that is necessary to monitor the AGC level. Harmonix provides a SMA Male to pigtail jumper for attachment to the digital multimeter. The AGC monitor port is the primary tool for precision alignment and provides a tangible measurement to verify alignment during future maintenance visits.
Installation and Operation Manual; Version 1.1 May 22, 2000 Harmonix Corp. 1755 Osgood St. N. Andover, MA 01845 (978) 974 0931, (978) 974 0969 fax www.hxi.com Monitor Measurement in Radio “Listening Mode” Prior to applying modulation to the Harmonix GigaLINK system it is necessary to measure AGC Monitor voltage output with no modulation applied. By this method it is possible to identify potential sources of in-band interference and avoid interfering with other installed systems. If a AGC Monitor Voltage in excess of 3VDCis detected, this indicates the presence of a competing system and make unintended interference possible. In the event that potential interference is detected measures must be taken to avoid transmission of potentially interfering signals. These measures include relocating the terminal at least 6 Meters away and/or changing the terminal polarization by rotating both terminals 90 deg. On- axis. The standard GigaLINK mounting hardware enables quick polarization changes. For details on accomplishing these changes please contact the factory. If after changing the polarization an AGC voltage in excess of 3 VDC is detected, the radio system must be exchanged for a system of a alternative frequency. Loop-Back Fiber Jumper Also included in all Harmonix Installation kits is a fiber jumper of the correct mode and termination type. This fiber jumper is used to “Loop-back” GigaLINK terminals during alignment. Generating Modulation for the Purposes of Terminal Alignment: In the absence of actual network traffic, a modulation must be applied at the terminal “IN” port to excite the radio fiber modem and modulate a transmitted signal. This modulation can be created by artificial means to drive the radio transmitter to a high enough RF level to facilitate alignment. Harmonix offers GigaLINK models in (3) popular data protocols 100Mbps FX, OC3 and OC12. An OC3 modulation source is suitable for modulating all three protocols for the purposes of alignment only. Harmonix recommends the FLUKE OC3Port Plus OC3/ATM Handheld Test set for this application. In addition, depending on the intelligence and built in test capability of the customer premises equipment, a suitable test signal may be available from the network hub, switch or ATM switch.

Follow the specific steps as detailed on the following page to achieve final (precision) alignment. Elevation Alignment Assuming that a rough mechanical alignment for both azimuth and elevation were performed as outlined in the previous section, elevation alignment can now be performed. The following steps detail the elevation alignment procedure. Best results will be achieved when care is taken to make small incremental adjustments. Small adjustment at the radio terminal translate to much larger changes at the remote terminal. 1.) Slightly loosen the (4) 13mm bolts that lock the elevation adjustment bracket. 2.) Measure the voltage present at the monitor port via pigtail and multimeter. 3.) Slowly tilt radio up or down until increasing AGC voltage is observed. Continue minute adjustment until voltage begins to fall, then return to the position where the highest voltage was observed. 4.) When satisfied that peak voltage has been achieved tighten top (2) elevation adjuster bolts to maintain position. Remote GigaLINK Terminal with Fiber Jumper installed and Power on. Modulation Source GigaLINK Terminal to be Aligned with Modulation Source connected and Power on.

Slightly loosen the single 13mm bolt that locks the azimuth adjustment to the “L” Bracket. 2.) Measure the voltage present at the AGC monitor port via pigtail and multimeter. 3.) Slowly rotate radio left or right until increasing AGC voltage is observed. Continue minute adjustment until voltage begins to fall, then return to the position where the highest voltage was observed. 5.) When satisfied that peak voltage has been achieved tighten azimuth adjuster bolt to maintain position. When the initial azimuth alignment has been completed repeat the elevation alignment again followed by the azimuth alignment until confident that the AGC voltage is peaked. Repeat the procedure outlined above for the remote terminal following the same methodology. In most cases several incremental alignments in both planes at both terminals will be necessary to achieve optimum alignment for the link.
