For your dormitory building, whether you can enjoy a gigabit broadband depends on many factors, including but not limited to: users' online habits: if most users only do basic web browsing, social media interaction and some lightweight online activities, then broadband with a downlink speed limit of 5M and an uplink speed limit of 2M may be enough. However, if users often download large files, play online games or other activities that require high bandwidth, this speed may not be enough.

Network management strategy: If the dormitory network traffic is managed and allocated reasonably, even if the bandwidth is limited, traffic shaping and priority control can be used to ensure that the network needs of key businesses and time periods can be met.

Network equipment performance: If the network equipment (such as routers and switches) from the company's computer room to the dormitory supports high-speed data transmission, the network wiring can meet the gigabit network transmission standard, which can theoretically meet the demand.

Standby network capacity: In general, a certain bandwidth margin will be reserved in network planning to cope with possible future growth or sudden traffic peak.

To sum up, whether a gigabit broadband with a downlink speed limit of 5M and an uplink speed limit of 2M can meet the network demand of the dormitory requires comprehensive consideration of factors such as the actual use of users, network management strategy, network equipment performance, backup network capacity and so on. It is suggested that you consult a professional network administrator or technician for detailed network traffic analysis and evaluation to ensure that the network bandwidth can meet the needs of the dormitory. ?
