--

The 802.11 Reference Design and its documentation are under active development by the Mango team. The current release should be considered a beta- updates with bug fixes, API changes, new features and other refinements will be posted frequently. Please check the downloads page for the latest updates and post any questions about the design to the forums.

Station

The station implementation in the Mango 802.11 Reference Design can associate and communicate with 802.11 access points (WARP or otherwise). The source and sink of traffic for the station is Ethernet. Because an AP expects the wireless MAC address of each station to match collected clients,

Top-level view of STA States

There are three broad classes of events that pull the STA implementation out of an idle state. Those classes are:

  1. Wireless MPDU Receptions
  2. Ethernet Frame Receptions
  3. User Interaction Events

In our implementation, each of these state transitions occurs via an interrupt.
