EC-GSM-IoT Vs NB-IoT Vs LTE Cat-M1 | difference between EC-GSM-IoT NB-IoT LTE Cat-M1
This page compares EC-GSM-IoT Vs NB-IoT Vs LTE Cat-M1 and describes difference between EC-GSM-IoT, NB-IoT and LTE Cat-M1.
Introduction:
All these three 3GPP standards are used for IoT (Internet of Things).
EC-GSM-IoT: Enhancements to existing GSM/EGPRS to support extended coverage,
long life, low device cost, variable rates, higher number of subscribers,
enhanced security etc. Refer EC-GSM IoT basics>>
NB-IoT: It stands for Narrow band-IoT.
It is specified in LTE Release-13. It is successor to LTE Cat-M technology.
It fulfills requirements of Low Power Wide Area Network.
It offers long battery life, lower latency, better coverage compare to LTE-M technology.
Refer NB IoT tutotial >>
LTE Cat-M1: It is LPWA network air interface which allows
to connect with IoT and M2M devices at medium data rates.
It supports about 375 Kbps data rates in downlink and uplink
with half duplex mode. It offers long battery life with extended
coverage.
It is also known as eMTC (enhanced machine-type communication).
It is part of 3GPP Release 13.
