viiN2-4XE1 Installation and Operation ManualMicrowave Antenna Radiation WarningDesigned for point-to-point operation,an N2-4XE1 microwave radio system will use directionalantennas to transmit and receive microwave signals.These directional antennas are usuallycircular or rectangular n shape,are generally located outdoors,and are usually mounted on atower or mast.Referencing OET Bulletin 65 (Edition 97-01,August 1997)from the Federal CommunicationCommission ’s Office of Engineering &Technology,limits for maximum permissible exposure(MPE)to microwave signals have been adopted by the FCC for both Occupational/Controlledenvironments 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 powerdensity of its transmitted microwave signal.Unless you are very close,however,microwaveexposure levels will fall far below the MPE limits.To determine how close to a microwaveantenna you can be and still remain below the MPE limits noted above,“worst case ”predictionsof the field strength and power density levels in the vicinity of an N2-4XE1 ™ microwaveantennacan be made from the following calculations.The equation is generally accurate in the far-fieldof an antenna,and will over-predict power density n the near-field (i.e.close to the antenna).S =PG/4 π R2where: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 isotropicradiatorR =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 mustbe converted using the following equation:G =10dB/10In order to satisfy FCC RF ezposure requirements, the antennas used with this product must beinstalled in such a way as to insure a minum separation distance between the antennas and allpersons of the amounts shown in the table below:RF Exposure Safety InformationMax RF Power TX Antenna Uncontrolled Environment Controlled MPE 1 mW/cm2P, dBm G, dBi MPE 1 mW/cm2 MPE 5 mW/cm2
