B-18 N2-X Ethernet Extender Installation and Operation Manual Welcome! Welcome to the Wireless, Inc. N2-ACCESSTM Series product family. This manual is designed to introduce you to the N2- X Ethernet ExtenderTM, and to provide you with information necessary to plan, install, operate and maintain a N2- X Ethernet Extender wireless communication system. The N2-X Ethernet Extender is intended for professional installation only. This manual, however, is also designed for personnel who plan, operate and administrate the N2- X Ethernet Extender communication system. Please review the entire manual before powering up or deploying any N2- X Ethernet Extender. Updates to this manual will be posted on the Wireless, Inc. Customer Service Website at http://www.wire-less-inc.com. Registered Wireless customers can access Wireless’ on-line information and support service, available 24 hours a day, 7 days a week. Our on-line service provides users with a wealth of up-to-date information, with documents being added or updated each month. Radiation Warnings Microwave Radio Radiation Warning Under normal operating conditions, N2- X Ethernet Extender radio equipment complies with the limits for human exposure to radio frequency (RF) fields adopted by the Federal Communications Commission (FCC). All Wireless, Inc. microwave radio equipment is designed so that under normal working conditions, microwave radiation directly from the radio is negligible when compared with the permissible limit of continuous daily exposure recommended in the United States by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. Microwave signal levels that give rise to hazardous radiation levels can exist within transmitter power amplifiers, associated RF multiplexers, and antenna systems. Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation. Do not disconnect RF coaxial connectors, open microwave units, or break down any microwave screening while the radio equipment is operating. vi N2-X Ethernet Extender Installation and Operation Manual Microwave Antenna Radiation Warning Designed for point-to-point operation, an N2- X Ethernet Extendermicrowave radio system will use directional antennas to transmit and receive microwave signals. These directional antennas are usually circular or rectangular in shape, are generally located outdoors, and are usually mounted on a tower or mast. Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal Communication Commission’s Office of Engineering & Technology, limits for maximum permissible exposure (MPE) to microwave signals have been adopted by the FCC for both Occupational/Controlled environments and General Population/Uncontrolled environments. These limits are 5.0 mW/ cm2 and 1.0 mW/cm 2, respectively, with averaging times of six-minutes and thirty-minutes, respectively. The closer you are to the front center-point of a microwave antenna, the greater the power density of its transmitted microwave signal. Unless you are very close, however, microwave exposure levels will fall far below the MPE limits. To determine how close to a microwave antenna you can be and still remain below the MPE limits noted above, “worst case” predictions of the field strength and power density levels in the vicinity of an N2- X Ethernet ExtenderTM microwave antenna can be made from the following calculations. The equation is generally accurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e. close to the antenna). S = PG/4πR2 where: S = power density (in mW/cm 2) P = power input to the antenna (mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (cm) Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and must be converted using the following equation: G = 10 dB/10 For example, a logarithmic power gain of 24 dB is equal to a numeric gain of 251.19. Assuming (1) maximum output power from the N2- X Ethernet Extender (+3.5 dBm [2.238 mW]), (2) no signal loss in the cable connecting the N2-X Ethernet Extender to the antenna, and (3) the use of a 27 dBi gain parabolic antenna, the 5.0 mW/cm2 and 1.0 mW/cm 2 MPE power density limits would be reached at distances of approximately 4.22 cm and 9.44 cm, respectively. Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnel maintain appropriate distances from the front of all directional microwave antennas. Should you have questions about N2-X Ethernet ExtenderTM microwave signal radiation, please contact the Wireless, Inc. Customer Service Department. vii N2-X Ethernet Extender Installation and Operation Manual Notice Regarding Operation pursuant to FCC part 15 Rules This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. viii N2-X Ethernet Extender Installation and Operation Manual 1.0 General Overview 1.1 N2-ACCESS Series Product Family All N2-X Ethernet Extender radios are members of the N2-ACCESS Series radio product family. The N2- ACCESS Series is designed to provide an economical wireless solution for local access telecommunication requirements. The N2-ACCESS Series radio product family consists of several product offerings, to include both the N2-ACCESS Link. This manual addresses, in detail, the operation of the N2-X Ethernet Extender. For detailed information on other N2-X Ethernet Extender radios or other members of the N2-ACCESS Series, please refer to the appropriate Operation Manual(s). 1.2 Introduction to the N2-X Ethernet Extender The N2-X Ethernet Extender series of radios are designed for operation in two of the Unlicensed National Infrastructure at frequencies of 5,250 - 5,350 MHz or 5,725 - 5,825 MHz. Each N2-X Ethernet Extender is comprised of a pole mounted RF/antenna unit. Each link is powered by means of a AC wall transformer (optional DC powering available) located with the indoor terminal unit. The system has a data transmission capacity of 16 Mb/s. Refer to the N2X Ethernet Extender data sheets for information relating to product offerings and specifications. N2-X Ethernet Extender Installation and Operation Manual 1.3 Regulatory Information In January 1997, the FCC made available 300 MHz of spectrum for Unlicensed National Information Infrastructure (U-NII) devices. The FCC believes that the creation of the U-NII band will stimulate the development of new unlicensed digital products which will provide efficient and less expensive solutions for local access applications. The U-NII band is divided into three sub bands at 5.15 - 5.25, 5.25 - 5.35 and 5.725 - 5.825 GHz. The first band is strictly allocated for indoor use and is consistent with the European High Performance Local Area Network (HIPERLAN). The second and third bands are intended for high speed digital local access products for “campus” and “short haul” microwave applications. Table 1.1 - FCC U-NII Bands Band 1 Band 2 Band 3 5.15 to 5.25 GHz 5.25 to 5.35 GHz 5.725 to 5.825 GHz Power (Max) 200 milliwatts EIRP 1 watt EIRP 4 watts (EIRP)* Intended Use Indoor Use Only Campus Approx 10 miles Frequency * Note: A recent FCC memorandum opinion and order (M00) revised on June 24, 1998 allows the use of a directional antenna with 23 dBi gain and a maximum transmitter output power of 1 watt in the 5.725 - 5.825 U-NII band. WL035901 N2-X Ethernet Extender Installation and Operation Manual 2.0 N2-X Ethernet Extender Product Profile 2.1 General Overview The N2-X Ethernet Extender series of microwave radio products provides digital capacities for 16 Mb/s data rates for short-haul applications up to 10 km. The radio terminal operates in the newly allocated Unlicensed National Information Infrastructure (U-NII) spectrum with a revolutionary Split Modulation system architecture that provides full duplex operation in the 5.3/5.7 GHz U-NII frequency bands. The N2-X Ethernet Extender series provides the unique advantage of a very robust digital transmission scheme. Split Modulation uses two separate 100 MHz bands within the U-NII frequency spectrum. Within these bands, the N2-X Ethernet Extender series operates in one of many independent channels providing for frequency reuse and network flexibility, ideal for dense network applications. Synthesized RF channel selection is field configurable, as are the power output options for the selection of antenna sizes. Frequency coordination and installation guidelines are provided in the appendix section of this manual. Complying with all aspects of FCC Rules Subpart 15.401-15.407, the transmission characteristics of the N2-X Ethernet Extender series are ideally suited to meet the peak power spectral density requirements of the U-NII 5.250 - 5.350 and 5.725 - 5.825 GHz bands. Note: From this point on in this Operations Manual, unless specified otherwise, the term N2X Ethernet Extender refers to the 5.3/5.7 GHz N2-X Ethernet Extender radio. The N2-X Ethernet Extender as been designed for complete front access to all interfaces, controls and displays. Information in this manual will familiarize you with all of these items. Figure 2.1 illustrates two (2) N2-X Ethernet Extender terminals in a point-to-point configuration.

