862-01545 μ Link System Manual Issue 1 Page 26.1 Outdoor Unit Power Levels Follow these steps to set the transmitted power level onthe OU. Refer to table 4 for transmitted power levels. Step Action 1. Determine the gain of the antenna, A T , to be installed with the OU. 2. Calculate the transmitted power, P T , according to the following formula:P T = 30dBm – (A T – 6)/3 dBm 3. Determine the power level to be used in NMSby consulting table 4. 4. Install a fixed attenuator between the OU andthe antenna if the power level can not besufficiently reduced. 5. Set the transmitted power level in NMS. 6. Repeat for both stations. Example: Determining the transmitted power level. Step Action 1. Install a 24dBi antenna. 2. Transmitted power level to be used is:PT = 30 dBm – (24-6)/3 dBm = 30 dBm – 6 dBm = 24 dBm 3. Power level 5 corresponds to 24 dBmtransmitted power (from table 4). 4. Ste the power level to level 5 in NMS. μ Link System Manual 862-01545 Page 26.2 Issue 1 Table 1. Transmitted Power Level Setting NMS PowerLevel Setting Transmitted Power (dBm) 120221322423524625726

I’ve been told that the transmitter schematics and block diagram have been sent to you from Aironet. B. I’ve sent photographs of both sides of the circuit boards; the shielding has been removed. C. I’ve sent a new confidential request letter from the applicant. It is not necessary for the block diagram to be confidential; only the schematics need to be confidential. D. The antennas to be used are: YAGI ANTENNA MAKE: CUSHCRAFT MODEL: PC2415N GAIN: 17dBi PARABOLIC ANTENNA MAKE: CALIFORNIA AMPLIFIER MODEL: 130094-1 GAIN: 24 dBi E. OTUPT POWER – This is an error. The output power should be 450 mW. F. I’ve sent the Process Gain measurement report. G. I’ve also sent additional radiated measurements. Should you have any questions or require any further information, please let us know. Regards, Sharon Hoffman/TIMCO ENGINEERING, INC. SAH/hs

In order to comply with the 250milliWatt limit with the 24dBi antenna gain the power output was changed and the UUT remeasured. The power measured 0.220Watts. This is a request for you to correct the 731 form. 2. The power output limit with the 24dBi antenna is 0.250Watts, and for the 17dBi antenna would be 0.4Watts but since the transmitter is the same they supplied a 0.22Watts Unit, sorry I over looked this. 3. The original radiated measurements were made with a video bandwidth of 300kHz, NOT 10Hz as stated in my report. Attached are new measurements that were made with 1.0MHz RBW = VBW. 4. The field strength of the starting edge of the restricted band is included in the radiated measurements. I will include this measurement in all future reports. Thanks for your help.

The calculation of safe distance for radiofrequency radiation exposure limits has been sent to the file. 2. (a) The 24dBi parabolic antenna was tested at 24dbm (level 5). The actual output when set to level 5 is not exactly 250mW; in this case it was 220mW. The 17 dbi Yagi was tested at 26dbm (level 7). Both of these power levels are in accordance with FCC rules 15.247(b)(1) and 15.247 (b)(3)(i). Page 59 of the manual has been corrected. 200 mW is incorrect. Please change that. The transmitter should be granted 26dbm maximum output power (as used with the 17 dbi Yagi). (b) This has been changed in the manual. (c This has been changed in the manual. I have also sent a new user’s manual to the file. Should you have any questions with regards to this, or need any further information, please advise. Regards, Sharon A. Hoffman/TIMCO ENGINEERING, INC.

Calculation of Safe Distance for Radiofrequency Radiation Exposure Limits The Limits for Maximum Permissible Exposure to Radiofrequency Radiation are set out in FCC Document 47 CFR Ch. I paragraph 1.1310. The limits for uncontrolled exposure are 1 mW/cm 2 The distance from an antenna resulting in a power density of greater than 1 mW/cm 2 , can be calculated from the equation: S=EIRP / 4π R 2 Or R=√EIRP / 4πS Where:S is the power density in mW/cm 2 R is the distance from the center of the antenna in cm EIRP is the equivalent isotropically radiated power ( P tx x G antenna ) For a 24dBi gain parabolic antenna, and a transmit power of 24dBm, the EIRP is 48dBm, or 6.3E4 mW R= √EIRP / 4πS = √6.3E4 / 4π = 71cm We therefore recommend that an installer stay 1meter (100cm or 3.5ft) from the antenna while it is transmitting. We also recommend that the antenna be installed such that it is at least 1m away from any easily accessible public location.

Shielded interface cables were used in all cases except for cables connecting to the telephone line and the power cords. A test program was run which simulated a normal data transmission on a network. POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 76oF with a humidity of 55%. BANDWIDTH 6.0dB: The measurements were made withe the spectrum analyz- er's resolution bandwidth(RBW)=100KHz and the video bandwidth(VBW) =300KHz and the span set as shown on plot. POWER OUTPUT: The RF power output was measured at the antenna feed point using a peak power meter. ANTENNA CONDUCTED EMISSIONS: The RBW=100KHz, VBW=300KHz and the span set to 100MHz and the spectrum was scanned from 30MHz to the 10th Harmonic of the fundamental. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth(RBW) of the spectrum analyzer was 100kHz up to 1GHz and 1.0MHz above 1GHz with an appropriate sweep speed. The VBW above 1.0GHz was = 10Hz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The ambient temperature of the UUT was 89oF with a humidity of 86%. APPLICANT: TELLUMAT(PTY) LIMITED. FCCID: ONJ6…
