blog Just how fast can 4G mobile broadband go? Very fast, according to Telstra, which has been conducting trials of LTE-Advanced Carrier Aggregation technology. The company’s executive director of networks and access technologies, total geek and all-round good guy Mike Wright, writes on Telstra’s Exchange blog:
“Back in August I wrote about the possibilities of LTE- Advanced Carrier Aggregation which allows greater data download speeds by aggregating spectrum across the two spectrum bands and this morning we were able to see this in action, live on our commercial 4G network, by aggregating two channels of 20MHz spectrum to achieve download speeds of up to 300 Mbps in a trial environment.
The trial was conducted using a commercial test device and aggregating 20 MHz bandwidth within the 1800 MHz spectrum band and 20 MHz bandwidth within the 2600 MHz band.
While these trial speeds are very impressive and exciting (and we expect that actual typical customer speeds on commercial services will be lower), these trials are important for another reason as they build on our earlier LTE-Advanced work and set us up to continue to deliver a reliable network experience and more reliable speeds into the future. We have all seen around the world what happens when operators can’t keep up with customer demand. Without a strong, multi-year strategy the rapid rate of data growth would quickly swamp any new network rollout.
As we move into 2014 we will use these trials to inform the development of our network and the early launch of devices that will be ready for the combined APT700 MHz and LTE1800 spectrum bands.”
Now, I think we can all agree, and Wright already warned us, that these won’t quite be the speeds which we’ll be seeing in the wild, and before we get into any NBN-related discussions, let me remind readers that wireless technologies such as mobile broadband are complementary to fixed broadband services, due to wireless’ issues with concurrent usage, cost and so on. Although these kinds of technologies may drive some users to purely mobile usage patterns, overall data growth will continue to push most users to get better usage out of their fixed broadband networks.
But lookit! It sure is cool that Telstra can do this over 4G! Yes please! Mike, can you blanket Sydney with this, ASAP? Pretty please?
