| | 9 | The 802.11 DCF is responsible for many behaviors. These actions include (but are not limited to): |
| | 10 | |
| | 11 | * Acknowledging good receptions |
| | 12 | * Retransmitting failed transmissions |
| | 13 | * Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) |
| | 14 | * Binary Exponential Backoff (BEB) |
| | 15 | |
| | 16 | The purpose of this document is not to explain or defend every aspect of the DCF. Instead, this document is to aid in the understanding of how the standard DCF behavior is realized within the Mango 802.11 Reference Design. |
