Firstly, i'm sorry that my English skill is very poor.
Based on IEEE std 802.11 -2016 Part 11 : Wireless LAN medium Access Control (MAC) and Physical Layer (PHY) specifications , the RSSI parameter of the RXVECTOR parameters which is described in the Table 17.2 has maximum value for indicating the RSSI value in percentage(%) units. However, the spec does not decide the number of RSSI maximum, it depends on the manufacturer.
From ublox, I purchased the THEO-P173 which has the NxP saf510x chipset. And then I request them for acquiring the number of RSSI maximum, but they said that they cannot reply it because the PHY spec depends on NxP.
So, I request on this community for getting the RSSI maximum value to convert the RSSI value [%] of RXvector to [dBm] units.
And I found the datasheet of the cohda MK5 module using saf5100 chipset. In the datasheet, the range of RSSI measurements is described. If i know the RSSI maximum value, I can convert the RSSI value to dBm using the datasheet.
Thank you for your time. And Please help me for developing application.
