LTE vs NB-LTE | Difference between LTE and NB-LTE or NB-IoT


This page compares LTE vs NB-LTE and describes difference between LTE and NB-LTE (i.e. NB-IoT) technologies.


Specifications LTE NB-LTE or LTE-NB or NB-IoT
Specification 3GPP Release 8/9 (Basic LTE),
3GPP Release 10 (Advanced LTE)
3GPP Release 13 .. (Cat-NB1)
3GPP Release 14 .. (Cat-NB2)
Abbreviation Long Term Evolution, General term for all 4G LTE Narrow Band LTE
Device cost Costlier Cheaper, 5 to 10 $ per module, 10% less compare to LTE-M
Bandwidth Supports various ranges of BW ( i.e. 1.4MHz, 3.0MHz, 5MHz, 10MHz, 15MHz, 20MHz) Narrower BW (180 KHz)
Latency Higher than LTE-M , about 1.5 to 10 sec Lower, about 50 to 100ms
Battery Life Short Long, +10 Years, depends on use case
Maximum Data rate 300 Mbps Downlink(DL) with 4x4 MIMO and 20 MHz configurations , 75 Mbps Uplink (UL) < 100 Kbps (i.e. 30Kbps or 60Kbps)
Service costs or deployment costs Higher Lower
Coverage About 2 to 10 miles 7 times of LTE
