EV9N2-4XE1-5G3Point to Point Transceiver

vii N2-4XE1 Installation and Operation Manual Microwave Antenna Radiation Warning Designed for point-to-point operation,an N2-4XE1 microwave radio system will use directional antennas to transmit and receive microwave signals.These directional antennas are usually circular or rectangular n 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/cm2 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 re main below the MPE limits noted above,“worst case ”predictions of the field strength and power density levels in the vicinity of an N2-4XE1 ™ 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 n the near-field (i.e.close to the antenna). S = P G/4 π R2 where: S =power density (in mW/cm2) P =power input to the antenna (mW) G =power gain of the antenna in the direction of nterest 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 In order to satisfy FCC RF ezposure requirements, the antennas used with this product must be installed in such a way as to insure a minum separation distance between the antennas and all persons of the amounts shown in the table below: RF Exposure Safety Information Max RF Power TX Antenna Uncontrolled Environment Controlled MPE 1 mW/cm2 P, dBmG, dBi MPE 1 mW/cm2 MPE 5 mW/cm2 P, dBmG, dBi Safe Distance, cm Safe Distance, cm 12.018.0 20* 20* 12.023.0 20* 20* 12.026.0 22.4 20* 12.028.5 29.9 20* * For fixed and mobile antenna installations, FCC requires a minimum separation distance of 20 cm, regardless of whether calculations would indicate a lesser distance. 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 N2-4XE1 ™ microwave signal radiation,please contact the Wireless,Inc.

To:Thomas Cokenias, T.N. Cokenias Consulting From:Joe Dichoso [email protected] FCC Application Processing Branch Re:FCC ID EV9N2-4XE1-5G3 Applicant:Wireless Inc Correspondence Reference Number: 13451 731 Confirmation Number:EA96901 Date of Original E-Mail:04/13/2000 Place your reply in the RF exposure info folder. Send a separate correspondence letter from any previous request. This is a 5.25-5.35 GHz UNII tx, 15.8 mW listed. Still waiting on the user's manual. Re RF Exposure, please ask the following: 1. The antenna gain list in Exhibit 6 does not match that in the manual submitted for EA 96902 (assuming the same manual is used for both products). Please address. ANS1: New pages have been added to the manual used for these products. A new page vii has the correct wording for RF safety, along with a table of MPE distances vs antenna used. The new page 8 has a revised antenna list to include all those that were tested. The list in the manual includes antennas not tested - the 34 dBi antenna for export only, and a dual polarized dish with the same gain as the single polarized dish that was tested. 2. Please be sure the language in the manual complies with the requests made in reference to EA 96902. ANS2: Refer to revised page vii submitted as separate attachment

In addition, the level of transmitter spectral re-growth at the UNII band edges will limit the power output that may be transmitted into a particular antenna, since the emission limit is -17dBm/MHz and /or -27dBm/MHz EIRP, dependent on both antenna gain and power input. The Wireless UNII radio has user programmable output power levels from 0 - 12 dBm. The 26 dB channel bandwidth is 11.7 MHz. A number of antennas can be used with the point-to-point UNII radio, with gains that vary between 18.5 dBi and 34 dBi. 15.407(a)3 Power limits 11 dBm + 10 log (11.7) = 21.7 dBm max. for 5.25 - 5.35 GHZ band Peak power spectral density: = 11 dBm/MHz Defacto EIRP limit: 21.7 dBm + 6 dBi = 27.7 dBm EIRP Maximum Power, dBm, into antenna 23 dBi Mti Panel 18 dBi Gabriel panel 26 dBi Radiowaves dish 28.5dBi Gabriel dish fo MHzMax P, dBmMax P, dBmMax P, dBmMax P, dBm 57394 pre-set8 pre-set0 pre-set-1 using ext. atten 5736480-1 5733480-1 Wireless Inc.FCC ID: EV9N2-4XE1-5G3 12 of 31 RF Output Power Measurements Ref: 15.407(a)2 Measure…
