• WPA3 security not supported in AP mode. WPA3 STA supports both H2E and Hunting-and-pecking for WPA3 authentication. It picks authentication algorithm based on AP's capability. WPA3 STA supports PMKSA caching. If STA has valid PMKID (generated after first connection) with an AP it will trigger OPEN authentication for successive connection attempts. By default the lifetime for PMKSA entry is 12 hours. In WPA3 Personal Transition Mode if both WPA2 and WPA3 APs are available in scan results, STA will pick the AP which has strongest RSSI (it could be either WPA2 or WPA3). If connected WPA3 AP enables Transition Disable Indication, from that moment onwards STA in transistion mode will not try connections to WPA2 APs. This behavior will persist until reset of the STA.

Power save modes description#

• Power Save Mode 0 In this mode, module is active and power save is disabled. It can be configured any time, while the module is configured in Power Save mode 2 or 8.

• Power save Mode 1 Once the module is configured to power save mode 1, it wakes up periodically based upon the DTIM interval configured in connected AP. In power mode 1, only the RF of the module is in power save while SOC continues to work normally. This command has to be given only when module is in connected state (with the AP). After having configured the module to power save mode, the Host can issue subsequent commands. In power save mode 1 the module can receive data from host at any point of time but it can send/receive the data to/from remote terminal only when it is awake at DTIM intervals.

• Power Save Mode 2 Once the module is configured to power save mode 2, it can be woken up either by the Host or periodically during its sleep-wakeup cycle. Power Save mode 2 is GPIO based. In case of GPIO based mode, whenever host wants to send data to module, it gives wakeup request by asserting UULP GPIO #2. After wakeup, if the module is ready for data transfer, it sends wakeup indication to host by asserting UULP GPIO #3 or UULP GPIO #0. Host is required to wait until module gives wakeup indication before sending any data to the module. After the completion of data transfer, host can give sleep permission to module by de-asserting UULP GPIO #2. After recognizing sleep permission from host, module gives confirmation to host by de-asserting UULP GPIO #3 or UULP GPIO #0 and again goes back to its sleep-wakeup cycle. Module can send received packets or responses to host at any instant of time. No handshake is required on Rx path.

• Power Save mode 3 Power Mode 3 is message based power save. In Power Mode 3, both radio and SOC of RS9116-WiSeConnect are in power save mode. This mode is significant when module is in associated state with AP. Module wakes up periodically upon every DTIM and gives wakeup message ("WKP") to host. Module can not be woken up asynchronously. Every time module intends to go to sleep it sends a sleep request message ("SLP") to the host and expects host to send the acknowledgement message ("ACK"). Host either send acknowledgement ("ACK") or any other pending message. But once ACK is sent, Host should not send any other message unless next wakeup message from module is received. Module shall not go into complete power-save state, if ACK is not received from host for given sleep message. Module can send received packets or responses to host at any instant of time. No handshake is required on Rx path.

• Power Save mode 8 In Power save mode 8, both RF and SOC of the module are in complete power save mode. This mode is significant only when module is in un-connected state. Power Save mode 8 can be GPIO based. In case of GPIO based, host can wakeup the module from power save by asserting UULP GPIO #2. After wakeup, if the module is ready for data transfer, it sends wakeup indication to host by asserting UULP GPIO #3 or UULP GPIO #0. Host is required to wait until module gives wakeup indication before sending any data to the module. After the completion of data transfer, host can give sleep permission to module by de-asserting UULP GPIO #2. After recognizing sleep permission from host, module gives confirmation to host by de-asserting UULP GPIO #3 or UULP GPIO #0 and again goes back to its sleep-wakeup cycle. Module can send received packets or responses to host at any instant of time. No handshake is required on Rx path.

• Power save mode 9 In Power Mode 9 both Radio and SOC of RS9116-WiSeConnect are in complete power save mode. This mode is significant when module is not connected with any AP. Once power mode 9 command is given, the module sends ("SLP") request to host and wait for the ("ACK") from host and goes to sleep when ACK is given by host. Timer starts when power save command is issued and it can be configured by host using rsi_wlan_set_sleep_timer API. If host does not set any sleep time, then the timer is configured for 3sec by default. Upon wakeup module sends a wakeup message to the host and expects host to give ACK before it goes into next sleep cycle. Host either send ACK or any other messages but once ACK is sent no other packet should be sent before receiving next wakeup message. When ulp_mode_enable is set to '2', after waking up from sleep, the module sends WKP FRM SLEEP message to host when RAM retention is not enabled. After receiving WKP FRM SLEEP message, host needs to start giving commands from beginning (opermode) as module's state is not retained. Returns

Note

• 1. This frame has to be used by customers who has done FCC/ETSI/TELEC/KCC certification with their own antenna. All other customers should not use this. Inappropriate use of this frame may result in violation of FCC/ETSI/TELEC/KCC or any certifications and Silicon labs is not liable for that

• Internally firmware maintains two tables : Worldwide table & Region based table. Worldwide table is populated by firmware with Max power values that chip can transmit that meets target specs like EVM. Region based table has default gain value set.

  1. When certifying with user antenna, Region has to be set to Worldwide and sweep the power from 0 to 21dBm. Arrive at max power level that is passing certification especially band-edge.

  2. These FCC/ETSI/TELEC/KCC Max power level should be loaded in end-to-end mode via WLAN User Gain table. This has to be called done every boot-up since this information is not saved inside flash. Region based user gain table sent by application is copied onto Region based table .SoC uses this table in FCC/ETSI/TELEC/KCC to limit power and not to violate allowed limits. For Worldwide region firmware uses Worldwide table for Tx. For other regions(FCC/ETSI/TELEC/KCC), Firmware uses min value out of Worldwide & Region based table for Tx. Also there will be part to part variation across chips and offsets are estimated during manufacturing flow which will be applied as correction factor during normal mode of operation.

                                  The following are the regions and the values to be passed instead of macros in the example.
                                  Region      |          Macro Value

           3. <CHANNEL_CODE_2G> is a 8 bit value which is encoded as:
              If TX powers of all the channels are same, then use CHANNEL_CODE_2G as 17. In this case, mention channel number as 255.
              Tf TX power is not same for all channels, then indicate CHANNEL_CODE_2G as no-of channels. And specify tx power values for all the channels indicated.
           4. <CHANNEL_CODE_5G> is a 8 bit value encoded as number of rows in a region for 5G band.
               a. 5G is divided into 4 sub bands: 
                     band 1: channel number <= 48 
                     band 2: channel number > 48 and channel number <= 64 
                     band 3: channel number > 64 and channel number <= 140
                     band 4: channel number > 140
               b. If any channel in a band has different set of power values, specify the channel number followed by power values. 
               c. If all the channels in a band 1 has same power values, specify the band number as 1 followed by power value. 
               d. If all the channels in a band 2 has same power values, specify the band number as 2 followed by power value. 
               e. If all the channels in a band 3 has same power values, specify the band number as 3 followed by power value. 
               f. If all the channels in a band 4 has same power values, specify the band number as 4 followed by power value.
