We design and install computer and communication networks. We are experienced in building computer and communication networks from the year 1993. We have many specialists with over ten years of experience. We install the computer network based on the components of their manufacturers with long-term guarantee (e.g. 25 years in case of Excel-Networking) as well as computer network based on the components of their manufacturers without such long guarantee, but the cost is more favourable and quality is meeting all requirements.
