Section 8 Testing data Test name Clause 27.53 and RSS-139, 4.2, RSS-170, 5.4 Radiated spurious emissions Specification FCC Part 27, RSS-139, Issue 3, RSS-170 Issue 3 8.3 FCC 27.53 and RSS-139, 4.2, RSS-170, 5.4 Radiated spurious emissions 8.3.1 Definitions and limits FCC: (h) AWS emission limits (1) General protection levels. Except as otherwise specified below, for operations in the 1695–1710 MHz, 1710–1755 MHz, 1755–1780 MHz, 1915–1920 MHz, 1995–2000 MHz, 2000–2020 MHz, 2110–2155 MHz, 2155–2180 MHz, and 2180–2200 bands, the power of any emission outside a licensee's frequency block shall be attenuated below the transmitter power (P) in watts by at least 43 + 10 log 10 (P) dB. (3) Measurement procedure. (i) Compliance with this provision is based on the use of measurement instrumentation employing a resolution bandwidth of 1 m egahertz or greater. However, in the 1 megahertz bands immediately outside and adjacent to the licensee's frequency block, a resolution bandwidth of at least one percent of the emission bandwidth of the fundamental emission of the transmitter may be employed. The emission bandwidth is defined as the width of the signal between two points, one below the carrier center frequency and one above the carrier center frequency, outside of which all emissions are attenuated at least 26 dB below the transmitter power. (ii) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to the licensee's frequency block edges, both upper and lower, as the design permits. (iii) The measurements of emission power can be expressed in peak or average values, provided they are expressed in the same parameters as the transmitter power. RSS-139, Section 6.6: i. In the first 1.0 MHz bands immediately outside and adjacent to the equipment’s smallest operating frequency block, which can contain the equipment’s occupied bandwidth, the emission power per any 1% of the emission bandwidth shall be attenuated below the transmitter output power P (in dBW) by at least 43 + 10 log10 p (watts) dB. ii. After the first 1.0 MHz outside the equipment’s smallest operating frequency block, which can contain the equipment’s occupie d bandwidth, the emission power in any 1 MHz bandwidth shall be attenuated below the transmitter output power P (in dBW) by at least 43 + 10 log 10 p (watts) dB. RSS-170, Section 5.4: The transmitter unwanted emissions shall be measured for all channel bandwidths with the carrier frequency set at both the highest and lowest channels in which the equipment is designed to operate. The e.i.r.p. density of unwanted and carrier‑off state emissions outlined in this section (Section 5.4) shall be averaged over any 2‑ms active transmission using an RMS detector with a resolution bandwidth of 1 MHz for broadband emissions and a resolution bandwidth of 1 kHz for discrete emissions, unless stated otherwise. For ATC equipment operating in the bands 2000-2020 MHz and 2180-2200 MHz, the unwanted emission limits shall be determined using a measurement bandwidth of 1 MHz or greater. However, in the 1 MHz band immediately outside and adjacent to the equipment's operating frequency block, a resolution bandwidth of at least 1% of the occupied bandwidth may be employed. 5.4.1.2 ATC Base Station Equipment operating in bands 2000-2020 MHz and 2180-2200 MHz he unwanted emissions of ATC base station equipment transmitting in the bands 2000-2020 MHz and 2180-2200 MHz shall comply with the following: (1) The power of any unwanted emissions at frequencies outside the equipment's operating frequency block shall be attenuated below the transmitter power P (dBW), by 43 + 10 log p (watts), dB. (2) For equipment operating in the band 2180–2200 MHz, in addition to (1), the power of any emissions on all frequencies between 2200 MHz and 2290 MHz shall not exceed an e.i.r.p. of −100.6 dBW/4 kHz (−70.6 dBm/4 kHz).* * This requirement is for implementation and is enforced at the time of licensing. Therefore results are not included in this report. 8.3.2 Test summary Test date July 18, 2018 Test engineer Predrag Golic Report reference ID: 356914-1TRFWL-R1 Page 41 of 49

All measurements were performed using a peak detector. RBW within 30–1000 MHz was 100 kHz and 1 MHz above 1 GHz. VBW was wider than RBW. Testing was performed with RF ports terminated with 50 Ohm load. 8.3.4 Test data Figure 8.3-1: Radiated emissions setup photo – below 1 GHz Report reference ID: 356914-1TRFWL-R1 Page 42 of 49
