Samsung Wi-Fi/BT Transceiver WCH734R Wins FCC Approval

Samsung Electronics has received FCC certification for its Wi-Fi and Bluetooth transceiver model WCH734R under FCC ID A3LWCH734R. The grant occurred on July 8, 2026, for original equipment as an Unlicensed National Information Infrastructure transmitter.

Samsung certifies modular Wi-Fi and Bluetooth module for OEM integration. The device functions as a Wi-Fi/BT Transceiver designed for single modular approval under mobile RF exposure conditions with a 20 cm separation distance. Samsung Electronics Co Ltd serves as the grantee, with the application processed by test firm CTK Co., Ltd. The module supports 20, 40 and 80 MHz modes across multiple 5 GHz bands and carries notes that it is for OEM integration only with no user removable components. Output power is listed as conducted, with MIMO evaluation completed and multi-transmitter requirements noted.

Module operates on 5 GHz U-NII bands with specific power limits. Certified frequency ranges include 5180-5240 MHz at 0.044 W conducted output, 5260-5320 MHz at 0.072 W, 5500-5720 MHz at 0.082 W, and 5745-5825 MHz at 0.076 W. The certification includes Dynamic Frequency Selection testing for radar avoidance on applicable bands. All test reports for WLAN 5 GHz portions and DFS, along with RF exposure evaluation, were submitted on the grant date.

Documentation package includes photos, manuals, and regulatory attestations. Available exhibits total more than a dozen files submitted July 8, 2026, among them a 172 KB user manual, 404 KB internal photos, 261 KB external photos, 174 KB label information, 1.5 MB test setup photos, and 1 MB antenna specifications. Multiple test reports range from 2.8 MB to 5.5 MB each. Attestation statements cover 2.911(d)(7), 2.911(d)(5)(i and ii), DFS uniform spreading, modular approval, software configuration control, confidentiality, power of attorney, and UNII declarations. An RF exposure report of 342 KB completes the package.

Certification paves way for integration into future Samsung devices. Similar modules from Samsung appear in televisions and other connected products, suggesting the WCH734R will likely appear in upcoming smart home, display or consumer electronics devices requiring updated Wi-Fi 6 or Bluetooth connectivity. The grant notes emphasize that the device must comply with all applicable FCC rules for end-product integration, including any required labeling and host device testing where appropriate. No specific end product model is identified in the filing.
