Abstract :
The authors describe a scenario in which a direct-sequence spread-spectrum personal communications network is overlaid on top of an existing set of narrowband microwave users. An overlay of this type results in very efficient use of the RF spectrum, and is indicative of what needs to be done to relieve the spectral congestion at radio frequencies
