4 FAQs about Nb-iot base station power supply

What is NB-IoT power supply?

This reference design provides a power supply solution for NB-IoT (Narrow Band-Internet of Things) in smart meters with LiSOCl2 Batteries applications. The design is a low standby current, high efficiency solution that extends battery use time more than 50%.

What is NB-IoT designed for?

Narrowband internet of things (NB-IoT) is a recent cellular radio access technology based on Long-Term Evolution (LTE) introduced by Third-Generation Partnership Project (3GPP) for Low-Power Wide-Area Networks (LPWAN).

What is the power consumption of NB-IoT?

In [79], the authors presented the NB-IoT power measurement. NB-IoT transmission consumes 716 mW when at 23 dBm with a power efficiency of 37%. DL control and data signals consume 213 mW, idle-mode-eDRx and PSM consume 21 mW and 13 μW, respectively.

Does NB-IoT support different power classes?

NB-IoT devices might support different power classes such as 14 dBm, 20 dBm, or 23 dBm. However, they are configured to use the minimum allowed transmit power to avoid co-channel interference with other UEs.
