Networking infrastructure is the foundation from which systems are linked or networked together. It most often consists of fiber optic cables, UTP, data switching, and Wi-Fi technology. Thus, most commonly, it is the hardware and software which enables network connectivity and communication between users, devices, applications, and the Internet. Most organizations use NW Infrastructure to connect the various departments of their respective organizations, and to communicate with customers and suppliers. That is why they require systems of the highest quality that often use high resolution for video conferences, and IP phone systems between departments, and sometimes organizations, that allow for a large amount of data transmission. It is incumbent on this organization to ensure that all network infrastructure which we have been entrusted to install is stable and reliable, and adaptable enough to support various changes for expansion in the future. The employees of First One Systems Co., Ltd, work together with our business partners whose latest technology and innovations are at the forefront of this industry. Among these vanguard industries are Alcatel Lucent Enterprise, Huawei, and Cisco Systems.
