Abstract-The capacity limits of the Random Access Channel (RACH) of Long Term Evolution (LTE) for highly dense Machine-to-Machine communications are studied in this paper. We consider the case study when a high number of devices attempt to transmit information to the same base station in a very short period of time. Simulations have been performed considering several parameter configurations related to the random access procedure of LTE. The energy consumption is used as a primordial metric to compare any improvement regarding the random access procedure in future releases, in order to evaluate the impact on the battery lifetime of autonomous devices.
Finally, energy consumption considerations in LTE random access are studied in REF .
