LTE-M or LTE-MTC ("
Long-Term Evolution Machine Type Communication"), is a type of
low-power wide-area network
A low-power wide-area network (LPWAN or LPWA network) is a type of wireless telecommunication wide area network designed to allow long-range communications at a low bit rate among things (connected objects), such as sensors operated on a batter ...

), in June 2016.
Competing 3GPP IoT technologies include
NB-IoT and
EC-GSM-IoT.
The advantage of LTE-M over NB-IoT is its comparatively higher data rate, mobility, and
voice over the network, but it requires more bandwidth, is more costly, and cannot be put into
guard band
In radio, a guard band is an unused part of the radio spectrum between radio bands, for the purpose of preventing interference.
It is a narrow frequency range used to separate two wider frequency ranges to ensure that both can transmit simultane ...

frequency band
A frequency band is an interval in the frequency domain, delimited by a lower frequency and an upper frequency. The term may refer to a radio band or an interval of some other spectrum.
The frequency range of a system is the range over which i ...
for now. Compared to LTE Release 12 Cat-0 modem, an LTE-M model is claimed to be 80% less expensive (in terms of the bill of materials), support up to 18 dB better coverage, and a battery lifetime that can last up to several years.
