You can connect your RSU to a computer or to a small office/home office (SOHO) local area network (LAN) through a hub, switch, or router. BEFORE YOU BEGIN •Make sure your computer is equipped with an Ethernet network interface card (NIC). •The Ethernet cable that is supplied with your RSU plugs into any standard Ethernet NIC. The NIC is not provided with the RSU, but you can purchase a NIC at most computer and electronics stores. •Find an appropriate location for your RSU. •Make sure you are operating the RSU in a room near an out- side window on the first or second floor of your home or office. •You need to locate the RSU close to a wall outlet. The RSU uses a standard power supply and can sit on a desktop or shelf. •Your RSU comes with a category-5 Ethernet cable. If you choose to place the RSU a good distance from your comput- er, you may need to purchase a longer Ethernet cable. If you purchase a cable, make sure the cable is a category-5 Ethernet cable with RJ-45 connectors on each end. Make sure the longer cable that you might purchase is flexi- ble enough to bend under the bottom of the RSU. •Locate the components shipped with your RSU device: •RSU device •Software CD-ROM •RSU Installation Guide and Quick Start Guide •Power cable and power supply box •Ethernet cable 2 Figure 1 illustrates the RSU package contents.

(a) Requirements of this section are a consequence of Commission responsibilities under the National Environ-mental Policy Act to evaluate the environmental significance of its actions. See subpart I of part 1 of this chapter, in particular § 1.1307(b). (b) For purposes of this section, a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. In this context, the term ‘‘fixed location’’ means that the device is physically secured at one location and is not able to be easily moved to another location. Transmitting devices designed to be used by consumers or workers that can be easily relocated, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation requirement. (d) The limits to be used for evaluation are specified in § 1.1310 of this chapter. All unlicensed personal communications service (PCS) devices and unlicensed NII devices shall be subject to the limits for general population/un-controlled exposure. (1) For purposes of analyzing mobile transmitting devices under the occupational/ controlled criteria specified in § 1.1310 of this chapter, time-averaging provisions of the guidelines may be used in conjunction with typical maximum duty factors to determine maximum likely exposure levels. (2) Time-averaging provisions may not be used in determining typical exposure levels for devices intended for use by consumers in general population uncontrolled environments as defined in § 1.1310 of this chapter. However, ‘‘source-based’’ time-averaging based on an inherent property or duty- cycle of a device is allowed. An example of this is the determination of exposure from a device that uses digital technology such as a time-division multiple-access (TDMA) scheme for transmission of a signal. In general, maximum average power levels must be used to determine compliance. Calculations: The information contained in 1.1307(b)(1) Table 1 indicates that an RF Exposure label be attached to the transmitting antenna for equipment operating in the MDS and ITFS bands that exceed 1640 Watts EIRP. The NextNet Wireless Expedience system operates at a maximum of 2 watts (33dBm) average power while transmitting. The Customer Premise Equipment (CPE) has a maximum transmit duty cycle of 14.29 % and is based on a TDM frame.

Re: RF Exposure Dear Mr. Dayhoff, The information you have requested for the certification of FCC ID: PHX-MMDS- CPE3 is detailed on the following pages. Regards, Tim Blom Question: From: [email protected] Sent: Wednesday, August 07, 2002 3:43 PM To: [email protected] Subject: RF Exposure To: Tim Blom, NextNet Wireless, Inc. From: Steve Dayhoff [email protected] FCC Application Processing Branch Re: FCC ID PHX-MMDS-CPE3 Applicant: NextNet Wireless, Inc. Correspondence Reference Number: 23614 731 Confirmation Number: EA622125 1) Please provide more details of MPE test: a) was device mounted on wall as in normal use, if not what is expected change in MPE for wall-mount configuration; b) was probe scanned and over what area around device 2) Please verify/demonstrate that MPE probe measures pulsed signals correctly 3) Please submit internal photos showing antenna placements and connections relative to case Response: 1a) The Residential Subscriber Unit (RSU) product was tested in a configuration that could resemble a typical installation. No change in the maximum MPE levels would be expected in a typical installation. 1b) The measurement of the RSU for the MPE requirement was performed at the front, sides, top, bottom and back at 20cm from the case of the product. The only detectable RF energy measured was radiation from the front of the RSU product i.e. main beam of the patch array antenna. 2) NextNet Wireless uses the General Microwave Model 3 Radiation Hazard Meter (RAHAM) for verification of the MPE limits. The Model 3 RAHAM probe design employs three orthogonally oriented thin-film thermoelectric arrays. The technical information from the manufacturer specifies that this device has three 10 dB ranges of 2mW/cm 2 , 20mW/cm 2 , and 200mW/cm 2 . The average power overload is 0.5W/cm 2 , the peak power overload is 30W/cm 2 . The thermocouple sensor absorbs RF/microwave energy thereby heating the thermocouple junction as a result, thermocouple sensors give the correct average (rms) power for all types of signal formats from continuous wave (CW) to pulsed to complex digital modulation, regardless of the harmonic content, waveshape or distortion of the signal. To verify the actual measurement performance of the General Microwave Radiation Hazard Meter Model 3, a test utilizing a NextNet Wireless base station and a customer modem vertically polarized antenna was performed. The NextNet Wireless customer modem is hardware limited such that the maximum transmit duty cycle of 14.29% cannot be exceeded. Because of this, a base station which can operate at 100% transmit duty cycle in test mode will be used to transmit a 2 watt signal with the same signal modulation characteristics as used by the customer modem. The base station was calibrated to provide 2 watts at the coax input to the customer antenna. The customer antenna was inserted into an indoor modem case. At 20cm, the measured exposure was 4.3 mW/cm 2 . Applying the customer modem 14.29% maximum transmitter duty cycle to the 4.3 mW/cm 2 yields the following result: 4.3 mW/cm 2 * 0.1429 = .6145 mW/cm 2 The MPE measurement in the RF Exposure section filed with the FCC indicates a measurement reading of 0.68 mW/cm 2 . NextNet Wireless believes that the General Microwave Radiation Hazard Meter Model 3 measures the MPE of the customer modem signal properly. 3) The photo below shows the relationship of the antenna to the case.
