One option to improve the performance of delay-tolerantM2M services is obtained by combining Random Beamforming (RBF) with opportunistic schedul-ing. RBF induces larger channel fluctuations in semi-staticwireless environments, while opportunistic scheduling selects M2M devices when the effective instantaneous channel experiences constructive fading. A novel approach to enable narrowband M2M connectivity is introduced, and a simplified methodolog
