Features and Functions LAON Technology(‘LAON’)’s KUM1000-MA0-03(“MA0-03”) has been designed to meet IEEE 802.11a standard specification requirements adopting 5.0GHz band which provides sufficient number of usable channels for smooth full-duplex audio communications with less frequency interferences. “MA0-03” is LAON’s all-in-one SoC (“KUM1000”) based RF module and Media Access Control (‘MAC’) chip and Baseband Processor (‘BBP’) are all combined in the SoC. “MA0-03” provides a designated internal flash memory for various parameters set up and download of the control-related operating software. It is designed to use with the relevant application devices not applying an extra external CPU as it, by its own CPU, supports external interfaces such as UART, SPI, I2C and GPIO. Also, ‘Direct Conversion’ is applied which is a method to direct convert the Baseband signals from BBP to RF signals and it supports switching function and etc to implement ‘Diversity’ capability.

Compliance to each of the requirements is described below: Item Modular requirement Yes No Please provide a detailed explanation if the answer is “No.” 1 Have its own RF shielding Y All radio frequency circuits are shielded by shield cans. Physical components and tuning capacitors are also inside the shield cans. 2 Have buffered modulation/data inputs (if such inputs are provided) Y There is a CPU in the module to control TX POWER according to Part 15 requirements. There is also a BASEBAND IC with buffered modulation data inputs in the module. 3 The modular transmitter must have its own power supply regulation. Y The module has a voltage regulation circuit that supplies power to the module. The voltage regulation in the module uses highly reliable devices. 4 Meet the antenna requirements of section 15.203 Y Two unique antenna connectors are built into the module, only specific antennas are used. 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing. Y This module was tested in a stand-alone configuration. 6 Be labeled with its own FCC ID number, 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. Y There is an FCC ID label permanently attached to the module. 7 The modular transmitter is manufactured so that the user can not influence the operation of the transmitter that will operate outside of the scope of the regulations. Y This module is compliant with all applicable FCC rules. 8 Address compliance with the Commission`s RF exposure limits in Sections 1.1310 and 2.1093. Y This module is compliant with all applicable RF exposure requirements. RF Exposure is addressed in the test report. Note: (1) LMA may be granted when one or more of the requirements in the table above cannot be demonstrated. LMA will also be issued in those instances where applicants can demonstrate that they will retain control over the final installation of the device, such that compliance of the end product is assured. In such cases, an operating condition on the LMA for the module must state that the module is only approved for use when installed in devices produced by a specific manufacturer. When LMA is sought, the application for equipment certification must specifically state how control of the end product into which the module will be installed, and will be maintained, such that full compliance of the end product is always ensured. (2) Please provide Clear and specific instructions describing the conditions, limitations and procedures for third-parties to use and/or integrate the module into a host device. (3) For non-Software Defined Radio transmitter modules where software is used to ensure compliance of the device, technical description of how such control is implemented to ensure prevention of third party modification must be provided (see KDB 594280). Note 1: Compliance of a module in its final configuration is the responsibility of the applicant. A host device will not be considered certified if the instructions regarding antenna configuration provided in the original description, of one or more separately certified modules it contains, were not followed. Example: A separately certified low-power transceiver module using Bluetooth technology which is housed in a desktop computer, laptop or peripheral does not require the overall system to be recertified, if the desktop computer, laptop or peripheral, as a stand-alone unit, complies with all applicable technical standards.
