Qisda S4CWM-11WS-B255C Bluetooth Wlan Antenna Device

INTRODUCTION

S4CWM-11WS-B255C is a Bluetooth/WLAN Antenna Device includes, PCB with BT/WLAN SoC AW690 with periphery and two conformal antennas. PCB and antennas are mounted inside of a plastic cover. The device is powered by single 3,3V voltage. A 1,8V switch regulator is on board of the device. Wi-Fi 6 and Bluetooth (BT) 5.2 are integrated into the used SoC NXP®AW690.

AW690 supports only SISO in CDW (Concurrent Dual Wi-Fi) application and MIMO in single band is still available. Supporting a MIMO configuration in 5GHz band, the System-on-Chip (SoC) implements advanced features including MU-MIMO, OFDMA and Target Wake Time (TWT). The device provides host interface for the Wi-Fi radios (PCIe) and Bluetooth radio (UART) with built-in 1V8 switch regulator which provide a flexible design for easy integration into demanding automotive applications.

Interface

Host Interface

• The device supports PCIe (Gen1) and high-speed UART as the host interfaces for connecting the WLAN and BLUETOOTH to the host processor.

Digital Audio Interface

• PCM interface supports continual transmission and reception of PCM data without processor overhead.
• The PCM clock rate from 64 kHz to 2.048MHz with multi-slot handshake and synchronization. PCM encoding/decoding support A-law, μ-law, and linear voice.

Configuration

• WLAN host interface of S4CWM-11WS-B255C only support PCIe and doesn’t support SDIO.
• To avoid wrong settings in CFG, device internally is configured default for PCIe. CFG1 and CFG2 is set to 1 by internal 10k Ohm pull-up resistor and CFG3 is set to 0 by internal 10k Ohm pull-down resistor. User does not require additional settings.

FCC STATEMENT

Federal Communications Commission (FCC) Statement

15.105(b)

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules.

Operation is subject to the following two conditions:

1. this device may not cause harmful interference.
2. this device must accept any interference received, including interference that may cause undesired operation.

15.21

• You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment.

FCC RF Radiation Exposure Statement:

1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated, keeping the radiator at least 20cm or more away from the person’s body.

For ISED

This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:

1. This device may not cause interference.
2. This device must accept any interference, including interference that may cause undesired operation of the device.

Caution: Exposure to Radio Frequency Radiation

1. To comply with the Canadian RF exposure compliance requirements, this device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter.
2. To comply with RSS 102 RF exposure compliance requirements, this equipment should be installed and operated, keeping the radiator at least 20cm or more away from the person’s body.

For CE

• Operation in 5150~5350MHz is restricted to indoor use only.

This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and your body.

FAQ

• Q: What host interfaces does the device support?
  • A: The device supports PCIe (Gen1) and high-speed UART as host interfaces for connecting WLAN and BLUETOOTH to the host processor.
• Q: How is the WLAN host interface configured?
  • A: The WLAN host interface of S4CWM-11WS-B255C only supports PCIe and is internally configured default for PCIe to avoid incorrect settings in CFG.
