NB-IoT stands for NarrowBand IoT (NB-IoT). This is a particularly energy-efficient wireless standard that is specifically designed for the Internet of Things (IoT).
NB-IoT, a wireless standard based on existing mobile networks, networks end devices in the Internet of Things (IoT). This wireless technology is particularly suitable for IoT projects that occasionally need to transmit small amounts of data and for which low energy consumption is important.
NB-IoT is a low power wide area (LPWA) technology that impresses with its low energy requirements and high building penetration. This means that a reliable connection is also possible in underground basements, garages or other buildings with many obstacles.
LPWA networks, such as NB-IoT, are optimal for IoT applications where energy consumption, building penetration, battery life and costs are critical. In addition to NB-IoT, LTE-M is also used as a mobile technology for such use cases.
Many IoT devices only send small amounts of data sporadically. In these cases, NB-IoT proves to be ideal. The simple radio modules, which are limited to essential functions, make the network standard cost-effective and energy-saving. This makes NB-IoT a pioneer of IoT in many areas where networking was previously too expensive and complex.
Both NB-IoT and LTE-M chipsets focus on radio characteristics and power saving features (e.g. sleep mode, Long-Periodic Tracking Area Updates and Extended Discontinuous Reception), ensuring optimal energy efficiency.
NB-IoT as well as LTE-M convince with low operating and service prices as well as favourable module costs. This is made possible by the chipset design, in which unneeded LTE functions have been dispensed with, and the overall increase in production volumes.
Compared to GSM, NB-IoT and LTE-M have up to 20 decibels (NB-IoT) and 15 decibels (LTE-M) higher power density. This is achieved via narrowband modulation methods and multiple transmission repetitions.
NB-IoT as well as LTE-M work very simply via Plug & Play. Without installing local networks or gateways, sensors can be connected directly to the NB-IoT and/or LTE-M network.
NB-IoT and LTE-M are globally standardised technologies. Both networks use LTE security mechanisms according to 3GPP, and security functions are constantly being reviewed and improved.
NB-IoT and LTE-M are both based on LTE technology and can therefore be easily integrated into existing LTE infrastructures via software upgrade.
