Confidentiality Request Letter Date: 2020/9/7 Federal Communications Commission Authorization and Evaluation Division FCC ID：SQG-LWB5PLUS Permanent Confidentiality Request Pursuant to Sections 0.457 and 0.459 of the Commission’s Rules, the Applicant Hereby requests confidential treatment of information accompanying this Application As outlined below: 1. Block Diagram 2. Circuit Diagram 3. Operational Description The above materials contain trade secrets and proprietary information not customarily released to the public. The public disclosure of these matters might be harmful to the Applicant and provide unjustified benefits to its competitors. The Applicant understands that pursuant to Rule 0.457, disclosure of this Application and all accompanying documentation will not be made before the date of the Grant for this application Sincerely, Bill Steinike, VP of Strategic Business Development Laird Connectivity, Inc. Email: [email protected] Tel: 262-421 -4970

Date: September 7, 2020 Subject: Ad Hoc Mode Function Declaration FCC ID: SQG-LWB5PLUS IC: 3147A-LWB5PLUS To Whom it may concern, We, Laird Technologies declare that the device does not support any non-US channels, country code selection in all the operational mode(s), like Ad-Hoc...etc. for the following product. Also, the client software and associated drivers will not initiate any transmission on DFS frequencies without initiation by a master and the device without support DFS detection capability. This includes restriction on transmissions for beacons and support for ad-hoc peer-to-peer modes. Regards, Bill Steinike, VP of Strategic Business Development Laird Connectivity, Inc.

RF_734_02 04 April 16 Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: SQG-LWB5PLUS Items to be covered by Single modular transmitters. Answer from applicant 1. The modular transmitter must have its own RF shielding. The modular has a shielding Case. Please refer to EUT Photo. 2. 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. The component number is CYW4373E 3. The modular transmitter must have its own power supply regulation. The component number is CYW4373E 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(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). Antenna Connectors are IPEX. And no external amplifier will be used with this modular. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. This modular is tested under stand-alone configuration. Please refer to Test setup photo. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). The modular transmitter is labeled with its own FCC ID number. Please refer to label sample and label location. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the 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 applicatio n for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. The modular complies with this requirement. Please refer to user manual. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. The device complies with this requirement. Please refer to RF exposure report. RF_734_02 04 April 16 Items to be covered by Split modular transmitters. Answer from applicant 1. The modular transmitter must comply with all requirements of a single modular transmitter except for items (1) & (5) of the above single modular approval requirements. 2. Only the radio front end must be shielded. The physical crystal and tuning capacitors may be located external to the shielded radio elements. The interface between the split sections of the modular system must be digital with a minimum signalling amplitude of 150 mV peak-to-peak. 3. Control information and other data may be exchanged between the transmitter control elements and radio front end. 4. The sections of a split modular transmitter must be tested installed in a host device(s) similar to that which is representative of the platform(s) intended for use. 5. Manufacturers must ensure that only transmitter control elements and radio front end components that have been approved together are capable of operating together. The transmitter module must not operate unless it has verified that the installed transmitter control elements and radio front end have been authorized together. Manufacturers may use means including, but not limited to, coding in hardware and electronic signatures in software to meet these requirements, and must describe the methods in their application for equipment authorization. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
