LANDROAD Inc. Covered Equipment Certification Attestation Letter May 23, 2024 Nemko North America, Inc. 303 River Road Ottawa K1V 1H2 Canada ATTN.: Reviewing Engineer FCC ID: 2BGJWROADRAINLTEN LANDROAD Inc. (“the applicant”) certifies that the equipment for which authorization is sought is not “covered” equipment prohibited from receiving an equipment authorization pursuant to section 2.903 of the FCC rules. Note: If the equipment for which the applicant seeks authorization is produced by any of the entities identified on the current Covered List, the applicant should include an explanation on why the equipment is not “covered” equipment. LANDROAD Inc. (“the applicant”) certifies that, as of the date of the filing of the application, the applicant is not identified on the Covered List as an entity producing “covered” equipment.

Certification designating a U.S. Agent for service of process: As required by section 2.911(d)(7), the applicant must designate a contact located in the United States for purposes of acting as the applicant’s agent for service of process, regardless of whether the applicant is a domestic or foreign entity. An applicant located in the United States may designate itself as the agent for service of process. In either scenario, the designation of the U.S. agent for service of process should be provided as an attachment to the equipment authorization application. The applicant must provide a written certification, which must: i. Be signed by both the applicant and designated agent for service of process, if the agent is different from the applicant. ii. Acknowledge the applicant’s consent and the designated agent’s obligation to accept service of process. iii. Provide a physical U.S. address and email for the designated agent. iv. Acknowledge the applicant’s acceptance to maintain an agent for no less than one year after the grantee has terminated all marketing and importation or the conclusion of any Commission-related proceeding involving the equipment. Unofficial information provided by FCC personnel on February 14, 2023, via the monthly call with the TCB Council: The Agent for Process of Service: • cannot be a TCB or affiliated with a TCB (e.g. could not be a person who works for a TCB or a company that owns or is owned by the TCB) • cannot be a [FCC recognised] Lab or affiliated with a test lab (e.g. could not be a person who works for a Lab or a company that owns or is owned by the Lab) • Agent can be Individual Entity or a Company Entity • Agent Entity must be located in US, US address/phone • Entity acting as Agent must have FRN (best practice, put FRN on Agent Letter) • Agent letter does not have to be FCC ID specific, can be general Agent for Grantee For devices being marketed or for which marketing has ceased for less than 1 year, if the Agent for Process of Service changes, then for every TC Number the TCB must request the FCC to put application into Audit Mode and Agent Letter needs to be updated (superseded). NOTE: The U.S. Agent for Service of Process should not be confused with the authorized agent used for signing the 731 form, other cover letters within the application, and/or the agent who may interface with the TCB.

OCCUPIED BANDWIDTH 11.1 Operating environment Temperature : 22 °C Relative humidity : 45 % R.H. 11.2 Test set-up The emission bandwidth (×dB) is defined as the frequency range between two points, one above and one below the carrier frequency, at which the spectral density of the emission is attenuated × dB below the maximum in-band spectral density of the modulated signal. Spectral density (power per unit bandwidth) is to be measured with a detector of resolution bandwidth in the range of 1% to 5% of the anticipated emission bandwidth, and a video bandwidth at least 3× the resolution bandwidth. When the occupied bandwidth limit is not stated in the applicable RSS or reference measurement method, the transmitted signal bandwidth shall be reported as the 99% emission bandwidth, as calculated or measured. • The transmitter shall be operated at its maximum carrier power measured under normal test conditions. • The span of the analyzer shall be set to capture all products of the modulation process, including the emission skirts. • The resolution bandwidth (RBW) shall be in the range of 1% to 5% of the occupied bandwidth (OBW) and video bandwidth (VBW) shall be approximately 3×RBW. 11.3 Test Date January 15, 2024 ~ February 08, 2024 .

Conducted Spurious and Harmonic Emissions at Antenna Termianl 13.1 Operating environment Temperature : 22 °C Relative humidity : 45 % R.H. 13.2 Test set-up (Configuration of conducted Emission measurement) Conducted Spurious Emissions is tested in accordance with KDB971168 D01 Power Meas License Digital Systems v03, April 9, 2018, Section 6. The EUT makes a call to the communication simulator. The power was measured with R&S Spectrum Analyzer. All measurements were done at 3 channels(low, middle and high operational range.) The Conducted Spurious Emissions used the power splitter via EUT RF power connector between simulation base station and spectrum analyzer. The communication simulator station system controlled a EUT to export maximum output power under transmission mode and specific channel frequency. Conducded spurious emissions The EUT was setup to maximum output power. The 100 kHz RBW and 300 kHz VBW was used to scan from 30 MHz to 1 GHz. Also, the 1 MHz RBW and 3 MHz VBW was used to scan from 1 GHz to 20 GHz. The high, low and a middle channel were tested for out of band measurements. 13.3 Limits Rule Part 24.238(a) specifies that “on any frequency outside a licensee's frequency block, the power of any emission shall be attenuated below the transmitter power (P) by at least 43 + 10 log10 (P) dB.” = P(W) – [43 + 10log(P)](dB) = [30+10Log(P)] (dBm) - [43 + 10log(P)](dB) = -13 dBm Limit -13 dBm 13.4 Test Date January 15, 2024 ~ February 08, 2024 Radio Communication Analyzer Spectrum Analyzer EUT Directional Coupler Page 88 of 154 Report No. : OT-245-RWD-026 It should not be reproduced except in full, without the written approval of ONETECH Corp.
