Getting Started
2.4.5.7 Channel
The frequency band allocated to 802.11 wireless communications is subdivided into different channels to
allow subnetworking. Your SCS needs to know which channel it should use for communications—the
channel will be the same as the one being used by the local AP. The default setting, Any, causes the SCS to
use the same channel used by the strongest AP with the same ESSID.
For infrastructure network mode, you should set the channel to Any so that the SCS can synchronize with
an AP. For Ad-Hoc network mode, you should set a specific channel number so that the SCS can start a new
IBSS if needed. When the channel is set to Any, the SCS can only join an existing IBSS.
Local>> DEFINE 80211 CHANNEL 7
Local>> SET 80211 RESET
2.4.5.8 WEP
Some 802.11 cards can be set with a WEP key, which will encrypt any data you transmit through wireless
communication. To enable WEP, enter the following command:
Local>> DEFINE 80211 WEP ENABLED
Local>> SET 80211 RESET
When WEP is enabled and a WEP key is set, the SCS will only connect to an AP (in infrastructure mode)
or communicate with other ad-hoc peers (in ad-hoc mode) that have been programmed with the same WEP
key as the SCS. For a key to match, both the key data and the index number must be identical.
Enter a WEP key if you have not previously done so. The key can be either 40-bits or 128-bits. Each key is
also assigned an index number, which is an integer between 1 and 4.
The SCS will receive both encrypted and unencrypted traffic. You can disable the reception of unencrypted
traffic and accept only frames encrypted with its WEP key by entering the following command:

Local>> DEFINE 80211 WEP RECEIVE ENCRYPTED
Local>> SET 80211 RESET
