Chapter 5 Configuring the Client Adapter
Setting RF Network Parameters
Channel Specifies the frequency that your client adapter will use as the channel
for communications. These channels conform to the IEEE 802.11
Standard for your regulatory domain.
• In infrastructure mode, this parameter is set automatically and
cannot be changed. The client adapter listens to the entire
spectrum, selects the best access point to associate to, and uses the
same frequency as that access point.
• In ad hoc mode, the channel of the client adapter must be set to
match the channel used by the other clients in the wireless network.
If the client adapter does not find any other ad hoc adapters, this
parameter specifies the channel with which the adapter will start its
cell.
Range: Dependent on client adapter radio and regulatory domain
Example for 2.4-GHz client adapters:
1 to 11 (2412 to 2462 MHz) in North America
Example for 5-GHz client adapters:
36, 40, 44, 48, 52, 56, 60, and 64 (5180, 5200, 5220, 5240,
5260, 5280, 5300, and 5320 MHz) in North America
Default: Dependent on client adapter radio and regulatory domain
Example for 2.4-GHz client adapters:
6 (2437 MHz) in North America
Example for 5-GHz client adapters:
36 (5180 MHz) in North America
Note Refer to Appendix D for a list of channel identifiers, channel
center frequencies, and regulatory domains for each channel.