The data signal and the AC/DC supply voltage are connected to the ODU by means of a power/data cable assembly. The supply voltage passes through a bridge rectifier to a DC to DC converter. The output of this converter is +15V. This +15V supply drives three DC regulators within the ODU. One regulator provides -5 VDC, the second 11 VDC and the third being a dual output type supplies +5 and +5.8 volts. The FPGA coder interleaves and scrambles the TTL data from the coder. The FPGA is programmed to output the data at 4 times the input rate (6.176 MHz for the DS1 rate or 8.192 MHz for E1 rates). This provides a data rate which is optimal with respect to the FCC rules for spectral power densities defined for this frequency allocation. The data is passed through a 7th order low pass filter to reduce unwanted high frequency signal images prior to modulation. A double balanced mixer is used to modulate the data signal on to a CW signal provided by the synthesizer at the desired output frequency. The output of the mixer contains the BPSK modulated signal at the desired frequency. A high pass filter eliminates spurious noise, rejects harmonic images and insures that the proper bandwidth is maintained prior to being amplified. The RF output section consists of three main components: a RF driver amplifier, a logic controlled switch attenuator and a RF power amplifier. The driver amplifier provides the first stage of RF amplification, the switch attenuator serves a dual purpose. The first is to provide a customer selectable 6 dB attenuator to reduce output power when needed. Secondly, this circuit acts as an RF impedance matching network between the driver and power amplifier gain stages. The power amplifier provides the amplification required prior to being output through a diplexing filter and ultimately to the antenna. 16 DeCoder TTL Clock/Data TTL 17 85.12 MHz BPSK Demodulator I&Q Bit Synchronizer -6.176 to -8.192 Data Output Level Converter Data Input FPGA Coder Loader 85.12 MHz Dual Synthesizer RSSI IF Section Synthesizer TcXo 19.2 MHz ÷2 PROM BPSK Modulator 2nd Down Converter 389.76 MHz Low Pass Filter DIP Switch 6.176 Mb/s for T1 8.192 Mb/s for E1 MMIC AMP 5.3/5.7 GHz Driver 474.880 MHz High Pass Filter 1st Down Converter -6 dB Switch Attn.

At the antenna, the received BPSK modulated signal from the opposite terminal is passed through a diplexing filter which is used to isolate the incoming signal from the transmitter output and to bandpass filter the received signal thereby reducing the chance of unwanted signal products from entering the receiver. A low noise amplifier (LNA) detects and amplifies the signal bandpass filter on the output of the LNA provides band limiting of the received spectrum to reject unwanted signal products. The first downconverter combines a CW signal at the receiver frequency from the synthesizer and the incoming signal by means of a mixer to produce the first IF product at 474.880 MHz. A 75 MHz bandpass filter limits the possibility of unwanted out of band products from entering the 2nd IF. The first IF is amplified by a MMIC device and is downconverted by mixer a 389.76 MHz signal from the synthesizer with the 474.880 MHz 1st IF signal. The result is a 85.12 MHz 2nd IF product which is bandpass filtered and fed to an RSSI IF processing DC which derives an RSSI voltage used to determine signal strength. A BPSK demodulator places the 85.12 MHz 2nd IF and 85.12 MHz varactor diode source out of phase. The resultant product is a DC level I and Q signal of which only the I signal is input to the Bit Synchronizer to re-clock the data. The re-clocked data is decoded and output at TTL level to the DS1/E1 level converter which outputs the data in AMI, B8ZS or HDB3 format as needed. The data is interconnected to the TU and output on the front panel by means of RJ48C or BNC connector depending on the data format being used. 2.6.3 Synthesizer The FPGA provides four 22-bit streams in a serial format loaded to the synthesizer. This data provides all of the possible frequencies at which the system can operate. Depending upon the dip switch settings selected, the actual frequency being used is selected. When the reset button is pressed, the FPGA will reload this data to the synthesizer. The PROM contains all of the possible frequency combinations. 18 N2-X Ethernet Extender Installation and Operation Manual 3.0 Equipment Installation and Commissioning 3.1 Installation The N2-X Ethernet Extender has been specifically designed for ease of installation.

