LTE vs NB-LTE: Understanding the Key Differences

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

SpecificationsLTENB-LTE or LTE-NB or NB-IoT
Specification3GPP Release 8/9 (Basic LTE), 3GPP Release 10 (Advanced LTE)3GPP Release 13 .. (Cat-NB1) 3GPP Release 14 .. (Cat-NB2)
AbbreviationLong Term Evolution, General term for all 4G LTENarrow Band LTE
Device costCostlierCheaper, 5 to 10 $ per module, 10% less compared to LTE-M
BandwidthSupports various ranges of BW ( i.e. 1.4MHz, 3.0MHz, 5MHz, 10MHz, 15MHz, 20MHz)Narrower BW (180 KHz)
LatencyHigher than LTE-M , about 1.5 to 10 secLower, about 50 to 100ms
Battery LifeShortLong, +10 Years, depends on use case
Maximum Data rate300 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 costsHigherLower
CoverageAbout 2 to 10 miles7 times of LTE
Voice supportYesNo (only data is supported)
Mobility supportYesLimited
Frequency BandsBands include 1 to 12, 13 to 25, 33 to 43.LTE in-band, LTE guard band and GSM repurposing
Module sizeNot suitable as wearablesSuitable as wearables
Duplex supportBoth half duplex and full duplexHalf duplex
