Comparison between DSSS and FHSS

Since FHSS systems rely on different RF carrier frequencies, error bursts are mainly due to frequency selective fading.
Error Rate: In DSSS, the information bits are distributed over frequency and time planes, thus minimizing the effects of interference and fading. Therefore, DSSS systems are prone to errors, but at a lower level compared to FHSS systems. FHSS produces strong burst errors.
Although both techniques have errors, it can be seen that the error rate is higher in FHSS than in DSSS systems. Whenever any device approaches the blocking frequency as it hops between channels, the bandwidth of the FHSS system drops.
Compared with DSSS, the decoding process of FHSS is easier. Specific algorithms are required in DSSS to establish the connection between sender and receiver https://www.cdebyte.com/Module-Lora
Network capacity: The transmission rate of DSSS is higher than that of FHSS, DSSS provides a capacity of up to 22 Mbps, while FHSS supports a capacity of up to 3 Mbps.
Reliability: DSSS is more reliable than FHSS systems, which are less reliable in applications. But for mobile applications FHSS is more energy efficient.
Acquisition Time: The time required to convert an analog signal to a digital signal, more in DSSS systems than in FHSS systems.
Cost of use: DSSS is more expensive than FHSS. At lower Mbps (like 2 Mbps), FHSS is less expensive, but generally, radio signals are used at higher Mbps, and DSSS will be cheaper than FHSS.
Application scenarios: In harsh environments, including the presence of large coverage, noise, multipath, and Bluetooth frequency waves, etc., DSSS is ideal for point-to-point applications, while FHSS can be used for point-to-multipoint deployments with excellent performance.