If the LED is Off, refer to the Maintenance and Troubleshooting section of the manual. Refer to Table 3.2. 3.5.1 Configuring N2-X Ethernet Extender System Antennas The antennas used on an N2-X Ethernet Extender radio system are generally configurable for either vertical or horizontal polarization. It is extremely important to verify that both antennas are configured for the same polarization, and that the appropriate antenna polarization has been selected for the specific radio link. Table 3.2 - Installation Checklist Installation Checklist Is the rack mounting hardware secure? Is the unit properly grounded? Is the antenna properly connected? Are the data connections in place and correct? Is the Power LED On? WL035915 26 N2-X Ethernet Extender Installation and Operation Manual 3.5.2 Aligning the N2-X Ethernet Extender System Antennas With the N2-X Ethernet Extender at each site properly configured for operation, antenna alignment must be performed at both sites. Proper antenna alignment is crucial to the proper operation of an N2-X Ethernet Extender radio system, and should only be accomplished by experienced professionals. The N2-X Ethernet Extender is equipped with a ODU mounted BNC-(f) Link Test connector to which an analog or digital voltmeter can be connected. The voltage range at the test point, between the center conductor of the connector and ground, varies from approximately two VDC to four VDC, serving as a receive signal strength indicator (RSSI). The stronger the receive signal, the higher the RSSI voltage. Emanating from a microwave antenna is a main beam (or lobe) of RF energy, surrounded by RF side lobes. The beamwidth of the main beam varies with the size and type of antenna, as well as the specific frequency of the RF signal, and is generally defined by the nominal total width of the main beam at the half-power (-3 dB) points. Side lobes surround the main beam at specific angle distances, and will be lower in power than the main beam. When aligning an antenna system, it is extremely important to verify that the antennas are both aligned on the main beam, not on a side lobe. Referencing Table 3.3, the first side lobe will generally be located at an angle slightly less than twice the antenna beamwidth. Following the course alignment of an antenna system, a common practice when performing a fine alignment is to slowly swing each antenna (one at a time!) in both vertical (elevation) and horizontal (azimuth) planes to verify that the main beam and first side lobe can be accurately identified. This insures that accurate alignment of the antenna system on the main beam has been accomplished. Each N2-X Ethernet Extender is shipped with an RSSI test sheet, showing the relationship between the receive signal strength level (in dBm) and the RSSI level (in VDC). These RSSI test sheets are often referred to as AGC Curves. The RSSI test sheets can be used to verify that the calculated receive signal levels match up with the actual receive signal levels. Substantial differences between calculated and actual levels could point to transmission system problems, side lobe alignment, path obstructions, etc. Table 3.3 - Approximation Table Antenna Diameter and Style Gain (dBi) 3 dB Beamwidth (degrees) 1st Side Lobe, Maximum (degrees) 2nd Side Lobe, Maximum (degrees) 2-foot parabolic 4-foot parabolic WL035916 27 N2-X Ethernet Extender Installation and Operation Manual 28 N2-X Ethermet Extender Installation and Operation Manual 4.0 Maintenance and Troubleshooting The N2-X Ethernet Extender contains static sensitive components, and has no user-serviceable parts. 4.1 N2-X Ethernet Extender Maintenance The N2-X Ethernet Extender is designed to operate with no scheduled maintenance activities. From a precautionary perspective, a regular check of power supply input voltages and RSSI voltages should be planned by the user. 4.1.1 RSSI Voltage The Wireless Customer Service department recommends a monthly check of the N2-X Ethernet Extender’s RSSI voltage. Variations in the RSSI voltage could be an indicator of antenna or antenna feed movement, loose or improper RF cabling or connectorization, path obstructions or reflections, etc. 29 N2-X Ethernet Extender Installation and Operation Manual 4.2 Identifying and Resolving Receive Signal Strength Issues There are a great number of items which can affect the transmission of a microwave signal from one site to another. Every microwave path is unique, and must be evaluated for performance before a radio link is installed. Outside of radio equipment issues, antenna alignment, RF signal blockage, and multipath fading are among the most common transmission problems experienced in the field. 4.2.1 N2-X Ethernet Extender Equipment Issues Frequency Selection 1. Verify the transmit/receive frequency selection for each N2-X Ethernet Extender radio is set appropriately, and that a “matched pair” of radios has been selected for the system. Each N2-X Ethernet Extender terminal can be set to the frequencies listed in Table 4.1. 2. To reduce the possibility of co -adjacent channel interference, proper frequency coordination and antenna polarization is used to isolate each channel. The concept is to achieve maximum RF isolation between link channels by means of frequency spacing and antenna polarization. In a “star” configuration an optimum frequency and antenna polarization plan is provided to demonstrate an example of maximum isolation between links (See Figure 4.1).

