IONIT Global Inc. requests that the following documents regarding this submission for FCC ID: AD3812 be kept confidential: Exhibit Type File Name Block Diagram Q78-AD3812_Block Diagram.pdf Schematics Q78-AD3812_Schematics.pdf Operational Description Q78-AD3812_Operational Description.pdf Part list Q78-AD3812_BOM.xls Those documents contain detailed system and equipment description and related information about the product which ZTE Corporation considers to be confidential proprietary, a custom design and, otherwise, not releasable to the general public. Since this design is a basis from which future technological products will evolve, ZTE Corporation considers this information would be of benefit to its competitors, and that the disclosure of the information in these documents would give competitors an unfair advantage in the market. Thank you for your attention to this matter. Yours Sincerely, Royce Wang ZTE product approval manager

Request for Modular Approval FCC ID: Q78‐AD3812 Item Requirements EUT 1 The final device is designed for mobile or fixed operation (Portable is not permitted – Reference TCB Exclusion List (17 July 2002) II (g)). There is shield present on the PCB, covering the section of reader. 2 The maximum antenna gain to allow compliance with RF exposure requirements is listed on the Grant of Certification for the module. There is no antenna in this modular, it provides a antenna connector. 3 The licensed module must have a FCC ID label on the module itself. That FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: Contains “FCC ID: Q78‐AD3812” Please refer to the FCC ID label format. Labeling instruction has been provided in the OEM installation instruction. 4 The Grant should include the following words in the device description or grant notes: “modular transmitter” or “transmitter module”. Modular approval is requested for this application. 5 The module must comply with RF exposure requirements. See FCC Rules. Spread Spectrum transmitters must comply with RF exposure limits in 15.247. The module has very low levels of RF energy that it is deemed to comply without testing of specific absorption ratio (SAR). 6 The modular transmitter will be labeled with the FCC ID: Q78‐AD3812, and, if the FCC ID is not visible when the module is 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. This exterior FCC ID Label will use wording, “Contains RFID Transmitter Module FCC ID: Q78‐AD3812”.
