Once the PC or notebook is set up, we're ready to communicate. You can use Telnet or a
Web browser such as Internet Explorer, which come with most Windows installations, to
use the network interface, and you can use HyperTerminal to view the serial port when
these are called for in some of the later sample programs.
Now we’re ready to run the sample programs in the Dynamic C
folder. The sample programs should run as is in most cases.
6.2.4 Wi-Fi Sample Programs
The sample programs in Section 6.2.4.1 show how to set up the country- or region-specific
attributes, but do not show the basic setup of a wireless network. The sample programs in
Section 6.2.4.2 show the setup and operation of a wireless network — the
sample program is ideal to demonstrate that the RCM4400W has been hooked up correctly
and that the Wi-Fi setup is correct so that an access point can be found.
6.2.4.1 Wi-Fi Operating Region Configuration
The country or region you select will automatically set the power and channel require-
ments to operate the RCM4400W module. The following three options are available.
1. Country or region is set at compile time. This option is ideal when the end device is
2. Country or region is set via the 802.11d feature of the access point. This option uses
3. Country or region is set at run time. This is a convenient option when the end devices
These options may be used alone or in any combination. The three sample programs in the

will be deployed in multiple regions. A serial user interface would allow the RCM4400W
module to be configured via a Web page. Systems integrators would still have to make
sure the end devices operate within the regulatory requirements of the country or region
where the units are being deployed.

The country or region you select will automatically set the power and channel require-

NOTE: This option sets the power limit for RCM4400W to the maximum level permitted
in the region or the capability of the RCM4400W, whichever is less. Since the beacons
are being sent continuously, the wifi_ioctl WIFI_TX_POWER function cannot be
used with this option.