Before making switch changes, verify the version of the Digital Board in use. In a working system, the East Radio might be equipped with Version one while the West Radio might be equipped with Version two. The specific version of a N2-X Ethernet Extender’s Digital Board will have no effect on the operation of a radio system. In addition to there being two versions of the Digital Board, there are also two types of Digital Boards: a X Mb/s type and a X Mb/s type. Each type of Digital Board contains different components. 4.3.1 Digital Board Version One This Board does not have a white silkscreen of the Wireless, Inc. logo above the board number designation 019-XXXXXX-001.

Carefully unpack the reflector, mount, shroud (if any), radome (if any) and feed from the crate. For correct antenna performance, handle all components with care. Set aside the packaged feed and any shroud or radome. See Figures B.3 through B.6. Caution: The reflector spinning has been formed to a very close-toleranced parabolic shape. Careful handling and assembly is required to avoid denting or deforming the reflector, which would degrade the antenna's performance. 2. Inspect for any damaged parts. See Tables B.2a-B.2d for an inventory of the parts and hardware shipped with the antenna. Shroud Attachment Attach the shroud assembly that is provided with high-performance antennas to the reflector. The installation procedure is covered by another instruction sheet supplied with the shroud. Note: Some models have the shroud factory installed.

Azimuth Adjustment Clamp/Shear Stop Installation 1. Verify proper assembly of the azimuth clamp/shear stop clamp as shown in Figure B.15 and B.16. Securely attach the shear stop clamp to the mast pipe as shown, orienting it as nearly as possible to the antenna boresight direction, and square to the mast axis. Note that the shear stop clamp used on the two foot antennas also provides the azimuth adjustment. 2. Refer to Figure B.1 for the position of the antenna centerline relative to the shear stop clamp. The clamp must be mounted to provide support during installation and azimuth adjustment. Figure B.15 - Azimuth Clamp/Shear Stop Assembly 3/8” (10mm) Round Head Screw Lockwasher and Nut (4) ø 2.4” - 4.5” (60-115mm) WL035946 Figure B.16- Azimuth Adjustment Clamp Assembly WL035947 B-14 N2-X Ethernet Extender Installation and Operation Manual Antenna Hoisting and Installation 1. Attach a hoist strap around the vertical assembly or the horizontal assembly as shown in Figure B.17. Do not hoist by the elevation rod. Make sure that the vertical assembly is unobstructed where it will mount against the mast pipe. 2. Attach tag lines and carefully lift the antenna into position, resting the vertical assembly on the shear stop clamp. 3. Fasten the mount to the mast pipe with 1/2” U-bolts. The antenna must be free to rotate during azimuth adjustment, so tighten only enough to close the gap between the mast and vertical channel. Do not leave the antenna loose for any extended period of time, i.e. overnight. Figure B.17- Hoisting the Antenna 5” (127mm) WL035948 B-15 N2-X Ethernet Extender Installation and Operation Manual General Antenna Alignment Procedures Normally the antenna is aligned by performing azimuth and elevation adjustments and elevation adjustments as necessary until the peak signal is obtained. It may be helpful to repeak one adjustment before finalizing or locking down the other. See Figure B.18. Warning: Damage to the antenna can occur if azimuth or elevation adjustments are attempted without loosening the proper connections as described in the following steps. Azimuth Adjustment 1. Be sure the mast pipe U-bolts are just loose enough to allow mount rotation while maintaining complete contact between the mount and the mast pipe. 2. Turn the long stainless steel azimuth screws against the mounting channel. By alternately turning one azimuth adjustment screw out and the other in, the antenna can be rotated to the desired azimuth angle. Approximately 1 turn changes the azimuth direction by 1°. Avoid adjusting the antenna beyond the ±5° provided by the azimuth clamp as this can damage the adjusting hardware. Fasten the antenna to the mast pipe and reposition the clamp if needed. Note: By securing the mount to the mast pipe and realigning the azimuth clamp with the antenna boresight, more reliable and precise azimuth adjustments can be achieved. After all adjustments are made, tighten both of the azimuth screws against the channel and secure with the lock nuts provided. 