| | 12 | '''PHY/MAC Hardware Changes:''' |
| | 13 | * Fixed a Transmitter scaling issue with the 64-QAM rates. Outer symbols of the constellation were previously clipped and were therefore more prone to symbol errors. The fix improves Tx EVM for these rates by several dB. |
| | 14 | * Added a new register to prevent the PHY receiver from wrapping the address it uses to write bytes to the packet buffer. This prevents the PHY from overwriting early bytes in a packet when receiving packets longer than allocated space in the packet buffer. |
| | 15 | * Added an optional minimum packet detection power threshold. Details [wiki:802.11/Benchmarks/Pkt_Det_Min_Power_Char available here]. |
| | 16 | * Extended the duration of PHY debug outputs like LTS_Timeout and FCS_Good so they can be seen on a scope when zoomed out. |
| | 17 | * Fixed an issue with the Rx "Coded Bit Counter." Issue was identified in [http://warpproject.org/forums/viewtopic.php?pid=12369#p12369 this forum thread]. |
| | 18 | |
| | 19 | '''MAC Software Changes:''' |
| | 20 | * Reordered statistics processing in the AP/STA/IBSS projects so that stats are updated even for frames that are not addressed to the node that received the frame. |
| | 21 | * Fixed an IBSS issue that would populate the bcast MAC address into the list of associated stations. |
| | 22 | * Fixed an IBSS issue where a node would ignore the capabilities field in received beacons. This led to a problem where an IBSS node would mistake an infrastructure BSS (i.e. an AP) as a BSS it could join. |
| | 23 | |
| | 24 | |
| | 25 | '''wlan_exp Framework Changes:''' |
| | 26 | * Changed the API to [https://warpproject.org/docs/mango-wlan-exp/node.html#wlan_exp.node.WlanExpNode.set_tx_power set_tx_power] and [https://warpproject.org/docs/mango-wlan-exp/node.html#wlan_exp.node.WlanExpNode.get_tx_power get_tx_power]. |
| | 27 | * Added new command for [https://warpproject.org/docs/mango-wlan-exp/node.html#wlan_exp.node.WlanExpNode. configure_pkt_det_min_power configure_pkt_det_min_power]. |
| | 28 | * Fixed an issue with reading promiscuous statistics from a node when providing a specific MAC address. Previously, the board would only look for this MAC address within the list of associated stations instead of all promiscuous statistics. |
| | 29 | * Fixed an issue with the implementation of [https://warpproject.org/docs/mango-wlan-exp/node.html#wlan_exp.node.WlanExpNode.set_tx_rate_unicast set_tx_rate_unicast] and [https://warpproject.org/docs/mango-wlan-exp/node.html#wlan_exp.node.WlanExpNode.set_tx_ant_mode_unicast set_tx_ant_mode_unicast] when using the curr_assoc=True argument. The node will now correctly loop through all associated stations and make the necessary adjustment to the transmission parameters. |
| | 30 | |
| | 31 | '''Other Changes:''' |
| | 32 | * Added new characterizations of the [wiki:802.11/Benchmarks/Pkt_Det_Min_Power_Char Pkt_Det_Min_Power subsystem] |
