Telecommunications and infrastructure
Telecommunications and network infrastructure form the basis of most Charles University services, from internet connection via Wi-Fi to secure VPN, university telephony or central network elements.
This section will help you understand what services CU provides, who manages them and who to contact if something is not working.
How telecommunications infrastructure works at the CU
Faculty IT Department
Manages local Wi-Fi coverage, cable distribution and network in buildings.
Solves connectivity problems in classrooms, offices and workrooms.
Provides connection configuration for user devices.
Sets up local network drives, printing and other faculty services.
Information and Communication Technologies
Manages the UK's central network infrastructure.
Operates Eduroam, VPN, UK-events and central routing elements.
Provides university telephony - fixed lines and mobile services.
