3.2 Ad-Hoc Mode
The ad-hoc mode allows you to create a less-structured community of wireless devices.
No wired or preexisting network is needed. No access point is needed. The wireless
devices simply communicate with each other. However, it is difficult (and outside the
scope of this manual) to connect an ad-hoc network to other networks (such as the Internet).
Ad-hoc networks are most useful for a group of devices that only need to communicate with
each other.
Figure 13. Ad-Hoc Wi-Fi Network
As for the infrastructure mode, a name (the SSID or Service Set Identifier) must be
assigned for the ad-hoc network. For a Rabbit-based Wi-Fi network, this name is distinct
from the infrastructure SSID, and is referred to as the
OWNSSID
in the sample programs
and in the software drivers.
A channel must also be specified. In the infrastructure mode, wireless clients detect the
channel automatically, but the clients must all be configured to agree on a specific channel
when they are being configured in the ad-hoc mode. This channel number may be any-
thing from 0–14, but local regulations in your country may restrict which channels may be
assigned. For example, only channels 1–11 are allowed in the United States.
Wireless encryption (WEP) may also be used as in the infrastructure mode. All wireless
devices on the network operating in the ad-hoc mode must be programmed with the same
encryption key.
