RTL8822CE 概要
A WLAN combo module is a complete wireless connectivity subsystem that integrates the MAC, baseband, RF transceiver, and antenna interface on one card, plugging into a host through a standard M.2 edge connector. In the connectivity hierarchy, the RTL8822CE sits between discrete WLAN NICs and system-on-chip solutions: it is a Wi-Fi 5 (802.11ac Wave-2) plus Bluetooth radio targeting notebooks, mini PCs, and embedded boards.
Key features include 2T2R dual-band operation in the 2.4 GHz and 5 GHz bands, 802.11ac Wave-2 MU-MIMO and 802.11n MIMO support, and Bluetooth 5.0 dual mode with backward compatibility to v4.2 and v2.1. Security encryption support covers WEP, WPA, WPA2, WPA3, WPS, and 802.1x. The WLAN subsystem attaches to the host over PCI Express, while the Bluetooth subsystem uses USB, giving designers two independent radio interfaces in one compact card.
Technically, the RTL8822CE combines a WLAN MAC, a 2T2R-capable WLAN baseband, and the RF front end in a single chip. MU-MIMO allows simultaneous serving of multiple clients on the downlink, improving aggregate throughput in dense environments, while dual-band concurrency planning lets designers balance range (2.4 GHz) against throughput (5 GHz).
Typical applications include notebook and mini PC wireless upgrade or repair, embedded systems and IoT gateways needing reliable dual-band Wi-Fi plus BLE, and industrial host boards using the common M.2 A/E key slot. Because it is a mature, widely whitelisted part, it is a frequent drop-in service replacement in HP, ASUS, and other laptop platforms.
One design consideration: many consumer laptop BIOSes enforce a Wi-Fi card whitelist, so verify host compatibility before substituting a different vendor module; also note the RTL8822CE is a Wi-Fi 5 part and does not support Wi-Fi 6 (802.11ax).

主な用途
RTL8822CE の用途: 6 件s: Notebook and Mini PC Wi-Fi Repair/Upgrade, Embedded Systems and Industrial Gateways, IoT Devices and Smart Home Hubs, Set-Top Boxes and Media Streaming Devices, Gaming and Low-Latency Wireless Clients, Security and Surveillance Camera NVRs.
Notebook and Mini PC Wi-Fi Repair/Upgrade
The RTL8822CE is one of the most widely factory-fitted Wi-Fi 5 combo cards in HP, ASUS, and other laptop platforms, making it the default service replacement for failing wireless connectivity. Its 2T2R dual-band 802.11ac design delivers up to 867 Mbps PHY rate in the 5 GHz band, restoring original system performance, while Bluetooth 5.0 dual mode supports mice, headsets, and keyboards over the USB interface. Because it uses the standard M.2 2230 A/E-key edge connector with PCIe WLAN, installation requires no rework - just swap the card and reinstall the Realtek driver. Technicians should note that staying with an RTL8822CE-based card avoids the BIOS whitelist issues reported when substituting Intel AX-series cards in some consumer laptops.

