In case, you have a TP-Link AX1500 Wi-Fi 6 Router Archer AX10 at home as shown in figure 2. So for identifying the free-space path loss, the parameters for the router are given in table 1 that are derived from the specifications of the device given in Table 2. i. You being a design engineer should calculate the distance at which this router can perform satisfactorily. Table 1: Parameters for TP-Link AX1500 Wi-FI 6 Router 1. Transmit Power 2. Reception Sensitivity 3. Transmit Grain 4. Receiver Antenna Gain 5. Transmitter & Receiver Antenna circuits losses Ltcdb & LrcdB PtdB =-66dBm for 11ac VHT20_MCS 3 dBi 3 dBi 3 dB Note: As you can notice that reception sensitivity is different for each standard. So group 1, should choose the first sensitivity i.e., 11a 54Mbps=-79dBm and group2 the second and so on.
