Embedded Wi-Fi with TRENDnet

WALK IN THE PARK

By putting the Wi-Fi radio on the air, I’ve verified the basic functionality of the Wi-Fi API. Up to this point, only MAC-level operations between the Wi-Fi board and the AP have been executed. The next step is to integrate some tried and true UDP and TCP/IP routines that I wrote for wired embedded Ethernet devices into the Wi-Fi board’s firmware mix. That will put the IP side of the wireless session into play and then I’ll be able to make some meaningful user data flow across the wireless link. As you can see in the simplicity of the Wi-Fi board hardware, wireless design isn’t complicated, it’s embedded.
