Virgin Media's ultrafast broadband network is now available to up to 2,400 homes and businesses in New Milton and Highcliffe, near Christchurch.
According to the network provider, the infrastructure upgrade will give people in the area access to speeds of up to 350Mbps.
This, it said, will transform the quality of local broadband, where the average download speed had previously stood at just 23.5Mbps.
Virgin Media stated that, with a 350Mbps connection, households will be able to download a standard HD movie file (5GB) in about two minutes. This compares with more than 30 minutes on the previous average local connection.
Similarly, the time it takes to download a 25GB console game has fallen from more than two-and-a-half hours to just over ten minutes.
The gigabit-capable lines will also enable local people to sign up to Virgin TV and use its 4K-ready V6 set-top box.
As a result, residents will be able to access up to 260 TV channels, including up to 50 HD channels, Sky Movies, Netflix and all the football from Sky Sports and BT Sports, as well as an extensive selection of box sets and movies.
Cormac Connolly, Regional Director at Virgin Media, commented: "We are delighted that local residents and businesses across New Milton and Highcliffe can now start to benefit from the boost our ultrafast broadband will give them."
He added that giving them faster broadband speeds will enable them "to do the things they need to do and love doing more quickly and more easily".
This comes shortly after Virgin Media confirmed its ultrafast broadband network is now available to up to 4,900 homes and businesses in Margate and Ramsgate, where the average download speed had previously stood at just 19.3Mbps.
