About the NB-Fi Standard

The National Standard for the Internet of Things NB-Fi (Narrow Band Fidelity) "Wireless Data Transmission Protocol Based on Narrow-Band Radio Signal Modulation (NB-Fi)" was developed by the technical committee "Cyber-Physical Systems" based on RVC on the initiative of the Internet of Things Association.

The standard is included in the line of LPWAN protocols, which regulate the transmission of small-scale data over long distances, and is simple and cheap, noted in the RVC.

2022: Rosstandart approved GOST for data transfer protocol on the Internet of Things

In mid-March 2022, the Federal Agency for Technical Regulation and Metrology (Rosstandart) approved a national GOST for a data transfer protocol using the Internet of Things (NB-Fi). According to the press service of the department, the first IoT standard in Russia, which received the status of a full-fledged GOST R after a three-year test.

The document was developed by experts of the Technical Committee 194 "Cyber-Physical Systems" with the participation of the Association of the Internet of Things and Telematic Solutions. The standard is based on Russian technology, which allows you to create wireless data exchange networks between many devices and many base stations. An example of using the NB-Fi protocol in practice can be intelligent energy metering systems with the ability to remotely collect readings and control metering devices.

Rosstandart after a three-year test and revision gave the status of a national GOST to a preliminary standard in the field of data transmission in Internet of Things networks

It is noted that the use of NB-Fi technology in devices allows ensuring a stable data transmission range of up to 10 km in conditions of dense urban development and up to 30 km in rural areas.

According to Andrei Bakumenko, co-founder and deputy general director of Telematic Solutions LLC, the NB-Fi standard has given a powerful impetus to the spread of NB-Fi technology in other sectors of the economy, except for traditional energy and housing and communal services. Developed innovative solutions for wireless data transfer allow companies to implement their strategy to improve the safety, reliability and energy efficiency of production processes, he said.

The NB-Fi standard is unique to us in its own way - it has passed all stages of development in our circuit and is a reference example of the legitimization of Russian technologies. Taking into account the path traveled, we can guarantee the quality of the standard and standardized technology as GOST R - and its unhindered practical use, "added Nikita Utkin, Director for the Development of Technological Standards at the NTI Platform, Chairman of the Technical Committee for Standardization No. 194" Cyber-Physical Systems "(TC 194).

2020: Developed by GOST for IoT protocol NB-Fi

December 28, 2020 it became known about the development in Russia of the national standard GOST R "Information Technologies. Internet of Things. Narrowband Radio Modulation (NB-Fi) based wireless data protocol. " The document was created as part of the 194 Cyber-Physical Systems technical committee on the basis of RVC with the participation of Telematic Solutions LLC and the Internet of Things Association.

GOST is developed on the basis of the preliminary national standard of the same name PNST NB-Fi, which was approved by Rosstandart. It is noted that during his testing, the issues of security and power of attorney of the protocol were studied in detail, refinements were carried out in accordance with the progress in the development of both the NB-Fi protocol itself and the Internet of Things technology itself.

GOST for Internet of things protocol NB-Fi is presented in the Russian Federation

According to the RVC, the Russian technology of wireless data transmission (NB-Fi) allows you to create wireless networks for the exchange of information between many devices and base stations. Such technologies are necessary for the development of the Internet of Things, which involves the transfer of a large amount of data, including over long distances. Networks for which a new national standard has been developed will provide signal transmission up to 10 km in urban conditions, where building density can create barriers to communication quality, and in rural areas, devices will be able to exchange data at a distance of up to 30 km.

The NB-Fi standard gave a powerful impetus to the spread of NB-Fi technology in sectors other than traditional energy and housing and communal services. In particular, an NB-Fi device developed by a third-party company has already appeared for use in the oil and gas industry. The standard helps and works, "said Andrei Bakumenko, deputy general director of Telematic Solutions LLC.[2]

2019: Approval of the preliminary national standard of the Internet of Things NB-Fi

The Federal Agency for Technical Regulation and Metrology (Rosstandart), on the proposal of the 194 Cyber-Physical Systems Technical Committee, created on the basis of RVC, approved the preliminary national standard "Protocol for wireless data transmission based on narrow-band modulation of the radio signal (NB-Fi)." The document will be put into effect from April 2019, TAdviser was informed on February 5, 2019 in the RVC.

The use of NB-Fi technology in devices allows you to ensure a stable data transmission range of up to 10 km in conditions of dense urban development and up to 30 km in rural areas. At the same time, the production of final devices requires an affordable component base with a high degree of localization of production, according to the company.

