Note: The parameters provided in this report are solely for our companys prototype debugging and do not represent the final production status of your companys project. If your company has a prototype with the latest trial production or updated version (such as material replacement, software update, or environmental processing change), please submit it to us for verification as soon as possible to confirm whether the antenna performance is affected. If your company needs to send the antenna to a third party for retest or to the customer for test, please submit the machine to be tested to our company for test confirmation, because the consistency of the motherboard, the consistency of the assembly, and the difference in the antenna assembly may lead to the deviation of the antenna parameters.
