I originally calculated the distance between 0.45 times the wavelength of UWB channel 5 to be 22.769mm, but I later discovered that the correct value is 20.788mm. This can be calculated using the formula (299792458 / 6489.6 * 10^6) * 100 * 10 * 0.45. I realize now that I may have made an error in my initial calculation, perhaps due to fatigue. Can you confirm if my new calculation is correct?
Also, I made the pcb and it is quite off, if I want to use PDoA gui, do I have to rewrite some of the code like get getDlist?
I mean Can anyone confirm my calculation, it was a typo.
Also, I conducted tests on UWB channel 9 and found that it yielded better results, albeit with occasional frame drops. If I decide to use a channel 9 configuration, the calculated distance between 0.45 times its wavelength can be determined using the formula (299792458 / 7987.2 * 10^6) * 100 * 10 * 0.45, which gives a value of 16.89035mm. Could someone please verify that my new calculation is accurate?
thanks for asking this question.
Have you success to use antenna distance under channel 9, 16.75mm?
Should I change the following variable or any other variables in the code accordingly if change the channel from 9 to 5 and use customer designed antenna distance?
