50180227-001RFSOM WBT, SOM MODULE, WIFI 802.11AC BT 5.0 – ROW

This HWB11AC-PRT module is a Wi-Fi/BT system on the module which will be placed inside the Honeywell products like printers, barcode scanners, RFID readers etc. To enable wireless connectivity. This module includes MAC & a physical layer of 802.11a/b/g/n/ac and the Bluetooth modem.
This module operates on a 5.0V DC Power supply with internal onboard regulation to generate 3.3v for powering ON all the circuits. The entire RF circuit is enclosed in an RF shield of dimension 25mm X 25mm.
The module uses an internal power amplifier and LNA for the 2.4GHz frequency band and an external front end chip for the 5GHz frequency band. All filters and diplexers are included in the module to ensure maximum power flatness and optimum VSWR. The module has one antenna chain for 1X1 output.
The module supports a range of data rates from 1Mbps in 802.11b mode to MCS9 in 802.11ac mode. This chipset also supports the concurrent operation of Bluetooth (Version5.0) for wireless connectivity during browsing or other device applications. Along with both standard and high speed (HS) Bluetooth data rates, Bluetooth low energy modes are also supported. Hardware WAPI acceleration engine, AES, TKIP, WPA and WPA2 are supported to provide the latest security requirement on your network.
The Device communicates with HOST using the SDIO interface for WIFI and UART interface for BLUETOOTH.

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. However, there is no guarantee that interference will not occur in an installation. If this equipment does cause harmful interference to radio or 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 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, and 2) This device must accept any interference received, including interference that may cause undesired operation.
Caution:
MODIFICATION:
 Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to operate the device.
INSTALL & OPERATION: The equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body.
Industry Canada
Model: HWB11AC-PRT
IC: 1693B-HWB11
This device complies with Industry Canada RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Note:
Within the 5.15 to 5.25 GHz band, UNII devices will be restricted to indoor operations only.
Labelling Guidelines for Products
The proposed FCC IC label format is to be placed on the module. If it is not visible when the module is installed into the system, “Contains FCC ID: HD5-HWB11, Contains IC:1693B-HWB11” shall be placed on the outside of the final host system.
