Narrowband Internet of Things (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard developed by 3GPP to enable a wide range of cellular devices and services.[1][2] The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016.[3] Other 3GPP IoT technologies include eMTC (enhanced Machine-Type Communication) and EC-GSM-IoT.[4]
Code: 124-315, 124-317; Description: Speed mismatch or Product Model. Code: 124-326; Description: IOT Speed Not Registered At boot, the status of speed.
NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications. [5][6][7][8][9]
In March 2019, the Global Mobile Suppliers Association announced that over 100 operators have deployed/launched either NB-IoT or LTE-M networks.[10]. This number had risen to 142 deployed/launched networks by September 2019.[11]

Deployments[edit]
As of March 2019 GSA had identified:[14]
- 149 operators in 69 countries investing in one or both of the NB-IoT and LTE-M network technologies
- 104 of those operators in 53 countries had deployed/launched at least one of the NB-IoT or LTE-M technologies of those, 20 operators in 19 countries had deployed/launched both NB-IoT and LTE-M[15]
- 22 countries are now home to deployed/launched NB-IoT and LTE-M networks
- 29 countries are home to deployed/launched NB-IoT networks only
- Two countries are home to deployed/launched LTE-M networks only
- 141 operators in 69 countries investing in NB-IoT networks; 90 of those operators in 51 countries had deployed/launched their networks[15]
- 60 operators in 35 countries investing in LTE-M networks; 34 of those operators in 24 countries had deployed/launched their networks
Devices and modules[edit]
The 3GPP-compliant LPWA device ecosystem continues to grow. In April 2019, GSA identified 210 devices supporting either Cat-NB1/NB-2 or Cat-M1 – more than double the number in its GAMBoD database at the end of March 2018.[16] This figure had risen a further 50% by September 2019, with a total of 303 devices identified as supporting either Cat-M1, Cat-NB1 (NB-IoT) or Cat-NB2. Of these, 230 devices support Cat-NB1 (including known variants) and 198 devices support Cat-M1 (including known variants). The split of devices (as of September 2019) was 60.4% modules, 25.4% asset trackers, and 5.6% routers, with data loggers, femtocells, smart-home devices, and smart watches, USB modems, and vehicle on-board units (OBUs), making up the balance.[17].
To integrate NB-IoT into a maker board for IoT developments, SODAQ, a Dutch IoT hardware and software engineering company, crowdfunded an NB-IoT shield on Kickstarter[18]. They then went on to partner with module manufacturer u-blox to create maker boards with NB-IoT and LTE-M integrated[19].
