LTE vs LTE-M | Difference between LTE and LTE-M

This page compares LTE vs LTE-M and describes difference between LTE and LTE-M technologies.


Specifications LTE LTE-M
Specification 3GPP Release 8/9 (Basic LTE),
3GPP Release 10 (Advanced LTE)
3GPP Release 13 .. (Cat-M1)
3GPP Release 14 .. (Cat-M2)
Abbreviation Long Term Evolution, General term for all 4G LTE LTE for Machine Communication (LTE with category M1) , Such IoT devices connect directly with 4G LTE network without gateway
Device cost Costlier Cheaper
Bandwidth Supports various ranges of BW ( i.e. 1.4MHz, 3.0MHz, 5MHz, 10MHz, 15MHz, 20MHz) Narrower BW (about 1.4 MHz)
Battery Life Short Long, due to use of PSM and eDRX modes battery life upto 10 years can be achieved.
Maximum Data rate 300 Mbps Downlink(DL) with 4x4 MIMO and 20 MHz configurations , 75 Mbps Uplink (UL) About 100 Kbps to 360 Kbps
Service costs or deployment costs Higher Lower
Coverage About 2 to 10 miles 4 times of LTE
Number of devices Less than LTE-M Supports massive number of devices
Frequency Bands Bands include 1 to 12, 13 to 25, 33 to 43. Refer LTE Frequency Bands >>. Release 13 provides the list of the supported bands: 1, 2, 3, 4, 5, 7, 8, 11, 12, 13, 18, 19, 20, 26, 27, 28, 31, 39, 41 and Release 14 added the bands viz. 25 and 40.
Module size Not suitable as wearables Suitable as wearables
Duplexing support Support TDD and FDD (both full duplex or half duplex) Half duplex and full duplex for FDD and TDD, however currently supported frequency bands are only operating in FDD. Full duplex operation, which means that the device supports simultaneous transmission and reception, or half-duplex operation, which means that the device alternates between transmission and reception.
