Hi,
I am trying to understand the meaning of SF(Spread Factor). Reading the sx1272.pdf I came across to a parameter called chip rate. Here is an example of the .pdf
Spreading factor:
The spread spectrum LoRaTM modulation is performed by representing each bit of payload information by multiple chips of information. The rate at which the spread information is sent is referred to as the symbol rate (Rs), the ratio between the nominal symbol rate and chip rate is the spreading factor and represents the number of symbols sent per bit of information.
So, I ask to help me to understand what is Spread Factor by first explain me what is chip and symbol rate.
Excuse my bad English.
