M2M Challenges and Opportunities in 4G

4G technology includes a profile for M2M communications in order to improve the efficiency of the foreseeable connection of hundreds of devices to the broadband wireless networks. These devices impose different requirements to those of human communications, most significantly their bursty nature and the small payload usually associated with each transmission. Due to this, typical signalling procedures overload the network causing a very low efficiency for these communications. This paper is a review of current literature, commenting on challenges that LTE technology must overcome to be a true opportunity for M2M devices.
