802.11/Usage/STA
v2 v3 3 3 = Using the 802.11 Reference Design: STA Application = 4 4 5 == STA User IO == 5 == Ethernet == 6 The STA uses ETH A as its source and sink for all wireless data packets. The STA code assumes a single Ethernet device is connected to ETH A, such as a PC or network camera. The STA code bridges the wired and wireless interfaces, translating between the wired device's MAC address and the WARP ndoe's wireless MAC address. This translation will not work if multiple Ethernet devices are connected to the STA node's ETH A interface via a switch. 7 8 The STA uses ETH B for interaction with the [wiki:../../wlan_exp experiments framework]. 9 10 == User IO == 6 11 7 12 '''Hex Displays''': the STA uses the hex displays to show the node's current association ID (AID) as assigned by the AP during the association handshake. The displays will change in real time as the station joins and leaves networks. The displays will show 00 when the STA is not associated with an AP (0 is not a valid AID). … … 9 14 '''DIP Switch''': the STA uses the left-most switch to enable or disable active scan for wireless networks on at boot. When the switch is up the STA will not attempt to join the default SSID at boot. The STA can still be associated with an AP via wlan_exp commands. This mode is very useful for running experiments with networks of WARP nodes (some AP, some STA) without allowing associations from non-WARP devices. 10 15 11 == STAUART ==16 == UART == 12 17 13 18 Refer to the [wiki:../UART UART usage] page for an overview of how the 802.11 design uses the UART cores on each CPU.
