Enhancements to CDMA2000 1x for M2M communications

Machine-to-machine (M2M) communications has recently become a growth area for wireless technologies. In this paper, we analyze the advantages of using CDMA2000 1x technologies for M2M communications and present a set of enhancements to its air interface that have been standardized in 3GPP2 (Rev F). Through simulation studies on real-world applications, we show that these enhancements can achieve significant improvements in device battery life and network capacity.
