Access Channel Enhancements for 1x Rel. F One Eighth Rate Access Probes for Smart Terminals Evolve Random Access Channels for IoT: I Introduction Evolve Random Access Channels for IoT: III Slotted ALOHA Models During the discussion of evolving access channels for machine-to-machine (M2M) communication liked services, two major requirements are defined. As stated by 3GPP2 system requirement document, one is "[a]n M2M service shall not impact any ... existing applications and services that are currently being supported". The other one is "[t]he scalability of M2M Device deployment shall be supported ...to allow flexible M2M Device and service deployment scenarios for large numbers of M2M Devices." More details of these two requirements can be found in 3GPP2 Machine-to-Machine Communication System Requirements, S.R0146-0 and 3GPP M2M Service Requirements, ETSI TS 102-689 . Due to the nature of M2M traffic pattern and QoS requirement, recent studies find ou
