| | 12 | '''PHY/MAC Hardware Changes:''' |
| | 13 | * Shifted Tx power settings from [-12,19] to [-9,21] |
| | 14 | * After a thorough characterization campaign, we changed a couple of default values for Tx parameters |
| | 15 | * BB gain now 1 instead of 2 |
| | 16 | * PA linearity is now 2 instead of 0 |
| | 17 | * Reduced default RSSI averaging from 8 samples to 4 for reduced delay |
| | 18 | * Added new RSSI packet detection logic that optionally can require both a minimum RSSI as well as minimum autocorrelation output before triggering the PHY to start. |
| | 19 | * Changed the precision of the energy_thresh register in the packet detection subsystem. Was UFix14_8 and is now UFix14_4 |
| | 20 | * Correspondingly, the default boot value of 150 (0.5859 in UFix14_18) is now 9 (0.5626 in UFix14_4) |
| | 21 | |
| | 22 | '''MAC Software Changes:''' |
| | 23 | * In addition to a signed 8-bit value for Rx power, the mpdu_info struct created by CPU_LOW now also contains the raw RSSI used in the calculation of Rx power |
| | 24 | * Fixed a capitalization issue in a few includes that would cause errors on case-sensitive filesystems |
| | 25 | * Raised default Tx power in all top-level projects to 15 dBm (previously 13 dBm) |
| | 26 | * Added a calibration value to the IPC_MBOX_SET_TIME mailbox command to account for the fact that it takes time to set the time. |
| | 27 | * Completely refactored Rx power calculation function based on lookup tables. |
| | 28 | * New Tx power-to-gain mapping function from characterization campaign |
| | 29 | |
| | 30 | '''wlan_exp Framework Changes:''' |
| | 31 | * Fixed a bug in the retrieval of promiscuous statistics. Previously, the only way to retrieve these promiscuous statistics was to retrieve all of them. The wlan_exp framework will now honor an optionally-supplied MAC address specifying a particular promiscuous stat struct that you want to retrieve. |
| | 32 | * Fixed an IBSS issue where Tx parameters (e.g. rate) would be ignored for stations that had not yet populated the station_info list at the IBSS node. |
| | 33 | |
| | 34 | '''Other Changes:''' |
| | 35 | * Added new [wiki:802.11/Benchmarks/Tx_Char Tx] and [wiki:802.11/Benchmarks/Rx_Char Rx] Characterizations. We're pleased to report that the Mango 802.11 Reference Design's transmitter and receiver exceed the requirements specified in the 802.11 standard. |
