Wireless Inc. FCC ID: EV9N2-4XE1-5G711 of 16SUMMARY OF TEST RESULTS15.407 General Technical RequirementsThe UNII requirements for maximum power, peak power spectral density, minimum26 dB emissions bandwidth, and maximum EIRP are interdependent variables. Inaddition, the level of transmitter spectral re-growth at the UNII band edges will limit thepower 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 11.4 MHz.A number of antennas can be used with the point-to-point UNII radio, with gains thatvarybetween 18.5 dBi and 28.5 dBi.15.407(a)3 Power limits17 dBm + 10 log (11.4) = 27.2 dBm max. for 5.725 - 5.825 GHZ bandPeak power spectral density: = 17 dBm/MHzDefacto EIRP limit: 27.2 dBm + 23 dBi = 50.2 dBm EIRPMaximum Power, dBm, into antenna23 dBiMti Panel 18 dBiGabriel panel 26 dBiRadiowaves dish 28.5dBiGabriel dishfo MHz Max P, dBm Max P, dBm Max P, dBm Max P, dBm5807.3 4* 12 4* 0*5733.6 12 12 12 8all others 12 12 12 8* limited by EIRP restrictions in 15.407(b)2

Wireless Inc. FCC ID: EV9N2-4XE1-5G716 of 16Test MethodWith the transmitter operating at full power, the EUT was rotated 360° and the searchantenna was raised and lowered in both polarities, all in an attempt to maximize thelevels of the received emission for each harmonic and spurious emission up to 40 GHz.Test ResultsNo emissions above instrumentation noise floor were detected. Tests were performed foreach of the 4 antennas at a LOW, MID, and HIGH channel.Antenna conducted measurements confirmed there are no harmonic emissions generatedby this transmitter above the noise floor of the spectrum analyzer (-51 dBm or lower).Using the relationship between field strength, output power and distanceEV/m = (•(30*PW*G))/d meters (E volts/m, P watts, G numeric gain over isotropic)Assuming G=1, converting volts to microvolts and watts to milliwatts, simplifying and combiningterms, and using a distance of d = 3mE@3m, dBuV/m = (95.24 + PdBm) dBuV/m = 95.24- 51dBm = 44.24 dBuV/m!5.205, 15.209 limit: 54 dBuV/m @ 3m
