NB - IOT WATER METER
NB IOT advantages: authorized frequency band, high security; Compared with LTE, the gain is increased by 20dB, the transmission power is increased by 100 times, and the coverage is 10km +; Super long DRX (discontinuous receiving) power saving technology and PSM power saving mode, 10 years battery life; Big connection, 50000 connections. NB IOT intelligent water meter on-line success rate of more than 99%.
"In the past, users' water consumption was collected according to the scale, while NB IOT smart water meter can realize electronic measurement, convert the scale into electronic degree, and realize the real-time transmission of users' water consumption to the water intelligent management platform through the electronic chip installed in the box.
In the past, GPRS was used as the communication means for water meters to send data. A base station can only load hundreds of water meters at the same time. After using the narrow-band Internet of things technology, a base station can concurrent 50000 water meter data at the same time, and the data is no longer processed twice, avoiding the potential risk of misreading. At the same time, Nb IOT smart water meter's "small appetite" (low power consumption) is only one tenth of the traditional GPRS water meter.
