Router

However, getting the full 900Mbps over Wi-Fi is not always possible, especially in rooms farther from the router. Complete Wi-Fi Plus is available if you need to extend Wi-Fi coverage to other parts of your home.
Digital Voice
You don’t have to take a home phone with Full Fibre 900. If you need one, BT’s Digital Voice service lets you make calls using your internet connection. You can keep a compatible telephone and usually retain your existing number. Remember that your broadband and router must be working to make calls.
BT TV
Full Fibre 900 has far more speed than you need for watching 4K TV. Even if your family watches programmes on several screens, there is plenty of bandwidth left for downloading files and other internet activities. You can choose a BT TV package with the TV Box Pro for recording programmes or the TV Box Edge if you don’t need recording.

The 900Mbps download speed can download a 100GB game in about 15 minutes under ideal conditions. Several people can play online simultaneously, while the 110Mbps upload speed is great for live game streaming. Actual gaming ping and download times depend on the server and network conditions.
Alternatives to consider
