Data communications are provided by several companies. Telstra was the first company to provide dial-up Internet access via the Ballarat exchange, however the first network for broadband Internet access available in the city was a hybrid optical fiber cable and coaxial cable built by Neighbourhood Cable in 2001. Since then, Telstra and Optus have entered the Ballarat market, providing Asymmetric digital subscriber line (ADSL) services for residential Internet access from four main exchanges—Ballarat, Wendouree (Howitt Street), Sebastopol (Skipton Street) and Alfredton (Cuthberts Road). These companies also provide mobile data access Evolved HSPA and since late 2011 3GPP Long Term Evolution (4G). Ballarat's rollout of the National Broadband Network (NBN) is seen as vital for the city's growing IT industry. During Ballarat's first stage NBN rollout in 2012, 17,800 homes will be directly connected to the network via optical fibre cable.
