These features are applicable to the WCN6856 and WCN6750 connectivity chipsets which are integrated with various SoCs. ### Wi-Fi capabilities The following table provides a feature matrix of the Wi-Fi capabilities that the connectivity chipsets support: Note: Software support for the WCN6856 chipset will be provided in a future release. Table : Wi-Fi software feature matrix | Feature | Feature description | WCN6856 | WCN6750 | | --- | --- | --- | --- | | Supported SoC | QCS5430, QCS6490 | Yes | Yes | | Wi-Fi band | 2.4 GHz, 5 GHz, and 6 GHz | Yes | Yes | | Operational mode | | Yes | Yes | | Maximum bandwidth | | Yes | Yes | | DBS | Supports DBS 4-stream (2 x 2) 2.4 GHz 40 MHz + (2 x 2)

For more information on the list of WFA mandatory
certifications, see [https://www.wi-fi.org/certification](https://www.wi-fi.org/certification) and [https://www.wi-fi.org/certification/programs](https://www.wi-fi.org/certification/programs). | Yes | Yes | ### Operating bands The WCN6856 and WCN6750 Wi-Fi chipsets support operating bands of 2.4 GHz, 5 GHz, and 6 GHz. ### Operating modes The Wi-Fi software operates in the following modes: Table : Operating modes | Mode | Description | | --- | --- | | STA mode | The STA mode allows the device to connect to an AP within a
Wi-Fi network and communicate with other devices in the same
network. This is the standard operating mode for a wireless
device in a Wi-Fi connection. | | Hotspot mode | The hotspot mode allows a device to provide backhaul
(Internet) connectivity to the Wi-Fi clients by using a cellular
link (LTE). The device establishes the connection through its
lightweight hotspot interface, enabling it to: | | Wi-Fi Direct Peer-to-Peer (P2P) mode | The Wi-Fi Direct P2P mode enables two devices to communicate
directly with each other without the need for a third-party AP.
You can use the Wi-Fi Direct mode to transfer files or stream
media between two devices. This mode is useful when you do not
have access to a regular Wi-Fi network or when you need a more
direct, faster connection. | ### Scan A Wi-Fi scan is used to compile a list of nearby APs for a device. The device can scan for APs either actively or passively. Additionally, there are other scan policies that are triggered by WLAN chipsets. Table : Scans that are triggered by WLAN chipsets | Scan | Description | | --- | --- | | Active scan | The Wi-Fi initiates a Tx broadcast probe request and listens
for probe responses from APs. All APs except those with a hidden
Service Set Identifier (SSID) respond to the broadcast probe
request. The Active scans are used on all channels for 2G,
non-Dynamic Frequency Selection (DFS) channels for 5G, and
Preferred Scanning Channel (PSC) for 6G. | | Passive scan | The Wi-Fi conserves power as the client does not actively
transmit any packets, thus reducing channel pollution. The STA
waits on each channel for 100 ms (plus an additional ±10 ms for
channel change) to listen to the beacons broadcasted by APs.
During the dwell time the STA receives all the beacons and scan
SSIDs from the beacons received from APs on that
channel. | | Legacy scan | In a legacy scan, the Wi-Fi scans one channel at a
time. | | Split scan | In a split scan, the Wi-Fi alternates scanning between the
home channel and foreign channel. | | Burst scan | In a burst scan, the Wi-Fi scans multiple channels in a
burst. | | Agile scan | In an agile scan, the Wi-Fi simultaneously scans two passive
channels reducing DFS channel scan time by half. | | Roaming scan | A roaming scan is initiated to move the STA from a congested
channel of the currently connected AP to a better AP. The
trigger for the roam scan can be due to several factors
including Received Signal Strength Indicator (RSSI) of the AP,
missed beacons, channel traffic conditions, and AP
conditions. | ### DBS operation WLAN uses multiple Media Access Controls (MACs) available within the chipset to perform DBS scans. WCN6856 supports DBS, where a 2.4 GHz and a 5 GHz scan can occur simultaneously, or a scan channel can run in parallel with another Wi-Fi operation on a different band. The concurrent operation of two 802.11 MAC/Physical (PHY)/radio pipes on separate radio bands occur on 5 GHz, 6 GHz (PHY A) and 2.4 GHz (PHY B). ### Coexistence The 2.4 GHz industrial, scientific, and medical (ISM) band is used by Bluetooth®, Wi-Fi, and Mobile Wireless Standards (MWS) Long Term Evolution (LTE). The coexistence software reads the states of Wi-Fi, Bluetooth, and LTE to determine the coordination methodology that best meets the expectations on each link; such as Quality of Service (QoS) on Bluetooth links, and throughput on Wi-Fi.
