There is a robust network in each apartment. Many walls will have at least 3 ethernet jacks where you can plug in networked devices. All of these lines are cat-8, and will plug into 10GBPS network switches. This is designed to not be the bottleneck. Most consumer grade networking capabilities is limited to 1GBPS. When that happens, the connection will use the slowest speed of the connected units. Therefore, a 1,000MBPS computer is sending a print job to a printer with a 100MBPS connection, then the connection speed is 100MBPS even though the switch is 10GBPS.
There will also be the latest wifi connection possible. This will be an access point that will be in the center of the unit to provide for maximum coverage of the apartment. At the very worst, there might be a dead spot in the far reaches of the apartment, but this will be unlikely. When you applied for the apartment, one of the things is you were to provide some credentials. This included the network SSID, network passphrase, and server password. You would have also be asked if you wish to setup a guest network. If so, the network will be appended with -g. Therefore, if you SSID is fsp, then your guest SSID is fsp-g. If you have some experience with networking servers, you can set things like static IP addresses for certain devices. This is unnecessary for most devices, but it might be handy for ATAs, Wifi Phones, and NAS systems.
