The VMKAERPROUWB UWB module is used characterize the environment in the vicinity of the sensor by collecting and analyzing propagation information between the antennas, which is affected by the environment. The information is gathered by sequentially transmitting from the available antennas and collecting the received information at the rest of the antennas. The response information is then processed at the hosting device to obtain spatial information about the environment. The acquisition is controlled by the hosting device. The hosting device may ask VMAKERPROUWB to acquire multiple snapshots, so as to integrate the data into information about larger spatial extent, or to detect changes in the environment. 2 Features Three-dimensional radio-frequency based sensor, based on VYYR7201-B4 System-on-Chip for signal generation and recording. A MIMO array of slot embedded antennas is used to obtain high-resolution image. The device is operated by a stand-alone host (PC, Smartphone, or other proprietary host), through a USB-

2 interface or optional WiFi/BLE interface. The power is supplied either by the USB interface, a battery or by an external power supply. 2.1 VMAKERPROUWB model See the table below for details on the model.

Subject: Request for Class II Permissive Change for single module FCC ID : 2AHIS- VMAKERPROUWB and IC : 21498-VMAKERPROU Dear Examiner, This letter is to request a Class II Permissive Change for FCC ID : 2AHIS- VMAKERPROUWB and IC : 21498-VMAKERPROU The newly model VMPRO19EB4 differs from the VMPRO19CB4 model (which was certified under FCC-ID : 2AHIS- VMAKERPROUWB and IC : 21498-VMAKERPROU) only by a minor layout modification in the supply network and modified data interface via ESP32 IC . No changes to the UWB RF portion were done. The models are equivalent in terms of their RF characteristics, as tuned by calibration procedure and validated by the testing, therefore the differences are minor enough to count as permissive-change and described in the technical description attached. Sincerely, Naftali Chayat Page 1

August 11, 2022 Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Attestation Statement FCC ID: 2AHIS-VMAKERPROUWB In the matter of Vayyars submitted documentation for compliance of the electronic module assigned FCC ID 2AHIS- VMAKERPROUWB, Vayyar hereby states that 1) The modified product meets the requirements of C2PC under the C2PCPX procedure 2) The modified product continues to meet the modular approval requirements. 3) That the modified product is intended solely for use in Vayyar product and shall not be marketed as a module to other parties The KDB 178919 Notification 202109-011 document outlines 9 requirements, which are addressed hereby:

1) The requirements of 2.1043 are fulfilled, i.e., the devices block functions for the fundamental frequency, primary modulator circuit, maximum power, or field strength ratings shall remain unchanged. A: COMPLY. 2) Transmitter PCB layout and parts changes are only permitted if there is no change in identifying a devices form, functional specification, as initially granted or previously approved under a Class II permissive change. A: COMPLY. The form remains same. 3) PCB changes are limited to non-substantive modifications layout changes to the same size physical circuit board previously granted. A: COMPLY 4) C2PCPX is not permitted to add, remove, augment, or change capabilities, such as transmitters, increased bandwidth, additional rule parts, bands, etc. ANSWER: The Module 2AHIS-VMAKERPROUWB is tested for UWB, the control is done through Host Device 2AHIS-VMAKERPROWs WiFi. The Host Product is obliged to pass certification according to the WiFi test procedures. The UWB module (2AHIS-VMAKERPROUWB) will be sold only as part of the Host Device (2AHIS-VMAKERPROW). Vayyar will be the only host integrator of the module (i.e. will never be sold to 3rd parties as a standalone module). 5) In the PAG submission for item C2PCPX, the applicant shall provide complete information on testing demonstrating that the proposed changes for fundamental emissions are unchanged within the normal, acceptable tolerances and out-of-band; emissions do not exceed the appropriate limits. The PAG submission shall include all applicable test reports and internal photos. A: See attached data. 6) The modified device shall not be marketed under the existing grant of certification before confirmation that the C2PCPX PAG is approved and granted. A: We respectfully await C2PCPX PAG approval 7) Software Defined Radio (SDR) grants that use the C2PCPX procedure are not permitted to make subsequent Class III permissive changes. A: It is not a SDR product 8) The C2PCPX PAG procedure has no impact on the provisions of V) of this publication for non-SDR software-only changes; thus, adding an equipment class when related to rule changes is still permitted. A: It is not a SDR product 9) Class I permissive changes are not permitted under this C2PCPX procedure. A: We are applying for C2PC approval Yours sincerely, Name: Naftali Chayat Title: CTO Company: Vayyar Imaging Ltd

22 October 2020 Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Modular Approval Request FCC ID: 2AHIS-VMAKERPROUWB The following attestation addresses the requirements to support modular approval:

Modular approval requirement Yes (provide brief statement) No *

(a) The radio elements must have the radio frequency circuitry shielded. Physical components and tuning capacitor(s) may be located external to the shield, but must be on the module assembly

(b) The module must have buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal

(c) The module must contain power supply regulation on the module

(d) The module must contain a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per Sections 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b)

(e) The module must demonstrate compliance in a stand-alone configuration

(f) The module must be labelled with its permanently affixed FCC ID label, or use an electronic display (See KDB Publication 784748 about labelling requirements) Yes. The radio elements of VMAKERPROUWB shielded. Yes, the data signals are buffered by either the USB or SPI interconnection, and further by the data bus of VYYR7201 component. The modulation of radio signals is performed internally to the VYYR7201 and is not driven directly by the data inputs Yes, VMAKERPROUWB has on-board voltage regulators (see schematics) Yes, VMAKERPROUWB has antennas embedded on the PCB board. Yes, VMAKERPROUWB receives its power supply through a USB cable from the hosting device or a battery pack, and operates autonomously per host-trigger. VMAKERPROUWB has a e-

LABEL of FCC ID, which is displayed on the host.

(g) The module must comply with all specific rules applicable to the transmitter. The grantee must provide comprehensive instructions to explain compliance requirements The product complies with the FCC RF Exposure requirements, as demonstrated within the supplied RF Exposure exhibit Modular approval requirement Yes (provide brief statement) No *

(h) The module must comply with RF exposure requirements See the Part 15F and other related data in the rest report. The average transmit power of VMAKERPROUWB devices is far below the RF exposure threshold.

* Please provide a detailed explanation if the answer is No. Yours sincerely, Name:
