For operators, we offer complete construction of networks for internal coverage, in variants with optical repeaters or with internal antenna distribution. We are able to implement large-scale projects for the internal coverage of halls, tunnels, exhibition grounds, airports, congress centers and other places that are difficult to reach for the GSM signal, or it is not economically worthwhile to cover these places with classic BTS stations. Deliveries were made in the range of dozens of repeaters and hundreds of antennas.
