The spreading factor defines the relation between symbol rate and chip rate. A higher spreading factor increases sensitivity and range, but also prolongs the airtime of a packet and will likely raise the risk of a collision.

What is spreading factor in spread spectrum?
The ratio between the bandwidth of the user signal and the transmit bandwidth is called the "spreading factor".
Which enzyme acts as spreading factor?
Hyaluronidase in snake and insect venom is thought to function as a “spreading factor” by degrading host hyaluronic acid, thus allowing spread of toxin (13).
What is spreading code in Wcdma?
THE SPREADING PROCESS
WCDMA uses Direct Sequence spreading, where spreading process is done by directly combining the baseband information to high chip rate binary code. The Spreading Factor is the ratio of the chips (UMTS = 3.84Mchips/s) to baseband information rate. Spreading factors vary from 4 to 512 in FDD UMTS.
What is chirps in LoRa?
LoRa® is a spread spectrum modulation technique based on the Compressed High-Intensity Radar Pulse or "chirp" spread spectrum and is a physical layer in LoRaWAN. It uses so-called "chirps"; that is, a signal with frequency moving up or down (up-chirp or down-chirp respectively) with a different speed.
What is LoRa coding rate?
The coding rate refers to the proportion of transmitted bits that actually carry information. Coding rate can be 6/8, 4/8, etc… So if CR is 4/8 we are transmitting twice as many bits as the ones containing information.
