The IoT and 5G massive Machine-Type Communications
(mMTC) will be a large market in 5G. NB-IoT is a Low Power Wide AreaNetwork
(LPWAN) radio technology 4G standard for IoT sensorsand devices to communicate
over cellular networks. However,unlike many other characteristics of 5G, NB-IoT
is not necessarily designed for speed.
Cat-NB1 uses a channel bandwidth of just200kHz, more akin
to the old Global System for Mobile Communications (GSM) standard than the
20MHz of LTE and 100MHz of5G NR.Cat-NB1 and its 5G derivative is the antithesis
of 5G enhanced Mobile Broadband (eMBB). It uses the narrowest bandwidth
andslowest data rate to lower costs and enable a ten-year (or
more) battery life.
Kbps stands for kilobits per second — and one
million kilobits equalsone gigabit — a popular measure of speed back when
modems used tone-modulated phone signals (accompanied by annoyingscreeching
sounds) and people still used the yellow pages.
NB-IoT is designed primarily for IoT sensors and devices.
Thelong range, using bands less than 1GHz, allows a vast network of low power
sensors, each sending small data reports, to be aggregated efficiently. For
these devices, it isn’t critical that the data they transmit is received with
ultra-low latency, or that every transmission be acknowledged by the receiver.
Thus, NB-IoT is an ideal technology for massive IoT use cases
