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.

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.

WiBear11n Data SheetVersion 1.10 Copyright © 2013 lesswire AG www.lesswire.com Page 16 of 19 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. Table 16: Recommended reflow profile Profile feature Sn-Pb eutectic (Sn63/Pb37) RoHS/Pb-free (Sn96.5/Ag3.0/Cu0.5) Ramp up rate (TSMAX to TP) 3°C/sec max 3°C/sec max Minimum soak temperature (TSMIN) 100°C 150°C Maximum soak temperature (TSMAX) 150°C 200°C Soak time (ts) 60 - 120 sec 60 - 180 sec Liquidus temperature (TL) 183°C 217°C Time above TL (tL) 60 - 150 sec 60 - 150 sec Peak temperature (TP) 215 - 225°C 235 - 245°C Time within +0 / -5°C of actual TP (tp) 10 - 30 sec 20 - 40 sec Ramp down rate 6°C/sec max 6°C/sec max Time from 25°C to TP 6 min max 8 min max Note: lowest value of TP and slower ramp down rate (2 - 3°C/sec) is preferred.

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 Rules1. 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. 1 Limited modular approval has been applied for the module variant WiBear11n-SF1, the certification process for the other module variants is ongoing. 2 FCC and IC IDs for the WiBear11n module variants are shown in Table 18. Select the applicable ID.

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 IC ID: 7738A-WB11NSF1”2 or “Contains IC ID: 7738A-WB11NSF1”. IMPORTANT: The approval type for the WiBear11n variants is a limited modular approval due to the absence of a shielding. Due to Industry Canada Modular Approval Requirements (Source: RSS-Gen / Issue 3 / Dec. 2010) any application which includes the WiBear11n module must be approved by the module manufacturer (lesswire AG). The application manufacturer must provide design data for the review procedure. Approved Antennas List The module has been tested and approved for use with the antenna listed in the table below. Table 17: Approved antennas list Model Name Manufacturer and description Gain [dBi] 2450AT45A100 Johanson Technology, Chip antenna, 2400 – 2500 MHz 3.0 (peak) The module may be integrated with other antennas which the OEM installer must authorize with respective regulatory agencies and after approval of the module manufacturer.
