NB-IoT Internet of Things has four major characteristics:
1. Wide coverage: Provide improved indoor coverage. In the same
frequency band, NB-IoT has a gain of 20dB over the existing
network, which is equivalent to an increase
100 times the coverage area capacity;
2. Ability to support massive connections: One sector of NB-IoT can
support 100,000 connections, and supports low latency sensitivity
and ultra-low
Equipment cost, low equipment power consumption and optimized
network architecture;
3. Lower power consumption: the standby time of the NB-IoT terminal
module can be as long as 10 years;
4. Lower module cost: The company expects that a single connected
module does not exceed $5.
NB-IOT focuses on the Low Power Consumption Wide Coverage (LPWA)
Internet of Things (IOT) market, and is an emerging market that can
be widely used worldwide
technology. It has the characteristics of wide coverage, multiple
connections, low speed, low cost, low power consumption, and
excellent architecture. NB-IOT uses the license frequency band,
Three deployment methods, in-band, guard-band or independent
carrier, can be adopted to coexist with existing networks.
There are three ways to install remote water meters:
1. Wired connection method:
This connection method requires the installation of water meter
wiring. It can also be wired in the duct well of a newly built
building, or the water meter can be wired outdoors; but it is not
very suitable for wiring in the user’s home. It needs to penetrate
the wall to make holes and destroy the decoration of the user’s
home. Laborious. Routine maintenance is also very troublesome.
There are transmission line problems, power failure of collection
equipment, low meter reading rate and difficult maintenance.
2. The wireless way of using acquisition equipment:
This connection method requires the use of collection equipment,
and the user must deploy and maintain the collection equipment. The
water meter communicates with the collection equipment by wireless
means, and the user must install and maintain the collection
equipment. It is often necessary to maintain the collection
equipment and optimize the blind spots of the network, which
requires quite high technology to maintain.
3. NB Internet of Things:
The NB Internet of Things method does not need to install
collection equipment by yourself, and directly uses the NB base
station network of the telecom operator. It is possible to omit the
original very complicated wiring or equipment erection of remote
water meters, and install and use NB IoT water meters directly like
mechanical water meters in the past.
It can greatly reduce the difficulty of maintaining smart water
meters by the water company and reduce the corresponding labor
costs, which is conducive to the large-scale promotion of NB IoT
water meters.
