Part 25 Satellite Communications 6.0 Introduction 6.0.1 Product Description The Eagle Iridium L-Band Repeater unit (ILR) is a uplink and downlink repeater designed to be used in conjunction with the Iridium Subscriber System operating under the frequency constraints outlined in CFR 25.20R(4): this repeater provides signal downlink and uplink in obstructed areas.

WAYNE LANGSTON, INC. Model: J-DR05 FCC ID: LOKJHJLBT05A00021 Date: 10-22-2003 Page 3 of 10 WLI Project: 20031846 These satellite phones consist of an L-Bank Transceiver (LBT) capable of simultaneous transmit and receive (duplex) operation covering the frequency range of 1616 MHz to 1626.5 MHz. The frequency accesses used for duplex channels are organized into sub- bands each of which contains eight frequency accesses. Each sub-band, therefore, occupies 333.33 kHz (i.e. 8 s 41.667 kHz). Up to 30 sub-bands containing 240 frequency accesses may be used for duplex channels. 6.1.1 Requirements The Sebring is subject to FCC Part 25, Subpart C and Part 2 for FCC Certification for units marketed within the United States. The following tests, as specified in FCC Part 2, with limits as defined in FCC Part 25, and shown were performed on the Mobile Iridium Subscriber Unit (ISU). Frequency allocation is defined under 25.202(4)i.

The unit was configured for operation at three (3) different ‘traffic channels’, i.e. low, mid, and high, using the Iridium 9505 handset as the exciter (FCC ID: IHDT6NF1) driving the ILR EUT at the max input required to develop +37 dBm or + 10 dBm respectively. This was accomplished using Pads. These setting were accomplished through direct Key Pad Programming (KPP) with the 9505 in “Test

Ancillary Equipment Item Number Handset 9505 L-Bank Repeater (ILR) Noted Filter Lorch 6CFX-1624/10 S (Exciter) A special test Subscriber identity Module (SIM) was required for KPP operation. The Test Mode is accessed by suspending the phone, i.e. depressing and holding the “#” key for approximately 3 seconds. The Static Traffic Channel command, “29xxyyzabc#”, was used to select the appropriate channel and maximum power output level. The transmitter was modulated with typical DEQPSK modulation using pseudo-random data. General test setups are shown as Figures 6.1-1 and 6.1-2 Figure 6.1-1 General Radiated Test Setup for Tests

Refer to Figure 6.1.2 and 6.1-3 for test setups.

WAYNE LANGSTON, INC. Model: J-DR05 FCC ID: LOKJHJLBT05A00021 Date: 10-22-2003 Page 7 of 10 WLI Project: 20031846 The radiated emissions between 30 MHz and 1 GHz were initially measured in a semi- anechoic shield room in order to identify the emissions in an ambient free environment before proceeding to the open area test site (OATS). This provides the capability of taking accurate measurements in a higher ambient environment such as at the rooftop OATS. The Rhode and Schwarz EMI Receiver System was used for the pre-scans. Typically, signals within approximately 10 dB of the limit are noted for measurements on the OATS. Final measurements on the OATS were taken with a Rhode 7 Schwarz EMI Receiver System at a 3-meter test distance from the receiving antenna. The Sebring was placed on a .8-meter high non-conductive table on a rotating turntable that is flush with the site ground plane. The receiving antenna was scanned over a height range from 1 to 4 meters in both antenna polarities, and the turntable was rotated 360 degrees. The highest emissions were recorded and the final field strength level determined using the following formula: Field Strength (dBµV/m)=Measured Level (dBµV) + Cable Loss (dB) + Antenna Factor (dB) The radiated emissions between above 1 GHz were measured in an anechoic chamber using a EMCO 3115 Horn antenna at a 3-meter distance. The emissions were maximized by rotating the equipment on the turntable and by changing polarities of the antenna. The test methods of ANSI 63.4 were used for performing the Radiated Emissions tests. 6.1.5 Conducted Spurious Emission, 30 MHz to 16.3 GHz Procedure

WAYNE LANGSTON, INC. Model: J-DR05 FCC ID: LOKJHJLBT05A00021 Date: 10-22-2003 Page 8 of 10 WLI Project: 20031846 Conducted spurious emissions are the radio frequency voltages or power generated within the equipment and appearing at the equipment’s output terminal when properly loaded into its characteristic non-radiating artificial load. The mean power of the conducted spurious and harmonic emissions shall be attenuated below the mean output power of the transmitter by: Frequency Offset Attenuation (per 4 kHz) 20.833 to 41.667 kHz 25 dBc 41.337 to 104.16 kHz 35 dBc > 104.16 kHz 51.45 dBc In the range of the frequencies between 1559 to 1605 MHz, emissions shall not exceed an EIRP density level of –70 dBW/MHz (-40 dBm/MHz) averaged over any 20 ms period and –80 dBW (-50 dBm) for any discrete (BW<600 Hz) spurious emissions. EIRP measurements were performed using a maximum worst-case antenna gain of 3 dBi included in the offset of the measurement system along with other measurement system losses. The spectrum was scanned from 30 MHz to the tenth harmonic of the carrier. The level of the carrier and the various conducted spurious and harmonic emissions were measured by means of a calibrated receiver system. All signals were measured with peak detection (worst case) except at frequencies between 50% to 250% of the carrier and the 1559 to 1605 MHz band where average measurements were taken using an external frame trigger

The RF output, DC current and RF Input Power are all time- averaged values which reflect a 9.2% (8.28 ms T x bursts/90 ms frame) transmit duty cycle characteristic of transceiver operation. RF Output: Power Input Power Output Gain Actual Downlink -52 dBm +20 dBm +72 dB+19.7 Uplink -25 dBm +37 dBm +62 dB36.98 Since the transceiver is intended for use with specific antennas (with a worst-case 3 dBi gain over isotropic and “non-standard” RF connector), EIRP is measured. The antenna substitution method was used. The results indicated is the maximum EIRP found over the channels and transceiver orientations tested. The measured value reported below again takes into account the transmit duty cycle of 9.2%. Maximum EIRP: +30.7 dBm (1.2W) 6.2.2 Radiated Spurious Emissions Measurement Test Results All measurements were made with the EUT transmitting at its maximum rated output of 100 and 5 watt powers. Most of the measured signals displayed significant margin, > 20 dB, as compared to the appropriate limits. All of the measured signals were below the

The measured signals are shown in the data of Appendix A. 6.2.3 Conducted Spurious Emissions Measurement Test Results The conducted spurious emissions were measured on the Sebring and were all below the required limits.

The frequency accesses used for duplex channels are organized into sub- bands each of which contains eight frequency accesses. Each sub-band, therefore, occupies 333.33 kHz (i.e. 8 s 41.667 kHz). Up to 30 sub-bands containing 240 frequency accesses may be used for duplex channels. Inter-modulation Conducted Data The amplifier was placed on the Table in the Semi-Anechoic Chamber. The output of which, the uplink 5 Watt output, was placed on the input of an HP 8591 and eventually a TEK 491 25 GHz analyzer using proper attenuators. The input to the uplink was attached and the standard receive antennae phone. The transmit antennae was setup at 3 meters in semi-anechoic chamber with the 9505. The carriers was established at both ends of the allocated spectrum. The frequency specific was evaluated from 30 MHz to 16.3 GHz. A plot of one of these combinations is available in Figure 3. A complete list of the frequencies and actual plots as attached.
