[color=#212121][size=medium][font=Times New Roman]we observe in certain environment a total loss of the signals, what can disturb the signals?
can you increase the signal strength.[/font][/size][/color]
[color=#212121][size=medium][font=Times New Roman]
[color=#212121][size=medium][font=arial, sans-serif]Let me explain:
I use channel 2,
currently the power is that of calibration: dwt_getotptxpower
if I force with the max values of the channel
0x15355575, // 16M prf power
0x07274767 // 64M prf power
will the result be better?
or if I use the values for channel 5
0x0E082848, // 16M prf power
0x25456585 // 64M prf power
what is the max value that I can put to have more power.
not to go further but to be less disturbed?
Thank you[/font][/size][/color][/font][/size][/color]
The TX power register is described in DW1000 User Manual,

Hi Charles,
The operating range varies depending on the channel centre frequency and channel bandwidth selected – a lower centre frequency gets more range than a higher one, while the wider bandwidth channels channel 4 and channel 7 have more range than the standard 500 MHz bandwidth channels as the wider channel allows more energy to be sent at a given dBm / MHz regulatory limit. (See IC user manual chapter 9 “Operational design choices when employing the DW1000”
To increase / adjust the power is discussed in the IC user manual and APS023 part 1 chapter 4 ADJUSTING & CALIBRATING TRANSMIT POWER IN THE DW1000

Hi Charles,
You can’t increase the Tx power too much or you will violate the UWB regulatory limit (-41.3 dBm/MHz).
Can you describe the environment in which you’re seeing loss of reception of the transmitted signals? E.g. are you trying to penetrate thick walls?
