| Modular approval. Output power listed is conducted. This device supports 2x2 MIMO operation and 20 MHz bandwidth. The module antennas must be installed to meet the RF exposure compliance separation distance of 20 cm and any additional testing and authorization process as required. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures. The module grantee is responsible for providing the documentation to the system integrator on restrictions of use, for continuing compliance of the module. The host integrator must follow the integration instructions provided by the module manufacturer and ensure that the composite-system end product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules and to KDB Publication 996369. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369. |
| CC: | This device is certified pursuant to two different Part 15 rules sections. |
| MO: | This Multiple Input Multiple Output (MIMO) device was evaluated for multiple transmitted signals as indicated in the filing. |
