s via the standards IEEE802.11a or IEEE802.11b/g. It is composed of: BWLC panel + WLAN mPCI card 2 IF antenna Panel antenna with suitable U.FL antenna cable IEEE802.11b:
IEEE802.11g:
IEEE802.11a:
IEEE802.11a/b/g There is only one firmware version for all countries
(it is adapted via the country selection in the menu) Client devices have to be equipped with an Ethernet connection. The BWLC module in the Ethernet device has to be operated in Ethernet Client mode. Only one wired Ethernet end device may be connected to the module. Encryption:
The following encryptions are available with BWLC:
- no encryption
- WEP 40 (64) /128 Bit
- WPA-PSK/TKIP, (WPA1 without Enterprise)
- WPA-PSK/AES CCMP, (WPA2 without Enterprise) Authentication Ad-Hoc mode IEEE802.11i (Personal (WPA, WPA2), IEEE802.1x (LEAP, EAP-TLS, EAP-TTLS, PEAP-GTC, PEAP-MSCHAP v2) Ad-Hoc operation with the BWLC module is only supported in IEEE802.11b and IEEE802.11g Mode!
In IEEE802.11a Mode the Ad-Hoc operation is not supported. Ethernet connection BWLC module Power Supply The Ethernet connection of the BWLC module is identified via auto MDI/MDIX. It therefore makes no difference whether a patch or a crossover Ethernet cable is used.

The connecting cables should never be installed outdoors. Version: 2d Page 5 of 17 BWLC User Manual 2 Configuration The module can be addressed and configured via the wired Ethernet interface and also via the wireless interface. Two options are available:
- WEB Browser (e.g. Internet Explorer Version >=5.5)
- Configuration tool (ESCG_Config version 3.21) Access to the BWLC module ESCG configuration tool ESCG_Config
(current version V3.21) Web browser
(e.g. Internet Explorer version >=5.5) Using this you can display the available BWLC modules (see note) The BWLC module is actually configured via the Web browser Start via ESCG_Config.exe Start via IP address of BWLC module Default IP address: 192.168.0.150 The "Web" button opens a Web browser with the corresponding BWLC IP address.
(only if the computer is located in the same network segment as the BWLC module) Note:
- If the computer (on which the ESCG_Config tool runs) is connected to the BWLC module directly via a wire Ethernet connection, you will only see the BWLC module that is directly connected. If the ESCG_Config-tool is accessed from a central location (i.g. via an AP) subsequently all the modules that are in reach are displayed Via the IP address of the BWLC module (standard IP address: 192.168.0.150) the homepage of the BWLC module is accessed. Note:
In a special configuration, this is achieved via the IP address of the connected device + port address (default 2153). Version: 2d Page 6 of 17 BWLC User Manual 2.1 Main menu item - Information Basic information on the module is displayed here. The following information is relevant in assessing the strength of the wireless signal being received:
- SNR
- Current channel
- Channel quality BWLC Bridge information BWLC Network settings BWLC Wireless settings SNR:(Signal Noise Ration). Ratio of wanted signal strength to noise. I.e. the greater the value, the easier it is to assess the wireless signal. The value should be 30 dB. Current channel:
The channel used by the module (frequency band)
(only information, as this is determined by the AP) This is required to assess channel quality Channel quality:
The BWLC module regularly scans the used ISM band. The value specifies the current quality of the signal. 100% corresponds to a completely free channel. At 60 % performance can be expected to be normal. At values of 30% regular data traffic can hardly be expected. Version: 2d Page 7 of 17 BWLC User Manual 2.2 Main menu item - APs This is where the Access Points that can be detected by the BWLC module are listed.

Version: 2d Page 17 of 17 Statements and instructions according to FCC and Industry Canada Rules 1. Information for host integrators of the radio module CAUTION:
Host integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral etc.). 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 host integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 1.1 Labelling instructions for host devices The FCC and IC ID are permanently fixed on a label on the module, and, if the identification numbers are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:
Contains Transmitter Module FCC ID: V98-BWLC-V1 Contains Transmitter Module IC: 7821A-BWLCV1 Any similar wording that expresses the same meaning may be used Additionally the two part statement must be fixes on the host device:
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. 1.2 RF Exposure / collocation requirements The fixed external antennas used for this mobile transmitter 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."
1.3 Information to end user End users may not be provided with the module installation instructions. For information to users, all relevant instructions that pertain to all components of a composite device are required. For example, Class A or Class B statements in Section 15.105; all warning statements and special instructions as required by Sections 15.21 and 15.27; and all Part 18 applicable instructions / attestations must be clearly stated. However, realistic variations in editing to clarify the language and structure are permitted as long as all the relevant points applicable to all of the components are represented. 2. FCC and Industry Canada warning statements and special instructions Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the authority to operate the equipment. 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 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. If the device is going to operated in 5.15 5.25 GHz frequency range, then is restricted in indoor environment only. Note: High power radars are allocated as primary users of the bands 5.25 5.35 and 5.65 5.85 MHz and these radars could cause interference and/or damage to Wireless - LAN devices.
