1.2 CB3000 Operational Principles
To improve CB3000 management and performance, users need to understand basic network operating mode
functionality and configuration options. These topics are described in the following sections:
• CB3000 Network Operating Modes
• Media Access Control (MAC) Layer Bridging
• DHCP Support
• Modulation
• Web Management Support
• Wireless Security Support
1.2.1 CB3000 Network Operating Modes
The CB3000 can be configured to operate in two different modes depending on the needs of the network.
Select the CB3000 operating mode based on device interoperability requirements and network conditions
(DHCP support, security settings, etc.).
The CB3000 supports the following network modes:
• Infrastructure Mode
• Ad Hoc (Peer-to-Peer) Mode
1.2.1.1 Infrastructure Mode
In infrastructure mode, the CB3000 connects to a LAN through a wireless access point. Ethernet client devices,
such as PCs, printers, POS devices, and other Ethernet-capable devices connect to the CB3000, either directly,
or through a hub connection.
The CB3000 associates with a nearby access point and sees the network device combination as a standard
mobile unit (MU). The access point then forms a wireless bridge between the wired LAN and clients through
the CB3000.
The access point is a dedicated device wired into the LAN backbone, while the CB3000 can be physically
moved throughout the LAN. However, the CB3000 is designed to be placed in a single location for optimal use.
Ethernet clients connected to the CB3000 communicate within the network by routing data through the
associated access point. The 802.11 standard enables CB3000 supported clients to be moved from one location
to another. Reassociation occurs instantly on an open network with DHCP, but IP configuration is necessary for
the CB3000 to communicate within networks that have security settings applied.