As of February, a Russia corresponding transceiver has already been developed in the form of an integrated circuit transmitting data using the NB-Fi protocol. The NB-Fi transceiver can be used in different countries, operating in unlicensed frequency bands of 430-500 MHz and 860-925 MHz and transmitting data at speeds in the air from 50 to 25,600 bps. In addition, the NB-Fi chip allows you to achieve high sensitivity of signal reception without using complex antenna equipment, while maintaining ultra-low power consumption.

According to experts, the implementation of the standard will unify the principles of information exchange in the Internet of Things market and create an ecosystem of device manufacturers.

Promising areas of use of the NB-Fi standard - housing and communal services, electric power, logistics, transport, as well as industrial IoT solutions. The application of uniform standards by manufacturers in IoT solutions will allow the introduction of complex projects in various areas thanks to a large product line of compatible Internet of Things devices, "said Andrei Kolesnikov, director of the Internet of Things Association.

The Cyber-Physical Systems Technical Committee, together with market players, made a local breakthrough by proposing one of the promising standards of the Internet of Things. It is also important that the current format of the Preliminary National Standard was chosen for him, which allows for wider testing and adjustment before its transfer to GOST status, "said Anton Shalaev, deputy head of Rosstandart.

Over the next three years, Cyber-Physical Systems TC will systematically monitor and evaluate the application of the approved preliminary standard, which will allow gaining the necessary practical experience in its market application before being transferred to GOST status.

First of all, the monitoring will include cases of the application of the standard by members of the Internet of Things Association, which initiated the development of the standard. As of February 2019, the standard is already being actively used in practice by market players, in particular, WAVIoT, which is developing electricity and water meters with a wireless data transfer function and introducing solutions for automating the collection of readings of housing and communal services meters.

When developing the national NB-Fi standard, we took into account a wide range of opinions of the expert and technological community. Public discussion of the draft document took place within three months, conclusions were received from key market participants. At the same time, NB-Fi is not the only promising communication standard for the Internet of Things. There is room in the market for at least a few standards that can find serious support for their development by formalizing as national standards. The further success of each of them will depend on a combination of factors: adaptability and consideration of the nuances of specific markets, equipment requirements, types of end devices, the cost of their implementation and use, the completeness of coverage by the communication network, the cost of base stations, "said Nikita Utkin, chairman of Kiber-Physical Systems.

TC "Cyber-Physical Systems" and Rosstandart collect information on the practical application of the NB-Fi standard. These information, as well as comments and proposals on the content of the standard can be sent no later than 4 months before the expiration of its validity to the TC "Cyber-Physical Systems."

2018

International standards for the Internet of Things will be developed in Russia

Draft first national standard for the Internet of Things

In April 2018, the RVC submitted a draft of the first national standard for the Internet of Things. The document was developed as part of the Technical Committee 194 "Technical Committee of Cyber-Physical Systems (TC 194)" on the basis of the RVC with the participation of the FRIA, the Association of Participants in the Internet of Things Market and Telematic Solutions LLC.

The standard is based on completely Russian technology, harmonized with international analogues, which allows you to create wireless data exchange networks between many modems on one side and many base stations on the other side.

The standard is part of the line of LPWAN protocols that regulate the transmission of small-scale data over long distances. The object of standardization is the requirements for the exchange protocol for the "Internet of Things" in the narrowband spectrum (NB-Fi). The standard involves the use of Ultra Narrow Band (UNB) phase-manipulated signals, which, in combination with noise-resistant coding, allow you to achieve very high values ​ ​ of reception sensitivity (up to -150 dBm).

The deployment of the network and the start of data transmission from devices do not require the creation of a complex architecture, and the maximum number of metering points that a single base station can simultaneously serve is practically unlimited. At the same time, the radius of data transmission to the base station is up to 50 km, and the autonomous operation of devices without recharging reaches 10 years. After the adoption of the standard, companies in the Internet of Things market will be able to use existing base stations for free, as well as order the production of meters according to unified requirements from any manufacturer.

We expect that the standard will play an important role in the development of various means of managing cyber-physical objects due to its simplicity and cheapness. The high energy efficiency of the standard allows you to use unlicensed frequency ranges for operation, in which restrictions are set on the power emitted by transmitters. One of the most promising markets for the use of such a standard is the housing and communal services sector, in particular the market for wireless systems for controlling and accounting for public resources. It is also important to note that the standard can be implemented on a component basis with a high degree of localization in Russia, "said Nikita Utkin, chairman of the 194 Cyber-Physical Systems Technical Committee.

The draft standard is presented for public discussion, which will last for three months. The corresponding notification is posted on the site gost.ru. After that, the draft standard will be submitted for approval by the Technical Committee 194 Cyber-Physical Systems and submitted to Rosstandart for approval. The adoption of the standard is expected no later than the beginning of 2019.
