A wireless communication method between a plurality of end-points by a plurality of base stations, based on frames that have a chirp spread spectrum,CSS,-modulated preamble followed by a data body modulated at a narrower bandwidth, either by CSS or by an ultra-narrowband, UNB modulation. The system facilitates avoidance or mitigation of collision between packets and allows increase in network capacity, while maintaining the simplicity of detection inherent to CSS modulation. |
