AT&T has expanded its use of carrier aggregation to include major markets such as New York, San Francisco and Dallas.
With just a few weeks on the job, Tom Keathley is already well-versed in all aspects of AT&T's network. Keathley, a long-time AT&T veteran, was named the company's senior vice president of network and product planning replacing Kris Rinne, who retired at the end of November. Keathley recently spoke with FierceWirelessTech Editor in Chief Sue Marek about the company's progress with carrier aggregation and VoLTE and shared his vision of 5G and the future of the wireless network. The following is an excerpt of that conversation.
SK Telecom announced that it launched commercial tri-band LTE-Advanced (LTE-A) service, which the carrier said was a world's first.

2014 is nearly at and end and it's the time of the year when there are countless year-end review articles and 2015 predictions. While there were many highlights of 2014, I choose to hone in on network and competition. Instead of predictions, my 2015 expectations have been laid out with technology paths and the previous year's events.

AT&T Mobility is going to deploy carrier aggregation technology where it can, depending on how much spectrum it has available to meld together, according to a senior company executive.
Thanks to an exclusive partnership between FierceWireless and network testing firm RootMetrics, readers will be able to see the maximum recorded downlink and uplink speeds the firm observed for the four Tier 1 carriers across eight different regions in the U.S. The data also lets readers see which regions of the country in general let wireless customers access the highest peak downlink and uplink speeds. RootMetrics conducted extensive testing across the country both in the first half of 2014 and in the third quarter to gauge how the four Tier 1 carriers fared in terms of maximum downlink and uplink speeds.
ABI Research estimates that 676 million 4G LTE handsets will be shipped in 2015, increasing by 204 million units from 2014.
