2. General Concepts
2.1 Configuration Methods
The Wireless Bridge supports four main methods for setting and configuring the module:
1. Smart mode
Use the buttons and LED’s on the Wireless Bridge to automatically set up the most common use
cases.
2. Web interface
An online web interface with the most common settings for the Wireless Bridge.
3. AT commands
Connect to the Wireless Bridge over Ethernet using TCP, or directly on Layer 2 and use a terminal such as Hyperterminal to issue AT commands. This method is mainly for more advanced settings and use cases, and is not described in this document. All commands available in the web
interface and much more are supported throught the use of AT commands.
4. The SNMP protocol
This will not be used or described in this document.
2.2 Using SMART Configuration Mode
If the Mode button is pressed within 5 seconds from power up, the Wireless Bridge will enter SMART
configuration mode. The LED’s above the button (A, B, C, and D) will show the mode currently selected. When the required mode is selected, it must be confirmed by holding in the Mode button for two
seconds. This will cause the LED’s to start flashing during the operation of the selected mode.

"Enable DHCP server" can be used to easily access the Wireless Bridge if the PC is using DHCP, without having to change the PC’s IP settings. This mode should only be used when the PC is connected
directly to the module, and not if the module is connected to a network using a DHCP server. Enable
this mode, then connect the Ethernet cable to the computer. The DHCP server will stay enabled until
a reboot.
How to use the other different modes for specific use cases is described later in this document.
2.2.1 Using the Web Configuration Interface
By default, the Wireless Bridge has the following static IP settings;
•
IP address: 192.168.0.99
•
Subnet mask: 255.255.0.0
•
Default gateway: 192.168.0.99.
To access the module using the web-based configuration interface, the computer must be set up in the
same network, e.g. IP address: 192.168.0.1 and subnet mask: 255.255.0.0.
Open a web browser and enter http://192.168.0.99 in the address field. From here, the most common
configuration parameters needed to set up a connection can be found.

General Concepts 12
2.2.2 Reset to Factory Defaults
It is possible to reset to the factory default settings in 4 different ways:
•
Enter and confirm SMART mode 2.
•
Issue AT&F.
•
Hold the Mode button while the Wireless Bridge is starting. Note: Ensure that the Ethernet cable is disconnected, and that any firmware update program has been stopped.
•
Press the Restore Device button in the AT-commands section.
2.2.3 Wireless LAN Modes
A Wireless LAN network can be set up in two main connection modes:
•
Ad-hoc mode
This is typically used when two WLAN devices connect to each other without going via a WLAN
Access Point. In ad-hoc mode, only 802.11b transmission speeds are used, i.e. a maximum of 11
Mbit/s. The only encryption method supported is WEP.
•
Managed (or Infrastructure) mode
This is typically used when a group of devices are connected through a common WLAN Access
Point. In this mode, all available transmission speeds can be used, up to a maximum of
54 Mbit/s. This also allows for user selection of encryption and authentication methods to use.
This means that use cases supporting Managed mode normally have higher throughput.
2.2.4 Wireless Bridge Modes
There are three main Wireless Bridge modes supported by the Wireless Bridge, and these are referred to
in all the use cases described later in this document.
1. Ethernet Bridge mode
In this mode, which is supported only between two Wireless Bridges, the Ethernet packages are
encapsulated in UDP packages and transferred transparently between the two modules. Devices
on both sides of the wireless link are completely unaware of the wireless connection.
2. Client mode
In this mode the Wireless Bridge acts as a wireless extension of the wired Ethernet device it is
connected to. The module is configured to take over (clone!) the MAC address of the connected
device. This means that only ONE Ethernet device can be connected to each module, and not
an Ethernet network with several devices connected through an Ethernet switch or hub. In
"Client Mode", the Wireless Bridge cannot be accessed over the Wireless LAN interface. However, if the Ethernet link is lost, the module will temporarily enter "Multiclient mode" and can
then be accessed again. When the Ethernet link is re-established, the module will revert to "Client
Mode".
3. Multiclient mode
In this mode, the Wireless Bridge acts as in Client mode, but with the addition that multiple devices using the IP layer can be connected.
Ethernet Bridge mode will introduce an extra overhead (because of the encapsulation) and will have a
significantly lower throughput than Client/Multiclient mode.

