3.1.2 RF-Related Parameters
Wireless communication between the BHT terminals and access points that are connected to each other
by a wireless LAN are command-controlled by user programs.
For the setting procedure of RF-related parameters, refer to Section 2.5.4, "[3.4] RF Menu (Network
Interface Control)."
ESSID (Extended Service Set ID)
An ESSID is an ID that identifies the wireless network. Wireless devices having a same ESSID can
communicate with each other.
POWER
This parameter sets the power mode for the wireless module built in the BHT. The following six power
modes are available.
Power mode Power consuming state
Full Consumes much power.
Most*
More
Mid
Less
Least
Consumes less power. The BHT may take more time to establish
the wireless link or send response messages.
*Default
WEP (Wired Equivalent Privacy)
When WEP is ON, messages to be sent/received over the wireless LAN will be encrypted.
The WEP KEY uses 40-bit (10-digit hexadecimal) or 128-bit (26-digit hexadecimal) encryption word.
The BHT is able to definitely communicate with access points having the same WEP KEY.
AUTHENTICATE
This parameter sets up the authentication system to be applied when WEP is enabled. You can use
either one of the two KEYs—OPEN and SHARED KEY to disable and enable the authentication,
respectively. If WEP is disabled, choose OPEN so that communication is no longer possible.
WEP KEY
You can set four types of encryption keys (WEP KEY1 through WEP KEY4). If you enable WEP, choose
any one of WEP KEY1 through WEP KEY4 as TRANSMIT KEY.
