It is true that the internet customers in the United States will soon be able to enjoy 5G in the near future, but that doesn’t mean that the LTE, the 4G technology that we love and know, is done, at least for now. LTE-Advanced, which is the name assigned to a number of innovative new technologies by leading internet providers, can still offer a better internet using experience to subscribers.
In a recent earnings call, the CFO of AT&T®, John Stephens announced that the telecom company would be deploying LTE-Advanced technologies to approximately 20 cities in the country and all the new networks will start to run by the end of this year. Reports from several reliable sources indicate that the telecom giant is eyeing to offer a maximum internet speed of 400 Mbps to their internet customers. The average internet speed available to customers due to the implementation of these new technologies is estimated to be around 40 Mbps, which is twice as high as the current average internet speed offered by AT&T®.
Officials from the telecom company also hinted that they are planning to combine three new technologies and use them for capacity upgrades and to deliver impressive internet speed. Some of the best internet providers in the country, including AT&T®, have been using the technology of carrier aggregation for quite a few years. This innovative technology efficiently combines more than one chunk of LTE spectrum across a wide range of frequencies, thereby allowing handsets to access and download data from different LTE bands at the very same time. 2CA, which aggregates two different carriers together, has already gained popularity among Americans.
Another new technology pushed out by AT&T®, Multiple Input Multiple Output (MIMO), combines data streams from multiple antennas in order to boost the entire bitrate available to users. In addition to that, it also partners exceptionally well with carrier aggregation.
The final piece of the puzzle, LTE-Licensed Assisted Access (LAA) is critical, as it efficiently combines unlicensed 5 GHz spectrum with the usual LTE frequencies. This enables AT&T® to deploy small cell towers, which use 5 GHz in order to communicate with multiples devices in the close vicinity. This in turn significantly reduces the load on the traditional LTE network of AT&T®.
Experts believe that these technologies will be critically important during the rollout of 5G too. Therefore, incorporating the use of these technologies in the existing networks is certainly a smart move.
