Introduction
The WiBear11n industrial universal module is
targeted for integration into different OEM
products. The module is designed for both
simultaneous and independent operation of the
following: 802.11a/b/g/n payload data rates for
Wireless Local Area Network (WLAN), Bluetooth
3.0+High Speed (HS) and Bluetooth 2.1+EDR. It
provides a complete end-to-end solution for low-

Product Variants
Table 2: Product variants
Product Name Description
WiBear11n-SF1 Single band WLAN (802.11 b/g/n, 2.4 GHz only) and Bluetooth module. Module has one
joint antenna connector for WLAN and Bluetooth operation (see block diagram).
WiBear11n-SF1/-DF1 is recommended for cost effective AP solution, AP without or rare
Bluetooth traffic or cost effective station with one system antenna.
WiBear11n-SF2 Single band WLAN (802.11 b/g/n, 2.5 GHz only) and Bluetooth module. Module has
separated antenna connectors for WLAN and Bluetooth operation (see block diagram).
Overall performance (throughput) is maximized for AP mode with simultaneous Bluetooth
traffic. Two system antennas are required (one for WLAN and one for Bluetooth) with 30
dB or better isolation between antennas (orthogonal oriented antennas with more than
50…60 mm. distance between). May be recommended for higher performance of AP.
WiBear11n-DF1 Dual band WLAN (802.11 a/b/g/n, 2.5 and 5 GHz) and Bluetooth module with one joint
antenna connector for WLAN and Bluetooth. Similar to WiBear11n-SF1.
WiBear11n-DF2 Dual band WLAN (802.11 a/b/g/n, 2.5 and 5 GHz) and Bluetooth module which has
separated antenna connectors for WLAN and Bluetooth. Similar to WiBear11n-SF2.
Note: For maximum throughput during simultaneous WLAN (AP) and Bluetooth operation, the Bluetooth
Coexistence Arbiter (BCA) settings should be optimized by the host system software.

NOTES:
1
Possible to use as a LED output depend on firmware (driver) version. Regardless of the I/O supply
(1.8V or 3.3V), the supply to the actual board LED always need to use 3.3V on the other end of the
LED and works as open drain circuitry in that case. LED current limiting resistor should be used.
Maximum sink to the ground current - 10 mA.
2
Should be provided from external source in case of power save operation modes necessity. Not
required for full power mode and for automotive use (firmware & driver version 14.44). Mandatory
for all other releases with sleep mode support. Sleep clock signal requirements: frequency
32.768kHz ±250ppm, low level from 0 to 0.25V, high level from 0.8 to 2.0V, duty cycle 20-80%,
slew rate less than 100nS (10-90%).
3
Leave it unconnected when 32.768KHz Sleep Clock provided, pull down by 47K resistor for Sleep
Clock less operation.

Host Interfaces
SDIO Interface
WiBear11n module supports a SDIO device interface that conforms to the industry standard SDIO Full-Speed
specification and allows a host controller using the SDIO bus protocol to access the WLAN and Bluetooth
functions. The module also supports High Speed mode as defined in the SDIO 1.2 specification.
The module's SDIO host interface pins are powered from the VIO voltage supply.
A module acts as the device on the SDIO bus. The SDIO interface supports SDIO modes at the full clock range
of 0 to 50 MHz which allows a maximum throughput of 200Mbps.

Reference Design
Overview
Reference design shows how to connect a WiBear11n module to the host controller. WLAN and Bluetooth
(BT3.0 HS + EDR) may be connected to the host simultaneously over the SDIO bus. The layout is equipped
with the possibility to either use an onboard antenna or an external antenna connected via coaxial connector by
means of setting of jumper R7 or R8. Host interface voltage can also be changed by jumper J6. The ready-
made reference design is available as WiBear11n Evaluation Kit from Lesswire AG.

Mounting process
The WiBear11n is a surface mount module supplied on a 6-layer FR4-type PCB with gold plated connection
pads and produced in a lead-free process with a lead-free soldering paste.
Modules rated at moisture sensitivity level 3. See moisture sensitive warning label on each shipping bag for
detailed information. After opening the dry pack, modules must be mounted within 168 hours in factory
conditions of maximum 30°C/60%RH or must be stored at less than 10%RH. Modules require baking if the
humidity indicator card shows more than 10% when read at 23±5°C or if the conditions mentioned above are
not met. Please refer to J-STD-033B standard for bake procedure.
Module is compatible with industrial reflow profile for RoHS/Pb-free solders, Sn96.5/Ag3.0/Cu0.5 solder is a
right choice. Use of "No Clean" soldering paste is strongly recommended, cleaning the populated modules is
strongly discouraged - residuals under the module cannot be easily removed with any cleaning process.
Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board
and module. The combination of soldering flux residuals and encapsulated water could lead to short circuits
between neighboring pads.
Only a single reflow soldering process is encouraged for host boards with WiBear11n modules.
The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency
of the oven and particular type of solder paste used. Since the profile used is process and layout dependent,
the optimum profile should be studied case by case. Recommendations below should be taken as a starting
point guide. In case of basic information necessity please refer to J-STD-020C standard.

Installation and Regulatory Information
General
The purpose of this guide is to explain how to integrate the WiBear11n module into the end product. The
module has to be installed and used in accordance with the technical instructions provided by the
manufacturer. The module may only be implemented in the configuration that was authorized. Note that any
modifications of this equipment not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.
European Union Regulatory Compliance
The WiBear11n module has been tested and complies with the regulatory standards EN 300 328 and EN 301
489-1/-17. We declare that the human exposure of this module is below the SAR limits specified in the EU
recommendations 1999/519/EC.
IMPORTANT: The ‘CE’ marking must be affixed to a visible location on the OEM product, where this module is
installed in, and has to be labeled in accordance to R&TTE Directive 1999/5/EC.
FCC Compliance
This device complies with Part 15 of the FCC Rules
1
. 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.
Not authorized modification could void authority to use this equipment.
The internal / external antenna(s) used for this module must provide a separation distance of at least 20 cm
from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
NOTE: The outside of final product that contain a WiBear11n module must display in a user accessible area a
label referring to the enclosed module. This exterior label can use wording such as the following: “Contains
Transmitter Module FCC ID: PV7-WIBEAR11N-SF1”
2
or “Contains FCC ID: PV7-WIBEAR11N-SF1”.
IMPORTANT: The approval type for the WiBear11n variants is a limited modular approval due to the absence
of a shielding. This requires any manufacturer of original equipment containing the WiBear11n module to ask
for an approval of their design by the manufacturer of the WiBear11n module.
IC Compliance
This device complies with Industry Canada RSS-210 (Rev. 8). 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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.
The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not
emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable
from Health Canada.
Not authorized modification could void authority to use this equipment.
