3GPP版本14定义了两个新的低功率广域（LPWA）网络标准，LTE Cat M1和LTE Cat NB1（NB-IOT）。
NB-IOT is one of the new cellular standards targeted to support sensor type and cellular connection applications which need to operate under battery power for ten years or more.
Available Products: NB-IOT（LTE Cat NB1）收发器
NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and enabling a large number of connected devices. The NB-IoT technology can be deployed “in-band” in spectrum allocated to Long Term Evolution (LTE)—utilizing resource blocks within a normal LTE carrier, or in the unused resource blocks within an LTE carrier’s guard-band—or “standalone” for deployments in the dedicated spectrum. It is also suitable for the re-farming of GSM spectrum.
