The NB-IoT has ultra-low power consumption. The normal communication and standby currents are mA and uA. The module standby time can be as long as ten years, which greatly simplifies the maintenance of the manhole cover in the later stage.
NB-IoT has a stronger, wider signal that can be used to cover indoors and basements, enabling true coverage in manhole cover monitoring.
NB-IoT technology breaks through the bottleneck of GPRS technology and will definitely shine in the wireless communication industry in the future.
