:ll!:llli £1SC & January 15, 2014 Correspondence Reference Number: 45059 FCC I.D. : LDK102089P Form 731 Confirmation: EA351549 Mr. Rodriguez, In response to your email inquiry of 13Jan2014; 1) The PSD and correlated gain is computed according to 662911 DO1 Multiple Transmitter Output vO2; page 9 (i) If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where Array Gain is as follows. * For power spectral density (PSD) measurements on all devices, Array Gain = 10 log(NANT/NSS) dB. In our case; 14 dbi (directional) + 10log(2) = 17dB 2) * For power measurements on IEEE 802.11 devices, 1,2 Array Gain = 0 dB (i.e., no array gain) for NANT § 4; Array Gain = 0 dB (i.e., no array gain) for channel widths > 40 MHz for any Nant. ud Chiller EMC Compliance Eng.
