Date: 14 March 2024 DEKRA Testing and Certification, S.A.U. Parque Tecnolgico de Andaluca C/ Severo Ochoa 2 & 6 29590 Campanillas Mlaga, Espaa Ref: FCC Modular approval letter for FCC ID: 2ANPO00NRF9151 To whom it may concern:

The following attestation addresses the requirements to support modular approval pursuant to 15.212 of the Commissions Rules:

Modular approval requirement

(i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements.

(ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation.

(iii) The modular transmitter must have its own power supply regulation.

(iv) The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section.

(v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see 15.31(i)).

(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number.

(vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization.

(viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration.

* Shall provide a detailed explanation if the answer is No. Sincerely, Yes No*

Date: 21 March 2024 NB-IoT offset description Manufacturer: Nordic Semiconductor ASA FCC ID: 2ANPO00NRF9151 IC: 24529-NRF9151 We, Nordic Semiconductor ASA, hereby states that our module nRF9151 has been tested to certify Cat M1 and NB-IoT bands for FCC and ISED certification. The strategy followed to perform this testing was finding the channels outermost of the bands, which complies with the block edge testing; accordingly, we can demonstrate the lowest and highest channels for NB-IoT bands are the following ones:

Lowest Middle Highest Channel Number (Frequency MHz) NB-IoT B2 18602

(1850.2) 18900

(1880) 19198

(1909.8) B4 19952

(1710.2) 20300

(1745) 132670

(1754.8) B5 20402

(824.20) 20525

(836.50) 20648

(848.80) B8 21628

(897.80) 21640

(899) 21652

(900.20) B12 23012

(699.20) 23090

(707) 23179

(715.9) B13 23182

(777.20) 23230

(782) 23278

(786.80) B17 23732

(704.20) 23790

(710) 23848

(715.80) B25 26042

(1850.2) 26365

(1882.5) 26688

(1914.8) B26 20402

(814.20) 20525

(836.50) 20648

(848.80) B66 131974

(1710.2) 132322

(1745) 132670

(1779.8) B85 134004

(698.2) 134092

(707) 134181

(715.9) For NB-IoT technology, an offset of 100 kHz for the first/last transmission channel is needed because the bandwidth required for a transmission is 200 kHz. However, for some bands it has been adjusted the lower and/or higher operating band limits in order to be in compliance with the results obtained in the band-edge test. All measurements have been performed in accordance with the allocated channels above, being the result of the band edge limit test case. The operating frequency bands for this module are defined as above for NB-IoT, and this restriction will be applied by enabling only the above specified bandwidths via firmware setting, without hardware modifications. For ISED the band 26 is limited to B5. Yours sincerely, By: Niko Balabanis Title: Certification Manager Company: Nordic Semiconductor ASA Telephone: +47 72898900 e-mail: niko.balabanis@nordicsemi.no
