The only change to the configuration of the EUT while testing was the adjustment of the test firmware to power setting “F0”, this is the most correct setting for the radio card (FCC ID: NI3- 2511CD-PLUS3) found in this unit. In the final production unit the power level is not user configurable. The measurements presented in NCEE report “R052203-01A” were made using that power setting; both conducted and radiated measurements from the RF port are presented. The conducted emissions results were unaffected. Doug Kramer Lab Manager NCEE

All radiated measurements above 1GHz were made 1MHz RBW and measurements below 1GHz were made with 120kHz RBW as stated in Section 4.0 of the report unless otherwise noted. 12) Several of the limits do not appear to be correctly applied. For instance, measurements made in the 4.5 GHz to 5.15 GHz range should have a limit of 54 dBuV/m for AVG and 74 dBuV/m for Peak since they fall in a restricted band of operation. This range on page 13 & 14 does not appear to be correctly shown and it appears to exceed the limits for several measurements. The results have been remeasured, recalculated and represented in the report. A high pass filter was used during measurements above 2GHz and a low pass filter used in measurements below 1GHz. A 10dB attenuator was used when measuring the fundamental. The report has been modified to correctly reflect this and all values have been verified. 13) Please provide detailed information (including plots) to show compliance in the restricted bands at the band edges (2310-2390 and 2483.5-2500 MHz) to the 54 and 75 dBuV/m limits. Plots have been added to the report that show the equipment does not pass into those bands when operating at its extreme frequencies. Page 3 of 3 14) Even thought this device uses a previously approved TX, all applications must be complete and stand on their own. Please note that compliance of the power, 6 dB bandwidth, power spectral density, etc. has not been provide. Please provide this additional test data. Please see that additional attachment which explains appropriate test methods. Thank you for this information. The changes made to the report should provide adequate detail. Sincerely, Doug Kramer Lab Manager NCEE

FCC ID: B5D-CPE200MW Operational Description The DSSS transmitter and receiver of the EUT (Long range, high power wireless CPE) is powered via a PCMCIA interface to the LAN interface PCB. The transmitter and receiver of the EUT are connected to an 18 dBi patch antenna array within the CPE radome enclosure. The LAN interface PCB is connected to an outdoor-rated Ethernet cable (CAT-5) from which it receives both data and DC power. The DC power is injected onto wires 4,5,7 and 8 from a Power-over-Ethernet (PoE) box, which is located near the client’s computer equipment. The client’s computer equipment is also connected to the PoE box with a short length of CAT-5 Ethernet cable. The DSSS transmitter and receiver consists of a PCMCIA radio card, Senao model NL- 2511CD PLUS EXT2 (FCC ID: NI3-2511CD-PLUS3).

FCC ID: B5D-CPE200MW RF Exposure Statement for Telex Model 2473AA: Notice in Installation Manual: FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 40cm (15.75 inches) between the radiator and your body. RF Exposure Calculations: The following information provides the minimum separation distance for the 18 dBi antenna provided as an integral part of Telex Model 2473AA CPE product, as calculated from FCC OET 65 Appendix B, Table 1B Guidelines for General Population/Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1.0 mW/cm^2 uncontrolled exposure limit. The formula used was: S = (Po * G) / (4 * Pi * r^2) or r = SQRT [ (Po * G) / (4 * Pi * S) ] Where S = 1.0 mW/cm^2 for 2400 MHz Where Po = 200 mW (Peak RF) Where G = 63.1 (numeric equivalent to 18 dBi antenna gain) Where r = Minimum Safe Distance from antenna (cm) For Telex Model 2473AA, r = 32 cm (12.77 inches) Notes: 1. The minimum safe distance is based on a conservative “worse case” prediction, i.e. using the formula shown above and no duty factor. In practice the minimum distance could be much shorter. (Ref. 2) 2. The minimum safe distance has been calculated for the maximum allowed Power Density (S) limit of 1.0 mW/cm^2 in the frequency range 1500-100,000 MHz for uncontrolled environments (Ref. 2). 3. The users manual and all documentation for this product recommend a minimum distance of 40cm even though the calculated value is 32cm. References: 1. FCC Part 15, sub-clause 15.247 (b) (4) (i) 2.
