28 Intentional Radiators Criteria for Intentional Radiators Antenna Requirement Test Requirement: : An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. The structure and application of the EUT were analyzed to determine compliance with Section of the Rules. Section states that the subject device must meet at least one of the following criteria: a.) Antenna must be permanently attached to the unit. b.) Antenna must use a unique type of connector to attach to the EUT. c.) Unit must be professionally installed. Installer shall be responsible for verifying that the correct antenna is employed with the unit. Results: Test Engineer(s): The EUT as tested is compliant the criteria of The antenna is professionally installed. The EUT uses a 23 dbi Panel antenna for P2P.

29 Intentional Radiators Criteria for Intentional Radiators (a) Conducted Emissions Limits Test Requirement(s): (a): For an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 150 khz to 30MHz, shall not exceed the limits in the following table, as measured using a 50 H/50 line impedance stabilization network (LISN). Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the boundary between the frequency ranges. Frequency range (MHz) (a), Conducted Limit (db V) Quasi-Peak Average * Table 13. Conducted Limits for Intentional Radiators from FCC Part (a) Test Procedure: The EUT was placed on a 0.8 m-high wooden table inside a screen room. The EUT was situated such that the back of the EUT was 0.4 m from one wall of the vertical ground plane, and the remaining sides of the EUT were no closer than 0.8 m from any other conductive surface. The EUT was powered from a 50 /50 H Line Impedance Stabilization Network (LISN). The EMC receiver scanned the frequency range from 150 khz to 30 MHz. Conducted Emissions measurements were made in accordance with ANSI C "Methods and Measurements of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40 GHz". The measurements were performed over the frequency range of 0.15 MHz to 30 MHz using a 50 /50 H LISN as the input transducer to an EMC/field intensity meter. For the purpose of this testing, the transmitter was turned on. Scans were performed with the transmitter on. Test Results: Test Engineer(s): The EUT was compliant with this requirement. Measured emissions were below applicable limits. Prescans were made on low, mid and high channels. They showed that the emissions profile and amplitudes were similar. Therefore, final measurements were only made on channel 5785 MHz. Dusmantha Tennakoon Test Date(s): 02/10/11 MET Report: EMC83056-FCC , MET Laboratories, Inc. Page 21 of 53

Output Power Requirements from (b) (c): if transmitting antennas of directional gain greater than 6 dbi are used the peak output power from the intentional radiator shall be reduced below the stated values in the Table 16, as appropriate, by the amount in db that the directional gain of the antenna exceeds 6 dbi. Systems operating in the MHz band and using a point to point application may employ transmitting antennas with directional gain greater than 6 dbi provided the maximum peak output power of the intentional radiator is reduced by 1 db for every 3 db that the directional gain of the antenna exceeds 6 dbi. Systems operating in the MHz band that are used exclusively for fixed, point-topoint operations may employ transmitting antennas with directional gain greater than 6 dbi without any corresponding reduction in transmitter peak output power. Fixed, point-to-point operation excludes the use of point-to-multipoint systems, Omnidirectional applications, and multiple co-located intentional radiators transmitting the same information. The operator of the spread spectrum intentional radiator or, if the equipment is professionally installed, the installer is responsible for ensuring that the system is used exclusively for fixed, point-to-point operations. The instruction manual furnished with the intentional radiator shall contain language in the installation instructions informing the operator and the installer of this responsibility. Test Procedure: Test Results: Test Engineer(s): The transmitter was connected to a calibrated spectrum analyzer. The EUT was measured at the low, mid and high channels of each band at the maximum power level. The EUT was compliant with the Peak Power Output limits of (b).

39 Intentional Radiators Criteria for Intentional Radiators (d) Radiated Spurious Emissions Requirements Test Requirements: (d); : Emissions outside the frequency band (d): In any 100 khz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 db below that in the 100 khz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement. Attenuation below the general limits specified in (a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in (a), must also comply with the radiated emission limits specified in (a) (a): Except as shown in paragraph (d) of this section, only spurious emissions are permitted in any of the frequency bands listed below: MHz MHz MHz GHz ( 2 ) Table 18.

40 Intentional Radiators Test Requirement(s): (a): Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in Table 19. Frequency (MHz) (a),Radiated Emission Limits (db 3m Above Table 19. Radiated Emissions Limits Calculated from FCC Part 15, (a) Test Procedures: Test Results: Test Engineer(s): The transmitter was turned on. Measurements were performed of the low, mid and high Channels. The EUT was rotated orthogonally through all three axes. Plots shown are corrected for both antenna correction factor and distance and compared to a 3 m limit line. Only noise floor was measured above 18 GHz. The EUT was compliant with the Radiated Spurious Emission limits of (d). Emissions below 1 GHz that appear to be above the limit on plots 16, 17 and 18 are from the digital portion of the EUT and therefore do not fall under the limits.

49 Intentional Radiators Criteria for Intentional Radiators (i) Maximum Permissible Exposure RF Exposure Requirements: RF Radiation Exposure Limit: (b)(1) and (b)(2): Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission s guidelines : As specified in this section, the Maximum Permissible Exposure (MPE) Limit shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec (b), except in the case of portable devices which shall be evaluated according to the provisions of Sec of this chapter. Test Results: The EUT was compliant with the requirements of this section. MPE Limit Calculation: EUT s operating frequency is MHz;. Highest conducted power = mw (i.e dbm). Therefore, Limit for Uncontrolled exposure: 1 mw/cm 2. Equation from page 18 of OET 65, Edition S = P G/ 4 R 2 where, S = Power Density mw/m 2 P = Power (mw) R = Distance to the center of radiation of the antenna G = Maximum antenna gain Maximum antenna gain for EUT = 23 dbi = P = mw S = 1 mw/ cm 2 G = R = sqrt {467.7*199.5 / 4( )(1)} R = 86.2 cm Therefore, EUT meets the Uncontrolled Exposure limit at 86.2 cm.
