Table 9: Transmit and receive power
All transmit and receive power levels are measured on the evaluation board. The values
already include losses of transitions from module to motherboard to SMA or modules PCB
antenna. They are realistic values for the end application.
Sensitivity in the table above is stated for the common used bit error rate of 0.1%. In the table
below the sensitivity is stated for a packet error rate of 1% with a payload length of 38 byte
at different data rates. The PER 1% is a harder criteria resulting in 2 dBm less sensitivity.
