It always is difficult to build or design one network that does everything equally well. So it is with the latest advances in the 3GPP “Release 13” for Long Term Evolution-Advanced (LTE-A), which includes mechanisms for much-higher and much-lower bandwidth modes. The former for people using smartphones and other devices; the latter for machines communicating with servers.
Release 13 specifies bonding of up to 32 radio carriers, with bandwidth up to 640 MHz, as well as machine-to-machine communications requiring as little as 1.3 MHz of bandwidth, with 600 kHz under study. The narrowband mode supports transmission speeds ranging from 70 kbps to 240 kbps.
