CHAPTER 1. MODULE OVERVIEW
The Foxconn WBUR56 is a highly integrated module that support 2-stream 802.11ac
solutions with Multi-user MIMO with WLAN USB2.0 network interface controller. It combines a
WLAN MAC, a 2T2R capable WLAN baseband, and RF in a single module. The WBUR56 provides a
complete solution for a high-performance integrated wireless and Bluetooth device.
For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code
Keying (CCK) and OFDM baseband processing are included to support all IEEE 802.11b, 802.11g
and 802.11a data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK
with data scrambling capability are available, and CCK provides support for legacy data rates, with
long or short preamble. The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM,
64QAM and 256QAM modulation of the individual subcarriers, and rate compatible coding rate of
1/2, 2/3, 3/4, and 5/6, provide up to 866.7Mbps for IEEE 802.11ac MIMO OFDM.
1-1 Key Characteristic
IEEE 802.11 a/b/g/n and 802.11ac draft compliant
Support 20MHz, 40MHz, 80MHz in 5GHz band, and 20MHz, 40MHz bandwidth in 2.4GHz band
Dual-band 2T2R mode with data rate up to 867Mbps
Integrated LNA, PA
Security support for WPA/WPA2/WAPI
Complies with USB 2.0 for WLAN and BT controller

CHAPTER6: REGULATORY STATEMENT
FCC Statement:
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.
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 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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment. This transmitter must not be
co-located or operating in conjunction with any other antenna or transmitter.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
This device meets all the other requirements specified in Part 15E, Section 15.407 of the FCC Rules.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
and 2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further transmitter test will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed

WBUR56 PRODUCT SPECIFICATION September 23, 2021
FOXCONN CONFIDENTIAL 20
This preliminary specification is subject to change without notice.
Copyright © 2017 Hon Hai Precision Ind Co., Ltd. All rights reserved
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or co-
location with another transmitter), then the FCC authorization is no longer considered valid and the
FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be