3. Tighten the mast pipe U-bolts while maintaining the peak signal by alternating from left to right in 1/4 turn intervals. Figure B.18 - Antenna Alignment using RSL Output while Adjusting the Antenna WL035949 B-16 N2-X Ethernet Extender Installation and Operation Manual Elevation Adjustment 1. Insure that both of the bolts connecting the mount to the Top Support Angles and the pivoting Elevation Angle (refer to Figures B.7 and B.9) are just loose enough to allow resisted rotation. See Figure B.18. 2. Back the outer nuts on the elevation rod away from the bottom mount plate to allow some fine adjustment range. 3. Turn the inside nut (with flat washer) on the elevation rod to adjust the elevation angle. Approximately 5 turns changes the elevation by 1°. Remember, for elevation greater than 20°, install the two beveled washers as shown in Figure B.9. 4. After all adjustments are made, lock the nut against the bottom mount plate. Tighten the angle pivot bolt and support bracket bolts. Important: Be sure to tighten all hardware after final adjustments and insure that split lockwashers, palnuts, or jam nuts are used where provided. B-17 N2-X Ethernet Extender Installation and Operation Manual Inspection and Maintenance 1. Before leaving the installation, check that all hardware on the mount, shroud, radome, and feed is tight and that nuts are locked in place. 2. Inspection of the antenna should be performed at lease once a year to check its condition and to insure safe operation and maintenance. Qualified personnel, knowledgeable and experienced in antenna installations, are required for this inspection. Supplemental Information Table B.3 is provided for installers unfamiliar with adequate nut tightening procedures for use on stainless steel bolts, U-bolts, galvanized bolts or any bolts without the ASTM-”A325” marking on the head. Disregard these recommendations when specific tightening requirements are given. Note: It is not recommended to reuse a palnut that has already been fully tightened or deformed in any way. It should be replaced by a new palnut. Weather Proofing the Type N Female Connector on Feeds Remove the protective cover from the end of the feed and mate the connectors, screwing the male connector firmly onto the feed. Important: After connecting the coaxial cable, wrap the Type N connector with the gray butyl rubber, squeezing it firmly around all joints to make a continuous seal. Finish the weatherproofing by wrapping the butyl rubber with several layers of black PVC tape (not supplied).

Continue alternating slots and prying in either direction until desired alignment is obtained. Lock down hardware securely before leaving the site. Figure C.3- Azimuth and Elevation Planning Top View Top View Sectional View Sectional View WL035953 C-3 N2-X Ethernet Extender Installation and Operation Manual Attach the antenna to the mount as shown in Figure C.4. For antenna polarization, assemble the antenna to the mount using four sets of nuts and washers after desired polarization is selected. In horizontal polarization the arrow sticker should be pointed in a horizontal direction. Likewise, in vertical polarization the arrow sticker should be pointed in a vertical position. Important: After cable connection is completed, wrap connection with Butyl or other waterproof tape, supplied by the customer. Each panel antenna has four factory sealed drain holes located on the back of the antenna. After orienting the antenna to its proper polarization, the lower most sealed drain hole(s) must be punctured with a pointed tool. See Figure C.4. Caution: Do not allow the tool to protrude into the drain hole more than 1/4” (7mm) or damage to the antenna may result.
