NB-loT refers to Narrow Band-Internet of Things technology. Focusing on the Low Power Wide Coverage (LPWA) Interet ofThings loT) market, NB-OT is an emerging technology that can be widely used around the world. NB-1OT uses the licensefrequency band, and can be deployed in three ways: in-band, guard band, or independent carer to coexist with the existingnetwork.

Centralized meter reading mode Fixed Network Long Range By GPRS/CDMA/3G/4G
Technical Details
In buildings and plazas, normally the density of residence are very high. lt is very suitable to useLoRa to give coverage.
It will make the civil work much more easier thus save the cost on service part, and save thecost for accessories.
The concentrator will read the data from the water meters and upload the data to the softwareplatform.
Our LoRa concentrator can manage 1000 water meters at most.

Technical Details
In Medium density, LoRa is still a good technology to give coverage, provide walk by and drive by options.
For medium density scenario, is not easy to nd in door environment to install the concentrator, we will provide pole mounted out door cabinet.
In this scenario, the water meters will have in door installation and out door installation. For out door installation, an out door meter box will be needed.
The concentrator will read the data from the water meters and upload the data to the software platform.
When water meter is installed in complex environments, such as locations with poor signal coverage (e.g., inside multiply walls or pitted underground) or where the distance from the concentrator is too far, it can act as a relay (optional) to transmit data to the nearest other water meter, with multi-level transmission until the data reaches the concentrator.
Technical Details
Low density community normally locates in the mountain area and countryside. provide walk by and drive by options.
Considering the cost of the LoRa solution, it is recommended to install 2G/3G/4G modules in the water meter
This system is a smart water management platform, which integrates remote meter reading system, revenue system, water pipe network monitoring system, reporting system, alarm system and work order system.
It will not only deal with a comprehensive work from the return data of the network monitoring devices , but also capable of powerful data analysis, data mining, water supply planning for the Water Utilities.
