There is some interesting news from Australia regarding LTE (News - Alert) that is more than a tad noteworthy. In a Telstra company blog, Mike Wright, Executive Director – Networks & Access Technologies, revealed that in its latest test of LTE-Advance Carrier Aggregation, the company achieved download speeds of 300 Mbps. Very impressive.
For those unfamiliar, LTE-Advance Carrier Aggregation (LTE-A for short) involves aggregating two channels of 20MHz spectrum. In the trial conducted on the company’s live commercial 4G network, Telstra (News - Alert) aggregated 20 MHz bandwidth within the 1800 MHz spectrum band and 20 MHz bandwidth within the 2600 MHz band. Back in July the company was the first one to use LTE-A in the 900 MHz and 1800 MHz bands.
As Wright explained, “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.”
Telstra is in the midst of a rapid 4G LTE deployment. In fact, it is just a few hundred base stations short of providing 85 percent of its operating area 4G services by the end of the year. Wright says that Telstra does not just wish to provide 4G across its entire footprint, but wants to push the envelope as to the speeds that can be delivered across it. He added, “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.”
Talk about, “The Thunder Down Under.”
