As Joel B pointed out, Wi-Fi traffic can be sniffed using software and remote PC. Wireshark is your friend. Please note, however, sniffing card should support promiscuous mode. Traffic can be sniffed locally as well. If your device is running embedded Linux, you can create a monitor interface and use tcpdump. Be aware, that sniffing Wi-Fi traffic using tcpdump will not give you all packets, because some control packets will be filtered out by firmware (but most likely you don't want them anyways, unless you are Wi-Fi driver developer). Also, monitor mode is not supported by all drivers. |

If you want to view over the air WiFi traffic (this is known as "sniffing"), the (somewhat) standard way of doing this is using a computer with a wireless adapter and monitoring software. The software should let you start capturing all traffic or filter out only certain traffic of interest to you. Then you can decompose packets in the software and see the various components of each packet. |