Embedded Systems and Industrial Gateways
Embedded boards and industrial gateways with an M.2 A/E key slot use the RTL8822CE to add certified dual-band wireless connectivity without RF design effort. The 2T2R architecture provides spatial diversity that improves link reliability in metal-rich factory environments, while 802.11ac Wave-2 MU-MIMO sustains throughput when multiple field clients share the uplink. The 2.4 GHz band serves long-range telemetry, and the 5 GHz band handles high-bandwidth data offload up to 867 Mbps. Bluetooth 5.0 over USB enables BLE provisioning and sensor pairing from the same card. Designers should route the PCIe lanes and USB BT signals per the host reference design and mount antennas with at least 2 dBi gain for the 5 GHz band to realize full MU-MIMO performance.
おすすめ
IoT Devices and Smart Home Hubs
Smart home hubs benefit from the RTL8822CE combination of dual-band Wi-Fi and Bluetooth 5.0 on a single M.2 card: Wi-Fi handles cloud connectivity and LAN media streaming at up to 867 Mbps, while BLE handles device onboarding, beacons, and low-power sensor networks. Dual-mode Bluetooth with v4.2/v2.1 backward compatibility covers the broad installed base of legacy BLE peripherals. Security support including WPA2, WPA3, and 802.1x addresses the authentication requirements of modern IoT deployments. The card's low power profile suits always-on hub hardware, and the standard M.2 form factor lets one carrier board design serve multiple product SKUs by populating or omitting the wireless card.
おすすめ
Set-Top Boxes and Media Streaming Devices
Media streaming set-top boxes require sustained high-throughput wireless to deliver 4K video, and the RTL8822CE's 802.11ac Wave-2 MU-MIMO at up to 867 Mbps on the 5 GHz band provides the needed bandwidth with lower latency than 802.11n designs. MU-MIMO allows the access point to serve the box simultaneously with other clients, reducing buffering during household network congestion. The 2.4 GHz band remains available for remote-control accessories and legacy device pairing, and Bluetooth 5.0 supports audio remote and gamepad connections over USB. Its PCIe host interface integrates cleanly with SoC-based STB platforms that expose standard M.2 or PCIe WLAN slots.
おすすめ
Gaming and Low-Latency Wireless Clients
For entry-level gaming desktops and thin clients without Ethernet, the RTL8822CE provides low-latency dual-band wireless with 2T2R spatial streams that maintain stable throughput under load. Community discussions frequently reference the RTL8822CE as the stock card in gaming laptops such as the ASUS TUF series, where it balances cost and adequate 867 Mbps performance for online play. The 5 GHz band avoids the crowded 2.4 GHz spectrum typical of homes, reducing jitter, while MU-MIMO support keeps round-trip times consistent when multiple devices are active. Users demanding lower latency and Wi-Fi 6 OFDMA may upgrade to Intel AX200NGW/AX210NGW, accepting BIOS whitelist risk on some platforms.
おすすめ
Security and Surveillance Camera NVRs
Network video recorders and surveillance gateways use the RTL8822CE to connect wirelessly to camera clusters where cabling is impractical. The 5 GHz 802.11ac link at up to 867 Mbps sustains multiple 1080p or several 2MP camera streams, while 2T2R diversity improves reception across walls and outdoor structures. Bluetooth 5.0 simplifies local commissioning of cameras and accessories via BLE. WPA2/WPA3 and 802.1x support in the RTL8822CE secures video traffic against unauthorized access, an important requirement in surveillance deployments. Embedding the card in an NVR's M.2 slot also keeps RF components away from noisy storage electronics, and 802.11ac Wave-2 MU-MIMO helps when many cameras transmit simultaneously to the recorder.

設計ノート
BIOS whitelists are the single biggest pitfall when replacing an RTL8822CE in consumer laptops. HP support community threads document AX210NGW installations where Bluetooth worked but the WLAN card never appeared in lspci or Device Manager because the BIOS rejected the non-whitelisted vendor. Before specifying a cross-brand swap, check the service manual for a whitelist or apply a BIOS update; otherwise stay with an RTL8822CE-based module from SparkLAN, Unex, or Waveshare to guarantee recognition.
For embedded carrier boards, route the PCIe differential pairs (WLAN) and USB DP/DM (Bluetooth) as controlled-impedance lines per the M.2 specification, keep them away from switching-regulator nodes, and place the two U.FL/IPEX antenna connectors at the board edge with 2.4 GHz and 5 GHz antennas separated as far as practical. Follow the module vendor's (SparkLAN/Unex) host reference schematic for the W_DISABLE and WAKE sideband signals to retain airplane-mode and wake functionality in the OS.
The RTL8822CE draws its 3.3 V supply from the M.2 slot per the M.2 standard. Ensure the host slot can supply the peak TX current of the 2T2R radio at maximum transmit power - [DATA_NEEDED: exact peak current from datasheet] - and place bulk decoupling near the M.2 connector. Undervoltage during simultaneous Wi-Fi TX and BT traffic causes dropped links; verify supply ripple is within the module datasheet limit before certifying the design.
