NB-IoT technology is known for its ultra-low power consumption, making it ideal for long-term deployment in remote or hard-to-reach locations. The module operates on a very low current, typically in the milliampere (mA) range during communication and microampere (µA) during standby. This remarkable efficiency allows the device to remain active for up to ten years without requiring battery replacement, significantly reducing maintenance costs and efforts in the long run, especially for applications like manhole cover monitoring.
Another key advantage of NB-IoT is its strong and wide signal coverage, which can penetrate deep indoors and even reach underground areas. This makes it highly suitable for monitoring systems that require reliable connectivity in challenging environments, such as manhole covers located beneath roads or in basements.
Compared to older technologies like GPRS, NB-IoT overcomes several limitations, including poor indoor coverage and high power consumption. With its ability to support a large number of connected devices and maintain stable communication, NB-IoT is set to play a crucial role in the future of wireless communication, particularly in smart city and industrial IoT applications.
