Given all the talk and momentum around 5G, it's easy to forget that LTE and LTE-Advanced still have a long life ahead. Operators in the United States, like AT&T, have long stressed the importance of seeing 5G through the standards process before anybody gets too gung-ho about the prospects for full-blown commercial 5G networks.
Nokia announced it completed the first commercial deployment of FDD-TDD carrier aggregation (CA) in Russia after a launch on MTS' LTE network in Moscow.
T-Mobile Netherlands launched a trial of three-band carrier aggregation (3CA) on its LTE-Advanced (LTE-A) network in Woerden to demonstrate the capacity and speed benefits of bundling three spectrum bands together.
T-Mobile US is testing carrier aggregation technology across three different spectrum bands, a move that could significantly improve the speed and performance of the operator's LTE network.
SFR launched 4G or LTE Advanced services at maximum download speeds of 337.5 Mbps following the implementation of tri-band carrier aggregation (CA) technology into the company's network.
Nearly 40 percent of voice calls on T-Mobile's network are transmitted via Voice over LTE (VoLTE), illustrating how aggressively the carrier is pursuing the technology.
Ericsson said a demonstration of LTE carrier aggregation conducted on the live Cosmote Greece network is a first for Europe after data download rates hit 500 Mbps.
Sprint is rebranding part of its LTE network and said that it has now deployed carrier aggregation and beamforming technology in 77 "major" markets across the country, in what it calls an "LTE Plus" deployment. The carrier will continue using LTE Advanced techniques to make its network faster and more robust, according to Sprint CTO John Saw.
Sprint is in the middle of its turnaround but has a lot of cause for optimism, according to CFO Tarek Robbiati, who promised that the carrier will continue to make improvements in churn and its network.
Sprint is seeing positive early results from its plans to densify its network, but the company's executives did not provide many details about how far along the project is and how long it will take.
