NB-IoT water meter uses NB-IoT technology to achieve remote monitoring and management of smart water meters. Its characteristics of low power consumption, wide coverage and low cost make the water meter data can be transmitted to the cloud in real time to achieve remote meter reading, anomaly monitoring and other functions, providing an efficient and convenient solution for water management.
Brief introduction
The NB-loT system consists of the NB-loT management system platform, base stations, and loT water meters (NB-loT). The system has a high degree of automation, can monitor the operation and consumption of the meter at any time, and has a wide range of applications.
Technical Features
1. High security
•Two-way authentication;
•The air interface is strictly encrypted;
•Dedicated channel, no other signal interference,and more stable data transmission
2.Wide coverage
•20db gain, coding gain;
•lmproved narrowband power spectrum density;
•lt has a retransmission mechanism when automatic transmission fails;
•China Mobile/Telecom's NB-loT base station has achieved full coverage
3.Low power consumption
•Battery life of more than 6 years (1 day/1 communication);
•Simplify protocol and chip micro power consumption;
•High functional efficiency;
•Short transmission/reception time;
4.Big connection
•High frequency increase efficiency;
•Small packet data sending characteristics;
•Very low activation ratio of the terminal.
5. Product implementation standards
•ISO9001; GB/T778.1.2.3-2007;JJG 162-2009;CJ/T 188-2004.
