Narrow band includes a modulation technique in which a signal is transmitted as a radio frequency (RF) signal at or within a frequency band. Spread spectrum includes a modulation technique in which a signal is transmitted as an RF signal spread over a range of frequencies.

What is narrow band spectrum?
In the audio spectrum, narrowband sounds are sounds that occupy a narrow range of frequencies. In telephony, narrowband is usually considered to cover frequencies 300–3400 Hz, i.e. the voiceband.
What are the advantages of spread spectrum system over narrow band spectrum system?
The main advantage of spread spectrum communication technique is to prevent “interference” whether it is intentional or unintentional. The signals modulated with these techniques are hard to interfere and cannot be jammed. An intruder with no official access is never allowed to crack them.
What are the 3 varieties of spread spectrum?
Frequency-hopping spread spectrum (FHSS), direct-sequence spread spectrum (DSSS), time-hopping spread spectrum (THSS), chirp spread spectrum (CSS), and combinations of these techniques are forms of spread spectrum.
What is difference between wideband and narrowband?
Narrowband systems typically have lower data rate transmissions, whereas wideband systems support relatively higher data rate transmissions. To put simply, wideband systems allow for faster communication.
