Webof the spectrum at low power —is more efﬁcient. The concept is counterintuitive: instead of carving a pie into a ﬁnite number of small slices, the technology allows a larger sharing of the whole pie by permitting an all but un-limited number of individuals to take barely noticeable bites. Although spread-spectrum radios use more bandwidth ... WebSpread-Spectrum techniques are methods by which a signal (e.g. an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth.
