In 2018-2019, the four Smart Grid projects were installed the 56, 34, 27 and 23 thousand of WAVIoT electricity meters with built-in NB-Fi modules respectively. These projects are the largest deployments of IoT based Smart meters in the country. 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.
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).
