Other Parts Discussed in Thread: CC1190, CC1120
I am writing because for a school research project i need to choose a communication system and validate them for our application. My problem is that the communication must work for the downlink from a capsule that can reach speed Mach 3 and it can reach at same time a altitude of about 100km. After some search on internet about LoRa technology we ave founded the TI video where the CC1120 + CC1190 was communicating with more of 100km LoS and we thought these modules can be good for our experiment. At this point we have realized that we don't have found any information about the maximal speed that can be reached from the tx module to avoid that the frequency change induced from the doppler effect have some non negligible effect on the communication (lost of communication).
My question at this point is how sensitive are the CC1120 + CC1190 modules to doppler effect? anybody know the maximal frequency change tolerated on the receiver?
