Ensemble Communications Inc. Planning a System Deployment2-11 Frame Synchronization When a signal is attenuated by rain, the CPE increases its power to boost the signal transmitted to its base station. In such cases, this power boost allows the signal to reach other base stations, especially if there is no rain in the path between the CPE and the other base stations. Base station-to-CPE synchronization within a cluster of cells can reduce this type of interference. RF Exposure Guidelines NoteRefer to the FCC Office of Engineering and Technology Bulletin No. 65 for RF exposure guidelines.

Ground MastAll steel mounting structures attached to the building and the antenna mast must be connected to the building grounding system. If no grounding system or ring is available, ground the antenna mounting structures to the nearest structural beam. The grounding conductor should be set at least a # 2 (AWG) solid tinned copper wire. Use exothermic welds (Cad Welds) when possible to connect to the mounting structure and the building grounding system. Antenna Mounting1. Attach the ODU mounting bracket to a mast between 2- and 4- inches in diameter (1 in Figure 6-1). 2. Remove the nuts and washers (2 in Figure 6-1) from one side of each of the two mounting clamps (3) and slide the mounting clamps off the bolts. Set them aside in a safe place. 3. Slip the mounting rack (4 in Figure 6-1) around the mast. 4. Reattach each of the two mounting clamps with the flat washer, lock washer, and nut. 5. Tighten with a 1/2-inch socket wrench until secure. Ensemble Communications Inc. CPE Site Setup6-5 Figure 6-1. CPE Pole Mount Assembly 6. Attach the antenna to the mounting plate, orienting it for proper polarization (see the next sections) and LOS alignment with the base stations. 7. After aligning the antenna, tighten the mounting clamps. Lightning Suppressor Installation NoteA lightning suppressor is not shipped with the ODU. See page 3-10 for the Ensemble-recommended lightning suppressor. WARNING It is not possible to guarantee that lightning protection will be 100 percent effective against a direct lightning strike. Install one suppressor as close as possible to the point at which the cable enters the building. Another suppressor should be installed as close as possible to the ODU. See Figure 6-2 and Figure 6-3 for illustrations of the suppressor installation.

Ensemble Communications Inc. CPE Site Setup 6- CPE Indoor Installation Indoor Equipment Placement The Fiberless 320 CPE can be located in a wiring closet with other communications equipment or in a customer suite. Its compact low-profile package, rubber feet, and optional mounting brackets make it easy to mount it in either a standard 19-inch or 23-inch cabinet or stack on a shelf. CPE Indoor Access Requirement Allow enough room to accommodate the size of the unit (1.5 inches high by 9.5 inches deep) with enough clearance to accommodate termination of up to 16 data cables or 12 T1 cables, two cables to the ODU, and a power cord. CPE Indoor Temperature The location should meet these temperature allowances, including enough ventilation to dissipate heat loads of 150 Watts: 10° to 30° C (50° to 86° F) CPE Indoor PowerThe CPE indoor unit is normally shipped for use with 120 VAC power. When possible, it should be plugged into a dedicated 15 Amp circuit. You may install a small PC-style UPS if desired. CPE Indoor GroundingFor AC systems, ground the indoor unit by connecting its conductor to a grounded power outlet. The ground conductor on the power plug must be connected to the building’s electrical ground. WARNING Do not power up the indoor unit until you are instructed to do so during the initial procedure. CPE Indoor Procedure•Select an environment that is dirt and dust free for the CPE. •Situate the CPE box in a rack, shelf mount or on a table top. Connect the power cable to the power connector on the back of the CPE indoor equipment. Ensemble Communications Inc. 6-10Operator’s Guide to the Fiberless System WARNING The cable may have -48 VDC across the connector when connected to the CPE. Therefore, DO NOT apply power to the CPE before connecting or disconnecting the RG-6 cable at either end. NoteThe CPE requires a nominal of 110/220 VAC, 10 Amps. Each CPE requires a separate circuit breaker. UPS is optional. •Connect the RG-6 cable to the CPE ODU1 port connector (see Figure 6-6). •Plug the CPE power cord into a 110 VAC power outlet as shown in the Figure 6-6. •Turn on breaker to the CPE and verify that the fan is operating. NoteThe CPE has a field-replaceable 3-Amp fuse located behind the switch housing. Remove the housing to replace this fuse. Figure 6-6. Power Cable Installation Caution If you power off the CPE, wait five seconds before turning on the power again. $" ;)8%-2

The minimum separation distance was determined using calculations. They were done using FCC OST/OET Bulletin 65 (“Evaluating Compliance with FCC Specified Guidelines for Human Exposure to Radiofrequency Radiation”). The aperture antenna equations for predicting RF fields from that document were used. They yielded the following results: Power Density At the surface of the antenna 1.008 mW/cm 2 (OST/OET Bulletin 65, equation 11) In the near field (R < 2.5m): 0.458 mW/cm 2 (equations 12, 13 & 14) In the transition region (2.5m < R < 6m): 0.191 mW/cm 2 (equations 16 & 17) In the far field (R < 6m): 0.196 mW/cm 2 (equation 18) Antenna Information Frequency 27.5-29.5 GHz Frequency Band LMDS A Band Gain 35.8 dBi, minimum Polarity Linearly polarized (H/V) Beam Width (azimuth) Beam Width (elevation) 2.2° mimimum 2.2° mimimum Cross-polarization discrimination > 30.0 dB Diameter 12.5” (31.75 cm) The FCC General Population limit is 1 mW/cm 2 , hence the use of 0 cm as the minimum separation limit. A drawing of the radiation warning label and a picture of its location has been submitted. The file names are: ODU_RFlabel.pdf and ODU_RFlabel_location.pdf.
