nbnCo has conducted a demonstration in Ballarat, in central Victoria, where they achieved 1.1Gbps downstream and 165Mbps upstream speeds by using Carrier Aggregation technology. This fused seven carriers in the 3.4GHz spectrum band and four carriers in the 2.3GHz spectrum band.
As part of the demonstration nbn also delivered trial peak speeds of 400Mbps/55Mbps, 250Mbps/50Mbps and 100/40Mbps, all delivered using a range of carriers in the 2.3GHz and 3.4GHz spectrum bands.
Given nbnCo promises to deliver a new nbn100 Fixed Wireless product aimed at the regional business segment in 2018, it's good to see them pushing the boundaries of what wireless can do.
This is all great, and it is important that research and development continues in developing faster connection options, particularly for locations where fixed connections aren't viable. It could provide a way to distribute capacity to remote locations where the last mile is carried using some other wireless or even fixed connection.
It will take a while before we see this kind of tech widely deployed as it requires equipment deployment on cell towers as well as appropriate receivers to be made and marketed.
But it's a big step up from when 40Mbps connections were all the rage a few years ago.
