1/2inch~1inch Body Brass Nb Iot Remote Reading Smart Water Meter

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.
