(a) Specific absorption rate (SAR) shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in § 1.1307(b) of this part within the frequency range of 100 kHz to 6 GHz (inclusive). (b) The SAR limits for occupational/controlled exposure are 0.4 W/kg, as averaged over the whole body, and a peak spatial-average SAR of 8 W/kg, averaged over any 1 gram of tissue (defined as a tissue volume in the shape of a cube). Exceptions are the parts of the human body treated as extremities, such as hands, wrists, feet, ankles, and pinnae, where the peak spatial-average SAR limit for occupational/controlled exposure is 20 W/kg, averaged over any 10 grams of tissue (defined as a tissue volume in the …

□ Normal □ Internal Use ■ Confidential □ Restricted Confidential Project I Antenna Report WNC SAS Tested By Martin Chen 2025/06/29 2 □ Normal □ Internal Use ■ Confidential □ Restricted Confidential Testing Setup(passive Testing) DUT 2. The SG 24 is ideal for the OTA testing of mobile device conformance, particularly for LTE, 5G (<10 GHz) and WiFi protocols. It offers a measurement speed up to 3 times faster and a considerably higher dynamic range in passive antenna measurement mode than the previous version. Available in 3 sizes, with the standard and large models CTIA certifiable. Measurement capabilities driven by MVG WaveStudio software: - Antenna Measurement: Radiation pattern, gain, efficiency with NF to FF transformation and advanced post-processing - OTA Testing including major and 5G protocols: • LTE TDD, FDD, LTE Carrier Aggregation & user defined band, • WiFi a/b/g/n/ac, • NB-IoT, • LTE Cat M1, • and more. 1. 1.Equipment Setup - S parameter •Test Procedure 1.1 Set start and stop frequency and Calibrate the NA with 50 ohm calibration kit 1.2 Connect the NA cable to DUT antenna via SMA or I-PAX connector. 1.3 Measure the DUT antenna performance in the free space and record the s11.

If the RF characteristics of a certified device remain unchanged from the initial certificate, and the PCB layout, hardware components, and software are not changed, no further action is deemed necessary. The product remains compliant with all requirements in the new issue and can continue to be manufactured, imported, distributed, leased, offered for sale, or sold in United States. For any changes or uncertainties regarding the device, all supporting RF characteristics must be verified by Bureau Veritas.
