Data Centers


    A data center is a server room or big building that is a physical facility that organizations use to house their critical applications and data. 


    A data center houses IT network infrastructure for building, running, services, and for storing and managing the data associated with those applications and services. The core equipments of a data center design include switches, routers, firewalls, servers, storage systems, UPS, and more. 


    A data center might extend outside of a physical facility by using a private or public cloud to augment its operations or storage. A virtualized data center can use servers in remote locations when needed to run larger workloads.

5G Network


    5G is the fifth generation technology standard for broadband cellular networks, It is designed to increase speed, reduce latency, and improve flexibility of wireless services. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. In addition to 5G being faster than existing networks, 5G can connect more different devices, and even if people are in crowded areas, the servers will be more unified, improving the quality of Internet services.

    The WiFi 6 wireless standard shares traits with 5G, including improved performance. WiFi 6 radios can be placed where users need them to provide better geographical coverage and lower cost. Underlying these WiFi 6 radios is a software network with advanced automation.
