These models are Masters AAG1M25X, AAG1M36X, AAG1M58X Slaves AAG1S25X, AAG1S36X, AAG1S58X The difference between master and slave units is in the additional GPS module and GPS antenna installed inside the master radios of AbsoluteAir product family. Because the additional GPS circuitry, from the point of view FCC Part 15 unintentional radiation and conducted emission tests, the master units have one more clock source and present the worst case scenario. Everything else between master and slave product is 100% the same; both master and slave radios have the same enclosures, the same digital, RF boards and the same antennas. Between different frequency bands (2.5, 3.6 and 5.8 GHZ) models - all ports of the digital boards are 100% the same - Digital boards use the same fabs and almost identical assemblies using exactly the same clock signals. - The clock signals at RF boards are also 100% identical. - The only difference between of 2.5, 3.6, 5.8 GHZ models is the RF / Calibration circuitry and we believe that band related differences have no impact on FCC Part 15 test results.

Calculation of Power Density on Antenna Panel Surface •In our case, the Tx power is: –Pout/PA = 23.6dBm max = 0.23W –Number of PAs = 16 –Total power during Transmit = 35.6dBm = 3.7W –For a 67% Tx duty cycle, the average Tx power = 33.9dBm = 2.4W •The antenna area is: –Antenna size is 10.5 inches x 18.2 inches. –Area = 191 in 2 = 1233 cm 2 •The antenna and feed losses are 2.1dB (from PA output to antenna element) –The effective average transmit power at the elements is 31.8dBm = 1.5W •The power density on the antenna panel surface using S=4*P/A is: –Power density = 4.89mW/cm 2 –The calculation uses the S=4*P/A equation to compute the power density on the surface of an aperture antenna as given in OET Bulletin 65. –The power density is below the FCC limit for occupational/controlled exposure on the antenna panel surface. 1
