One of WAVIoT's significant projects in 2019 was the supply of more than 140,000 electricity meters for four projects in regional distribution grid companies that are part of Public Joint Stock Company Rosseti. Rosseti PJSC is an operator of power grids in Russia, one of the largest grid companies in the world.

In 2018-2019, 56 thousand in the Vladimir region (VladimirEnergo distribution company), 34 thousand WAVIoT electricity meters with built-in NB-Fi modems were installed in the Tver region (TverEnergo distribution company), 27 thousand in the Orel region (OrelEnergo distribution company) and 23 thousand in the Lipetsk region (LipetskEnergo distribution company). This project is the largest deployment of IoT based Smart meters in Russia.

Smart grid enables efficient and effective energy management and control, reduces the cost of production, saves energy, and is more reliable than the conventional grid. Smart electricity meters also help energy companies to effectively detect and prevent electric power theft, as well as identify loss sources, which improves the reliability of energy supplying.

With NB-Fi communication technology, WAVIoT Smart electricity meter collects the data from the consumer and sends it to NB-Fi base stations through an NB-Fi radio. Afterward, the data is delivered to the distribution grid companies.

As advanced energy meters, WAVIoT single-phase and three-phase Smart electricity meters can measure energy in two directions: consumption (how much energy the customer consumes from the grid), and generation (how much excess energy the customer exports back to the grid). WAVIoT Smart electricity meters allow controlling them by sending the commands for bulk switch-off of the meters’ load relays and bulk setting of the tariff schedule.

WAVIoT electricity meters measure the following parameters:

The online Meter Data Management system can then provide real-time monitoring of household electricity consumption, solar production and the amount of excess solar power being exported to the grid.

WAVIoT electricity meters were installed everywhere in the regions, even in those spaces where the GSM network coverage was absent. The actual average distance between WAVIoT electricity meters and base stations on these projects was 3 km in urban areas and 7 km in rural areas. Almost all NB-Fi base stations in rural areas were installed on poles, as there were no higher places nearby.

In these four projects, along with electricity meters in standard cases, WAVIoT also supplied meters for outdoor installation (on power utility poles). Such electricity meters can be supplied with remote displays that, besides using the WAVIoT MDM system, allow customers to get the data from the meter via short-range connectivity (“Split system” – the meters and displays are separated).

IoT Solutions

Wireless solutions by WAVIoT are based on the NB-Fi technology that supports secure bidirectional communication for the Internet of Things (IoT), machine-to-machine (M2M), Smart Grid, Smart Utilities, Smart City and industrial applications.

WAVIoT base stations and NB-Fi Transceivers with best-in-class receiver sensitivity enable the use of all advantages of the NB-Fi technology at the same time: long range of bidirectional data transmission, low power consumption and high scalability and stability of IoT networks.

NB-Fi base stations and devices allow fast deployment of IoT applications and provide the protection of confidentiality and integrity of transmitted data by strong encryption algorithms.
