CoreTigo Ltd Agent Authorization Letter Company: CoreTigo Ltd Address: Giborey Israel 5, Poleg, Natanya, Israel 4250405 Product Name: TigoAirLP Model Number(s): CT210-0322-10 Product Description: TigoAirLP We authorize MiCOM Labs Inc., 575 Boulder Court, Pleasanton, California 94566, USA, to act on our behalf on all matters concerning the certification of above named equipment. We declare that MiCOM Labs Inc. is allowed to forward all information related to the approval and certification of equipment to the regulatory agencies as required and to discuss any issues concerning the approval application. Any and all acts carried out by MiCOM Labs on our behalf shall have the same effect as acts of our own. Signature: Date: 2020-11-27 Name: Ofer Blonskey Title: VP R&D Company: CoreTigo Ltd

CoreTigo Ltd Giborey Israel 5, Poleg, Natanya, Israel 4250405 To the certification reviewer: We are hereby applying for limited] modular approval of the above-referenced FCC ID, based on compliance with most of the criteria as detailed below. Sincerely, [signature] [Ofer Blonskey] [VP RnD] Part 15 Unlicensed Single Limited Modular Transmitter Approval Justification per 15.212 Requirement per 15.212 Yes / No reference (i) The radio elements of the modular transmitter must have their own RF shielding. Yes Shielding is provided by a metal cover over the circuitry. (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided. Yes All modulation and data inputs are buffered by circuitry on the transmitter chip. (iii) The modular transmitter must have its own power supply regulation. Yes Power supply regulation is provided by circuitry on the transmitter chip. (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). No The application is intended for professional installation only. (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 parameters. Yes Testing was performed with the module mounted on an evaluation board, as shown in the test setup photos. (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. If the FCC ID is not visible when the module is Yes A sample of the host label is provided as an exhibit, showing the FCC identifier of the module. RE FCC ID: 2ATSM-TAIR2 installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. (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. Yes The module complies fully with the operating requirements of Part 15 section as demonstrated in the test report exhibit. (viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Yes The modular transmitter complies with this requirement, please refer to RF exposure report

FCC ID: 2ATSM-TAIR2 RF Exposure Evaluation Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , Pout = output power to antenna in mW; G = gain of antenna in linear scale, Pi = 3.1416; R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. Test Result of RF Exposure Evaluation Channel Output power to antenna (mW) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result Lowest 5.96 0.00194 1.0 PASS Middle 6.40 0.00209 1.0 PASS Highest 7.11 0.00232 1.0 PASS Remark: antenna gain=2.15dBi