2.2.5 WLAN Security
The Wireless Bridge supports various authentication and encryption methods. The following authentication methods are supported:
•
Open connection
•
Shared secret
•
WPA and WPA2 Preshared key
•
LEAP
•
PEAP
The following encryption methods are supported:
•
No encryption
•
WEP64
•
WEP128
•
TKIP
•
AES/CCMP
The following table shows valid combinations of authentication and encryption methods (x means valid
configuration):
No encryption

Open connection Shared secret
x
x
x
x
x
WPA/WPA2 PSK
LEAP
PEAP
x (WPA)
x (WPA2)
x
x
x
x
x
There are a few important considerations that also need to be addressed. If selecting WPA/WPA2 PSK
and TKIP, this is considered to be a WPA connection. If selecting WPA/WPA2 PSK and AES/CCMP,
a WPA2 connection is assumed. It is not possible to have WPA with AES/CCMP encryption.
To use LEAP or PEAP as the authentication algorithm, ensure that the access point supports this, as
not all do. Neither LEAP, PEAP nor WPA/WPA2 PSK will work in ad-hoc mode.
Note: Some access points have support for a combination of WPA and WPA2, as well as AES/CCMP
and TKIP. These options are not supported by the Wireless Bridge.

General Concepts 14
Key Management
For WEP64 and WEP128, shared keys can be entered in all four possible slots made available by the
AT*AGFPWI Write Encryption/Authentication Key (with Index) command. However, for LEAP,
PEAP and WPA/WPA2 PSK, the password or PSK must be entered in the key slot with index 1 (one).
This key must also be the one currently set as active by the AT*AGAFP Active Encryption/Authentication Key command.
If using LEAP or PEAP, the username for the Radius server should be entered with the command
AT*AGUN Username, and the domain with command AT*AGDN. For PEAP, the certificate must
also be considered. When receiving the certificate from the Radius server, the SHA-1 fingerprint is calculated and stored in the WEPA for future comparisons. If the certificate changes, or if a different Radius server is to be used, the new fingerprint must be entered, or the old must be cleared with the
command AT*AGCFP.
If using WPA/WPA2 PSK, it is possible to enter either the preshared key (i.e. the hexadecimal string)
or the password (plain-text), commonly referred to as “WPA-PSK” or “WPA-PWD”. When entering a
password (not a hexadecimal string), the Wireless Bridge will take a few seconds longer during the next
connection after this change, in order to deduce the real key from the password. The module will be
unresponsive while calculating the real key.
By default, the key is entered as an ASCII string. To enter a hexadecimal key, the bytes must be escaped
with the '\' character, e.g. to enter the string "12345" as hexadecimal, the following would be entered:
"\31\32\33\34\35"

This use case describes two Wireless Bridges connected in Client mode. Only one Ethernet device can
be connected to each of the modules. This use case will have higher performance than using the Ethernet Bridging case (no encapsulation of the Ethernet packages required).
3.4.2 Set Up the Use Case
This use case can be set up by using the SMART button and supports ad-hoc mode only.
1. Power on the first module. Enter SMART configuration mode 4 (wait for automatic configuration).
2. Power on the second module. Enter SMART configuration mode 5 (initiate automatic configuration).
3. Wait for the modules to connect and restart.
4. Use SMART mode 11 on each of the modules, to learn the MAC address of the connected device
(Client mode).
Note: This mode required that the device spontaneously sendd Ethernet data on the Ethernet
link. If this not is possible, use the web interface. See section “Using the Web Configuration Interface” on page 10 to set up the MAC address manually.
To set up this use case manually, follow these steps:
1. Power on the first Wireless Bridge and enter the web configuration.
2. Enter the SSID for the wireless network.
3. Select Operational mode "Ad-Hoc" and select a channel to use, based on the regional domain
settings.
4. Select Security Mode: The options available in ad-hoc mode are: "None", "WEP64" or
"WEP128".
5. If a security option was selected, now enter a key.
6. Under Client Mode, select Client Mode and set "WLAN MAC Address" to the MAC address
of the module it will be connected to via the wired connection.
7. Click "Write Wireless LAN Settings". Click "Reboot Device".
8. Power on the second Wireless Bridge and enter the web configuration.
9. Repeat 2, 3, 4 and 5 above. These values MUST be identical to the ones entered for the previous
module.
10. Repeat step 6 above. The "WLAN MAC Address" must be set to the MAC address of the device
it will be connected to via the wired connection.
11. Click "Write Wireless LAN Settings". Click "Reboot Device".
All Ethernet packets will now be tunneled between the two Ethernet segments.

3.12 Multiclient Mode
3.12.1 Overview
Multiclient mode is used when there is a need to have several devices (3 and 4 in figure above) behind
the Wireless Bridge that communicates with 1 and/or 2. The restriction is that only one device (3 or 4
in the example) can use Layer-2 communication, while the others need to use the IP layer. The Wireless
Bridge must also be configured on the same IP subnet as the other devices.
For devices to use DHCP over the Wireless Bridge connection while in Multiclient mode, the built-in
DHCP relay can be switched on with AT*ANDHCP, to ensure that all packets are forwarded correctly.
In this case, "DHCP Client and DHCP Relay" is recommended.
3.12.2 Set Up the Use Case
Multiclient mode is configured with AT*ACEW. If no Layer-2 communication is required, the MACaddress for AT*ACEW can be set to the Ethernet MAC-address of the Wireless Bridge.
