Note Each country has its own regulatory restrictions concerning electromagnetic
emissions and the maximum RF signal strength that can be transmitted.
Consequently, selecting a country different from the country you are actually
operating the CB3000 in results in the illegal operation of the CB3000.

To configure the CB3000 into an ad hoc network, see Configuring Ad Hoc Settings.
3.1.2.2 Configuring Ad Hoc Settings
Ad hoc mode is used to form peer-to-peer CB3000 networks without access points. Use ad hoc mode to create
networks within established network coverage areas or networks free of the physical constraints of access
point provided radio coverage areas. The device starting the ad hoc network (the first device transmitting a
beacon) determines the channel and data rate used for the other devices within the network using the same
ESSID.
Ad hoc mode is an Independent Basic Service Set (IBSS) mode requiring no backbone infrastructure. The lack
of an access point results in devices alternating the duty of sending beacons. There are no relay functions in
an Ad Hoc network, and not all mobile units are capable of communicating with other mobile units due to the
range limitations. Consequently, all stations need to be within range of each other.
Note The CB3000 must already be configured to run in ad hoc mode in order to set
data rates. If the unit is configured for infrastructure mode, the
Data Rate button is
disabled.
The CB3000 and its connected devices are required to use the same channel to interoperate. However, a
channel has restrictions based on the country of operation. Ensure the channel selected is appropriate for the
intended country of operation, or risk operating your CB3000 illegally.
To configure the CB3000 for AD Hoc operation:
1. Select Settings > Wireless Settings > WLAN Settings from the CB3000 menu tree.
2. For the Network Mode field, select Ad-hoc (Peer-to-Peer). The Ad Hoc Configuration screen
displays.
3. Configure the remainder of the fields, as appropriate, per the following descriptions.
•
ESSID (Wireless LAN Service ID) – Select from one of the following radio buttons:
•
Attach to any ESSID automatically – Enables the CB3000 to randomly select a target WLAN
for connection.
•
Specify the ESSID – Enables you to enter the name of a target WLAN or use the drop-down
menu to select an existing WLAN.
Click the “View”
Available Networks link to view the available networks first, if unsure of the
network options.
•
Frequency Band – Select either “a” or “b/g” for the 802.11 frequency band supported.
•
Channel Selection – Select from one of the following radio buttons:
•
Use default channel – Enables the CB3000 to use the default channel settings.
