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.
Carrier aggregation, network twinning and LTE-Unlicnesed are in various states of deployment and development-- and they're all ultimately win-wins for both mobile carriers and users.
Ericsson and China Mobile are claiming an industry first in Beijing with the live demonstration of LTE TDD three carrier aggregation, including 256 QAM modulation scheme to increase speeds even more.
Apple unveiled its new iPhone 6s and iPhone 6s Plus, which the company said feature 3D Touch that "senses force to enable intuitive new ways to access features and interact with content." The devices also sport Retina HD displays, 7000 series aluminum, and 12-megapixel cameras. Importantly, the phones support fully 23 bands of LTE, including the 700 MHz band 12 that T-Mobile US is using and Sprint's 2.5 GHz carrier aggregation.
