The NB-IoT

The NB-IoT (NarrowBand Internet of Things) is a cellular communication standard for devices with a small amount of data.

Сommunication standard

The existing mobile operators’ infrastructure is used for the NB-IoT communication standard. The network is deployed inside the main LTE baseband or outside the baseband between neighbouring LTE carriers.

Thus, the functions available in LTE are used in NB-IoT. The NB-IoT services are provided by mobile operators along with other services: voice mobile communication, high-speed LTE data transmission, etc.

Advantages:

The NB-IoT is an open world standard, all equipment is compatible, the devices operation does not depend on the operator and the region of use
The NB-IoT standard is initially targeted at the B2B/M2M market, so it takes into account many features of the target market
The technology is in demand and is actively developing and improving
The coverage area of the main operators includes million-plus cities
High-quality signal penetration owing to the use of low-frequency bands
The sufficiently high speed of data exchange, allowing to build full-fledged AMR/AMI systems
The large network capacity per base station, excellent network scalability and long range
The optimal solution for devices with the proactive data transmission and traffic limitation capability
The minimal traffic with the software limitation possibility and automatic schedule settings for traffic: less than 1 MB per year, depending on the settings
The capability to build systems with a master-meter which polls several other meters via the RS-485 interface and to save traffic, as well as to reduce the cost of the system as a whole

Features:

High data transfer rate in comparison with other LPWAN networks
The capability to use mobile operators’ cloud platforms for data collection
The prospect of switching from classic SIM cards to programmable eSIMs
Moderate subscription fee

Other technologies

G3-PLC

Technologies provide data transmission by power supply lines. There are several different PLC technologies: for data transmission over high-voltage power lines, telemetry data transmission and broadband data transmission over low-voltage networks. The technology is also an international open standard focused on global application. The mesh network topology is used. The data transfer speed is not high, to 35 kbps (CENELEC)/128 kbps (ARIB).

GSM

An international standard of digital cellular communication based on which it is possible to deploy AMR/AMI in the existing mobile operators networks without creating own infrastructure, which is the main advantage of such systems.

LoRaWAN

A highly reliable standard for wireless low-power private networks in the unlicensed 868 MHz band. It allows transmitting small amounts of data at a distance of up to 15 km in the line of sight and 1.5 – 2 km in densely built-up urban areas.

DLMS/COSEM

DLMS/COSEM (Device Language Message Specification/Companion Specification for Energy Metering) represent an important standard for communication between smart energy meters and control systems. This standard provides a data structure and format that facilitates the exchange of energy consumption information and data.
